LPC1111/12/13/14
NXP Semiconductors
32-bit ARM Cortex-M0 microcontroller
• In the LPC1111/12/13/14, the NVIC supports 32 vectored interrupts including up to 13
inputs to the start logic from individual GPIO pins.
• Four programmable interrupt priority levels, with hardware priority level masking.
• Relocatable vector table.
• Software interrupt generation.
7.5.2 Interrupt sources
Each peripheral device has one interrupt line connected to the NVIC but may have several
interrupt flags. Individual interrupt flags may also represent more than one interrupt
source.
Any GPIO pin (total of up to 42 pins) regardless of the selected function, can be
programmed to generate an interrupt on a level, or rising edge or falling edge, or both.
7.6 IOCONFIG block
The IOCONFIG block allows selected pins of the microcontroller to have more than one
function. Configuration registers control the multiplexers to allow connection between the
pin and the on-chip peripherals.
Peripherals should be connected to the appropriate pins prior to being activated and prior
to any related interrupt(s) being enabled. Activity of any enabled peripheral function that is
not mapped to a related pin should be considered undefined.
7.7 Fast general purpose parallel I/O
Device pins that are not connected to a specific peripheral function are controlled by the
GPIO registers. Pins may be dynamically configured as inputs or outputs. Multiple outputs
can be set or cleared in one write operation.
LPC1111/12/13/14 use accelerated GPIO functions:
• GPIO registers are a dedicated AHB peripheral so that the fastest possible I/O timing
can be achieved.
• Entire port value can be written in one instruction.
Additionally, any GPIO pin (total of up to 42 pins) providing a digital function can be
programmed to generate an interrupt on a level, a rising or falling edge, or both.
7.7.1 Features
• Bit level port registers allow a single instruction to set or clear any number of bits in
one write operation.
• Direction control of individual bits.
• All I/O default to inputs with pull-ups enabled after reset.
• Pull-up/pull-down resistor configuration can be programmed through the IOCONFIG
block for each GPIO pin.

and one SPI controller on the HVQFN33 packages (SPI0). Both SPI controllers support
SSP features.
The SPI controller is capable of operation on a SSP, 4-wire SSI, or Microwire bus. It can
interact with multiple masters and slaves on the bus. Only a single master and a single
slave can communicate on the bus during a given data transfer. The SPI supports full
duplex transfers, with frames of 4 bits to 16 bits of data flowing from the master to the
slave and from the slave to the master. In practice, often only one of these data flows
carries meaningful data.
7.9.1 Features
• Maximum SPI speed of 25 Mbit/s (master) or 4.17 Mbit/s (slave) (in SSP mode)
• Compatible with Motorola SPI, 4-wire Texas Instruments SSI, and National
Semiconductor Microwire buses
• Synchronous serial communication
• Master or slave operation
• 8-frame FIFOs for both transmit and receive
• 4-bit to 16-bit frame
7.10 I2C-bus serial I/O controller

The I2C-bus is bidirectional for inter-IC control using only two wires: a Serial Clock Line
(SCL) and a Serial DAta line (SDA). Each device is recognized by a unique address and
can operate as either a receiver-only device (e.g., an LCD driver) or a transmitter with the
capability to both receive and send information (such as memory). Transmitters and/or

The LPC1111/12/13/14 includes two 32-bit counter/timers and two 16-bit counter/timers.
The counter/timer is designed to count cycles of the system derived clock. It can optionally
generate interrupts or perform other actions at specified timer values, based on four
match registers. Each counter/timer also includes one capture input to trap the timer value
when an input signal transitions, optionally generating an interrupt.

7.13 System tick timer
The ARM Cortex-M0 includes a system tick timer (SYSTICK) that is intended to generate
a dedicated SYSTICK exception at a fixed time interval (typically 10 ms).
7.14 Watchdog timer
The purpose of the watchdog is to reset the microcontroller within a selectable time
period.
7.14.1 Features
• Internally resets chip if not periodically reloaded.
• Debug mode.
• Enabled by software but requires a hardware reset or a watchdog reset/interrupt to be
disabled.
• Incorrect/Incomplete feed sequence causes reset/interrupt if enabled.
• Flag to indicate watchdog reset.
• Programmable 32-bit timer with internal prescaler.
• Selectable time period from (Tcy(WDCLK) × 256 × 4) to (Tcy(WDCLK) × 232 × 4) in
multiples of Tcy(WDCLK) × 4.
• The Watchdog Clock (WDCLK) source can be selected from the Internal RC oscillator
(IRC), the Watchdog oscillator, or the main clock. This gives a wide range of potential
timing choices of Watchdog operation under different power reduction conditions. It
also provides the ability to run the WDT from an entirely internal source that is not
dependent on an external crystal and its associated components and wiring for
increased reliability.

7.15.1 Crystal oscillators
The LPC1111/12/13/14 include three independent oscillators. These are the system
oscillator, the Internal RC oscillator (IRC), and the Watchdog oscillator. Each oscillator can
be used for more than one purpose as required in a particular application.
Following reset, the LPC1111/12/13/14 will operate from the Internal RC oscillator until
switched by software. This allows systems to operate without any external crystal and the
bootloader code to operate at a known frequency.

7.15.1.1 Internal RC oscillator
The IRC may be used as the clock source for the WDT, and/or as the clock that drives the
PLL and subsequently the CPU. The nominal IRC frequency is 12 MHz. The IRC is
trimmed to 1 % accuracy over the entire voltage and temperature range.

NXP Semiconductors
32-bit ARM Cortex-M0 microcontroller
Upon power-up or any chip reset, the LPC1111/12/13/14 use the IRC as the clock source.
Software may later switch to one of the other available clock sources.
7.15.1.2 System oscillator
The system oscillator can be used as the clock source for the CPU, with or without using
the PLL.
The system oscillator operates at frequencies of 1 MHz to 25 MHz. This frequency can be
boosted to a higher frequency, up to the maximum CPU operating frequency, by the
system PLL.
7.15.1.3 Watchdog oscillator
The watchdog oscillator can be used as a clock source that directly drives the CPU, the
watchdog timer, or the CLKOUT pin. The watchdog oscillator nominal frequency is
programmable between 7.8 kHz and 1.7 MHz. The frequency spread over processing and
temperature is ±40 %.
7.15.2 System PLL
The PLL accepts an input clock frequency in the range of 10 MHz to 25 MHz. The input
frequency is multiplied up to a high frequency with a Current Controlled Oscillator (CCO).
The multiplier can be an integer value from 1 to 32. The CCO operates in the range of
156 MHz to 320 MHz, so there is an additional divider in the loop to keep the CCO within
its frequency range while the PLL is providing the desired output frequency. The output
divider may be set to divide by 2, 4, 8, or 16 to produce the output clock. Since the
minimum output divider value is 2, it is insured that the PLL output has a 50 % duty cycle.
The PLL is turned off and bypassed following a chip reset and may be enabled by
software. The program must configure and activate the PLL, wait for the PLL to lock, and
then connect to the PLL as a clock source. The PLL settling time is 100 μs.
7.15.3 Clock output
The LPC1111/12/13/14 features a clock output function that routes the IRC oscillator, the
system oscillator, the watchdog oscillator, or the main clock to an output pin.
7.15.4 Wake-up process
The LPC1111/12/13/14 begin operation at power-up and when awakened from Deep
power-down mode by using the 12 MHz IRC oscillator as the clock source. This allows
chip operation to resume quickly. If the system oscillator or the PLL is needed by the
application, software will need to enable these features and wait for them to stabilize
before they are used as a clock source.
7.15.5 Power control
The LPC1111/12/13/14 support a variety of power control features. There are three
special modes of processor power reduction: Sleep mode, Deep-sleep mode, and Deep
power-down mode. The CPU clock rate may also be controlled as needed by changing
clock sources, reconfiguring PLL values, and/or altering the CPU clock divider value. This
allows a trade-off of power versus processing speed based on application requirements.
In addition, a register is provided for shutting down the clocks to individual on-chip
peripherals, allowing fine tuning of power consumption by eliminating all dynamic power
use in any peripherals that are not required for the application. Selected peripherals have
their own clock divider which provides even better power control.

NXP Semiconductors
32-bit ARM Cortex-M0 microcontroller
7.15.5.1 Sleep mode
When Sleep mode is entered, the clock to the core is stopped. Resumption from the Sleep
mode does not need any special sequence but re-enabling the clock to the ARM core.
In Sleep mode, execution of instructions is suspended until either a reset or interrupt
occurs. Peripheral functions continue operation during Sleep mode and may generate
interrupts to cause the processor to resume execution. Sleep mode eliminates dynamic
power used by the processor itself, memory systems and related controllers, and internal
buses.
7.15.5.2 Deep-sleep mode
In Deep-sleep mode, the chip is in Sleep mode, and in addition analog blocks can be shut
down for increased power savings. The user can configure the Deep-sleep mode to a
large extent, selecting any of the oscillators, the PLL, BOD, the ADC, and the flash to be
shut down or remain powered during Deep-sleep mode. The user can also select which of
the oscillators and analog blocks will be powered up after the chip exits from Deep-sleep
mode.
The GPIO pins (up to 15 pins total) serve as external wake-up pins to a dedicated start
logic to wake up the chip from Deep-sleep mode.
The timing of the wake-up process from Deep-sleep mode depends on which blocks are
selected to be powered down during deep-sleep.
For lowest power consumption, the clock source should be switched to IRC before
entering Deep-sleep mode, all oscillators and the PLL should be turned off during
deep-sleep, and the IRC should be selected as clock source when the chip wakes up from
deep-sleep. The IRC can be switched on and off glitch-free and provides a clean clock
signal after start-up.
If power consumption is not a concern, any of the oscillators and/or the PLL can be left
running in Deep-sleep mode to obtain short wake-up times when waking up from
deep-sleep.
7.15.5.3 Deep power-down mode
In Deep power-down mode, power is shut off to the entire chip with the exception of the
WAKEUP pin. The LPC1111/12/13/14 can wake up from Deep power-down mode via the
WAKEUP pin.
7.16 System control
7.16.1 Reset
Reset has four sources on the LPC1111/12/13/14: the RESET pin, the Watchdog reset,
power-on reset (POR), and the BrownOut Detection (BOD) circuit. The RESET pin is a
Schmitt trigger input pin. Assertion of chip reset by any source, once the operating voltage
attains a usable level, starts the IRC and initializes the flash controller.
When the internal Reset is removed, the processor begins executing at address 0, which
is initially the Reset vector mapped from the boot block. At that point, all of the processor
and peripheral registers have been initialized to predetermined values.

7.16.2 Brownout detection
The LPC1111/12/13/14 includes four levels for monitoring the voltage on the VDD pin. If
this voltage falls below one of the four selected levels, the BOD asserts an interrupt signal
to the NVIC. This signal can be enabled for interrupt in the Interrupt Enable Register in the
NVIC in order to cause a CPU interrupt; if not, software can monitor the signal by reading
a dedicated status register. Four additional threshold levels can be selected to cause a
forced reset of the chip.
7.16.3 Code security (Code Read Protection - CRP)
This feature of the LPC1111/12/13/14 allows user to enable different levels of security in
the system so that access to the on-chip flash and use of the Serial Wire Debugger (SWD)
and In-System Programming (ISP) can be restricted. When needed, CRP is invoked by
programming a specific pattern into a dedicated flash location. IAP commands are not
affected by the CRP.
In addition, ISP entry via the PIO0_1 pin can be disabled without enabling CRP. For
details see the LPC111x user manual.
There are three levels of Code Read Protection:
1. CRP1 disables access to the chip via the SWD and allows partial flash update
(excluding flash sector 0) using a limited set of the ISP commands. This mode is
useful when CRP is required and flash field updates are needed but all sectors can
not be erased.
2. CRP2 disables access to the chip via the SWD and only allows full flash erase and
update using a reduced set of the ISP commands.
3. Running an application with level CRP3 selected fully disables any access to the chip
via the SWD pins and the ISP. This mode effectively disables ISP override using
PIO0_1 pin, too. It is up to the user’s application to provide (if needed) flash update
mechanism using IAP calls or call reinvoke ISP command to enable flash update via
the UART.
CAUTION
If level three Code Read Protection (CRP3) is selected, no future factory testing can be
performed on the device.
In addition to the three CRP levels, sampling of pin PIO0_1 for valid user code can be
disabled. For details see the LPC111x user manual.
7.16.4 APB interface
The APB peripherals are located on one APB bus.
7.16.5 AHBLite

7.16.6 External interrupt inputs
All GPIO pins can be level or edge sensitive interrupt inputs.
7.16.7 Memory mapping control
The Cortex-M0 incorporates a mechanism that allows remapping the interrupt vector table
to alternate locations in the memory map. This is controlled via the Vector Table Offset
Register contained in the NVIC.
The vector table may be located anywhere within the bottom 1 GB of Cortex-M0 address
space. The vector table must be located on a 128 word (512 byte) boundary.
7.17 Emulation and debugging
Debug functions are integrated into the ARM Cortex-M0. Serial wire debug with four
breakpoints and two watchpoints is supported.

[1] The ADC is monotonic, there are no missing codes.
[2] The differential linearity error (ED) is the difference between the actual step width and the ideal step width. See Figure 7.
[3] The integral non-linearity (EL(adj)) is the peak difference between the center of the steps of the actual and the ideal transfer curve after
appropriate adjustment of gain and offset errors. See Figure 7.
[4] The offset error (EO) is the absolute difference between the straight line which fits the actual curve and the straight line which fits the
ideal curve. See Figure 7.
[5] The gain error (EG) is the relative difference in percent between the straight line fitting the actual transfer curve after removing offset
error, and the straight line which fits the ideal transfer curve. See Figure 7.
[6] The absolute error (ET) is the maximum difference between the center of the steps of the actual transfer curve of the non-calibrated
ADC and the ideal transfer curve. See Figure 7.
[7] Tamb = 25 °C; maximum sampling frequency fs = 4.5 MHz and analog input capacitance Cia = 1 pF.
[8] Input resistance Ri depends on the sampling frequency fs: Ri = 1 / (fs × Cia).

[6] The maximum tf for the SDA and SCL bus lines is specified at 300 ns. The maximum fall time for the SDA
output stage tf is specified at 250 ns. This allows series protection resistors to be connected in between the
SDA and the SCL pins and the SDA/SCL bus lines without exceeding the maximum specified tf.
[7] In Fast-mode Plus, fall time is specified the same for both output stage and bus timing. If series resistors
are used, designers should allow for this when considering bus timing.
[8] The maximum tHD;DAT could be 3.45 μs and 0.9 μs for Standard-mode and Fast-mode but must be less than
the maximum of tVD;DAT or tVD;ACK by a transition time (see UM10204). This maximum must only be met if
the device does not stretch the LOW period (tLOW) of the SCL signal. If the clock stretches the SCL, the
data must be valid by the set-up time before it releases the clock.
[9] tSU;DAT is the data set-up time that is measured with respect to the rising edge of SCL; applies to data in
transmission and the acknowledge.
[10] A Fast-mode I2C-bus device can be used in a Standard-mode I2C-bus system but the requirement tSU;DAT
=
250 ns must then be met. This will automatically be the case if the device does not stretch the LOW period
of the SCL signal. If such a device does stretch the LOW period of the SCL signal, it must output the next
data bit to the SDA line tr(max) + tSU;DAT = 1000 + 250 = 1250 ns (according to the Standard-mode I2C-bus
specification) before the SCL line is released. Also the acknowledge timing must meet this set-up time.

11. Application information
11.1 ADC usage notes
The following guidelines show how to increase the performance of the ADC in a noisy
environment beyond the ADC specifications listed in Table 8:
• The ADC input trace must be short and as close as possible to the LPC1111/12/13/14
chip.
• The ADC input traces must be shielded from fast switching digital signals and noisy
power supply lines.
• Because the ADC and the digital core share the same power supply, the power supply
line must be adequately filtered.
• To improve the ADC performance in a very noisy environment, put the device in Sleep
mode during the ADC conversion.
11.2 XTAL input
The input voltage to the on-chip oscillators is limited to 1.8 V. If the oscillator is driven by a
clock in slave mode, it is recommended that the input be coupled through a capacitor with
Ci = 100 pF. To limit the input voltage to the specified range, choose an additional
capacitor to ground Cg which attenuates the input voltage by a factor Ci/(Ci + Cg). In slave
mode, a minimum of 200 mV(RMS) is needed.

100 pF
002aae788
Fig 24. Slave mode operation of the on-chip oscillator
In slave mode the input clock signal should be coupled by means of a capacitor of 100 pF
(Figure 24), with an amplitude between 200 mV(RMS) and 1000 mV(RMS). This
corresponds to a square wave signal with a signal swing of between 280 mV and 1.4 V.
The XTALOUT pin in this configuration can be left unconnected.
External components and models used in oscillation mode are shown in Figure 25 and in
Table 17 and Table 18. Since the feedback resistance is integrated on chip, only a crystal
and the capacitances CX1 and CX2 need to be connected externally in case of
fundamental mode oscillation (the fundamental frequency is represented by L, CL and
RS). Capacitance CP in Figure 25 represents the parallel package capacitance and should
not be larger than 7 pF. Parameters FOSC, CL, RS and CP are supplied by the crystal
manufacturer (see Table 17).

11.3 XTAL Printed Circuit Board (PCB) layout guidelines
The crystal should be connected on the PCB as close as possible to the oscillator input
and output pins of the chip. Take care that the load capacitors Cx1, Cx2, and Cx3 in case of
third overtone crystal usage have a common ground plane. The external components
must also be connected to the ground plain. Loops must be made as small as possible in

order to keep the noise coupled in via the PCB as small as possible. Also parasitics
should stay as small as possible. Values of Cx1 and Cx2 should be chosen smaller
accordingly to the increase in parasitics of the PCB layout.
