DESCRIPTION
The CC2540 is a cost-effective, low-power, true system-on-chip (SoC) for Bluetooth low energy applications. It
enables robust BLE master or slave nodes to be built with very low total bill-of-material costs. The CC2540
combines an excellent RF transceiver with an industry-standard enhanced 8051 MCU, in-system programmable
flash memory, 8-KB RAM, and many other powerful supporting features and peripherals. The CC2540 is suitable
for systems where very low power consumption is required. Very low-power sleep modes are available. Short
transition times between operating modes further enable low power consumption.
The CC2540 comes in two different versions: CC2540F128/F256, with 128 and 256 KB of flash memory,
respectively.
Combined with the Bluetooth low energy protocol stack from Texas Instruments, the CC2540F128/F256 forms
the market’s most flexible and cost-effective single-mode Bluetooth low energy solution.

This integrated circuit can be damaged by ESD. Texas Instruments recommends that all integrated circuits be handled with
appropriate precautions. Failure to observe proper handling and installation procedures can cause damage.
ESD damage can range from subtle performance degradation to complete device failure. Precision integrated circuits may be more
susceptible to damage because very small parametric changes could cause the device not to meet its published specifications.

BLOCK DESCRIPTIONS
CPU and Memory
The 8051 CPU core is a single-cycle 8051-compatible core. It has three different memory access busses (SFR,
DATA, and CODE/XDATA), a debug interface, and an 18-input extended interrupt unit.
The memory arbiter is at the heart of the system, as it connects the CPU and DMA controller with the physical
memories and all peripherals through the SFR bus. The memory arbiter has four memory-access points, access
of which can map to one of three physical memories: an SRAM, flash memory, and XREG/SFR registers. It is
responsible for performing arbitration and sequencing between simultaneous memory accesses to the same
physical memory.
The SFR bus is drawn conceptually in Figure 8 as a common bus that connects all hardware peripherals to the
memory arbiter. The SFR bus in the block diagram also provides access to the radio registers in the radio
register bank, even though these are indeed mapped into XDATA memory space.
The 8-KB SRAM maps to the DATA memory space and to parts of the XDATA memory spaces. The SRAM is
an ultralow-power SRAM that retains its contents even when the digital part is powered off (power modes 2 and
3).
The 128/256 KB flash block provides in-circuit programmable non-volatile program memory for the device, and
maps into the CODE and XDATA memory spaces.
Peripherals
Writing to the flash block is performed through a flash controller that allows page-wise erasure and 4-bytewise
programming. See User Guide for details on the flash controller.
A versatile five-channel DMA controller is available in the system, accesses memory using the XDATA memory
space, and thus has access to all physical memories. Each channel (trigger, priority, transfer mode, addressing
mode, source and destination pointers, and transfer count) is configured with DMA descriptors that can be
located anywhere in memory. Many of the hardware peripherals (AES core, flash controller, USARTs, timers,
ADC interface, etc.) can be used with the DMA controller for efficient operation by performing data transfers
between a single SFR or XREG address and flash/SRAM.
Each CC2540 contains a unique 48-bit IEEE address that can be used as the public device address for a
Bluetooth device. Designers are free to use this address, or provide their own, as described in the Bluetooth
specfication.
The interrupt controller services a total of 18 interrupt sources, divided into six interrupt groups, each of which
is associated with one of four interrupt priorities. I/O and sleep timer interrupt requests are serviced even if the
device is in a sleep mode (power modes 1 and 2) by bringing the CC2540 back to the active mode.
The debug interface implements a proprietary two-wire serial interface that is used for in-circuit debugging.
Through this debug interface, it is possible to erase or program the entire flash memory, control which oscillators
are enabled, stop and start execution of the user program, execute instructions on the 8051 core, set code
breakpoints, and single-step through instructions in the code. Using these techniques, it is possible to perform
in-circuit debugging and external flash programming elegantly.
The I/O controller is responsible for all general-purpose I/O pins. The CPU can configure whether peripheral
modules control certain pins or whether they are under software control, and if so, whether each pin is configured
as an input or output and if a pullup or pulldown resistor in the pad is connected. Each peripheral that connects
to the I/O pins can choose between two different I/O pin locations to ensure flexibility in various applications.
The sleep timer is an ultralow-power timer that can either use an external 32.768-kHz crystal oscillator or an
internal 32.753-kHz RC oscillator. The sleep timer runs continuously in all operating modes except power mode
3. Typical applications of this timer are as a real-time counter or as a wake-up timer to get out of power modes 1
or 2.
A built-in watchdog timer allows the CC2540 to reset itself if the firmware hangs. When enabled by software,
the watchdog timer must be cleared periodically; otherwise, it resets the device when it times out.

Timer 1 is a 16-bit timer with timer/counter/PWM functionality. It has a programmable prescaler, a 16-bit period
value, and five individually programmable counter/capture channels, each with a 16-bit compare value. Each of
the counter/capture channels can be used as a PWM output or to capture the timing of edges on input signals. It
can also be configured in IR generation mode, where it counts timer 3 periods and the output is ANDed with the
output of timer 3 to generate modulated consumer IR signals with minimal CPU interaction.
Timer 2 is a 40-bit timer used by the Bluetooth low energy stack. It has a 16-bit counter with a configurable timer
period and a 24-bit overflow counter that can be used to keep track of the number of periods that have
transpired. A 40-bit capture register is also used to record the exact time at which a start-of-frame delimiter is
received/transmitted or the exact time at which transmission ends. There are two 16-bit timer-compare registers
and two 24-bit overflow-compare registers that can be used to give exact timing for start of RX or TX to the radio
or general interrupts.
Timer 3 and timer 4 are 8-bit timers with timer/counter/PWM functionality. They have a programmable prescaler,
an 8-bit period value, and one programmable counter channel with an 8-bit compare value. Each of the counter
channels can be used as PWM output.
USART 0 and USART 1 are each configurable as either an SPI master/slave or a UART. They provide double
buffering on both RX and TX and hardware flow control and are thus well suited to high-throughput full-duplex
applications. Each USART has its own high-precision baud-rate generator, thus leaving the ordinary timers free
for other uses. When configured as SPI slaves, the USARTs sample the input signal using SCK directly instead
of using some oversampling scheme, and are thus well-suited for high data rates.
The AES encryption/decryption core allows the user to encrypt and decrypt data using the AES algorithm with
128-bit keys. The AES core also supports ECB, CBC, CFB, OFB, CTR, and CBC-MAC, as well as hardware
support for CCM.
The ADC supports 7 to 12 bits of resolution with a corresponding range of bandwidths from 30-kHz to 4-kHz,
respectively. DC and audio conversions with up to eight input channels (I/O controller pins) are possible. The
inputs can be selected as single-ended or differential. The reference voltage can be internal, AVDD, or a
single-ended or differential external signal. The ADC also has a temperature-sensor input channel. The ADC can
automate the process of periodic sampling or conversion over a sequence of channels.
The operational amplifier is intended to provide front-end buffering and gain for the ADC. Both inputs as well as
the output are available on pins, so the feedback network is fully customizable. A chopper-stabilized mode is
available for applications that need good accuracy with high gain.
The ultralow-power analog comparator enables applications to wake up from PM2 or PM3 based on an analog
signal. Both inputs are brought out to pins; the reference voltage must be provided externally. The comparator
output is connected to the I/O controller interrupt detector and can be treated by the MCU as a regular I/O pin
interrupt.

When using an unbalanced antenna such as a monopole, a balun should be used to optimize performance. The
balun can be implemented using low-cost discrete inductors and capacitors. The recommended balun shown
consists of C262, L261, C252, and L252.
Crystal
An external 32-MHz crystal, XTAL1, with two loading capacitors (C221 and C231) is used for the 32-MHz crystal
oscillator. See 32-MHz CRYSTAL OSCILLATOR for details. The load capacitance seen by the 32-MHz crystal is
given by:

XTAL2 is an optional 32.768-kHz crystal, with two loading capacitors (C321 and C331) used for the 32.768-kHz
crystal oscillator. The 32.768-kHz crystal oscillator is used in applications where both very low sleep-current
consumption and accurate wake-up times are needed. The load capacitance seen by the 32.768-kHz crystal is
given by:

A series resistor may be used to comply with the ESR requirement.
On-Chip 1.8-V Voltage Regulator Decoupling
The 1.8-V on-chip voltage regulator supplies the 1.8-V digital logic. This regulator requires a decoupling capacitor
(C401) for stable operation.
Power-Supply Decoupling and Filtering
Proper power-supply decoupling must be used for optimum performance. The placement and size of the
decoupling capacitors and the power supply filtering are very important to achieve the best performance in an
application. TI provides a compact reference design that should be followed very closely.
