GENERAL DESCRIPTION
The Enhanced PIC16LV5X from Microchip Technology
is a family of low-cost, high performance, 8-bit, fully
static, EPROM-based CMOS microcontrollers. This
family is pin and software compatible with the
PIC16LV5X family of devices in a new enhanced
process technology. It employs a RISC architecture
with only 33 single word/single cycle instructions. All
instructions are single cycle (2 µs) except for program
branches which take two cycles. The Enhanced
PIC16LV5X delivers performance an order of magni-
tude higher than its competitors in the same price cat-
egory. The 12-bit wide instructions are highly
symmetrical resulting in 2:1 code compression over
other 8-bit microcontrollers in its class. The easy to use
and easy to remember instruction set reduces
development time significantly.
The Enhanced PIC16LV5X series fits perfectly in appli-
cations such as low-power remote transmitters/receiv-
ers and pointing devices. The EPROM technology
makes customizing application programs (transmitter
codes, receiver frequencies, etc.) extremely fast and
convenient. The small footprint packages, for through
hole or surface mounting, make this microcontroller
series perfect for applications with space limitations.
Low-cost, low-power, high performance, ease of use
and I/O flexibility make the Enhanced PIC16LV5X
series very versatile even in areas where no microcon-
troller use has been considered before (e.g., timer
functions, replacement of “glue” logic in larger systems,
coprocessor applications).
The Enhanced PIC16LV5X products are equipped with
special features that reduce system cost and power
requirements. The Power-On Reset (POR) and Device
Reset Timer (DRT) eliminate the need for external
reset circuitry. There are three oscillator configurations
to choose from, including the power-saving LP (Low
Power) oscillator and cost saving RC oscillator. Power
saving SLEEP mode, Watchdog Timer and code
protection features improve system cost, power and
reliability.
The UV erasable CERDIP packaged versions are ideal
for code development, while the cost-effective
One-Time-Programmable (OTP) versions are suitable
for production in any volume. The customer can take
full advantage of Microchip’s price leadership in OTP
microcontrollers while benefiting from the OTP’s
flexibility.
The Enhanced PIC16LV5X products are supported by
a full-featured macro assembler, a software simulator,
an in-circuit emulator, a ‘C’ compiler, fuzzy logic sup-
port tools, a low-cost development programmer, and a
full featured programmer. All the tools are supported on
IBM PC and compatible machines.

ENHANCED PIC16LV5X
DEVICE VARIETIES
A variety of frequency ranges and packaging options
are available. Depending on application and
production requirements, the proper device option can
be selected using the information in this section. When
placing orders, please use the Enhanced PIC16LV5X
Product Identification System at the back of this data
sheet to specify the correct part number.
Microchip offers a QTP Programming Service for
factory production orders. This service is made
available for users who choose not to program a
medium to high quantity of units and whose code
patterns have stabilized. The devices are identical to
the OTP devices but with all EPROM locations and
configuration bit options already programmed by the
factory. Certain code and prototype verification
procedures apply before production shipments are
available. Please contact your Microchip Technology
sales office for more details.
For the Enhanced PIC16LV5X family of devices, there
is one device type, as indicated in the device number:
1. LV, as in PIC16LV54A. These devices have
EPROM program memory and operate over the
standard voltage range of 2.0 to 3.8 volts.

2.1
UV Erasable Devices
(SQTPSM) Devices
The UV erasable versions, offered in CERDIP
packages, are optimal for prototype development and
pilot programs
Microchip offers the unique programming service
where a few user-defined locations in each device are
programmed with different serial numbers. The serial
numbers may be random, pseudo-random or
sequential.
UV erasable devices can be programmed for any of
the four oscillator configurations. Microchip's
PICSTART and PRO MATE programmers both
support programming of the Enhanced PIC16LV5X.
Third party programmers also are available; refer to
the Third Party Guide for a list of sources.
Serial programming allows each device to have a
unique number which can serve as an entry code,
password or ID number.
2.2
One-Time-Programmable (OTP)
Devices
The availability of OTP devices is especially useful for
customers expecting frequent code changes and
updates.
The OTP devices, packaged in plastic packages,
permit the user to program them once. In addition to
the program memory, the configuration bits must be
programmed.

Note 1: Power dissipation is calculated as follows: Pdis = VDD x {IDD - ∑ IOH} + ∑ {(VDD-VOH) x IOH} + ∑(VOL x IOL)
Note 2: Voltage spikes below VSS at the MCLR pin, inducing currents greater than 80mA, may cause latch-up. Thus,
a series resistor of 50-100Ω should be used when applying a “low” level to the MCLR pin rather than pulling
this pin directly to VSS
†
NOTICE: Stresses above those listed under "Maximum Ratings" may cause permanent damage to the device.
This is a stress rating only and functional operation of the device at those or any other conditions above those
indicated in the operation listings of this specification is not implied. Exposure to maximum rating conditions for
extended periods may affect device reliability.

* These parameters are characterized but not tested.
Note 1: Data in the Typical (“Typ”) column is based on characterization results at 25°C. This data is for design guid-
ance only and is not tested.
2: This is the limit to which VDD can be lowered in SLEEP mode without losing RAM data.
3: The supply current is mainly a function of the operating voltage and frequency. Other factors such as bus
loading, oscillator type, bus rate, internal code execution pattern, and temperature also have an impact on
the current consumption.
a) The test conditions for all IDD measurements in active operation mode are:
OSC1 = external square wave, from rail-to-rail; all I/O pins tristated, pulled to
Vss, T0CKI = VDD, MCLR = VDD; WDT enabled/disabled as specified.
b) For standby current measurements, the conditions are the same, except that
the device is in SLEEP mode.
4: Does not include current through Rext. The current through the resistor can be estimated by the
formula: IR = VDD/2Rext (mA) with Rext in kΩ.
5: The power down current in SLEEP mode does not depend on the oscillator type. Power down current is
measured with the part in SLEEP mode, with all I/O pins in hi-impedance state and tied to VDD and VSS.
6: The oscillator start-up time can be as much as 8 seconds for XT and LP oscillator selection, if the SLEEP
mode is entered or during initial power-up.

Note 1: Data in the Typical (“Typ”) column is based on characterization results at 25°C. This data is for design guidance
only and is not tested.
2: The leakage current on the MCLR/VPP pin is strongly dependent on the applied voltage level. The specified
levels represent normal operating conditions. Higher leakage current may be measured at different input
voltage.
3: Negative current is defined as coming out of the pin.
4: For the RC option, the OSC1/CLKIN pin is a Schmitt Trigger input. It is not recommended that the
PIC16LV5X be driven with external clock in RC mode.

These parameters are characterized but not tested.
Note 1: Data in the Typical (“Typ”) column is at 3.8V, 25˚C unless otherwise stated. These parameters are for design guidance
only and are not tested.
2: All specified values are based on characterization data for that particular oscillator type under standard operating condi-
tions with the device executing code. Exceeding these specified limits may result in an unstable oscillator operation and/or
higher than expected current consumption.
When an external clock input is used, the “max” cycle time limit is “DC” (no clock) for all devices.
3: Instruction cycle period (TCY) equals four times the input oscillator time base period.

CONNECTING TO MICROCHIP BBS
Trademarks:
Connect worldwide to the Microchip BBS using the
CompuServe communications network. In most
cases a local call is your only expense. The Microchip
BBS connection does not use CompuServe
membership services, therefore, you do not need
CompuServe membership to join Microchip's BBS.
The Microchip logo and name are registered
trademarks of Microchip Technology Inc. PIC is a
registered trademark of Microchip Technology
Incorporated in the U.S.A.
SQTP is a service mark of Microchip
Technology Inc.
There is no charge for connecting to the BBS, except
toll charge to CompuServe access number, where
applicable. You do not need to be a CompuServe
member to take advantage of this connection (you
never actually log in to CompuServe).
All other trademarks mentioned herein are the
property of their respective companies.
The procedure to connect will vary slightly from
country to country. Please check with your local
CompuServe agent for details if you have a problem.
CompuServe service allows multiple users at baud
rates up to 14,400 bps.
The following connect procedure applies in most
locations:
1. Set your modem to 8-bit, No parity, and One
stop (8N1). This is not the normal CompuServe
setting which is 7E1.
2. Dial your local CompuServe access number.
3. Depress <ENTER > and a garbage string will
appear because CompuServe is expecting a
7E1 setting.
4. Type +, depress <ENTER > and Host Name:
will appear.
5. Type MCHIPBBS, depress < ENTER > and
you will be connected to the Microchip BBS.
In the United States, to find CompuServe's phone
number closest to you, set your modem to 7E1 and
dial (800) 848-4480 for 300-2400 baud or
(800) 331-7166 for 9600-14400 baud connection. After
the system responds with Host Name:
Type, NETWORK, depress < ENTER > and follow
CompuServe's directions.
For voice information (or calling from overseas), you
may call (614) 723-1550 for your local CompuServe
number.
