Key Features
- Operates from 2 V minimum supply at 4 MHz, ideal for 2-cell AA battery-powered embedded designs
- 7 KB self-programmable Flash plus 256 bytes EEPROM for non-volatile parameter storage without external memory
- USART, SPI master/slave, and I2C in an 18-pin PDIP package, enabling direct breadboard development and prototyping
Applications
The PIC16LF87-I/P is used in low-power embedded control applications such as remote sensors, battery-operated data loggers, and home automation nodes where the 2 V minimum supply enables direct operation from two AA alkaline cells. Its USART and SPI interfaces support RS-232 adapters and SD card modules for simple data recording systems. The 18-pin PDIP package is popular in educational projects and rapid prototyping where solderless breadboards are used.

Frequently Asked Questions
At what clock frequencies can PIC16LF87-I/P operate when powered from a 2 V battery supply?
The PIC16LF87-I/P is specified to operate at up to 4 MHz when the supply voltage is as low as 2 V, which corresponds to two partially discharged AA alkaline cells. At a full 5 V supply, the device runs at up to 20 MHz. This clock-voltage relationship allows firmware designers to implement dynamic frequency scaling to extend battery life in data-logger and sensor applications.
Does PIC16LF87-I/P include an ADC, and what sensor interface options are available?
The PIC16LF87-I/P does not include an on-chip ADC, distinguishing it from the PIC16LF877 family. Analog inputs must be digitized externally, for example via an MCP3201 SPI ADC over the integrated SPI port. The device does provide 13 digital I/O pins, USART for RS-232 communication, and I2C for sensors such as temperature ICs and real-time clocks, covering a wide range of non-ADC sensor interfacing needs.
How much non-volatile data storage does PIC16LF87-I/P offer for configuration parameters?
The PIC16LF87-I/P provides 256 bytes of on-chip EEPROM data memory rated for 1,000,000 write/erase cycles and 40-year data retention. This is sufficient to store calibration constants, device addresses, error logs, and user configuration bytes without any external EEPROM IC. The EEPROM is byte-addressable and accessible from firmware via built-in read/write control registers.
When would PIC16LF87-I/P be chosen over PIC16F87 for a low-voltage battery design?
The PIC16LF87-I/P (LF = Low-voltage Flash) is the preferred choice when the design must operate from supplies below 4.5 V, such as 2-cell AA or 3 V coin-cell batteries, because it is specified down to 2 V at 4 MHz. The standard PIC16F87 requires a minimum 4.5 V supply for guaranteed operation. Both devices are pin-compatible in the 18-pin PDIP package, making the LF variant a drop-in replacement when lower voltage operation is needed.
