Housed in a 28-pin SPDIP package, this device is designed for embedded applications requiring a combination of processing capability, energy efficiency, and peripheral integration.
Core Architecture and Performance
At its heart lies an 8-bit PIC16F87xA core, capable of operating at speeds up to 20 MHz, achieving a instruction throughput of 5 MIPS. The microcontroller features 8K words of Flash program memory, 368 bytes of RAM, and 256 bytes of EEPROM data memory, providing ample space for both code and non-volatile data storage. Its Harvard architecture separates program and data memory, enabling concurrent access and higher overall performance.
Low-Power Characteristics
A defining trait of the PIC16LF876A is its low-power operation. Designed for battery-powered and portable applications, it supports a wide operating voltage range from 2.0V to 5.5V. Multiple oscillator options, including the power-saving LP, XT, and INTRC modes, allow designers to fine-tune the balance between performance and power consumption. The device also features a SLEEP mode that drastically reduces power draw to nanoampere levels, making it ideal for applications spending significant time in a standby state.
