Microchip PIC16LF877-04/PT 8-Bit Microcontroller Datasheet and Application Overview
The PIC16LF877-04/PT is a high-performance, low-power 8-bit microcontroller from Microchip Technology, built on the robust RISC architecture of the PICmicro family. This powerful yet energy-efficient device is housed in a 44-lead TQFP (Thin Quad Flat Pack) package, making it suitable for space-constrained applications. Operating at a maximum frequency of 4 MHz with a wide voltage range of 2.0V to 5.5V, it is expressly designed for battery-powered and portable devices where power conservation is critical.
At its core, 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 complex code and non-volatile data storage. Its rich peripheral set is a significant advantage, including:
A 10-bit Analog-to-Digital Converter (ADC) with up to 8 channels.
Two analog comparators.
Multiple communication interfaces: USART (Universal Synchronous Asynchronous Receiver Transmitter), SPI (Serial Peripheral Interface), and I²C (Inter-Integrated Circuit).
Two 8-bit timers and one 16-bit timer with Capture/Compare/PWM modules.
A watchdog timer and a brown-out reset (BOR) circuit for enhanced reliability.
A key strength of the PIC16LF877 lies in its low-power capabilities. The "LF" designation indicates its operation in the lower voltage spectrum, enabling it to consume minimal current in active, sleep, and watchdog timer modes. This makes it an ideal choice for applications that must run for extended periods on a single battery.
