PIC16F886-I/SP
PIC16F886-I/SP - 20MHz 8-Bit Flash MCU | Microchip Technology
The Microchip Technology PIC16F886-I/SP is an 8-bit CMOS Flash microcontroller with a 20 MHz operating speed, 14 KB of program Flash, 368 bytes of RAM, and 256 bytes of EEPROM in a 28-pin SPDIP package. It is designed for compact embedded-control products that need analog measurement, programmable digital control, and serial connectivity without an external program-memory device.
A microcontroller is a programmable system-on-chip that integrates a CPU, Flash program memory, data memory, timers, analog converters, communication peripherals, and I/O pins. Within the product hierarchy, the PIC16F886 is a PIC16 8-bit MCU, a CMOS embedded-control semiconductor commonly used in industrial controllers, instrumentation, consumer products, and compact automation systems. Its 35 single-word instructions simplify firmware development while retaining self-programming and in-circuit debugging support.
The PIC16F886-I/SP provides 11 channels of 10-bit analog-to-digital conversion, two comparators, one conventional capture/compare/PWM module, and one enhanced capture/compare/PWM module. These resources allow a single device to acquire analog sensor data, perform closed-loop control, generate PWM outputs, and communicate with external peripherals. The manufacturer also identifies 24 I/O pins in the device family, making the part suitable for mixed analog and digital control boards.
Communication features include I2C, SPI, and UART/USART, as identified in the product listing, allowing the MCU to interface with sensors, displays, transceivers, data converters, and other embedded systems. The 368-byte RAM supports working variables and stack operations, while 256 bytes of EEPROM preserves calibration data, configuration values, counters, or serial numbers when the supply is removed. Self-programming supports field updates in applications where firmware changes must be retained in Flash.
Typical applications include temperature controllers, motor and valve controllers, panel meters, programmable logic controllers, sensor nodes, power-supply controllers, and compact industrial automation equipment. The 28-pin through-hole package also makes the MCU practical for prototypes, education systems, and legacy control boards that require a socketed DIP rather than a fine-pitch surface-mount package.
For reliable designs, verify every pin function against the manufacturer pin-description table and preserve the required MCLR and decoupling connections. Use the device's application guidance to configure oscillator, analog-reference, comparator, communications, and brown-out functions. This page combines the device specifications, package information, drop-in alternatives, comparison guidance, and practical design notes needed for component selection and PCB planning.
