PIC16F886T-I/SS
PIC16F886T-I/SS - 14KB Flash 20MHz 8-bit MCU 28-SSOP | Microchip
The Microchip Technology PIC16F886T-I/SS is an 8-bit CMOS flash-based microcontroller in the mid-range PIC16F family, delivering 20 MHz CPU speed with 14 KB (8K x 14) of program Flash, 368 bytes of RAM, and 256 bytes of EEPROM in a 28-pin SSOP package. The 'T' suffix indicates Tape & Reel packaging and the 'I' grade specifies the industrial -40C to +85C operating temperature range, while 'SS' designates the 28-SSOP form factor. The device integrates 11 channels of 10-bit Analog-to-Digital conversion, 2 comparators, 1 capture/compare/PWM module, and a 25-pin I/O count via the Enhanced PIC16 mid-range core with only 35 single-word instructions.
What is a mid-range 8-bit flash microcontroller? A microcontroller (MCU) is a single-chip computer containing a CPU, non-volatile program memory, volatile data memory, peripherals, and I/O on one die. The PIC16F mid-range family uses Microchip's Reduced Instruction Set Computing (RISC) Harvard architecture with separate program and data buses, single-cycle instructions at 20 MHz (200 ns), and nanoWatt power management for low-power operation. Within the broader semiconductor taxonomy, the device sits as: MCU -> 8-bit MCU -> flash MCU -> mid-range PIC16F.
Key differentiating features include nanoWatt technology for sleep currents below 1 uA typical, an ICD (In-Circuit Debug) interface for non-intrusive programming, self-programming capability for bootloader-style firmware updates, and a hardware USART for asynchronous serial communication. The 14 KB Flash memory supports at least 10,000 erase/write cycles per Microchip's endurance specifications, while the 256-byte EEPROM provides at least 1,000,000 erase/write cycles for non-volatile parameter storage.
The PIC16F886 uses an enhanced Harvard architecture with a 14-bit instruction word, 8-bit data bus, and a pipelined fetch/decode/execute cycle. The device includes a Phase-Locked Loop (PLL) on selectable variants, internal 8 MHz and 31 kHz oscillators, and a programmable brown-out reset. The peripheral set covers timers (Timer0, Timer1, Timer2), MSSP (Master Synchronous Serial Port) for SPI and I2C, an addressable Universal Synchronous/Asynchronous Receiver/Transmitter (USART), and an enhanced CCP module for PWM and capture.
Typical applications include industrial control panels, sensor signal conditioning nodes, low-power remote battery-operated sensor transmitters, white-goods and appliance controllers, automotive aftermarket accessories, lighting controls, and consumer peripherals. The combination of 14 KB Flash, 28 pins, and nanoWatt technology makes this part a popular general-purpose MCU for embedded products that need more code space than a PIC16F84 or PIC12F series can provide.
When designing with this part, pay close attention to the I/O pin sharing between analog channels, digital peripherals, and ICSP programming pins - misconfiguring analog pins as digital outputs is a common pitfall. The ICD pins are shared with RB6/RB7, so leave those unconstrained in the schematic for in-circuit debugging.
