PIC16F1779-E/P - 28KB Flash 8-bit MCU, 32MHz, 40-PDIP | Microchip
The Microchip Technology PIC16F1779-E/P is an 8-bit PIC RISC microcontroller with 28KB Flash program memory, 2KB RAM, and 32MHz CPU speed, housed in a 40-pin PDIP (0.600", 15.24mm) through-hole package. Operating from 2.5V to 5.5V, the device integrates 28KB Flash (16K x 14 words), a high-performance 32MHz internal oscillator, 10-bit ADC, 10-bit DAC, high-speed comparators, operational amplifiers, zero-cross detect (ZCD), programmable ramp generator (PRG), 100mA high-current I/Os, peripheral pin select (PPS), 10/16-bit PWMs, and SPI/I2C/EUSART communication peripherals.
What is a PIC microcontroller? A PIC (Peripheral Interface Controller) microcontroller is a small, low-cost, programmable computer on a single integrated circuit that combines a CPU, RAM, non-volatile program memory (Flash), and configurable peripherals (ADC, PWM, timers, communication interfaces) on one die. PIC microcontrollers belong to the broader microcontroller family in the semiconductor hierarchy: microcontroller -> embedded processor -> integrated circuit -> semiconductor. The PIC16F1779 falls within Microchip's PIC16F mid-range 8-bit family optimized for intelligent analog and digital peripheral integration.
Key features of the PIC16F1779-E/P include 28KB self-programmable Flash, 2KB SRAM, 256 bytes of EEPROM, 36 I/O pins capable of sourcing/sinking 100mA for direct LED or power MOSFET drive, four 16-bit timers, four 10-bit PWMs, four 16-bit PWMs, and a peripheral pin select (PPS) module that remaps digital peripherals to any I/O pin for layout flexibility. The integrated op-amps, comparators, DAC, and ramp generator form a closed-loop analog control engine suitable for lighting ballast, switched-mode power supply (SMPS), and motor control applications.
The PIC16F1779 utilizes a Harvard RISC architecture with a 14-bit instruction word and a single-cycle instruction execution at 32MHz (8 MIPS). The device includes Core Independent Peripherals (CIPs) such as the Complementary Waveform Generator (CWG), Numerically Controlled Oscillator (NCO), and Configurable Logic Cells (CLC) that operate without CPU intervention, freeing the core for supervisory tasks and reducing firmware complexity.
Typical applications include LED lighting drivers with dimming, AC-DC and DC-DC switched-mode power supplies with PFC, battery chargers, BLDC and stepper motor control, wireless charging, and general-purpose embedded control. The PIC16F1779's integrated op-amps, comparators, and ramp generator particularly suit digital power conversion and lighting ballast designs where discrete analog control is normally required.
When designing with this device, configure the configuration bits for the desired oscillator mode (INTOSC is typical for 32MHz operation) and unlock PPS sequencing for remapping. The high-current I/O pins can directly drive power MOSFETs or LED strings, simplifying BOM and PCB area.
