PIC16F1579T-I/GZ - 8-Bit 32MHz 14KB Flash MCU | Microchip
The Microchip Technology PIC16F1579T-I/GZ is an 8-bit PIC microcontroller in a 20-pin UQFN (4x4 mm) package with 14KB Flash, 1KB RAM, four 16-bit PWMs with independent timers, a 10-bit ADC, and a 32MHz internal oscillator. The trailing "/GZ" suffix denotes the 20-pin UQFN package, the "T" suffix denotes tape-and-reel packaging, and the "I" suffix denotes the industrial -40C to +85C operating temperature range.
A PIC microcontroller is a RISC (Reduced Instruction Set Computer) based 8-bit MCU from Microchip's PIC16 family. PIC MCUs integrate CPU, Flash program memory, RAM data memory, EEPROM, peripherals (ADC, PWM, timers, communication), and a programmable I/O structure onto a single die. Within the broader taxonomy, PIC16F1579 belongs to the PIC16F157X family, which extends the mid-range PIC16 architecture by combining 16-bit PWM resolution with analog peripherals for high-resolution mixed-signal applications such as LED lighting and motor control.
Key features include 14KB (8K x 14 words) self-programmable Flash program memory, 1KB RAM, four 16-bit PWMs with independent timers for fine-grained duty control, a 10-bit ADC with multiple channels, configurable logic cells (CLC), complementary waveform generator (CWG), and an internal 32MHz oscillator. The device also supports up to 18 I/O pins, multiple serial interfaces, and 5-bit DAC for analog signal generation.
Architecturally, the PIC16F1579 uses Microchip's enhanced mid-range 8-bit core with a hardware 14-bit instruction set, 16-level hardware stack, and a 32kHz to 32MHz internal oscillator block with PLL. The four 16-bit PWMs use independent Timer2/4/6 modules for phase-shifted or synchronized outputs, while the 10-bit ADC operates up to 100 ksps. Configurable Logic Cells provide user-defined combinational and sequential logic gates without external components.
Typical applications include high-resolution LED lighting drivers (RGBW and tunable white), DC-DC converters with digital control loops, BLDC and stepper motor commutation, digital power supplies, battery chargers with mixed-signal monitoring, and general-purpose mixed-signal embedded control. The 20-pin UQFN (4x4 mm) package suits compact PCB designs where board area is at a premium.
When designing with the PIC16F1579T-I/GZ, ensure the exposed thermal pad on the UQFN package is soldered to the PCB ground plane for thermal and electrical performance. The device operates from 2.3V to 5.5V VDD; verify that VDD rise-time meets datasheet specification for proper brown-out reset behavior. For noise-sensitive analog applications, place the VDD/VSS decoupling network within 3 mm of the IC pins.
