PIC16F1764T-I/ST - 8-Bit MCU, 7KB Flash, 32MHz, 14-TSSOP | Microchip
The Microchip Technology PIC16F1764T-I/ST is an 8-bit PIC16 microcontroller from the PIC16F176X family, integrating 7KB (4K x 14 words) of Flash program memory, 512 bytes of RAM, and a 32 MHz internal core clock in a 14-pin TSSOP surface-mount package. The device targets intelligent analog applications, pairing a 10-bit A/D converter with 10-bit DAC, operational amplifiers, zero-cross detect (ZCD) hardware, configurable logic cells (CLC), and high-current (100 mA) I/O pins to support a wide range of mixed-signal designs.
An 8-bit microcontroller (MCU) is a programmable processor built around an 8-bit data bus, optimized for low power, deterministic real-time control, and high peripheral integration at low cost. The PIC16F176X sits in the hierarchy: microcontroller -> embedded MCU -> 8-bit MCU -> PIC16 family -> PIC16F176X sub-family, with the PIC® XLP™ (eXtreme Low Power) technology platform enabling deep sleep currents in the nanoamp range. These parts typically serve as the supervisory brain for power conversion, lighting, sensing, and motor/valve control where analog precision and timing accuracy matter more than raw throughput.
Key features include 7KB Flash, 512 bytes SRAM, 256 bytes EEPROM, 10-bit ADC with computation (ADC2), a 10-bit DAC, two op amps, three 16-bit PWMs with complementary outputs and programmable dead-band, zero-cross detect, three configurable logic cells (CLC), peripheral pin select (PPS), high-current I/O capable of 100 mA source/sink, and an internal 32 MHz oscillator. The integrated op amps, ZCD, CLC, and high-current I/O distinguish the 176X family from generic 8-bit MCUs and remove the need for several external analog components.
The architecture uses a Harvard RISC core with 49 instructions and a 14-bit instruction word, executed in two instruction cycles at 32 MHz (8 MIPS). On-chip peripherals share the data bus via a peripheral pin select (PPS) remap scheme that lets designers move digital functions to almost any I/O pin, simplifying PCB routing in tight 14-pin footprints.
Typical applications include LED lighting controllers and drivers, TRIAC/SSR dimming with ZCD, AC power monitoring with op-amp signal conditioning, small BLDC or brushed-DC motor control loops using the 16-bit PWMs, battery chargers, smart sensors with on-chip op-amp front-ends, IoT edge nodes, and white-goods / appliance user interfaces. The high-current I/O lets the MCU directly drive relays, triacs, and LED strings without external drivers.
When designing with this part, ensure that the maximum high-current I/O sink/source budget (per pin and per package) is respected: each pin is rated up to 100 mA but the total package dissipation must stay within thermal limits. Place a 0.1 µF decoupling capacitor on VDD as close as possible to the pin and add a bulk cap of at least 1 µF, while following Microchip AN(s) for oscillator layout and PPS remapping.
