PIC16F767T-I/SO - 8-Bit 20MHz 14KB FLASH MCU 28-SOIC | Microchip
The Microchip Technology PIC16F767T-I/SO is a 8-bit CMOS FLASH-based PIC16F microcontroller running at up to 20 MHz instruction execution (200 ns instruction cycle), delivering 14 KB (8K x 14 words) of on-chip program memory, 368 bytes of RAM, and 256 bytes of EEPROM, all packaged in a 28-pin SOIC (7.50 mm width). It integrates a 14-channel 10-bit Analog-to-Digital Converter (ADC), two analog comparators, a USART, MSSP (SPI/I2C), and multiple timer modules, making it a highly integrated MCU for mixed-signal embedded designs.
A microcontroller is a single-chip computer that integrates a CPU core, non-volatile program memory, working RAM, data EEPROM, and a rich set of peripheral interfaces (ADC, timers, communication ports, GPIO) on a single die. Within the broader system hierarchy, the PIC16F767 sits between 8-bit MCUs and 16-bit/32-bit controllers; it is a member of the PIC16F mid-range family, optimized for low power, deterministic interrupt response, and small-footprint designs that do not require 32-bit throughput. The PIC16F767 architecture is object-code compatible with the earlier PIC16C5X, PIC12C and PIC14000 devices, easing migration for legacy designs.
Key features include nanoWatt technology with multiple power-managed modes (Run, Idle, Sleep), an internal 8 MHz oscillator, two PWM modules, a master synchronous serial port (MSSP) supporting both SPI and I2C, an enhanced USART with auto-baud detection, a 10-bit ADC with up to 14 channels, a parallel slave port, and a nanoWatt reference clock output of 32 kHz. With 25 mA source/sink per I/O, the device can directly drive LEDs and small relays, reducing BOM cost in HMI and appliance designs.
The PIC16F767 uses a RISC-like Harvard architecture with only 35 single-word instructions, allowing most instructions to execute in a single 200 ns cycle. Program memory is FLASH with self-programming support and ICD (in-circuit debugger) capability, so firmware can be updated and debugged in-circuit via two debug pins. Its wide 2.0 V to 5.5 V operating range makes it compatible with both 3.3 V and 5 V system rails commonly found in industrial and consumer products.
Typical applications include sensor signal conditioning with on-chip ADC, industrial control panels, low-cost 8-bit general-purpose embedded control, motor drive interfaces with PWM, lighting controllers, and home appliance control boards. The 28-SOIC package is the most popular footprint for hand-soldered prototypes and small-batch industrial assemblies.
When designing with this part, ensure decoupling capacitors of 100 nF and 10 uF are placed close to VDD/VSS pins, and that the MCLR pin is pulled high through a 10 kohm resistor unless an external reset controller is used. The ICD pins must be reserved for in-circuit debugging, and unused I/O pins should be configured as outputs low to minimize power draw in sleep mode.
