What are the key features of PIC16C745-I/SO?
- Integrated USB 1.1 full-speed peripheral enables direct USB device connectivity without an external USB bridge chip
- 8-bit PIC16 CPU running at up to 24 MHz balances performance and low power in cost-sensitive designs
- Onboard ADC supports analog sensor acquisition alongside USB communication in a single-chip solution
- 28-pin SOIC package with 0.3 inch body width suits standard through-hole-friendly PCB tooling
What is PIC16C745-I/SO used for?
PIC16C745-I/SO is designed for USB HID and CDC device applications such as custom keyboards, joysticks, and USB-to-serial adapters where a low-cost 8-bit microcontroller with native USB 1.1 eliminates external USB ICs. Running at 24 MHz from a 5 V supply, it handles real-time sensor polling through its ADC while simultaneously maintaining the USB 12 Mbps full-speed enumeration and data transfer. Hobbyist and low-volume industrial USB data-logger designs benefit from its combination of a familiar PIC16 instruction set, a SOIC package for easy hand-soldering, and broad Microchip development tool support.

Frequently Asked Questions
What is the maximum clock frequency of PIC16C745-I/SO and how does it compare to other PIC16 parts?
PIC16C745-I/SO operates at up to 24 MHz, which translates to 6 MIPS execution throughput under the 4-clock-per-instruction PIC16 architecture. This is faster than the 20 MHz variants of the PIC16F628A but is matched by other USB-capable PIC16C parts, providing enough headroom to run USB firmware stacks while still servicing 8 ADC channels at hundreds of samples per second.
Does PIC16C745-I/SO support USB and if so what USB speed does it implement?
Yes, PIC16C745-I/SO includes an integrated USB 1.1 full-speed peripheral operating at 12 Mbps. This allows the chip to act as a USB device without any external USB bridge or transceiver IC, supporting standard descriptor classes such as HID for human-interface devices and vendor-specific bulk transfers for custom data-acquisition designs running from a 5 V USB bus.
What supply voltage does PIC16C745-I/SO require and is it compatible with USB bus power?
PIC16C745-I/SO operates from 4 V to 5.5 V, making it directly compatible with the 5 V VBUS supply delivered by a standard USB host port. This eliminates the need for a voltage regulator in bus-powered designs, simplifying BOM and reducing cost in applications like USB sensors, HID devices, and low-speed data loggers drawing under 100 mA.
How many I/O pins and ADC channels does PIC16C745-I/SO offer for peripheral interfacing?
The 28-pin SOIC package provides up to 22 general-purpose I/O pins, and the integrated ADC supports multiple analog input channels for sensor interfacing. With 8 ADC channels available alongside the USB peripheral, the device can simultaneously monitor temperature, light, or pressure sensors and stream sampled data at up to 24 MHz clock rate to a USB host without external analog multiplexers.
