Microchip PIC17C756A-16/L: An 8-Bit CMOS Powerhouse with OTP and Advanced Peripherals

The Microchip PIC17C756A-16/L represents a significant member of the robust PIC17C family, engineered for complex embedded control applications that demand high performance and a rich set of integrated features. As an 8-bit CMOS microcontroller with One-Time Programmable (OTP) memory, it offers a compelling solution for mid-to-high-volume production runs where firmware stability is paramount and last-minute code changes are not anticipated.

At its core, the device operates at a clock speed of up to 16 MHz, enabling it to execute most instructions in a swift 250 ns cycle time. This computational power is driven by an enhanced Harvard architecture core, which separates program and data memory for improved throughput. The microcontroller is equipped with 16 KB of OTP program memory, providing a reliable and secure medium for code storage. This is complemented by 454 bytes of RAM, ensuring ample space for data manipulation during operation.

The "Advanced Peripherals" in its title are not an overstatement. The PIC17C756A-16/L is a peripheral-rich microcontroller designed to interface with the outside world with minimal external components. Key features include:

A sophisticated 10-bit Analog-to-Digital Converter (ADC) with up to 12 input channels, essential for precision sensor data acquisition.

Two powerful PWM (Pulse Width Modulation) modules, which are critical for controlling motors, LEDs, and power supplies.

Multiple communication interfaces, including a USART (Universal Synchronous Asynchronous Receiver Transmitter) for RS-232/485 communication and an SPI (Serial Peripheral Interface) module for high-speed communication with peripheral ICs.

Five 8-bit parallel ports, offering extensive digital I/O capabilities for interfacing with buttons, displays, and other digital signals.

Housed in a 68-pin PLCC package, the PIC17C756A-16/L is built for durability and performance in industrial environments. Its CMOS technology ensures low power consumption, making it suitable for a wide range of applications, from sophisticated automotive systems and industrial automation to advanced consumer electronics and medical devices.

ICGOODFIND: The Microchip PIC17C756A-16/L stands out as a high-integration, performance-oriented 8-bit microcontroller. Its combination of ample OTP memory, a high-speed core, and an extensive suite of advanced peripherals makes it an exceptionally capable single-chip solution for developers seeking to reduce system complexity and cost in their final designs.
