Microchip PIC17C756A-33I/PT: High-Performance 8-Bit CMOS Microcontroller with OTP Memory

The Microchip PIC17C756A-33I/PT represents a robust and capable member of the renowned PIC17C family of microcontrollers. Engineered for demanding embedded control applications, this device integrates high computational performance, a rich set of peripheral features, and the reliability of One-Time Programmable (OTP) memory into a single, efficient package. Its architecture is designed to deliver a powerful and cost-effective solution for complex industrial, automotive, and consumer applications.

At the core of the PIC17C756A-33I/PT lies a high-performance 8-bit RISC CPU. Operating at a clock speed of 33 MHz, this core can execute most instructions in a single cycle, achieving a throughput of up to 8.25 MIPS. This impressive speed ensures the microcontroller can handle computationally intensive tasks and complex algorithms with ease, providing designers with ample headroom for sophisticated application logic.

A defining characteristic of this microcontroller is its OTP (One-Time Programmable) program memory. This type of memory is ideal for high-volume production runs where the firmware is fully debugged and finalized. OTP memory offers a significant cost advantage over erasable alternatives like EPROM or EEPROM, making the PIC17C756A-33I/PT an economically sensible choice for products that will not require firmware updates in the field.

The device is housed in a TQFP (Thin Quad Flat Pack) package, which provides a compact footprint while facilitating easier PCB assembly and soldering processes compared to larger packages. The extended industrial temperature range (-40°C to +85°C) ensures reliable operation in harsh environmental conditions, a critical requirement for automotive and industrial systems.

Beyond its core processing power, the PIC17C756A is packed with integrated peripherals that reduce system component count and total cost. It features a high-speed analog-to-digital converter (ADC), multiple timers/counters, capture/compare/PWM modules, and serial communication interfaces like USART and SPI. This high level of integration allows it to interface directly with sensors, actuators, and communication networks, forming a complete control unit.

ICGOODFIND: The Microchip PIC17C756A-33I/PT is a high-performance, cost-optimized OTP microcontroller that delivers exceptional processing speed and a rich peripheral set for complex embedded control systems.
