Microchip PIC17C756A-33E/L: A High-Performance 8-Bit CMOS Microcontroller with OTP Memory
The Microchip PIC17C756A-33E/L stands as a robust and capable member of the renowned PIC17C family of microcontrollers. Engineered for applications demanding high computational throughput and reliable non-volatile data storage, this microcontroller integrates a powerful core with One-Time Programmable (OTP) memory, offering a compelling solution for complex embedded systems.
At the heart of this device is a high-performance 8-bit CMOS CPU, capable of operating at a clock speed of 33 MHz, yielding a 121 ns instruction cycle. This processing power enables it to handle computationally intensive tasks efficiently. The core architecture is enhanced with a hardware multiplier, significantly accelerating mathematical operations and making it suitable for control algorithms, signal processing, and other data-heavy applications.
A defining characteristic of the PIC17C756A-33E/L is its OTP (One-Time Programmable) program memory. This type of memory is programmed once and cannot be erased electrically. This provides a high level of code security and is ideal for high-volume production runs where the firmware is fully debugged and finalized, ensuring cost-effectiveness and design integrity.
The microcontroller is further equipped with a rich set of peripherals, making it a highly integrated system-on-chip solution. Key features include:
An integrated ROM-less CAN 2.0B controller for robust serial communications in automotive and industrial networks.
A 12-channel, 10-bit Analog-to-Digital Converter (ADC) for precise acquisition of analog sensor data.
Multiple timers, capture/compare/PWM modules, and serial communication ports (USART, SPI, I²C).
A large 902-byte RAM for data handling and an enhanced instruction set for improved C compiler efficiency.
Housed in a plastic shrink small outline package (SSOP), the "L" suffix denotes a lead-free package, complying with modern environmental directives. Its extended temperature range ensures reliable operation in demanding environments.
In summary, the PIC17C756A-33E/L is a versatile and powerful controller designed for developers who need a balance of speed, integrated features, and the security of OTP memory for their final product designs.
