Microchip PIC17C756A-33/L: A Robust 8-Bit CMOS Microcontroller with High-Performance OTP Memory
The Microchip PIC17C756A-33/L represents a significant component in the landscape of 8-bit microcontrollers, engineered for applications demanding reliability, high speed, and non-volatile program storage. This device is fabricated with advanced CMOS technology, which provides a well-balanced combination of high performance and low power consumption, making it suitable for a diverse range of industrial, automotive, and consumer applications.
At the core of this microcontroller is a high-performance 8-bit RISC CPU. The architecture is designed to execute instructions with a high degree of efficiency, achieving a 33 ns instruction cycle time at its maximum operating frequency of 33 MHz. This speed ensures that the microcontroller can handle complex tasks and real-time processing requirements with ease, providing developers with the necessary computational power for demanding embedded systems.
A defining feature of the PIC17C756A-33/L is its On-Chip OTP (One-Time Programmable) Memory. The microcontroller is equipped with 16 Kbytes of user program memory. OTP ROM is an excellent solution for medium-to-high-volume production runs where the firmware is stable and will not require future updates. This memory type offers a cost-effective alternative to masked ROMs for prototyping and production, while providing enhanced security and reliability as the programmed code cannot be altered inadvertently.
The device includes a substantial 902 bytes of RAM for data handling and manipulation, supporting complex operational algorithms. Furthermore, it is housed in a 68-pin PLCC (Plastic Leaded Chip Carrier) package, which is robust and suitable for surface-mount technology (SMT), facilitating efficient PCB design and manufacturing.
Peripheral integration is a strong suit of this microcontroller. It features a 10-bit multi-channel Analog-to-Digital Converter (ADC), which is crucial for interfacing with analog sensors and signals in the real world. Communication capabilities are covered by both a Universal Synchronous Asynchronous Receiver Transmitter (USART) for serial communication and a Serial Peripheral Interface (SPI) for high-speed synchronous data exchange with peripherals like sensors, memories, and other microcontrollers. Additionally, it incorporates two capture/compare/PWM modules, providing precise timing control for applications such as motor control, power regulation, and waveform generation.
Operating over an extensive voltage range and its CMOS construction enables the PIC17C756A-33/L to maintain low power consumption across a wide spectrum of operating conditions. This makes it an ideal choice for power-sensitive applications.
ICGOODFIND: The Microchip PIC17C756A-33/L stands out as a powerful and self-contained embedded control solution. Its integration of a high-speed processor, secure OTP memory, and a rich set of peripherals into a single package minimizes external component count, reduces overall system cost, and enhances reliability. It is a compelling choice for designers looking to finalize a design for mass production with guaranteed code integrity.
