Microchip Technology, Inc. PIC16C66

The PIC16C66 is an 8-bit CMOS microcontroller from Microchip Technology, Inc., featuring a high-performance RISC CPU with only 35 single-word instructions. It operates at clock speeds up to 20 MHz, with a 200 ns instruction cycle. The device supports various addressing modes and includes an eight-level deep hardware stack for interrupts. It has a wide operating voltage range of 2.5V to 6.0V and low power consumption, making it suitable for battery-operated applications. The PIC16C66 includes multiple timers, such as an 8-bit Timer0 and a 16-bit Timer1, along with a Capture/Compare/PWM (CCP) module for precise timing and control applications. It also features a synchronous serial port (SSP) for SPI and I2C communication, as well as a Universal Synchronous Asynchronous Receiver Transmitter (USART). The device supports in-circuit serial programming and has built-in brown-out reset and watchdog timer functionalities for enhanced reliability. With its combination of features, the PIC16C66 is suitable for a variety of applications, including consumer electronics, industrial control, and automotive systems. However, engineers should consider that a newer device, the PIC16F76, is available, which may offer additional benefits.
