Microchip Technology, Inc. Microcontrollers PIC16F874-04/P

The PIC16F874-04/P is an 8-bit CMOS FLASH microcontroller featuring a high-performance RISC CPU with a maximum operating frequency of 20 MHz. It supports up to 8K x 14 words of FLASH program memory, 368 bytes of RAM, and 256 bytes of EEPROM. The device is designed with a low power consumption profile, drawing less than 0.6 mA at 3V and 4 MHz, and includes various power-saving modes. This microcontroller offers a range of peripheral features, including three timers, two capture/compare/PWM modules, and a 10-bit multi-channel analog-to-digital converter. It also supports serial communication protocols such as SPI and I¬=C, as well as a USART for asynchronous communication. The device is equipped with multiple interrupt sources and has a robust set of features for in-circuit programming and debugging. The PIC16F874-04/P operates over a wide voltage range of 2.0V to 5.5V and is available in a 40-pin DIP package. Its compatibility with existing PIC16C73B/74B/76/77 pinouts makes it suitable for various applications, particularly in commercial and industrial environments.
