Microchip 8-Bit Flash Microcontroller, 28-Pin DIP

The Microchip 8-Bit Flash Microcontroller offers low-power, high-speed flash/EEPROM technology, making it an excellent choice for a wide range of embedded applications. This advanced microcontroller features 256 bytes of EEPROM data memory and self-programming capabilities, providing flexibility and convenience during development and operation.

Equipped with a versatile set of peripherals, it includes two comparators, five channels of 10-bit analogue-to-digital (A/D) converter, and two capture/compare/PWM functions. The synchronous serial port can be configured as either a 3-wire Serial Peripheral Interface (SPI) or a 2-wire Inter-Integrated Circuit (I²C) bus, alongside a Universal Asynchronous Receiver Transmitter (USART) for robust communication options.

Designed to maximise system reliability and minimise cost by eliminating external components, this device supports power-saving operating modes and offers programmable code protection. The data EEPROM and flash program memory are readable and writable during normal operation across the full VDD range, addressed indirectly through special function registers.
