This is powerful (200 nanoseconds command execution) yet easy to program ( only 35 single-word commands) The CMOS FLASH-based 8-bit microcontroller packs Microchip's powerful PIC® architecture into a 28-pin package and is upwardly compatible with PIC16C5X, PIC12CXXX and PIC16C7X devices. The PIC16F870 includes 64 bytes of EEPROM data memory, self-programming, an ICD, a 5-channel 10-bit Analog-to-Digital (A/D) converter, 2 additional timers, a capture/compare/PWM functions, and a Universal Asynchronous Receiver. Transmitter (USART). All these features make it ideal for more advanced A/D applications in automotive, industrial, appliance and consumer applications.
