【文字介绍】

This powerful yet easy-to-program (only 35 single word instructions) CMOS Flash-based 8-bit microcontroller packs Microchip’s powerful PIC® MCU architecture and features such as KeeLoq® compatible Cryptographic Module, PLVD, 2 comparators and 256 bytes of EEPROM data memory into an 20-pin package. The addition of a Transponder Analog Front End makes this an ideal device for PKE type systems.This device is easily adapted for automotive, industrial, or appliance product applications that require field re-programmability combined with authentication security. In addition, Microchip’s nanoWatt technology provides outstanding low power performance for optimizing battery powered applications.
