Product Summary
The XC68HC57FN is a microcontroller unit (MCU). The XC68HC57FN is a 16-bit device composed of standard on-chip peripheral modules connected by an intermodule bus. Modules include 16-bit central processor unit (CPU12), Lite integration module (LIM), Two asynchronous serial communications interfaces (SCI0 and SCI1), Serial peripheral interface (SPI), Timer and pulse accumulator module, 8-bit analog-to-digital converter (ATD), 1-Kbyte random-access memory (RAM), 4-Kbyte electrically erasable, programmable read-only memory (EEPROM), Memory expansion logic with chip selects, key wakeup ports, and a phase-locked loop (PLL).
