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)
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
