• 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)
