FEATURES

? RC oscillation circuit on chip

· Main system clock: fCC = 3.6 MHz (typical value with 6.8-kW external resistor connected. An internal

10-pF (typ.) capacitor is provided.)

· Subsystem clock : fCT = 47 kHz (typ.) (Both a resistor and a capacitor are provided internally.)

? Processing can be started immediately after standby mode is released.

? Oscillation of the subsystem clock can be stopped in STOP mode.

? Supply voltage: VDD = 2.5 to 5.5 V

? On-chip memory

· Program memory (ROM) : 4096 ′ 8 bits

· Data memory (RAM) : 256 ′ 4 bits

? Variable instruction execution time function useful for power saving

· 1.1, 2.2, 4.4, 17.8 ms (in fCC = 3.6 MHz operation)

· 85.1 ms (in fCT = 47 kHz operation)

? Programmable LCD controller/driver on chip

? Sold as a pellet/wafer to make it possible to be built into portable devices with an LCD display function
