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
