S1C63408

S1C63408 4-bit Single Chip Microcomputer ● ● ● Original Architecture Core CPU Low Current Consumption High Speed Operation in Low Voltage „ DESCRIPTION The S1C63408 is a microcomputer which has a high-performance 4-bit CPU S1C63000 as the core CPU, code ROM, RAM, data ROM, serial interface, watchdog timer, programmable timer, time base counters (2 systems) and a dot-matrix LCD driver. Furthermore, the built-in reset circuit (with power-on reset function) can detect the power supply voltage to reset the S1C63408 when the power is turned on or an instantaneous power interruption occurs. The S1C63408 features high speed operation with a low operating voltage (1.3 V to 3.6 V) and low current consumption, this makes it suitable for applications working with batteries, such as portable MD and CD player systems. „ FEATURES OSC1 oscillation circuit OSC3 oscillation circuit Instruction set Instruction execution time 32.768 kHz (Typ.) crystal or 60 kHz (Typ.)
