E0C63256

The E0C63256, 4-bit Single Chip Microcomputer.The E0C63256 is a microcomputer composed of a CMOS 4-bit core CPU (E0C63000), ROM, RAM, LCD driver and timers. Since the E0C63000 core CPU executes the principle instructions in 1 or 2 cycles, it is suitable for various high-speed controller. Furthermore, the E0C63256 has built-in four-channel 8-bit A/D converter and is most suitable for applications such as control units for household electric appliances which need A/D conver-sion and liquid crystal display.

Features of the E0C63256 are:(1) CMOS LSI 4-bit parallel processing; (2) Clock: 0.5MHz to 4.5MHz (Ceramic, X'tal or CR oscillation); (3) Instruction set :.Basic instruction : 46 types (411 instructions with all); (4) Addressing mode : 8 types; (5) ROM capacity:6,144 words × 13 bits; (6) RAM capacity:256 words × 4 bits; (7) Input port :4 bits ; (8) Output port:4 bits ;(9) I/O port:8 bits;(10) LCD driver:20 segments × 4/3/2 commons .

The absolute maximum ratings of the E0C63256 can be summarized as:(1)Supply voltage:-0.3 to 7.0V; (2)LCD supply voltage:-0.3 to 7.0V; (3)Input voltage:-0.3 to VCC+0.3V; (4)Output voltage:-0.3 to VCC+0.3V.
