E0C6266 Datasheet | Epson

DESCRIPTION The E0C6266 is an advanced single-chip CMOS 4-bit microputer consisting of the E0C6200 CMOS 4-bit core CPU. It also contains the ROM, RAM, 2-channel timer, event counter, start-stop serial ports, clock sync serial ports and 40 I/O ports. The E0C6266 provides an excellent solution for low-power consumption systems with clock functions. s FEATURES q CMOS LSI 4-bit parallel processing q Clock 38.4k Hz (Typ.)/500k Hz (Max.)
