MDT10C23 Datasheet, PDF (1/19 Pages) List of Unclassifed Manufacturers – Fully CMOS static design, 8-bit data bus,On chip ROM size : 2 K words

1. General Description
This ROM-Based 8-bit micro-controller uses a fully
static CMOS design technology to achieve high
speed, small size, low power and high noise
immunity.
On chip memory includes 2K words ROM and80
bytes static RAM.
Four comparator inputs with external Vref (not for 18
pin package) are also provided.
