MDT10P43 Datasheet, PDF (1/10 Pages) Micon Design Technology Corporation – 8-bit Micro-controller

1. General Description
This 8-bit Micro-controller with built-in carrier
generator uses a fully static CMOS technology to
achieve high speed, small size, low power and
high noise immunity.
On chip memory includes 512 words of ROM,
and 28 bytes of static RAM.
