1. General Description
This EPROM-Based 8-bit micro-controller uses a fully
static CMOS technology process to achieve higher
speed and smaller size with the low power
consump-tion and high noise immunity. On chip
memory incl-udes 1K words of ROM, and 68 bytes of
static RAM.

u Operating voltage : 2.5 V ~ 5.5 V (PRD Disable)
4.5 V ~ 5.5 V (PRD Enable)
3. Applications
u Operating frequency : DC ~ 20 MHz
u The most fast execution time is 200 ns under
20 MHz in all single cycle instructions except
the branch instruction
u Addressing modes include direct, indirect and
relative addressing modes
u Power-on Reset
The application areas of this MDT10P61 range from
appliance motor control and high speed automotive
to low power remote transmitters/receivers, pointing
devices, and telecommunications processors, such
as Remote controller, small instruments, chargers,
toy, automobile and PC peripheral … etc.
u Power edge-detector Reset
