MDT2020FF Datasheet, PDF (1/16 Pages) Micon Design Technology Corporation – 8-bit micro-controller

1. General Description
This EPROM-Based 8-bit micro-controller
uses a fully static CMOS design
technology combines higher speed and
smaller size with the low power and high
noise immunity of CMOS.
On chip memory system includes 2.0 K
bytes of ROM, and 80 bytes of static
RAM.
2. Features
The followings are some of the features
on the hardware and software :
Fully CMOS static design
8-bit data bus
On chip ROM size : 2 K words
Internal RAM size : 80 bytes
(72 general purpose, 8 special registers)
36 single word instructions
14-bit instructions
2-level stacks
Operating voltage : 2.3 V ~ 6.0 V
Operating frequency : 0 ~ 20 MHz
The most fast execution time is 200
ns under 20 MHz in all single cycle
instructions except the branch
instruction.
Addressing modes include direct,
indirect and relative addressing
modes
MDT2020(FF)
Power-on Reset (POR), only
available while PED is Disable
