MDT1020 Datasheet, PDF (1/18 Pages) Micon Design Technology Corporation – 8-bit micro-controller

1. General Description
This ROM-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 :
u Fully CMOS static design
u 8-bit data bus
u On chip ROM size : 2 K words
u Internal RAM size : 80 bytes
(72 general purpose, 8 special registers)
u 36 single word instructions
u 14-bit instructions
u 2-level stacks
u Operating voltage : 2.3 V ~ 6.3 V
u Operating frequency : 0 ~ 20 MHz
u The fastest 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
u Power Edge-detector Reset
u Sleep mode for power saving
