MDT10P223
1. General Description
This EPROM-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
EPROM and 80 bytes static RAM.
Four comparator inputs with external Vref
(not for 18 pin package) are also provided.
2. Features
Fully CMOS static design
8-bit data bus
On chip EPROM size : 2 K words
Internal RAM size : 80 bytes
(72 general purpose registers, 8
special registers)
36 single word instructions
14-bit instructions
2-level stacks
Operating voltage : 2.3V ~ 5.5 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
Power-on Reset (POR),
4 Channel comparator
Power edge-detector Reset
4 types of power edge-detector reset:
1.8v , 2.1v , always enable 1.8v and
Disable
Sleep Mode for power saving
