MDT1005
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 0.5 K bytes
of ROM, and 32 bytes of static RAM.
2. Features

u Internal RAM size : 32 bytes
(25 general purpose registers, 7 special
registers)
u 36 single word instructions
u 14-bit instructions
u 2-level stacks
u Operating voltage : 2.3V ~ 6.3 V
u Operating frequency : 0 ~ 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
u Power edge-detector Reset
u Sleep Mode for power saving
u 8-bit real time clock/counter(RTCC) with
8-bit programmable prescaler
u 4 types of oscillator can be selected by
programming option:
