MDT2030 Datasheet, PDF (1/14 Pages) List of Unclassifed Manufacturers – 8-bit micro-controller uses a fully static CMOS design technology

MDT2030
1. General Description
This ROM-Based 8-bit micro-controller uses a fully
static CMOS technology process to achieve high
speed, small size, the low power and high noise
immunity.
On chip memory includes 2K words EPROM, and
80 bytes static RAM.
2. Features

u Internal RAM size : 80 bytes
(73 general purpose registers, 7 special
registers)
u 36 single word instructions
u 14-bit instructions
u 2-level stacks
u Operating voltage : 2.3 V ~ 5.5 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 Sleep Mode for power saving
u 4 types of oscillator can be selected by
programming option:
RC Low cost RC oscillator
LFXT Low frequency crystal oscillator
XTAL Standard crystal oscillator
HFXT High frequency crystal oscillator
u 4 oscillator start-up time can be selected by
programming option:
150 µs, 20 ms, 40 ms, 80 ms
u 8-bit real time clock/counter(RTCC) with 8-bit
programmable prescaler
