MDT2005IB Datasheet, PDF (1/15 Pages) Micon Design Technology Corporation – 8-bit micro-controller

MDT2005(IB)
1. General Description
This EPROM-Based 8-bit micro-controller
uses a fully static CMOS design technology
combines higher speeds and smaller size
with the low power and high noise immunity
of CMOS.
On chip memory system includes 0.5 K(for
MDT2005) bytes of ROM, and 32 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 : 512 words for
MDT2005
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 ~ 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 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:
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 On-chip RC oscillator based Watchdog
Timer(WDT) can be operated freely
u 12 I/O pins with their own independent
direction control
3. Applications
The application areas of this MDT2005
range from appliance motor control and
high speed automotive to low power remote
transmitters/receivers, pointing devices,
and telecommunications processors, such
as Remote controller, small instruments,
chargers, toy, automobile and PC
peripheral … etc.
