MDT2020(DF)
1. General Description
This EPROM-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.
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
4 oscillator start-up time :
150
µs,
20 ms, 40 ms, 80 ms
u
8-bit real time clock/counter(RTCC) with
8-bit programmable prescaler
u
4 types of oscillator can be selected by
code options :
RC－Low cost RC oscillator
LFXT－Low frequency crystal oscillator
XTAL－Standard crystal oscillator
HFXT－High frequency crystal oscillator
u
On-chip RC oscillator based Watchdog
Timer(WDT) can be operated freely
u
20 I/O pins with their own independent
direction control
2. Features
The followings are some of the features on
the hardware and software :
u
