MDT10P257 Datasheet, PDF (1/18 Pages) Micon Design Technology Corporation – 8-bit micro-controlle

1. General Description
This EPROM-Based 8-bit micro-controller
uses a fully static CMOS design
technology to combine higher speed and
smaller size with the low power and high
noise immunity.
On chip memory system includes 2.0 K
words of ROM, and 80 bytes of static
RAM.
2. Features
The followings are some of the features
on the hardware and software :
Fully CMOS static design
8-bit data bus
On chip ROM size : 2 K words
Internal RAM size : 80 bytes
(72 general purpose, 8 special
registers)
36 single word instructions
14-bit instructions
2-level stacks
Operating voltage : 2.3 V ~ 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
instructions.
Addressing modes include direct,
indirect and relative addressing modes
Power-on Reset (POR)
4 types of power edge-detector reset:
1.8v , 2.1v , always enable 1.8v and
Disable
Sleep mode for power saving
2 oscillator start-up time :
MDT10P257
EXT-R、RC：150 μs,20ms
XT、LF ：20ms,80ms
8-bit real time clock/counter(RTCC)
with 8-bit programmable prescaler
4 types of oscillator can be selected by
user options :
RC－Low cost RC oscillator
LFXT－Low frequency crystal
oscillator
XTAL－Standard crystal oscillator
EXT-R－Low cost R oscillator
On-chip RC oscillator based Watchdog
Timer(WDT) can be operated freely
20 I/O pins with their own independent
direction control
20 I/O pins own independent weak
pull-high and can be enabled by
software.
WDT can be enabled by software if
WDT Disable is selected in user
option.
3. Applications
This MDT10P257 can be used in
appliance motor control, high speed
automotive, low power remote
transmitters/receivers, pointing devices,
and telecommunications processors.
Such as Remote controller, small
instruments, chargers, toy, automobile
and PC peripheral … etc.
