替代PIC16C56台系单片机MDT10P10、MDT2010

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 1.0 K(for
MDT2010) bytes of ROM, and 32 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 : 1K words for
MDT2010
? Internal RAM size : 32 bytes
(25 general purpose registers, 7 special
registers)
? 36 single word instructions
? 14-bit instructions
? 2-level stacks
? Operating voltage : 2.3V ~ 6.0 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
instruction
? Addressing modes include direct,
indirect and relative addressing modes
? Power-on Reset (POR), only available
while PED is Disable
? Power edge-detector Reset (PED)
? Sleep Mode for power saving
? 8-bit real time clock/counter(RTCC)
with 8-bit programmable prescaler
? 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
? 4 oscillator start-up time can be
selected by programming option:
150 μs, 20 ms, 40 ms, 80 ms
? On-chip RC oscillator based
Watchdog Timer(WDT) can be operated
freely
? 12 I/O pins with their own independent
direction control
3. Applications
The application areas of this MDT2010
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.
