MDT1030
u Power edge-detector Reset
1. General Description
u Sleep Mode for power saving
u 4 oscillator start-up time :
150 ms, 20 ms, 40 ms, 80 ms
This ROM-Based 8-bit micro-controller
uses
a
fully static CMOS design
u 8-bit real time clock/counter(RTCC) with
8-bit programmable prescaler
technology combines higher speed and
smaller size with the low power and high
noise immunity of CMOS.
u 4 types of oscillator can be selected by
code options :
On chip memory system includes 2.0 K
bytes of ROM, and 80 bytes of static RAM.
RC-Low cost RC oscillator
LFXT-Low frequency crystal oscillator
XTAL-Standard crystal oscillator
HFXT-High frequency crystal oscillator
2. Features
u On-chip RC oscillator based Watchdog
Timer(WDT) can be operated freely
u Pull up resistors for the following pins :
PA0~PA3, PB0~PB7, /MCLR, RTCC
u Pull down resistors for the following
pins :
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 : 2.0 K words
u Internal RAM size : 80 bytes
(73 general purpose registers, 7 special
registers)
PA0~PA3, PB0~PB7, RTCC
u 12 I/O pins with their own independent
direction control
u 34 single word instructions
u 12-bit instructions
3. Applications
u 2-level stacks
u Operating voltage : 2.3 V ~ 6.3 V
u Operating frequency : 0 ~ 20 MHz
u The most fast execution time is 200 ns
under 20 MHz in all single cycle
The application areas of this MDT1030
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.
