MDT10P123
1. General Description
This EPROM-Based 8-bit micro-controller uses a fully static CMOS design technology to achieve high speed, small size, low power and high noise immunity.On chip memory includes 2K words EPROM and 80 bytes static RAM.Four comparator inputs with external Vref(not for 18 pin package) are also provided.
2. Features
? Fully CMOS static design
? 8-bit data bus
? On chip EPROM size : 2 K words
? Internal RAM size : 80 bytes
(72 general purpose registers,
8 special registers)
? 36 single word instructions
? 14-bit instructions
? 2-level stacks
? Operating voltage : 2.3V ~ 5.5 V
? Internal RC 4MHz frequency
? Addressing modes include direct,
indirect and relative addressing
modes
? Power-on Reset (POR),
? 4 Channel comparators
? Sleep Mode for power saving
? 4 types of power edge-detector reset:
1.8v , 2.1v , always enable 1.8v and
Disable
? 8-bit real time clock/counter(RTCC)
with 8-bit programmable prescaler
? 2 oscillator start-up time can be
selected by programming option:
150 μs,20ms
? On-chip RC oscillator based
Watchdog Timer(WDT) can be
operated freely
? 12 I/O (for 18 pins package), 14 I/O
(for 20 pins package),16 I/O (for 22/24
pins package) pins with their own
independent direction control
? 16 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
The application areas of this MDT10P123 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
