MDTIC MDT10P7212S11 8-bit micro-controller Datasheet

MDT10P7212
-8 analog inputs multiplexed into one A/D
1. General Description
converter
This EPROM-Based 8-bit micro-controller uses a fully
-10-bit resolution
static CMOS technology process to achieve higher
TMR0: 8-bit real time clock/counter
speed and smaller size with the low power consumption
TMR1: 16-bit real time clock/count
and high noise immunity. On chip memory includes 4K
TMR2: 8-bit clock/counter (internal)
words of ROM, and 192 bytes of static RAM.
5 types of oscillator can be selected by
programming option:
RC－Low cost RC oscillator
2. Features
LFXT－Low frequency crystal oscillator
The followings are some of the features on the
XTAL－Standard crystal oscillator
hardware and software:
HFXT－High frequency crystal oscillator
Fully CMOS static design
IRC－Internal 8MHz RC oscillator
8-bit data bus
On-chip RC oscillator based Watchdog Timer
On chip EPROM size: 4.0 K words
(WDT)
Internal RAM size: 192 bytes
18/20 I/O pins with their own independent direction
37 single word instructions
control
14-bit instructions
8-level stacks
3. Applications
Operating voltage: 2.5 V ~ 5.5 V (PRD Disable)
4.5 V ~ 5.5 V (PRD Enable)
The application areas of this MDT10P7212 range from
Operating frequency: DC ~ 20 MHz
appliance motor control and high speed auto-motive to
The most fast execution time is 200 ns under 20
low
