` P509(A)1. General Description
This EPROM-Based 8-bit micro-controller uses a fully
static CMOS technology process to achieve higher
speed and smaller size with the low power
consump-tion and high noise immunity. On chip
memory inclu-des 1K words of ROM, and 41 bytes of
static RAM.
2. Features
The followings are some of the features on the
hardware and software :
? Fully COMS static design
? 8-bit data bus
? On chip EPROM size : 1 K words
? Internal RAM size : 41 bytes
? 36 single word instructions
? 14-bit instructions
? 2-level stacks
? Operating voltage : 2.5 V ~ 5.0 V
? Operating frequency : 4 MHz or 8 MHz
? The most fast execution time is 500 ns under 8
MHz in all single cycle instructions except the
branch instruction
? Addressing modes include direct, indirect and
relative addressing modes
? Power-on Reset
? Sleep Mode for power saving
? Oscillator mode:
INTRC－Internal 4/8 MHz RC oscillator
? Power on start-up time : 20 ms
? 8-bit real time clock/counter(RTCC) with 8-bit
programmable prescaler
? On-chip RC oscillator based Watchdog
Timer(WDT)
? Wake-up from sleep on pin change
3. Applications
The application areas of this P509(A) range from
appliance motor control and high speed automotive
to low power remote transmitters/receivers, small
instruments, chargers, toy, automobile and PC
pe-ripheral … etc.
