VG509A

1. General Description

RC－Low cost RC oscillator

LFXT－Low frequency crystal oscillator

XTAL－Standard crystal oscillator

HFXT－High frequency crystal oscillator

3 oscillator start-up time can be selected

by programming option

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 consumption and high noise

immunity. On chip memory includes 1K

words of ROM, and 41 bytes of static RAM.

◆

8-bit real time clock/counter(RTCC)

with 8-bit programmable prescaler

2. Features

◆

On-chip RC oscillator based Watchdog

Timer(WDT)

Wake-up from sleep on pin change

The followings are some of the features on

the hardware and software:

◆

Fully COMS static design

8-bit data bus

3. Applications

The application areas of this VG509A 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.

On chip EPROM size : 1 K words

Internal RAM size : 47 bytes

(41 general purpose registers, 6 special

registers)

◆

36 single word instructions

14-bit instructions

4. Pin Assignment

VG509A

2-level stacks

Operating voltage : 2.5 V ~ 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

5. Packages available:

◆

Addressing modes include direct,

indirect and relative addressing modes

PDIP8

SOP8

◆

Power-on Reset

Sleep Mode for power saving

Sleep current @ 5V 5.0 A, WDT Enable

◆

5 types of oscillator can be selected by

programming option:

INTRC－Internal 4 MHz RC oscillator
