VG509A
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 consumption and high noise
immunity. On chip memory includes 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 : 47 bytes
(41 general purpose registers, 6 special
registers)
36 single word instructions
14-bit instructions
2-level stacks
