Overview
The VRS1000 is an 8-bit microcontroller with 64kB Flash and 1kB of RAM. It includes an In-System / In Application Programmable (ISP/IAP) function and is based on the architecture of the standard 80C51 microcontroller. Each device contains a small ISP program residing in the upper section of the Flash memory that allows In System Programming of the Flash memory from the processor itself or through the UART interface.

Feature Set
• General 80C51/80C52 family compatible
• 64kB byte on-chip Flash memory
• In-System Programming (ISP) capability of Flash
• Program voltage: 5V
• 1024 bytes on chip data RAM
• Four 8-bit I/Os + one 4-bit I/O
• 5-Channel PWM on P1.3 to P1.7
• Full duplex serial port (UART)
• Three 16-bit Timers/Counters
• Watch Dog Timer
• Bit operation instruction
• 8-bit Unsigned Multiply and Division instructions
• BCD arithmetic
• Direct and Indirect Addressing
• Two Levels of Interrupt Priority and Nested Interrupts
• Power saving modes:
• Code protection function
• Low EMI (inhibit ALE)
• Industrial Temperature range (-40ºC to +85ºC)
• 5V version available
