Datasheet

Rev 1.3

Versa 8051 MCUs with 8/16KB Flash

Overview

Feature Set

80C51/80C52 pin compatible

The VRS51x550 and VRS51x560 are low-cost 8-bit

microcontrollers based on the standard 80C51

microcontroller architecture. They are pin compatible

drop-in replacements for the 8051

12 clock periods per machine cycle

8KB / 16KB on-chip Flash memory

256 Bytes on-chip data RAM

32 I/O lines on four 8-bit ports

Full duplex serial port (UART)

3, 16-bit Timers/Counters

Watchdog Timer

8-bit Unsigned Division / Multiply

BCD arithmetic

Direct and Indirect Addressing

Two levels of interrupt priority and nested interrupts

Power saving modes

Code protection function

Operates at a clock frequency of up to 40MHz

Low EMI (inhibit ALE)

Programming voltage: 12V

Ideal for a wide range of applications requiring low to

midrange amounts of program/data memory, coupled

with streamlined peripheral support, the VRS51x550/560

devices feature 8KB/16KB, of Flash memory

(respectively), 256 bytes of RAM, a UART, three 16-bit

timers, a watchdog timer and power saving modes.

The VRS51x550 is available in 3.3 (VRS51L550) or 5

volt versions (VRS51C550), while the VRS51x560 is

available in a 5 volt version (VRS51C560). All devices

come in PLCC-44, QFP-44 and DIP-40 packages and

operate in the industrial temperature range. Flash can

be programmed using a parallel programmer available

from Ramtron or with a third party commercial

programmer.

Industrial Temperature range (-40°C to +85°C)

5V and 3V versions available (see ordering information)
