VRS51x550/560
Datasheet
Rev 1.3
Versa 8051 MCUs with 8/16KB Flash
Overview
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
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.
