Versa 8051 MCU with 128KB of IAP/ISP Flash
Overview
The VRS51C1100 is based on the standard 8051
microcontroller architecture and is a pin compatible
drop-in replacement for the 8051.
The VRS51C1100 is aimed at a diversity of applications
that require a large amount of program/data memory
with non-volatile data storage and/or code/field based
firmware
upgrade
capability
coupled
with
comprehensive peripheral support. It features 64KB of
In-System/In-Application Programmable Flash memory,
64KB Data Flash memory, 1KB of RAM, 4 PWM
outputs, a UART, three 16-bit timers/counters, a
watchdog timer and power down features.
The VRS51C1000 is available with firmware that
enables In-System Programming (firmware based boot-
loader) of the Flash memory via the UART interface
(ISPVx version). General Flash memory programming
is supported by device programmers available from
Ramtron or other 3rd party commercial programmer
suppliers.
The VRS51C1100 is available in PLCC-44, QFP-44
and DIP-40 packages and functions over the industrial
temperature range.
