VRS51L1050
Product Tech Brief
Rev 1.0
Versa 3.3 Volt 8051 MCU with 64KB of IAP/ISP Flash
General Description _________________
The VRS51L1050 is based on the standard 8051
microcontroller architecture and is a pin compatible
drop-in replacement for most 8051 MCUs.
The VRS51L1050 is designed for 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, 1KB of
SRAM, an I2C-compatible interface, three 16-bit timers,
two PWMs, a UART and the capability to exit power
down mode from an external interrupt (INT0/INT1).
Ideal for battery-powered applications, the
VRS51L1050 registers and I/Os maintain their current
value in power down mode, but the oscillator is
disabled enabling the supply current to drop below
20uA.
The VRS51L1050 is available with firmware that
enables In-System Programming (firmware based
boot-loader) of the Flash memory via the UART
interface (ISPV3 version). General Flash memory
programming is supported by device programmers
available from Ramtron and 3rd party suppliers.
The VRS51L1050 is available in PLCC-44, QFP-44
and DIP-40 packages and functions over the
commercial temperature range.
