Description

The VRS51L1050 is based on the standard 8051 microcontroller family 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 memory, 1KB of SRAM, an I²C-compatible interface, 2 PWM output channels, a UART, three 16-bit timers and the ability to exit the power down mode upon assertion of an external interrupt (INT0 / INT1).

Ideal for battery-powered applications, the VRS51L1050 registers and I/Os maintain their current value in power down mode while 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 bootloader) 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 suppliers.

The VRS51L1050 is available in PLCC-44, QFP-44 and DIP-40 packages and functions over the commercial temperature range.
