Description

The VRS51C1000 is based on the standard 8051 microcontroller family architecture and is pin compatible and a drop-in replacement for most 8051 MCUs.

The VRS51C1000 is ideal for a range of applications requiring 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, IKB of SRAM, 5 PWM output channels, a UART, three 16-bit timers, a Watchdog timer and power down features.

The VRS51C1000 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 device also includes a fifth, 4-bit, I/O port mapped into the "no connect" pins of the standard 8051/52 package, providing a total of 36 I/Os while maintaining compatibility with standard 8051/82 pin outs.

The VRS51C1000 is available in PLCC-44, QFP-44 and DIP-40 packages and function over the industrial temperature range.
