The VRS51x540 is a low-cost 8-bit microcontroller based on the standard 80C51 microcontroller family architecture. It is pin compatible and can be used as a drop-in replacement for standard 8051 MCUs. The product is aimed at cost-effective applications requiring small amounts of program/data memory coupled with streamlined peripheral support. The VRS51x540 includes 4KB of Flash memory, 128 bytes of RAM, a UART, three 16-bit timers, a Watchdog timer, and power down features. The VRS51x540 is available in 5V (VRS51C540) and 3.3V (VRS51L540) versions in PLCC-44, QFP-44, and DIP-40 packages. The devices operate over the entire industrial temperature range. The Flash memory can be programmed using programmers available from Ramtron or other third-party commercial programmers.
