Description

The VRS51x550 and VRS51x560 are low-cost 8-bit microcontrollers based on the standard 80C51 microcontroller architecture. They are pin compatible drop-in replacements for the 8051 Ideal for a wide range of applications requiring low to midrange amounts of program/data memory, coupled with streamlined peripheral support, the VRS51x550/560 devices feature 8KB/16KB, of Flash memory (respectively), 256 bytes of RAM, a UART, three 16-bit timers, a watchdog timer and power saving modes.

The VRS51x550 is available in 3.3 (VRS51L550) or 5 volt versions (VRS51C550), while the VRS51x560 is available in a 5 volt version (VRS51C560). All devices come in PLCC-44, QFP-44 and DIP-40 packages and operate in the industrial temperature range. Flash can be programmed using a parallel programmer available from Ramtron or with a third party commercial programmer.
