It includes an In-System / InApplication Programmable (ISP/IAP) function and is based on the architecture of the standard 80C51 microcontroller. Each device contains a small ISP program residing in the upper section of the Flash memory that allows InSystem Programming of the Flash memory from the processor itself or through the UART interface. The VRS1000’s features and powerful instruction set make it a versatile and cost effective controller for applications that require non volatile data storage or that require the ability to perform its own Firmware code update. The on-chip Flash memory can be programmed via a serial interface using the ISP feature. Programming of the VRS1000 is supported by programmers available from Goal Semiconductor or other 3rd party commercial programmers. The VRS1000 is available in PLCC-44 or QFP-44 packages in industrial temperature range.
