They are pin-to-pin compatible and drop-in replacements for most 8051 MCUs. The VRS550 and VRS560 have 8kB and 16kB, respectively of Flash memory. Both devices have 256 bytes of RAM memory. The hardware features of these devices and their reprogrammability make them suitable for a wide range of applications. These VRS550 and VRS560 are both available in PLCC-44 and QFP-44 packages in the Industrial temperature range. The Flash memory can be programmed using programmers available from Goal Semiconductor or other 3rd party commercial programmers.
