.. VRS51x570/580 Datasheet Rev 1.2 Versa 8051 MCUs with 32/64KB Overview The VRS51x570 and the VRS51x580 are low cost 8-bit microcontrollers based on the standard 80C51 microcontroller family architecture. They are pin patible and drop-in replacements for most 8051 MCUs. Ideal for a wide range of applications requiring large amounts of program/data memory, coupled with prehensive peripheral support, the VRS51x570/580 devices include 32KB/64KB of Flash memory, respectively, and 1KB of SRAM, 5 PWM output channels, a UART, three 16-bit timers, a Watch Dog timer and power down Features . These devices also include a fifth, 4-bit, I/O port mapped into the “no connect”...
