MS51 Industrial Series Microcontrollers (MCUs)

Nuvoton MS51 Industrial Series Microcontrollers (MCUs) are 8-bit, high-performance, embedded Flash type, and 80C51 standard compatible MCUs based on a 1T 8051 core. These MCUs feature 32Kbyte of Flash memory, up to 2Kbyte of SRAM, and 8Kbytes of main Flash (APROM). The MS51 MCUs' Flash supports the In-Application-Programming (IAP) function that enables on-chip firmware updates. These MCUs support a function of configurable Flash from APROM called LDROM, in which the Boot code resides for carrying out In-System-Programming (ISP). To reduce power consumption, the MS51 MCUs offer idle and power-down modes that are software selectable.
