Nuvoton MS51FB9AE Microcontroller

Nuvoton MS51FB9AE microcontroller in TSSOP20 package

NuMicro® MS51FB9AE is embedded with based on 1T 8051-based CMOS microcontroller, runs up to 24 MHz, features 16 K bytes flash, 1 K bytes SRAM, and 4 K bytes loader ROM for the ISP, also equipped with rich peripherals: 2 sets of UART; 1 set of I²C, and 1 set of SPI, 18 GPIO, 8 channels of 12-bit ADC, Watchdog Timer, Window Watchdog Timer and 6*16-bit PWM channel, package is available in TSSOP20.

The MS51 is an embedded flash type, 8-bit high performance 1T 8051-based microcontroller. The instruction set is fully compatible with the standard 80C51 and performance enhanced. The MS51 contains a up to 16K Bytes of main Flash called APROM, in which the contents of User Code resides. The MS51 Flash supports In-Application-Programming (IAP) function, which enables on-chip firmware updates. IAP also makes it possible to configure any block of User Code array to be used as non-volatile data storage, which is written by IAP and read by IAP or MOVC instruction, this function means whole 16K Bytes area all can be use as Data Flash through IAP command. MS51 support an function of configurationable Flash from APROM called LDROM, in which the Boot Code normally resides for carrying out In-System-Programming (ISP). The LDROM size is configurable with a maximum of 4K Bytes by CONFIG define. There is an additional include special 128 bytes security protection memory (SPROM) to enhance the security and protection of customer application. To facilitate programming and verification, the Flash allows to be programmed and read electronically by parallel Writer or In-Circuit-Programming (ICP). Once the code is confirmed, user can lock the code for security.
