MS51FB9AE Nuvoton MCU – TSSOP-20

The MS51FB9AE Nuvoton MCU 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 MS51FB9AE contains a up 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.

The MS51FB9AE Nuvoton MCU provides rich peripherals including 256 Bytes of SRAM, 1K Bytes of auxiliary RAM (XRAM), Up to 18 general purpose I/O, two 16-bit Timers/Counters 0/1, one 16-bit Timer2 with three-channel input capture module, one Watchdog Timer (WDT), one Self Wake-up Timer (WKT), one 16-bit auto-reload Timer3 for general purpose or baud rate generator, two UARTs with frame error detection and automatic address recognition, one SPI, one I2C, five enhanced PWM output channels, eight-channel shared pin interrupt for all I/O, and one 12-bit ADC. The peripherals are equipped with 18 sources with 4-level-priority interrupts capability.
