NuTiny-MS51FB is the specific development tool for 8-bit high performance 1T 8051-based microcontroller MS51 16K flash size series. User can use NuTiny-MS51FB to develop and verify the application program easy.


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. The MS51 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. The MS51 is equipped with three clock sources and supports switching on-the-fly via software. The three clock sources include external clock input, 10 kHz internal oscillator, and one 16 MHz internal precise oscillator that is factory trimmed to ±1% at room temperature. The MS51 provides additional power monitoring detection such as power-on reset and 4-level brown-out detection, which stabilizes the power-on/off sequence for a high reliability system design.
