New Original IC ML51FB9AE

The NuMicro® ML51/ML54/ML56 series is a Flash embedded 1T 8051-based microcontroller. Theinstruction set of the ML51 series is fully compatible with the standard 80C51 with enhancedperformance; This series is a three-to-one single microcontrollers, intergrated with up to 14 channels ofcapacitive touch and LCD driver.The ML51/ML54/ML56 series is 1T 8051 core based low-power microcontrollers running at less80µA/MHz in normal run mode, and power down current is below 1uA. It Provides operating frequencyup to 24 MHz. 16KB and 32KB Flash of ML51 series voltage range supports 1.8V to 5.5V, and 64KBFlash of ML51 series supports 1.8 to 3.6V voltage range.The ML51/ML54/ML56 series microcontroller provides 3 power modes to reduce power consumption －Low power run mode, Low power Idle mode, and Power-down mode. In Low power run mode, the powerconsumption can be down to 15 uA at 38.4 kHz LIRC. In Low power idle mode, CPU processing issuspended by holding the Program Counter. No program code is fetched and run in low power idlemode if the power consumption does not exceed 13 uA. Power-down mode stops the whole systemclock for minimum power consumption with the leakage current less than 1 uA. The system clock of theML51 series can also be slowed down by software clock divider, which allows for flexibility betweenexecution performance and power consumption.The ML51/ML54/ML56 series provides rich peripherals including 256 bytes of SRAM, 4 Kbytes ofauxiliary RAM (XRAM), up to 56 general purpose I/O, two 16-bit Timers/Counters 0/1, one 16-bit Timer2with 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 errordetection and automatic address recognition, two ISO7816 Smartcard interface, two SPI, two I2C, 6enhanced PWM output channels with dead zone control, 6 PWM output channels with 3 individualconfigurable period, two analog comparators, eight-channel shared pin interrupt for all I/O ports, andone 12-bit ADC at 500 ksps. There are a total of 31 sources with 4-level-priority interrupts capability.
