24 MHz 15uA ML51FB9AE NUVOTON Electronic Integrated Circuits

ML51FB9AEWearable devices, smart remote controls, Internet endpoint devices, smart homes, smoke detection devices, battery devices, etc.

ML51PB9AE is an enhanced 1T 8051 core microcontroller with built-in Flash. The typical power consumption in normal operation mode can reach 80 uA/MHz and the power consumption in sleep mode can be lower than 1 uA. The highest speed of this series is up to 24 MHz, and a built-in 38.4 kHz low-speed internal oscillator supports a wide voltage operating range from 1.8 V to 5.5 V. Operating temperature:-40 ℃ to 105 ℃.
ML51PB9AE contains 16 K bytes of Flash and an additional 1 K bytes of on-chip auxiliary RAM (XRAM), and is equipped with a wealth of peripherals, such as 24 general-purpose I/O, 2 sets of serial ports, 1 set of ISO-7816 interface, 2 sets I2C and 2 sets of SPI, and provide LQFP32 package.
