Main features of ML51PC0AE

2020-07-03

ML51PC0AE is an enhanced 1T 8051 core microcontroller with built-in Flash. The typical power consumption in normal operation mode can reach 80 μA/MHz and the power consumption in sleep mode can be less than 1 μA. 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 of 1.8 V to 5.5 V. Operating temperature:-40 ℃ to 105 ℃.


ML51PC0AE contains 32 K bytes of Flash and an additional 2 K bytes of on-chip auxiliary RAM (XRAM), equipped with a wealth of peripherals, such as 28 general-purpose I/O, 2 serial ports, 1 ISO-7816 interface, 2 groups I²C and 2 sets of SPI are available in LQFP32 package.


Target application:Wearable devices, smart remote controllers, Internet endpoint devices, smart homes, smoke detection devices, battery devices, etc.
