Industrial 8051 Series

 

NuMicro® MS51 industrial series microcontrollers is based on 1T 8051 core, running up to 24 MHz, with up to 32 Kbyte of Flash memory and up to 2 Kbyte of SRAM. It supports one high precision 24 MHz allowing ± 1 % deviation and one 10 kHz internal RC Oscillators, operating at 2.4V ~ 5.5V voltage and - 40 ℃ ~ 105 ℃.

NuMicro® MS51 is equipped with special features such as up to 15 channels of 500k SPS 12-bit ADC, up to 12 channels of PWM with independent counters and GPIO supports 20 mA driving capability, also with ESD resistivity 8 kV and EFT resistivity 4.4 kV. Combined all these above high performance features, MS51 series is suitable for high-reliability industrial and consumer applications. 

MS51 series offers 10-33 pin packages for a broad range of applications.
