Nuvoton – MS51 Industrial Series – 8 Bit T1 8051-MCU for cost efficient industrial design having the need for long term availability

Nuvoton - MS51 Industrial Series

NuMicro® MS51 industrial series microcontrollers are based on 1T 8051 core (single cycle execution), running up to 24 MHz, with up to 32 Kbyte of Flash memory and up to 2 Kbyte of SRAM.

With its high precision 24 MHz internal RC oscillator trimmed to ± 1 % deviation (@VDD=5V) and a slow 10 kHz internal RC Oscillators it can operate at 2.4V ~ 5.5V voltage and – 40 ℃ ~ 105 ℃.

NuMicro MS51 Industrial Series in Detail

Nuvoton - MS51 Industrial SeriesNuMicro® MS51 is equipped with special features such as 12-bit ADC with up to 15 channels @ 500ksps, up to 12 channels of PWM outputs with independent counters and GPIO supporting up to 20 mA driving capability.

With an ESD resistivity of 8 kV and EFT resistivity of 4.4 kV these MCUs can cope with harsh industrial environment or applications where electrical stress can occur on user interaction. Combined all these above high-performance features, MS51 series is suitable for high-reliability industrial and consumer applications.
