New Release | LH32M0S30 integrated ARM ®Cortex®-M0 and 24-bit ADC high-performance MCU


New product introduction


LH32M0S30

 

Product description

A high-performance MCU integrating ARM® Cortex®-M0 and 24-bit ADC conforms to industrial standards and can realize high-precision measurement of various signals such as voltage, current, photoelectricity, temperature, and pressure.
Built-in 24-bit high-precision SD ADC, ENOB is 21.25@10hz&gain=64, temperature drift is typically 2ppm/℃, and integral nonlinearity (INL) is typically 5pmm, both linearity and temperature drift indicators are integrated in the signal chain MCU The field fills the gap in the country and greatly reduces the dependence on the temperature calibration algorithm. At the same time, LH32M0S30 is embedded with rich digital peripherals including LCD, LED, SPI, I2C, UART, PWM, DMA, etc., which greatly expands the various applications of LH32M0S30.
