BAT32A237 series uses the high-performance ARM Cortex-M0®+ 32bit RISC core, which can operate 48MHz, 128KB Flash Memory ,12KB SRAM,1.5K Data Flash Memory. Various communication interfaces are integtated such as I2C, SPI, UART, LIN, CAN bus, as well as analog front-end with operational amplifiers, ADC, 12bit A/ D converter,temperature sensor, 8bit D/ A converter,comparator. With the integrated event linkage controller, direct connection between hardware modules can be realized without CPU intervention, which is faster than using interrupts. The BAT32A237 microcontroller family's excellent reliability, rich integrated peripheral functions, and excellent low-power performance make it suitable for a wide range of automotive product development,such as auto lighting,auto window,auto Infotainment,wireless Charge,DC/DC automotive power supply,and all kinds of sensors application.> ARM Cortex M0+ core  > Up to 48MHz @2.0V-5.5V  > Operating voltage: 2.0V-5.5V  > Operating temperature: -40℃-125℃  > 128KB Flash  > 12KB SRAM  > 1.5KB data flash  > Up to 59 GPIOs  > Hardware multiplier and divider module  > 9 16-Bit timers  > 1 WDT  > 1 RTC Timer  > Enhanced DMA controller  > Linkage controller  > A/D conversion-up to 18 channels of high-precision 12Bit ADC, 1.06Msps  > D /A conversion-8Bit accuracy, support 2 channels  > 2 channels programmable gain booster, 4/8/10/12/14/16/32 times gain optional  > 2 channel comparator, input source and reference voltage optional  > 1 I2C standard interface, 3-6 simple I2C interfaces  > 3 UART interfaces, support LIN-Bus  > 1 CAN2.0 interface,The CAN protocol in accordance with the standard in ISO 11898  > abnormal storage space access error, hardware CRC calibration Inspection, special SFR protection to prevent misoperation  > 128-bit unique ID number  >Conforms to AEC-Q100 Grade 1 standard  > Package: LQFP64/LQFP48/QFN40/LQFP32
