Gasgoo Awards 2023 applicant: BAT32A237 from China Micro Semicon Co., Limited

Product: BAT32A237 

Description

The BAT32A237 is an automotive-grade, high-quality, 32-bit general-purpose MCU from Cmsemicon, based on the ArmCortex®-M0+ core, operating at 48 MHz and equipped with 128 KB Flash, 12 KB SRAM, and 1.5 KB dedicated Data Flash, with built-in mass storage to support efficient automotive computing. Its operating temperature is -40°C~125°C, which is suitable for complex operating conditions and harsh environments of automobiles, and the BAT32A237 has passed the reliability certification of AEC-Q100 Grade 1. The BAT32A237 integrates Comp, PGA, DAC, ADC and other high-precision analog peripherals, up to 16 channels of high-precision 12-bit ADC, supports up to 1.06Msps sample rate, and its INL is +1 LSB at 125°C. Built-in multiple communication interfaces, including one CAN2.0B, two I2Cs, three UART interfaces, and support for LIN-bus, the system is highly scalable to meet the needs of complex automotive control connections. Combined with excellent ESD and EFT anti-interference performance, and enhanced security features such as RAM parity SFR protection and CRC, the BAT32A237 can provide complete hardware assurance for automotive system operation to achieve the high anti-interference, high stability and high reliability requirements required for automotive applications. Upholding the product development concept of high performance, large margin and low power consumption, the BAT32A237 runs at a low current of 0.7uA in sleep mode and supports a wide voltage supply mode of 2.0-5.5V operating voltage, as well as low power operation mode, sleep mode and deep sleep mode.

Unique advantages

The BAT32A237 operates at -40°C~125°C and is suitable for complex operating conditions and harsh environments in automobiles. It has received AEC-Q100 Grade 1 certification for automotive grade reliability. The BAT32A237 development board integrates a CAN transceiver and supports 3.3V/5V power supply switching, while the on-board CMS-ICE8 OB debugger can realize emulation and serial printing function with only one Type-C cable, which is convenient for customers to verify products quickly.

Application

The BAT32A237 is available in QFN40, LQFP32, LQFP48 and LQFP64 packages. Based on its excellent performance, the BAT32A237 can support a wide range of automotive in-vehicle electronic control module applications, such as heating and cooling air conditioning, sensors, ambient lighting, reading lights, steering control, matrix headlights, windows, radar, T-BOX, charging interface, inverter, water pump and fan, etc.

Prospect

Cmsemicon has a detailed and complete development plan for automotive-grade products. In addition to the BAT32A237, the BAT32A337, an AEC-Q100 Grade 0 certified 32-bit automotive-grade MCU that meets ASIL-B safety standards, and the 32-bit BAT32A239 and BAT32A279 series, which have rich resources and multiple pins, will be released in the first half of 2023. In addition to making products certified by the automotive industry, Cmsemicon will continue to refine its technology and products in the field of automotive electronics, insisting on self-developed core IP and providing a more optimized product portfolio for different automotive domain controllers' requirements on MCU cores, arithmetic power, memory and communication interfaces. Currently, Cmsemicon's automotive series focusing on body, connectivity and assisted driving domains have been widely applied by customers, and subsequent products will cover more automotive domains such as autonomous driving, cockpit, chassis and power.
