BAT32A279 Datasheet Ultra-low power 32-bit microcontroller
■BAT32A279 series conforms to AEC-Q100 Grade1 automotive product standard, -40~125°C operating ambient temperature, support 64~100Pin in a variety of LQFP packages. This product uses the 32bit of the high-performance ARM®Cortex®-M0+ RISC core, operating up to 64MHz, uses high-speed embedded flash memory (SRAM up to 64 KB, program/data flash up to 512KB). This product integrates a variety of standard interfaces such as I2C, SPI, UART, LIN, CAN bus and LCD bus interface. Integrated 12bit A/D converter, temperature sensor, 8bit D/A converter, comparator, programmable gain amplifier. The 12bit A/D converter can acquire external sensor signals to reduce system design costs. The 8bit D/A converter can be used for audio playback or power control. An integrated on-chip temperature sensor enables real-time monitoring of the external ambient temperature. The chip's integrated comparator supports both high-speed and low-speed operating modes, control feedback from high-speed motors in high-speed mode, and battery monitoring in low- speed mode. Integrate a variety of advanced timer modules, load 1-channel SysTick timer, 17-channel 16bit timer, 1-channel 15bit interval timer, watchdog timer and real-time clock and other functions, and can support general-purpose PWM and motor dedicated PWM and other applications.
■The BAT32A279 also features excellent low-power performance, supporting two low-power modes of sleep and deep sleep, providing design flexibility. It consumes 100uA/MHz @64MHz and consumes only power in deep sleep mode 1.5uA for battery-powered, low-power devices. At the same time, due to the integrated event linkage controller, it can realize the direct connection between hardware modules without CPU intervention, which is faster than using interrupt response. At the same time, the frequency of CPU activity is reduced, which prolongs battery life.
■These features make the BAT32A279 microcontroller family superior reliability, rich integrated peripheral functions, and excellent low-power performance, which make them widely applicable to the development of automotive products.
