BES2300

BES2300-Z Product Specification

? ?

MCU includes a FFT accelerator engine, supports up to 512 point FFT/IFFT.

MCU includes a hardware I2C master engine, which could access sensor automatically with programmed command sequence, when CPU is clock-gating. Used for moving sensor’s data into SRAM with DMA’s help. This engine is called HWI2C here.

? ? ? ?

MCU includes 3 32-bit timers and 1 watchdog, which will reboot system if not be fed.

Peripheral interfaces includes USB 2.0 high-speed device, 3 UART, 2 normal I2C master, 2 SPI up to 26MHz, I2S and SPDIF. (Numbers and features of peripheral interfaces are different by product package.) MCU Sub-block and CODECD Sub-block are connected by synchronous AHB BUS. MCU Sub-block and BT Sub-block are connected by asynchronous AHB Bridge.
