It runs up to 48 MHz and features 64 Kbytes Flash, 16 Kbytets SRAM, 1.75V ~ 5.5V wide operating voltage, and -40°C to +105°C operating temperature.\u003c\/p\u003e\u003cp\u003eM253LD3BE includes a crystal-less USB 2.0 full speed device and one set of CAN FD interface. The USB interface supports up to 17 configurable endpoints, up to 5 VCOMs, and maximum 1 Kbytes buffer size.\u003c\/p\u003e\u003cp\u003eM253LD3BE provides plenty of peripherals such as Timers, Watchdog Timers, 5 channels of PDMA, 5 sets of UART, 2 sets of I²C, 1 set of SPI\/I²S and 1 set of Universal Serial Control Interface (USCI). It also includes high performance analog front-end circuit blocks, such as 12 channels of 12-bit 880 kSPS ADC, 6 channels of 16-bit PWM, and a temperature sensor to enhance product performance, to reduce external components and form factor simultaneously.\u003c\/p\u003e\u003cp\u003eSupported packages LQFP48 (7mm x 7mm) with pin-compatible for different part numbers make the system design and
