描述 Description

M253LE3AE 32-bit microcontroller is based on Arm Cortex-M23 core for Armv8-M architecture. It runs up to 48 MHz and features 128 Kbytes Flash, 16 Kbytets SRAM, 1.75V ~ 5.5V wide operating voltage, and -40°C to +105°C operating temperature.

M253LE3AE 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.

M253LE3AE 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.

Supported packages LQFP48 (7mm x 7mm) with pin-compatible for different part numbers make the system design and parts change easily.
