32-bit ARM Cortex M3 RISC microcontroller featuring 128KB Flash program memory and 20KB RAM. This surface-mount device operates at a maximum clock rate of 25 MHz and supports a data bus width of 32 bits. It includes 67 programmable I/Os, 3 timers, and interfaces for I2C (2 channels) and UART (3 channels). The microcontroller is housed in a 48-pin QFN EP package with an exposed pad, measuring 7x7x0.95mm, and operates within a supply voltage range of 1.2V to 3.3V, with an extended temperature range of -40°C to 105°C. An 8-channel single ADC is also integrated.
