The ultra-low-power device incorporates the connectivity power of the universal serial bus (USB) with the high-performance ARM Cortex?-M3 32-bit RISC core operating at a 32 MHz frequency, a memory protection unit (MPU), high-speed embedded memories, a flexible static memory controller (FSMC) interface (for devices with packages of 100 pins and more) and an extensive range of enhanced I/Os and peripherals connected to two APB buses. The devices offer three operational amplifiers, one 12-bit ADC, two DACs, two ultra-low-power comparators, one general-purpose 32-bit timer, six general-purpose 16-bit timers, and two basic timers, which can be used as time bases. Moreover, the device contains standard and advanced communication interfaces: up to two I2Cs, three SPIs, two I2S, one SDIO, three USARTs, two UARTs, and a USB. The device offers up to 34 capacitive sensing channels to simply add touch sensing functionality to any application.
