80 MHz Cortex-M4 with FPU — processing headroom for sensor fusion and control loops
The STM32L452VCI6: It packs 256 KB of Flash and 160 KB of SRAM, enough for moderate firmware images and real-time data buffers without external memory. The 100-UFBGA (7x7 mm) package keeps the footprint tight for space-constrained PCBs.
Peripheral set — what the 83 I/O and serial interfaces unlock
The 16-channel 12-bit ADC and single 12-bit DAC cover analog front-end duties for current sensing, temperature monitoring, or audio output. Brown-out detect and DMA offload the core from housekeeping tasks.
