70 I/O and peripheral set – what connects where
Seventy GPIOs in a 100-LQFP package provide enough pins for a parallel LCD interface, an external memory bus, and multiple encoder inputs alongside the standard serial buses. On-chip peripherals include a motor-control PWM, I²S audio interface, DMA controller, and a 12-bit ADC with eight channels plus a single 10-bit DAC. The brown-out detect and power-on reset are built in, so no external supervisor IC is needed for basic supply monitoring.
