With 114 I/O lines in a 144-LQFP package, this MCU routes enough signals for a display interface, external memory bus, and multiple serial channels without bit-banging. That combination suits it for human-machine interface panels, motor drives with encoder feedback, and industrial gateways that bridge fieldbus to Ethernet.
It uses an ARM Cortex-M4 core, 32-bit single-core, running at 180 MHz.
256 KB of SRAM organized as 256K x 8 bits.
