The M0 companion runs at the same clock but with a simpler pipeline, handling interrupt-driven I/O (encoder edges, limit-switch debounce) without jitter on the M4's main loop. For designs that previously split control across two separate MCUs, this dual-core part collapses the BOM into one package with shared memory and no inter-processor latency beyond a mailbox write. Supply range of 2.2 V to 3.6 V. 256-LBGA (17x17 mm) package.","metaTitle":"NXP LPC4350FET256,551 ARM Cortex-M4/M0 MCU, 204 MHz","metaDescription":"NXP LPC4350FET256,551 dual-core 32-bit MCU, 204 MHz, 264K x 8 RAM, 164 I/O, -40 to 85°C, 256-LBGA.
