The M4 handles the motor-control PWM loops and Ethernet stack; the M0 takes care of CAN message handling, I²C sensor polling, and the LCD refresh. That split keeps the control loop jitter off the fieldbus traffic. Program memory is 512 KB of on-chip Flash, backed by 136 KB SRAM and 16 KB EEPROM — enough for a moderate motor-drive application with a local HMI screen. The 164 I/O lines break out to a 256-LBGA package (17x17 mm), so board layout needs a four-layer stackup minimum to route the EBI/EMI and Ethernet traces cleanly. ## What the 204 MHz dual-core means for your BOM Compared to a single-core Cortex-M4 at the same clock, this part lets you run the motor-control ISR on the M4 without the M0's CAN interrupt jitter affecting it. That means you can skip an external CAN controller or a second MCU for the fieldbus gateway — one chip does both. The trade-off is the 256-ball BGA footprint: if your assembly house isn't set up for fine-pitch BGA rework, factor in a stencil and X-ray inspection step. ## Peripheral set and deployment context","metaTitle":"NXP LPC4353JET256551 32-bit Dual-Core MCU, 204MHz, 512KB Flash","metaDescription":"NXP LPC4353JET256551 dual-core ARM Cortex-M4/M0 MCU at 204MHz, 512KB Flash, 136KB SRAM, 164 I/O, Ethernet, CAN, Motor Control PWM, -40 to 105°C, 256-LBGA.
