Product details

At 204 MHz, the Cortex-M4 can execute a single-precision floating-point multiply-accumulate in one cycle, which translates to sub-microsecond PID updates for motor-current loops or sensor-fusion filters. 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.

Frequently asked questions

What is the closest pin-compatible alternative to the LPC4350FET256,551?

Within the LPC43xx family, the LPC4357FET256 is a pin-compatible upgrade with 1 MB of on-chip Flash (the LPC4350FET256 is ROMless). For designs that need internal program storage, the LPC4357FET256 is the direct drop-in alternative. No other pin-compatible second source exists outside the NXP LPC43xx series.

What is the LPC4350FET256,551's listed speed?

The LPC4350FET256,551 is rated for 204 MHz on both the Cortex-M4 and Cortex-M0 cores. This is the maximum CPU clock frequency; the part can be clocked lower via the PLL dividers to save power.

What series does the LPC4350FET256,551 belong to?

It is part of the NXP LPC43xx series, which features dual-core ARM Cortex-M4/M0 architecture, Ethernet, USB, CAN, and LCD controller options across the family.
