Product details

The NXP LPC43S37JBD144E is a 32-bit dual-core microcontroller built around an ARM Cortex-M4 running at 204 MHz and a companion Cortex-M0 core for peripheral offload or low-power housekeeping. This is a part designed for industrial control, motor drives, and networked embedded systems where a single-chip solution needs both compute headroom and connectivity.

204 MHz dual-core — what it buys you

The Cortex-M4 handles the main application code and DSP-style math at 204 MHz, while the Cortex-M0 can run a real-time control loop, manage a communication stack, or handle wake-up tasks without loading the main core. That split means you can keep a deterministic response on the M0 side while the M4 crunches data — a common pattern in motor-drive field-oriented control or multi-protocol gateway designs.

Memory and peripheral fit

The 144-LQFP package gives access to the full external bus interface (EBI/EMI) for adding SDRAM or a display controller if the on-chip RAM isn't enough.

The LPC43S37JBD144E is Active in production. No last-time-buy or obsolescence notice.

Frequently asked questions

What is the speed of LPC43S37JBD144E?

The Cortex-M4 core runs at 204 MHz, with the Cortex-M0 core available for background tasks at the same clock.

What is the closest pin-compatible alternative to LPC43S37JBD144E?

NXP's LPC43xx family shares the same 144-LQFP footprint and peripheral map across density options; the LPC43S67JBD144E offers 2 MB Flash and 264 KB SRAM in the same package for a step-up in memory without a board respin.
