Product details

The LPC4337JBD144E pairs an ARM Cortex-M4 running at 204 MHz with a Cortex-M0 coprocessor. That M0 handles housekeeping — communication stack, sensor polling, watchdog — while the M4 crunches the main control algorithm or signal processing. No shared-bus contention for the critical loop; the M0 keeps the M4 from being interrupted by peripheral traffic. For an industrial gateway or motor-drive controller, that split saves a second MCU and the inter-processor wiring.

Memory map for the BOM freeze

On-chip memory: 1 MB Flash, 136 KB RAM, 16 KB EEPROM. The EEPROM stores calibration constants without external serial memory.

Frequently asked questions

Where can I buy LPC4337JBD144E and how is it quoted?

We source the LPC4337JBD144E to order against an RFQ. Availability and current pricing are confirmed at quote time through our independent distribution network.

What is the closest pin-compatible alternative to LPC4337JBD144E?

The LPC4357JBD144E is pin-compatible and offers 264 KB RAM instead of 136 KB. If your application needs more data buffer or display memory, that is the direct step-up within the same footprint.

What is the LPC4337JBD144E's core speed?

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