Product details
Overview
LPC4337FET256 from NXP Semiconductors is a dual-core ARM Cortex-M4F/M0 microcontroller with 1 MB flash (512 kB per bank), 136 kB SRAM, Ethernet MAC, dual high-speed USB interfaces (USB0 Host/Device/OTG + USB1 Host/Device), and 164 GPIO pins - deployed in industrial motor control, power metering, and embedded audio gateways requiring deterministic real-time processing and peripheral offload.
For engineers reviewing the LPC4337FET256 datasheet, LPC4337FET256 pinout, LPC4337FET256 application, or LPC4337FET256 equivalent, key selection criteria include dual-core asymmetric execution capability, LBGA256 package compatibility, absence of integrated LCD controller, IEEE 1588 time stamping support, and C_CAN 2.0B interface availability.
Technical Context
The LPC4337FET256 implements an ARM Cortex-M4F core (r0p1) running up to 204 MHz with hardware FPU, MPU, NVIC, and ETM/ETB trace - paired with a fully independent ARM Cortex-M0 coprocessor (r0p0) also operating up to 204 MHz for peripheral management and interrupt handling. Both cores share access to AHB peripherals but maintain separate local memory spaces.
Its memory subsystem includes dual-bank flash with accelerator, 16 kB EEPROM, 136 kB SRAM distributed across five blocks (32 kB + 16 kB + 16 kB + 32 kB + 40 kB), and 64 kB ROM containing boot code and USB/SD/MMC drivers. The GIMA crossbar enables flexible event routing between timers, ADCs, and SCTimer/PWM modules.

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-core ARM microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LPC4357FET256 | Includes integrated LCD controller (1024×768), 1 MB flash, same dual-core architecture and LBGA256 package. | Required for HMI display integration; not suitable where display interface adds unnecessary cost or power. | Select LPC4357FET256 only when TFT/STN panel driving is needed; otherwise LPC4337FET256 reduces BOM cost and layout complexity. |
| LPC4330JET256 | Same core configuration and peripherals, but rated for -40 °C to +105 °C industrial temperature range (vs. LPC4337FET256's -40 °C to +85 °C). | Suitable for extended ambient temperature deployments such as outdoor power electronics or under-hood automotive gateways. | Choose LPC4330JET256 for high-temperature environments; LPC4337FET256 is optimized for cost-sensitive industrial controls within standard temp range. |
Compared with LPC4357FET256, the LPC4337FET256 removes LCD controller logic to reduce die size and cost while retaining identical dual-core performance, Ethernet, USB, and analog capabilities; versus LPC4330JET256, it trades extended temperature rating for lower unit price in controlled environments.

FAQ
Does the LPC4337FET256 include an integrated LCD controller?
No, the LPC4337FET256 does not include an integrated LCD controller. This feature is present only on LPC435x variants (e.g., LPC4357FET256). The LPC4337FET256 retains all other major peripherals including Ethernet, dual USB, dual ADC, and SCTimer/PWM - making it ideal for applications where display interface is unnecessary.
What is the maximum operating frequency of the Cortex-M4F core in the LPC4337FET256?
The Cortex-M4F core in the LPC4337FET256 operates at up to 204 MHz. This maximum frequency is achieved using the internal PLLs fed by the crystal oscillator (1–25 MHz range) or the 12 MHz internal RC oscillator, with full hardware FPU and MPU support enabled at all supported speeds.
How many GPIO pins does the LPC4337FET256 provide in the LBGA256 package?
The LPC4337FET256 in LBGA256 package provides up to 164 GPIO pins, organized across 16 ports (P0–P9, PA–PF). Each pin supports up to eight configurable functions via the System Configuration Unit (SCU), and GPIO registers reside on the AHB bus for zero-wait-state access.
Is the LPC4337FET256 pin-compatible with other members of the LPC43xx family in LBGA256?
Yes, the LPC4337FET256 shares identical LBGA256 pinout and ball assignment with other LPC43xx variants in the same package (e.g., LPC4357FET256, LPC4333FET256), enabling hardware reuse across performance tiers - though functional differences (e.g., LCD presence, flash size) require corresponding firmware adaptation.
Does the LPC4337FET256 support IEEE 1588 Precision Time Protocol?
Yes, the LPC4337FET256 supports IEEE 1588-2008 v2 time stamping through its integrated 10/100T Ethernet MAC. Hardware timestamping is applied to both transmit and receive frames at the MAC layer, enabling sub-microsecond synchronization accuracy in industrial Ethernet applications.
