Product details
Overview
LPC4330FET256 from NXP Semiconductors is a dual-core ARM Cortex-M4/M0 microcontroller for high-performance embedded control, featuring 264 kB SRAM, dual high-speed USB 2.0 interfaces (one with on-chip HS PHY), 10/100T Ethernet MAC with IEEE 1588 support, and 164 GPIO pins - deployed in industrial motor control and networked power management systems.
For engineers reviewing the LPC4330FET256 datasheet, LPC4330FET256 pinout, LPC4330FET256 application, or LPC4330FET256 equivalent, this page delivers verified core architecture details, package-specific I/O mapping, real-time peripheral timing constraints, and validated alternative MCU options for migration or second-sourcing.
Technical Context
The LPC4330FET256 integrates an ARM Cortex-M4 core running at up to 204 MHz with hardware FPU and MPU, paired with a fully independent ARM Cortex-M0 coprocessor also rated to 204 MHz - enabling asymmetric task partitioning where the M0 handles real-time I/O offload while the M4 executes complex signal processing or protocol stacks. Both cores share access to the AHB multilayer matrix but maintain separate instruction/data buses and local SRAM blocks.
Its clock system includes three PLLs: one for CPU operation, one dedicated to USB0 high-speed PHY, and a third configurable as audio PLL; combined with a 12 MHz IRC oscillator trimmed to ±1.5 % accuracy and RTC crystal oscillator support, it enables precise timing across mixed-criticality subsystems without external clock sources.

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-core microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LPC4350FET256 | Includes LCD controller and second USB PHY; same dual-core, memory, and peripheral set except LCD and USB1 PHY. | Required for HMI-integrated designs (e.g., panel meters with TFT display); unnecessary overhead if display not used. | Select when LCD interface is mandatory; otherwise LPC4330FET256 offers identical compute, connectivity, and I/O at lower cost. |
| LPC4320FBD144 | Single Cortex-M4 core, 200 kB SRAM, no Ethernet, no USB0 HS PHY, LQFP144 package (83 GPIO). | Suitable for cost-sensitive, non-networked control (e.g., HVAC fan controllers); lacks IEEE 1588, dual USB, and M0 offload capability. | Choose only for simpler applications without Ethernet, dual USB, or real-time I/O offloading - not a functional replacement. |
Compared with LPC4350FET256, the LPC4330FET256 removes LCD controller to reduce die size and cost while retaining full Ethernet, dual USB, and dual-core capability; versus LPC4320FBD144, it adds Cortex-M0 coprocessor, 64 kB more SRAM, and full high-speed USB/Ethernet - making it the optimal choice for connected, real-time embedded systems requiring deterministic I/O handling.

FAQ
What is the maximum operating frequency of the LPC4330FET256 dual-core system?
The LPC4330FET256 supports both the ARM Cortex-M4 and Cortex-M0 cores running concurrently at up to 204 MHz, enabled by three independent PLLs - one for CPU clocks, one dedicated to USB0 high-speed PHY, and one configurable for audio or other timing domains. This frequency is achievable across the full industrial temperature range (-40 °C to +105 °C) with proper power supply decoupling and thermal management.
Does the LPC4330FET256 include an integrated high-speed USB PHY?
Yes, the LPC4330FET256 integrates a full high-speed USB 2.0 PHY for USB0 (Host/Device/OTG), eliminating the need for an external transceiver. USB1 supports high-speed operation only via ULPI interface to an external PHY. The on-chip USB0 PHY complies with USB 2.0 specification and is validated for interoperability with standard USB hosts and devices.
How many GPIO pins does the LPC4330FET256 support in the LBGA256 package?
The LPC4330FET256 in LBGA256 package provides up to 164 GPIO pins, organized across 16 ports (P0–P9, PA–PF), each configurable via the System Configuration Unit (SCU). All GPIO registers reside on the AHB bus for single-cycle access, and eight pins can be selected as edge- or level-sensitive interrupt sources - including two programmable GPIO group interrupt modules.
Is IEEE 1588 time stamping supported on the LPC4330FET256 Ethernet MAC?
Yes, the LPC4330FET256's 10/100T Ethernet MAC includes full hardware support for IEEE 1588-2008 v2 Precision Time Protocol (PTP), with timestamp registers for transmit and receive frames, fine-resolution correction logic, and synchronization message filtering. This enables sub-microsecond time alignment in industrial automation networks without software intervention.
What memory resources are available on the LPC4330FET256 besides SRAM?
In addition to 264 kB of SRAM, the LPC4330FET256 includes 64 kB of ROM containing boot code and certified USB/Ethernet drivers, plus 64-bit + 256-bit One-Time Programmable (OTP) memory for secure key storage and device configuration.
