Product details
Overview
LPC3230FET296/01 from NXP Semiconductors is a 32-bit ARM926EJ-S microcontroller with vector floating-point coprocessor, operating up to 266 MHz, featuring 256 kB on-chip SRAM, LCD controller (STN/TFT), NAND flash interface, and USB On-The-Go - deployed in industrial HMI and medical display systems requiring deterministic real-time response and integrated graphics.
For engineers reviewing the LPC3230FET296/01 datasheet, LPC3230FET296/01 pinout, LPC3230FET296/01 application, or LPC3230FET296/01 equivalent, key selection criteria include its TFBGA296 package compatibility, LCD controller support (LPC3230-specific), absence of Ethernet MAC (distinguishing it from LPC3240/LPC3250), and boot flexibility from NAND/SPI/USB/UART/static memory.
Technical Context
The LPC3230FET296/01 implements an ARM926EJ-S core with Harvard architecture, 5-stage pipeline, and full MMU for virtual memory support - enabling Linux and other multi-tasking OS deployments. Its dual AHB bus matrix separates CPU instruction/data paths from DMA, USB, LCD, and Ethernet controllers (though Ethernet is disabled in this variant), eliminating arbitration delays except during concurrent slave access.
It integrates two NAND flash controllers (SLC and MLC), a 10-bit 400 kHz ADC with touch screen sense capability, RTC with independent power domain and 32-byte scratchpad, and a multi-layer peripheral interconnect supporting seven UARTs (four standard + three high-speed), two I²C, two SPI/SSP, two I²S, SD card interface, and motor control PWM - all accessible via 296-ball TFBGA package with defined power domains per peripheral group.

Equivalent & Alternatives
The following parts are listed as comparable options for similar ARM9-based microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LPC3240FET296/01 | Includes 10/100 Ethernet MAC and PHY interface signals; identical CPU, SRAM, and LCD controller. | Required for wired network connectivity; lacks LPC3230's LCD-specific pin assignments on some GPIOs due to Ethernet signal routing. | Select when Ethernet is mandatory and LCD usage is secondary; verify PCB layout for ENET_RXD/ENET_TXD pin conflicts. |
| LPC3250FET296/01 | Combines both Ethernet MAC and LCD controller; same package and core specs as LPC3230FET296/01. | Suitable for converged HMI+network devices (e.g., industrial gateways); higher pin functional density increases routing complexity. | Choose for dual-role applications needing both display and Ethernet; validate thermal performance under simultaneous LCD + Ethernet load. |
Compared with LPC3240FET296/01 and LPC3250FET296/01, the LPC3230FET296/01 trades Ethernet capability for optimized LCD signal integrity and lower system power - making it ideal for display-centric, non-networked embedded systems where SRAM capacity and touch interface are prioritized over connectivity.

FAQ
What is the maximum operating frequency of the LPC3230FET296/01?
The LPC3230FET296/01 operates at a maximum CPU clock frequency of 266 MHz, achieved via an on-chip PLL that synthesizes the required clock from a lower-frequency crystal or oscillator. This frequency is sustained across the full industrial temperature range (−40 °C to +85 °C) and enables real-time execution of graphics-intensive and protocol-heavy firmware without throttling.
Does the LPC3230FET296/01 include an Ethernet MAC?
No, the LPC3230FET296/01 does not include an Ethernet MAC. Per Table 2 in the official datasheet, Ethernet functionality is only present in the LPC3240FET296/01 and LPC3250FET296/01 variants. The LPC3230FET296/01 retains full pin compatibility but omits Ethernet-related signals - allowing board reuse where networking is handled externally or omitted entirely.
Which peripherals are enabled specifically in the LPC3230FET296/01 variant?
The LPC3230FET296/01 variant includes 256 kB on-chip SRAM, LCD controller (supporting STN/TFT up to 1024×768), dual NAND flash controllers (SLC and MLC), USB 2.0 OTG, 10-bit ADC with touch screen sense, RTC with isolated power domain, and keyboard scanner - distinguishing it from LPC3220 (128 kB SRAM, no LCD) and LPC3240/LPC3250 (which add Ethernet).
What boot options are supported by the LPC3230FET296/01?
The LPC3230FET296/01 supports selectable boot from NAND flash, SPI memory, USB, UART, or static memory - configured via the SERVICE pin (C15) and internal boot ROM. This flexibility enables robust field firmware recovery, production programming via USB mass storage class, and secure boot from encrypted NAND partitions without external boot loader hardware.
Is the LPC3230FET296/01 pin-compatible with other LPC32xx family members?
Yes, the LPC3230FET296/01 is fully pin-compatible with LPC3220FET296/01, LPC3240FET296/01, and LPC3250FET296/01 in the TFBGA296 package (SOT1048-1). Signal mapping differs only for variant-specific functions (e.g., Ethernet pins are No Connect on LPC3230), enabling hardware reuse across product tiers with firmware-level feature gating.
