Product details
Overview
LPC3240FET296/01K 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, 10/100 Ethernet MAC, USB 2.0 On-The-Go, and external memory controller supporting DDR/SDR SDRAM - deployed in industrial network gateways requiring deterministic real-time I/O and secure connectivity.
For engineers reviewing the LPC3240FET296/01K datasheet, LPC3240FET296/01K pinout, LPC3240FET296/01K application, or LPC3240FET296/01K equivalent, this page delivers verified package mapping (TFBGA296), confirmed Ethernet + USB OTG + EMC interface capabilities, validated peripheral register-level functions (e.g., dual NAND controllers, 7 UARTs, 6 timers), and direct alternative part comparisons for migration or second-sourcing.
Technical Context
The LPC3240FET296/01K implements an ARM926EJ-S core with Harvard architecture, 5-stage pipeline, and integrated MMU enabling full virtual memory support for Linux-based embedded systems. Its multi-layer AHB matrix provides dedicated buses for CPU instruction/data, DMA, USB, LCD, and Ethernet - eliminating arbitration delays unless concurrent slave access occurs.
It integrates two NAND flash controllers (SLC and MLC), a 10-bit 400 kHz ADC with touch screen option, RTC with independent power domain and 32-byte scratchpad, and a motor control PWM block. The external memory controller supports DDR/SDR SDRAM and static devices via 32-bit data bus and 24-bit address bus with configurable timing registers.

Equivalent & Alternatives
The following parts are listed as comparable options for similar ARM9-based microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LPC3250FET296/01 | Includes LCD controller (LPC3240 omits it); otherwise identical SRAM, Ethernet, USB, and peripheral set. | Required when driving TFT/STN displays directly; unnecessary if display is handled externally or omitted. | Select LPC3250FET296/01 only if LCD interface is needed - same pinout and software compatibility reduce redesign effort. |
| AT91SAM9G45-CU | ARM926EJ-S core at 400 MHz, 128 MB DDR2 support, but lacks dual NAND controllers and integrated USB OTG PHY. | Better suited for high-throughput multimedia applications; less optimal for NAND-based firmware updates or USB peripheral hosting. | Choose AT91SAM9G45-CU for higher CPU bandwidth and larger memory capacity; accept added complexity for external NAND management and USB transceiver. |
Compared with LPC3250FET296/01, the LPC3240FET296/01 saves board space and cost by omitting LCD-specific pins and circuitry while retaining identical Ethernet, USB OTG, and NAND functionality; versus AT91SAM9G45-CU, it offers tighter integration for NAND-based field-upgradeable systems but trades peak clock speed for lower power and simpler USB implementation.

FAQ
What is the maximum operating frequency of the LPC3240FET296/01K?
The LPC3240FET296/01K operates at a maximum CPU clock frequency of 266 MHz, achieved via an on-chip PLL that multiplies the input crystal or oscillator signal. This frequency is fully supported across the −40 °C to +85 °C industrial temperature range and enables real-time execution of protocol stacks and application logic without throttling.
Does the LPC3240FET296/01K include an integrated Ethernet MAC?
Yes, the LPC3240FET296/01K includes a fully featured 10/100 Ethernet MAC with dedicated DMA controller, supporting IEEE 802.3 compliance, full-duplex operation, and MII/RMII interface modes. It does not integrate a PHY; external magnetics and PHY IC are required for physical layer connectivity.
How much on-chip SRAM does the LPC3240FET296/01K provide?
The LPC3240FET296/01K provides 256 kB of on-chip static RAM (IRAM), mapped into the ARM926EJ-S address space as fast-access memory. This SRAM is used for boot code, stack, heap, and real-time buffers - eliminating latency penalties associated with external memory access during critical operations.
Is the LPC3240FET296/01K pin-compatible with other members of the LPC32xx family?
Yes, the LPC3240FET296/01K shares the same TFBGA296 package (SOT1048-1) and pinout with LPC3220FET296/01, LPC3230FET296/01, and LPC3250FET296/01. Functional differences (e.g., presence/absence of LCD controller or Ethernet) are implemented internally - allowing hardware reuse across variants with only firmware configuration changes.
What types of NAND flash memory does the LPC3240FET296/01K support?
The LPC3240FET296/01K supports both single-level cell (SLC) and multi-level cell (MLC) NAND flash through two independent controllers, each with hardware ECC generation and correction. It handles standard NAND commands, bad-block management, and wear leveling - enabling robust firmware storage and field upgrades without external NAND controllers.
