Product details
Overview
LPC3240FET296/01 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, 10/100 Ethernet MAC, and TFBGA296 package. It integrates USB OTG, NAND flash controllers, LCD controller (not enabled in this variant), and supports industrial networking, medical instrumentation, and embedded control systems requiring deterministic real-time response and peripheral integration.
For engineers reviewing the LPC3240FET296/01 datasheet, LPC3240FET296/01 pinout, LPC3240FET296/01 application, or LPC3240FET296/01 equivalent, key selection criteria include its 266 MHz ARM926EJ-S core with MMU, dual NAND flash controller support, 74-interrupt capability via MIC/SIC hierarchy, and Ethernet-enabled AHB bus architecture optimized for high-throughput data acquisition and protocol bridging.
Technical Context
The LPC3240FET296/01 implements an ARM926EJ-S core with Harvard architecture, 5-stage pipeline, and integrated MMU-enabling full virtual memory support for Linux and other multi-tasking OS environments. Its VFP coprocessor accelerates floating-point math, while the 32 kB instruction and 32 kB data caches reduce memory latency for real-time control loops.
A multi-layer AHB matrix provides dedicated buses for CPU (instruction/data), DMA (two data paths), USB, LCD, and Ethernet MAC-eliminating arbitration delays unless concurrent access to the same slave occurs. The external memory controller supports DDR/SDR SDRAM and static devices, with separate chip selects and byte lane controls for flexible memory subsystem design.

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 and identical Ethernet, SRAM, and package-adds TFT/STN display support not present in LPC3240FET296/01. | Suitable for HMI-integrated gateways where local display is required; LPC3240FET296/01 is preferred when display is omitted to reduce cost and power. | Select LPC3250FET296/01 only if LCD interface is needed; otherwise LPC3240FET296/01 offers identical networking and compute capability at lower unit cost. |
| AT91SAM9G25-CU | ARM926EJ-S core at 400 MHz, 128 kB SRAM, no VFP, single NAND controller, no RTC with independent power domain. | Better raw CPU performance but lacks dual NAND support and battery-backed RTC-less suitable for long-term unattended data logging. | Choose AT91SAM9G25-CU for higher clock-driven throughput where VFP and dual NAND are unnecessary; LPC3240FET296/01 excels in mixed-signal, power-aware, and storage-redundant designs. |
Compared with LPC3250FET296/01, LPC3240FET296/01 removes LCD functionality to reduce pin count utilization and dynamic power, while retaining identical Ethernet, memory, and security features; versus AT91SAM9G25-CU, it trades peak clock speed for integrated VFP, dual NAND, and robust RTC-making it superior for deterministic real-time and data-integrity-critical applications.

FAQ
What is the maximum operating frequency of the LPC3240FET296/01?
The LPC3240FET296/01 operates at a maximum CPU clock frequency of 266 MHz, achieved using NXP's 90 nm process and on-chip PLL. This frequency is sustained under full peripheral load within the −40 °C to +85 °C industrial temperature range, as validated in the official NXP datasheet Rev. 2.1.
Does the LPC3240FET296/01 include an integrated LCD controller?
No, the LPC3240FET296/01 does not include an enabled LCD controller. While the silicon die contains the LCD controller block, Table 2 in the datasheet explicitly states "LCD controller = 0" for this variant. In contrast, LPC3230FET296/01 and LPC3250FET296/01 list LCD controller = 1.
How many Ethernet interfaces does the LPC3240FET296/01 support?
The LPC3240FET296/01 integrates one 10/100 Ethernet MAC with dedicated DMA controller. As confirmed in Table 2 of the datasheet, "10/100 Ethernet = 1" for this part number-distinguishing it from LPC3220FET296/01 (Ethernet = 0) and matching LPC3250FET296/01.
What type of internal memory is included in the LPC3240FET296/01?
The LPC3240FET296/01 includes 256 kB of on-chip static RAM (IRAM), 32 kB instruction cache, and 32 kB data cache. It also contains 16 kB ROM for boot code and a 32-byte RTC scratchpad. No on-chip flash is present-the device boots from external NAND, SPI, or USB.
Is the LPC3240FET296/01 pin-compatible with other LPC32xx variants in the TFBGA296 package?
Yes, all LPC32xx parts in the TFBGA296 package-including LPC3220FET296/01, LPC3230FET296/01, LPC3240FET296/01, and LPC3250FET296/01-share identical pinout and footprint (SOT1048-1). Functional differences (e.g., LCD presence, Ethernet) are implemented via internal configuration, not pin assignment.
