NXP Semiconductors LPC3220FET296/01,5

Overview

LPC3220FET296/01 from NXP Semiconductors is a 32-bit ARM926EJ-S microcontroller with vector floating-point coprocessor, operating up to 266 MHz and integrating 128 kB on-chip SRAM, USB On-The-Go, Ethernet MAC (not enabled in this variant), and NAND flash interface. It targets low-power embedded applications requiring rich peripheral integration, including industrial HMI, medical instrumentation, and networked control systems.

For engineers reviewing the LPC3220FET296/01 datasheet, LPC3220FET296/01 pinout, LPC3220FET296/01 application, or LPC3220FET296/01 equivalent, key selection criteria include its TFBGA296 package, 128 kB IRAM (no Ethernet/LCD), multi-layer AHB bus architecture, and support for boot-from-NAND/SPI/USB/UART - critical for secure, field-upgradable firmware deployment in resource-constrained environments.

Technical Context

The LPC3220FET296/01 implements an ARM926EJ-S core with Harvard architecture, 5-stage pipeline, and integrated MMU enabling full virtual memory support for Linux-based OS deployments. Its dual-cache subsystem includes 32 kB instruction cache and 32 kB data cache, while the multi-layer AHB matrix provides dedicated buses for CPU, DMA, USB, LCD, and Ethernet - eliminating arbitration delays except during concurrent slave access.

Power management leverages software-controlled clock gating and stop mode operation, allowing peripherals like RTC, timers, and GPIO to retain functionality while CPU is halted. The chip integrates two NAND flash controllers (SLC/MLC), eight-channel GPDMA, and a 10-bit 400 kHz ADC with touch screen sense capability - all accessible via its 296-ball TFBGA package with defined power domains (VDD_CORE, VDD_EMC, VDD_AD, etc.).

FAQ

What is the maximum operating frequency of the LPC3220FET296/01?

The LPC3220FET296/01 operates at a maximum CPU clock frequency of 266 MHz, achieved using NXP's 90 nm process and an on-chip PLL that synthesizes the required core clock from a lower-frequency crystal or oscillator. This frequency is fully supported across the −40 °C to +85 °C industrial temperature range specified for the LPC3220FET296/01.

Does the LPC3220FET296/01 include an Ethernet MAC?

No, the LPC3220FET296/01 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 LPC3220FET296/01 retains all other core peripherals - including USB OTG, NAND interface, and 128 kB SRAM - making it ideal for non-networked control applications.

What package type and pin count does the LPC3220FET296/01 use?

The LPC3220FET296/01 uses a TFBGA296 package (SOT1048-1) with 296 solder balls arranged in a 15 mm × 15 mm footprint and 0.65 mm pitch. This package is mechanically and electrically identical across the LPC3220/30/40/50 family, ensuring layout reuse when migrating between variants - for example, upgrading to LPC3230FET296/01 for LCD support requires no PCB redesign.

Can the LPC3220FET296/01 boot directly from NAND flash?

Yes, the LPC3220FET296/01 supports direct boot from NAND flash using its integrated SLC NAND controller. Boot configuration is determined by the SERVICE pin (C15) state at reset, and the internal boot ROM initializes the NAND interface, reads the first page, and executes the secondary bootloader - enabling robust, field-upgradable firmware without external boot devices.

How much on-chip SRAM does the LPC3220FET296/01 provide?

The LPC3220FET296/01 integrates 128 kB of on-chip static RAM (IRAM), which is mapped into the ARM926EJ-S core's address space and accessible at full CPU speed. This SRAM is sufficient to host a lightweight Linux kernel, root filesystem (initramfs), and application code - eliminating the need for external RAM in many cost- and space-constrained embedded designs.
