Product details
Overview
LPC3220FET296/01K from NXP Semiconductors is a 32-bit ARM926EJ-S microcontroller operating up to 266 MHz, featuring a vector floating-point coprocessor, 32 kB instruction and 32 kB data cache, 128 kB on-chip SRAM, and USB On-The-Go support. It targets low-power embedded applications requiring rich peripheral integration, including NAND flash controllers, external memory interface (EMC), and multi-channel UARTs - deployed in industrial HMI and medical instrumentation.
For engineers reviewing the LPC3220FET296/01K datasheet, LPC3220FET296/01K pinout, LPC3220FET296/01K application, or LPC3220FET296/01K equivalent, key selection criteria include its TFBGA296 package with 296-ball layout, absence of Ethernet MAC and LCD controller (per part option table), and boot flexibility from NAND, SPI, or UART - critical for secure firmware recovery and field-upgradable devices.
Technical Context
The LPC3220FET296/01K implements an ARM926EJ-S core with Harvard architecture, 5-stage pipeline, and integrated MMU enabling virtual memory for Linux-based OS deployment. Its dual AHB bus matrix separates CPU instruction/data paths from DMA, USB, LCD, and Ethernet masters - eliminating arbitration delays except during concurrent slave access.
Power management leverages software-controlled clock gating and stop mode operation, while hardware features include two independent NAND flash controllers (SLC/MLC), eight-channel GPDMA, and a 10-bit 400 kHz ADC with touch screen sense capability - all mapped to dedicated APB/EMC domains with defined voltage supply domains (VDD_CORE, VDD_EMC, VDD_AD).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | ARM926EJ-S with MMU, Jazelle Java acceleration, and DSP extensions - enables real-time OS and embedded Java execution without external co-processor. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar ARM9-based microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LPC3230FET296/01 | 256 kB SRAM, includes LCD controller (STN/TFT), no Ethernet MAC - same package and pinout. | Required for embedded displays with resolution up to 1024×768; not suitable where display interface is unnecessary or handled externally. | Select LPC3230FET296/01 only when TFT/STN panel driving is required and additional SRAM justifies cost premium. |
| LPC3240FET296/01 | 256 kB SRAM, includes 10/100 Ethernet MAC with dedicated DMA, no LCD controller - same package and pinout. | Required for wired network edge nodes needing TCP/IP stack offload; incompatible with display-only use cases due to missing LCD signals. | Choose LPC3240FET296/01 when Ethernet connectivity is mandatory and external PHY integration is preferred over USB-to-Ethernet bridges. |
Compared with LPC3230FET296/01 and LPC3240FET296/01, the LPC3220FET296/01K provides minimal peripheral set optimized for cost-sensitive, non-display, non-Ethernet applications - retaining full USB OTG, NAND, and multi-UART capability while reducing SRAM to 128 kB and removing LCD/Ethernet blocks to lower power and BOM cost.

FAQ
What is the maximum operating frequency of the LPC3220FET296/01K?
The LPC3220FET296/01K operates at a maximum CPU clock frequency of 266 MHz, achieved via an on-chip PLL driven by the main oscillator. This frequency is fully supported across the −40 °C to +85 °C industrial temperature range specified for the LPC3220FET296/01K, with timing validated per NXP's published AC characteristics.
Does the LPC3220FET296/01K include an Ethernet MAC or LCD controller?
No, the LPC3220FET296/01K does not include an Ethernet MAC or LCD controller. Per Table 2 "Part options" in the official datasheet, the LPC3220FET296/01K is explicitly defined with 0 for both Ethernet and LCD controller features - distinguishing it from the LPC3240FET296/01 (Ethernet only) and LPC3230FET296/01 (LCD only).
How much on-chip SRAM does the LPC3220FET296/01K provide?
The LPC3220FET296/01K integrates 128 kB of on-chip static RAM (IRAM), directly accessible by the ARM926EJ-S core without wait states. This SRAM is distinct from cache memory and serves as primary working memory for code and data - confirmed in Table 2 of the LPC3220_30_40_50 datasheet Rev. 2.1.
What boot sources are supported by the LPC3220FET296/01K?
The LPC3220FET296/01K supports selectable boot from NAND flash, SPI memory, USB, UART, or static memory - controlled by the SERVICE pin (C15) and internal boot ROM. This flexibility enables robust field firmware recovery and secure boot chain implementation without external boot ROM.
Is the LPC3220FET296/01K pin-compatible with other LPC32xx variants?
Yes, the LPC3220FET296/01K shares the same TFBGA296 package (SOT1048-1) and identical pinout with LPC3230FET296/01, LPC3240FET296/01, and LPC3250FET296/01 - enabling hardware reuse across variants. However, unused peripherals (e.g., LCD or Ethernet signals) are unconnected internally and must be left unpopulated or terminated per design guidelines.
