Product details

The NXP LPC3230FET296,551 is a 16/32-bit ARM926EJ-S microcontroller clocked at 266 MHz, built for peripheral-rich embedded control where a full OS or heavy data throughput is needed. With 256K x 8 on-chip RAM and no internal program memory (ROMless), this part boots from external flash or ROM via the EBI/EMI interface — a design choice that trades BOM simplicity for flexible memory sizing.

On-chip peripherals and connectivity

Connectivity spans EBI/EMI, I²C, IrDA, Microwire, SPI, SSI, SSP, UART/USART, and USB OTG, covering most industrial fieldbus and serial sensor interfaces. Three 10-bit ADCs handle analog feedback from current shunts or potentiometers.

NXP has marked the LPC3230FET296,551 as obsolete. For existing BOM lines, procurement must go through surplus or broker channels.

Package and supply

Housed in a 296-ball TFBGA (15x15 mm), surface-mount only. Supply range is 0.9 V to 3.6 V.

Frequently asked questions

What is a direct replacement for LPC3230FET296?

No official direct replacement has been published by NXP for this order code. For existing designs, verify pin-compatibility with other LPC3200 series parts through the datasheet pinout; otherwise, a redesign may be required.

Where can I buy LPC3230FET296,551?

This obsolete part is sourced and quoted to order against an RFQ through independent distribution. Submit a request for current availability and pricing — no stock or price figures are published here.

What is the core speed of LPC3230FET296,551?

The ARM926EJ-S core runs at 266 MHz, which sets the processing throughput for the entire design — sufficient for real-time control loops and moderate user interfaces.

Does LPC3230FET296 have a second source or cross-reference?

No second-source or cross-reference to another NXP part is listed in the official record. The LPC3230 is a single-sourced NXP device.
