Product details

The 72 MHz ARM7 core is a workhorse for moderate-throughput control loops and protocol stacks. If your application needs more headroom for heavy graphics or high-rate data logging, you'd be looking at the Cortex-M class — but for a fieldbus node or serial-to-Ethernet bridge, this memory map is well-proportioned.

Connectivity and I/O — a single-chip network node

This MCU carries Ethernet, USB OTG, CAN, and multiple UART/SPI/I²C interfaces — enough to serve as the communication hub in a multi-protocol gateway. The 8-channel 10-bit ADC and single 10-bit DAC cover basic analog front-end needs without an external converter.

Frequently asked questions

Is LPC2458FET180,551 obsolete or NRND?

The LPC2458FET180,551 is classified as NRND (Not Recommended for New Design). It is not fully discontinued, but NXP advises against using it in new designs. Existing production can continue while stock and last-time-buy options are available.

What replaces LPC2458FET180,551?

The LPC2468FET180 is the pin-compatible upgrade within the same LPC2400 family, offering more SRAM and an enhanced Ethernet controller. It is the recommended drop-in replacement for both new designs and production continuity.

What is LPC2458FET180,551's listed speed?

The core processor runs at 72 MHz, which is the maximum clock for the ARM7TDMI-S core in this device.

What does NRND mean for LPC2458FET180?

NRND means NXP does not recommend this part for new designs. It may still be available for existing production, but a last-time-buy or transition to a successor like the LPC2468FET180 is expected. Plan your BOM migration accordingly.
