NXP Semiconductors LPC2458FET180,551

Overview

LPC2458FET180 from NXP Semiconductors is a 32-bit ARM7TDMI-S microcontroller operating at up to 72 MHz, featuring 512 kB flash, 98 kB SRAM (including 16 kB Ethernet buffer and 2 kB RTC-powered RAM), dual CAN channels, 10/100 Ethernet MAC with MII/RMII, USB 2.0 Device/Host/OTG controller with on-chip PHY, and 136 GPIO pins. It is deployed in industrial gateways requiring real-time protocol bridging between CAN, Ethernet, and USB.

For engineers reviewing the LPC2458FET180 datasheet, LPC2458FET180 pinout, LPC2458FET180 application, or LPC2458FET180 equivalent, key selection criteria include Ethernet+USB+CAN co-integration, 72 MHz deterministic execution from flash, TFBGA180 package compatibility, and support for dual AHB buses enabling concurrent DMA transfers across Ethernet, USB, and memory subsystems.

Technical Context

The LPC2458FET180 implements an ARM7TDMI-S core with JTAG and embedded trace debug interfaces, executing both 32-bit ARM and 16-bit Thumb instructions. Its dual Advanced High-performance Bus (AHB) architecture isolates Ethernet and USB DMA traffic from CPU instruction fetches, eliminating bus contention during high-throughput data transfer.

It integrates dedicated peripherals including a 10-bit ADC with 8-channel multiplexing, 10-bit DAC, two PWM units supporting three-phase motor control, four 32-bit timers with capture/compare capability, and an SD/MMC interface - all accessible via configurable pin muxing and managed by an Advanced Vectored Interrupt Controller (VIC) supporting up to 32 vectored interrupts.

FAQ

What is the maximum operating frequency of the LPC2458FET180?

The LPC2458FET180 operates at a maximum CPU frequency of 72 MHz. This speed is achieved using the on-chip PLL driven by either the main crystal oscillator (1–25 MHz), internal 4 MHz RC oscillator, or RTC oscillator. The 128-bit wide flash interface and accelerator enable zero-wait-state execution at this rate, ensuring deterministic real-time performance for time-critical applications.

Does the LPC2458FET180 support both USB Device and USB Host modes simultaneously?

Yes, the LPC2458FET180 integrates a USB 2.0 full-speed Device/Host/OTG controller with on-chip PHY and 4 kB of dedicated endpoint RAM. It supports simultaneous Device and Host operations through its dual-port architecture - port 1 and port 2 can be independently configured as Device, Host, or OTG, enabling applications like USB-to-CAN bridges that enumerate as a device to a PC while acting as host to USB peripherals.

How many CAN interfaces does the LPC2458FET180 include, and are they fully compliant?

The LPC2458FET180 includes two independent Controller Area Network (CAN) 2.0B-compliant controllers. Each supports standard and extended frame formats, bit rates up to 1 Mbps, and full message object management. Both CAN modules operate autonomously with dedicated acceptance filters and transmit/receive buffers, enabling robust multi-bus automotive or industrial networking without external transceivers beyond physical layer drivers.

What type of package is used for the LPC2458FET180, and what are its mechanical dimensions?

The LPC2458FET180 uses a TFBGA180 (Thin Fine-Pitch Ball Grid Array) package, designated SOT570-3. Its body measures 12 mm × 12 mm × 0.8 mm with 180 solder balls arranged in a 0.8 mm pitch array. This high-density package supports fine-pitch routing and thermal dissipation suitable for compact industrial and medical PCB designs requiring >100 I/O signals.

Can the LPC2458FET180 execute code directly from its internal flash memory at full speed?

Yes, the LPC2458FET180 executes sequential instructions from its 512 kB on-chip flash memory at the full 72 MHz system clock rate. This is enabled by a dedicated 128-bit wide flash memory interface and instruction accelerator - a feature exclusive to the LPC2000 ARM microcontroller family. No wait states are required, delivering deterministic timing critical for real-time control loops and interrupt service routines in the LPC2458FET180.
