NXP Semiconductors LPC2470FBD208,551

Overview

LPC2470FBD208 from NXP Semiconductors is a flashless ARM7TDMI-S microcontroller operating at up to 72 MHz, integrating an LCD controller, 10/100 Ethernet MAC with MII/RMII, dual CAN channels, USB 2.0 full-speed device/host/OTG, and 98 kB on-chip SRAM - deployed in industrial control panels requiring real-time interrupt response and high-resolution TFT display support.

For engineers reviewing the LPC2470FBD208 datasheet, LPC2470FBD208 pinout, LPC2470FBD208 application, or LPC2470FBD208 equivalent, key selection considerations include its LQFP208 package, 160 GPIO lines with VIC-interrupt capability, 10-bit ADC/DAC, dual AHB buses for concurrent Ethernet/USB DMA, and RTC-powered 2 kB battery-backed SRAM for data retention during power-down.

Technical Context

The LPC2470FBD208 implements a single-core ARM7TDMI-S processor with Thumb instruction set support and real-time debug via JTAG and embedded trace module. Its memory architecture separates 64 kB local SRAM (ARM bus), 16 kB Ethernet SRAM, 16 kB general-purpose DMA SRAM, and 2 kB RTC-domain SRAM - enabling deterministic peripheral access without bus contention.

Dual AHB bridges isolate Ethernet and USB DMA paths, while the Vector Interrupt Controller supports 32 vectored interrupts with edge/level sensitivity on 64 GPIO pins. Clocking includes a 4 MHz internal RC oscillator (±1%), external crystal range of 1–25 MHz, and PLL for CPU operation up to 72 MHz.

FAQ

What is the maximum operating frequency of the LPC2470FBD208?

The LPC2470FBD208 operates at a maximum CPU frequency of 72 MHz, achieved using its on-chip PLL driven by the internal 4 MHz RC oscillator, external crystal (1–25 MHz), or RTC oscillator. This frequency is sustained across the full industrial temperature range (−40 °C to +85 °C) with stable 3.3 V supply.

Does the LPC2470FBD208 include on-chip flash memory?

No, the LPC2470FBD208 is a flashless microcontroller. It relies on external memory via its External Memory Controller (EMC) for program storage. The device integrates 98 kB of on-chip SRAM - including 64 kB local SRAM, 16 kB Ethernet SRAM, 16 kB GP/USB DMA SRAM, and 2 kB RTC-backed SRAM - for code execution and data buffering.

Which display interfaces does the LPC2470FBD208 support?

The LPC2470FBD208 integrates a hardware LCD controller supporting both STN and TFT displays up to 1024×768 resolution in 24-bit true-color mode. It includes dedicated DMA for pixel transfer and programmable timing registers - eliminating CPU load during screen updates and enabling smooth animation in medical and POS HMIs.

How many CAN interfaces does the LPC2470FBD208 provide?

The LPC2470FBD208 provides two independent Controller Area Network (CAN) 2.0B-compliant channels. Each channel supports full CAN protocol features including message filtering, acceptance masking, and error handling - enabling dual-bus architectures in industrial automation and vehicle subsystems.

What power-saving modes are available on the LPC2470FBD208?

The LPC2470FBD208 offers four reduced-power modes: idle, sleep, power-down, and deep power-down. In deep power-down mode, current consumption drops below 10 µA while retaining RTC operation and 2 kB of battery-backed SRAM - allowing rapid wake-up via external interrupt, RTC alarm, USB activity, or Ethernet wake-on-LAN signals.
