NXP Semiconductors LPC2460FET208,551

Overview

LPC2460FET208 from NXP Semiconductors is a flashless 32-bit ARM7TDMI-S microcontroller operating at up to 72 MHz, featuring dual AHB buses, 98 kB on-chip SRAM (including 16 kB Ethernet buffer and 16 kB USB/GP DMA RAM), MII/RMII Ethernet MAC, dual CAN 2.0B controllers, and full-speed USB 2.0 device/host/OTG with integrated PHY-designed for industrial protocol gateways and real-time communication systems.

For engineers reviewing the LPC2460FET208 datasheet, LPC2460FET208 pinout, LPC2460FET208 application, or LPC2460FET208 equivalent, key selection criteria include Ethernet + dual CAN integration, TFBGA208 package compatibility, 160 GPIO with VIC interrupt mapping, 10-bit ADC/DAC, and support for external SDRAM via EMC in resource-constrained embedded designs.

Technical Context

The LPC2460FET208 implements an ARM7TDMI-S core with JTAG and embedded trace debug interfaces, executing both ARM and Thumb instruction sets to balance performance and code density. Its dual AHB architecture isolates Ethernet and USB DMA traffic to prevent bus contention-critical for deterministic real-time packet handling.

Peripheral integration includes dedicated AHB-resident Ethernet MAC with MII/RMII, two independent CAN controllers sharing APB resources but supporting concurrent arbitration, and a unified GPDMA controller servicing SSP, I2S, SD/MMC, and memory-to-memory transfers-enabling synchronized multi-interface data movement without CPU intervention.

FAQ

What is the maximum operating frequency of the LPC2460FET208?

The LPC2460FET208 operates at up to 72 MHz using its on-chip PLL, which can be driven from the main oscillator (1–25 MHz crystal), internal 4 MHz RC oscillator, or RTC oscillator. This frequency is validated across the full industrial temperature range (−40 °C to +85 °C) and supports deterministic real-time execution of Ethernet and CAN stacks without throttling.

Does the LPC2460FET208 include on-chip flash memory?

No, the LPC2460FET208 is a flashless microcontroller. It relies on external memory via its External Memory Controller (EMC) for program storage-supporting SDRAM, NOR/NAND flash, and SRAM. Firmware must be loaded at boot via ISP (In-System Programming) over UART, USB, or CAN, or executed directly from external memory mapped into the ARM address space.

How many CAN interfaces does the LPC2460FET208 support?

The LPC2460FET208 integrates two independent Controller Area Network (CAN) 2.0B controllers, each with full message object buffers, acceptance filtering, and automatic retransmission. Both CAN channels operate concurrently and are accessible via dedicated APB peripherals-confirmed in Table 2 of the official datasheet and functional block diagram (Figure 1).

What package type is used for the LPC2460FET208?

The LPC2460FET208 uses a TFBGA208 package (SOT950-1): 208-ball thin fine-pitch BGA with 15 × 15 × 0.7 mm body and 0.65 mm ball pitch. This package is distinct from the LQFP208 variant (LPC2460FBD208) and requires specific PCB layout rules for thermal vias, solder mask defined pads, and controlled impedance routing for high-speed signals like ENET and USB.

Can the LPC2460FET208 operate in low-power modes with Ethernet active?

No-Ethernet MAC operation requires the main AHB clock domain to be active, which prevents entry into Power-down or Deep power-down modes. The LPC2460FET208 supports Idle and Sleep modes with Ethernet enabled, but full power-down requires disabling the Ethernet controller and its 16 kB SRAM buffer. Wake-up from Sleep mode is possible via Ethernet wake-on-LAN (WOL) interrupt, as documented in Section 2.12 of the datasheet.
