Product details
Overview
LPC2460FET208Y from NXP Semiconductors is a flashless 32-bit ARM7TDMI-S microcontroller optimized for industrial communication gateways and protocol converters. It operates at up to 72 MHz, integrates dual CAN channels, a 10/100 Ethernet MAC with MII/RMII, USB 2.0 full-speed device/host/OTG, and 98 kB on-chip SRAM (including 16 kB Ethernet buffer and 16 kB general-purpose DMA RAM). Its TFBGA208 package supports high-density routing in space-constrained embedded systems.
For engineers reviewing the LPC2460FET208Y datasheet, LPC2460FET208Y pinout, LPC2460FET208Y application, or LPC2460FET208Y equivalent, key selection considerations include Ethernet + dual CAN coexistence, USB OTG capability with integrated PHY, 160 GPIOs with VIC-interrupt mapping, and support for external SDRAM via EMC - all within a single-chip, no-flash architecture requiring external program memory.
Technical Context
The LPC2460FET208Y implements an ARM7TDMI-S core with dual AHB buses enabling concurrent Ethernet DMA and USB DMA without bus contention. Its memory subsystem includes 64 kB local SRAM, 16 kB Ethernet-dedicated SRAM, 16 kB GP/USB-accessible SRAM, and 2 kB RTC-powered battery RAM - all accessible via configurable clock dividers for fine-grained power control.
Peripheral integration centers on real-time communication: two independent CAN controllers (CAN1/CAN2), a full-featured Ethernet MAC with MII/RMII physical layer interface, four UARTs (one with IrDA, one with modem I/O), three I²C interfaces (I²C0 open-drain), two SSPs, SPI, I²S, SD/MMC, 10-bit ADC (8-channel), 10-bit DAC, and dual PWM units supporting three-phase motor control.

FAQ
What distinguishes LPC2460FET208Y from the LPC2420 variant?
The LPC2460FET208Y includes Ethernet MAC with MII/RMII interface and dual CAN channels, while the LPC2420 omits both. The LPC2460FET208Y also provides 98 kB total SRAM (vs. 82 kB in LPC2420), with dedicated 16 kB Ethernet buffer and dual AHB buses enabling concurrent Ethernet and USB DMA - features absent in LPC2420FET208Y.
Does LPC2460FET208Y require external flash memory to operate?
Yes, the LPC2460FET208Y is flashless and requires external non-volatile memory (e.g., NOR flash via EMC or SPI flash) for program storage. Boot configuration pins select between UART, USB, or external memory boot modes. The 98 kB on-chip SRAM is used exclusively for runtime code and data execution.
Can LPC2460FET208Y support both USB device and host functions simultaneously?
No - the USB 2.0 controller in LPC2460FET208Y operates in device, host, or OTG mode, but not concurrently. OTG mode allows dynamic role switching under software control using the internal transceiver and VBUS detection, but only one USB stack (device or host) runs at a time.
What power domains does LPC2460FET208Y implement for low-power operation?
The LPC2460FET208Y uses two independent power domains: one for digital logic (VDD(3V3)) and one for RTC and battery RAM (VBAT). This enables deep power-down mode where only the 2 kB RTC SRAM remains powered, retaining critical state while reducing system current to microamp levels.
Is the TFBGA208 package of LPC2460FET208Y compatible with standard PCB assembly processes?
Yes - the LPC2460FET208Y in TFBGA208 (SOT950-1, 0.65 mm pitch, 15 × 15 mm body) is compatible with industry-standard reflow soldering and automated optical inspection (AOI). Its 0.7 mm height and thermal pad design support reliable thermal dissipation in high-density industrial layouts.
