Product details
Overview
LPC2470FET208,551 from NXP Semiconductors is a flashless 32-bit ARM7TDMI-S microcontroller operating at up to 72 MHz, featuring 98 kB on-chip SRAM (64 kB local, 16 kB Ethernet, 16 kB DMA, 2 kB RTC-backed), dual CAN channels, 10/100 Ethernet MAC with MII/RMII, and USB 2.0 full-speed device/host/OTG controller - deployed in industrial control panels requiring real-time I/O, deterministic interrupt response, and integrated LCD graphics.
For engineers reviewing the LPC2470FET208,551 datasheet, LPC2470FET208,551 pinout, LPC2470FET208,551 application, or LPC2470FET208,551 equivalent, key selection criteria include TFBGA208 package compatibility, 160 GPIO with VIC-interrupt mapping, dual AHB bus arbitration for concurrent Ethernet/USB DMA, and RTC-powered 2 kB SRAM retention during deep power-down.
Technical Context
The LPC2470FET208,551 implements an ARM7TDMI-S core with JTAG and embedded trace support, executing both 32-bit ARM and 16-bit Thumb instructions. Its dual AHB system isolates Ethernet and USB DMA traffic to prevent bus contention while enabling simultaneous high-bandwidth peripheral operation.
Hardware peripherals are mapped across two independent power domains (VDD(3V3) and VDD(DCDC)(3V3)), allowing selective shutdown of unused subsystems. Clocking includes a 4 MHz ±1 % internal RC oscillator, programmable PLL, and external crystal support (1–25 MHz), with individual peripheral clock dividers reducing active power by 20–30 %.
Key Specifications

|---|---|
| CPU Core | ARM7TDMI-S, 32-bit/16-bit Thumb, up to 72 MHz - enables deterministic real-time execution with legacy ARM7 toolchain compatibility. |
| Total SRAM | 98 kB: 64 kB local bus SRAM (CPU-optimized), 16 kB Ethernet buffer, 16 kB general-purpose DMA, 2 kB RTC-retained - eliminates need for external RAM in many embedded designs. |
| Communication Interfaces | 1× 10/100 Ethernet MAC (MII/RMII), 2× CAN 2.0B, 4× UART (with FIFO/IRDA/modem I/O), 3× I²C, 2× SSP, 1× SPI, 1× I²S, 1× SD/MMC - supports multi-protocol industrial fieldbus and media connectivity. |

| Package & Power | TFBGA208 (15×15×0.7 mm), −40 °C to +85 °C; single 3.3 V supply (3.0–3.6 V); four low-power modes (idle/sleep/power-down/deep power-down) - suitable for space-constrained industrial and portable applications. |
| Interrupt & I/O | Advanced Vectored Interrupt Controller (VIC) with 32 vectored IRQs; 160 GPIO pins (64 mapped to VIC edge-triggered interrupts); configurable pull-up/down - delivers responsive, prioritized event handling for sensor and actuator interfaces. |
Pinout & Package

|---|---|---|
| P0[0]/RD1/TXD3/SDA1 | CAN1 RX / UART3 TX / I²C1 data | Multi-function pin supporting critical fieldbus (CAN), serial debug (UART3), and sensor interface (I²C1) - requires pin-select configuration via Pin Connect Block. |
| P1[0]/ENET_TXD0 | Ethernet transmit data bit 0 | Dedicated RMII/MII signal routed to external PHY; must be impedance-controlled (50 Ω) and length-matched with other ENET signals. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LPC2468FET208,551 | Omits LCD controller and 16 kB Ethernet SRAM; retains same CPU, CAN, USB, and peripheral set. | Suitable where display is handled externally or not required; lower cost for pure connectivity/control use cases. | Select when LCD functionality is unnecessary and BOM cost optimization is prioritized over integration. |
| LPC2378FBD208,551 | LQFP208 package (vs. TFBGA208); identical core/peripherals but lacks USB OTG and has reduced SRAM allocation (no dedicated Ethernet buffer). | Better suited for prototyping or applications requiring easier rework; limited to USB device-only mode. | Choose for design flexibility in early development or where USB host/OTG capability is not needed. |
Compared with LPC2468FET208,551 and LPC2378FBD208,551, the LPC2470FET208,551 uniquely integrates LCD controller + dedicated display DMA and dual AHB buses - making it the only option among the three capable of concurrent high-bandwidth Ethernet and USB OTG operation with local graphics rendering.

FAQ
What is the maximum operating frequency of the LPC2470FET208,551?
The LPC2470FET208,551 operates at up to 72 MHz using its on-chip PLL, which can be driven by the internal 4 MHz RC oscillator, external crystal (1–25 MHz), or RTC oscillator. This frequency is confirmed in the official NXP datasheet Rev. 4.2 and applies directly to the LPC2470FET208,551 variant in TFBGA208 packaging.
Does the LPC2470FET208,551 include on-chip flash memory?
No, the LPC2470FET208,551 is a flashless microcontroller. It relies on external non-volatile memory (e.g., NOR flash via EMC) for program storage. All variants of the LPC2470, including LPC2470FET208,551, omit on-chip flash to reduce cost and power while maximizing SRAM resources (98 kB total).
How does the dual AHB architecture benefit the LPC2470FET208,551 in real-time applications?
The dual AHB architecture in the LPC2470FET208,551 separates Ethernet and USB DMA traffic onto independent buses, preventing contention and ensuring deterministic latency for time-critical operations. This allows concurrent high-throughput data transfer on both interfaces - a capability verified in the LPC2470FET208,551 datasheet block diagram and timing specifications.
What is the function of the 2 kB RTC-powered SRAM in the LPC2470FET208,551?
That 2 kB SRAM in the LPC2470FET208,551 is powered from the RTC domain (VBAT pin), retaining data during main power loss or deep power-down mode. It is used for storing critical state information like calibration constants or fault logs - a feature explicitly documented for the LPC2470FET208,551 in Table 2 and Section 2.2 of the datasheet.
Is the LPC2470FET208,551 pin-compatible with the LPC2470FBD208?
No, the LPC2470FET208,551 (TFBGA208) and LPC2470FBD208 (LQFP208) share identical electrical functionality and register mapping but differ in physical pinout and package dimensions. Their ball/pad assignments are distinct - confirmed by Figures 2 and 3 and Table 3 in the LPC2470 datasheet - so PCB layout is not interchangeable.
