Product details
Overview
LPC2388FBD144K from NXP Semiconductors is a 32-bit ARM7TDMI-S microcontroller operating at up to 72 MHz, integrating 512 kB flash, 64 kB on-chip SRAM, dual CAN channels, 10/100 Ethernet MAC with RMII, USB 2.0 device/host/OTG, and 10-bit ADC/DAC. It serves as a communication gateway controller in industrial protocol converters requiring concurrent serial interface management.
For engineers reviewing the LPC2388FBD144K datasheet, LPC2388FBD144K pinout, LPC2388FBD144K application, or LPC2388FBD144K equivalent, key selection factors include its dual-AHB architecture enabling simultaneous Ethernet DMA, USB DMA, and flash execution; 104 GPIO with edge/level interrupt support; and 144-pin LQFP package with RMII, USB PHY, and SD/MMC interface routing capability.
Technical Context
The LPC2388FBD144K implements an ARM7TDMI-S core with real-time emulation and a dual Advanced High-performance Bus (AHB) system-separating Ethernet and USB DMA traffic from CPU instruction fetches to eliminate bus contention. Its memory subsystem includes 512 kB flash on the ARM local bus and three dedicated SRAM blocks: 64 kB for CPU access, 16 kB for Ethernet, and 16 kB shared by USB and general-purpose DMA.
Peripheral integration follows a multi-bus hierarchy: Ethernet MAC and USB reside on independent AHB segments; GPDMA services SSP, I2S, and SD/MMC; and APB hosts timers, ADC, DAC, VIC, and RTC. Pin multiplexing via the Pin Connect Block enables dynamic assignment of UART, CAN, I2C, SPI, SSP, I2S, and trace signals across Port 0–3.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LPC2478FBD208 | 208-pin LQFP, 512 kB flash, 96 kB SRAM, same peripheral set plus LCD controller and external SDRAM interface | Requires larger PCB footprint and additional SDRAM; suited for HMI-integrated gateways | Select when display interface or >64 kB contiguous RAM is required; not drop-in compatible due to pin count and layout |

FAQ
What is the maximum operating frequency of the LPC2388FBD144K?
The LPC2388FBD144K operates at a maximum CPU clock frequency of 72 MHz, achieved via its on-chip PLL driven by the main oscillator, internal RC oscillator, or RTC oscillator. This frequency applies to ARM and Thumb instruction execution and is validated across the full −40 °C to +85 °C industrial temperature range specified for the LPC2388FBD144K.
Does the LPC2388FBD144K include an integrated USB physical layer?
Yes, the LPC2388FBD144K integrates a full-speed USB 2.0 transceiver with on-chip PHY, supporting device, host, and OTG operation without external components. The USB port 1 and port 2 I/O pins (e.g., P0[29]/USB_D+1) are directly connected to the internal PHY, enabling plug-and-play connectivity for LPC2388FBD144K-based designs.
How much SRAM is allocated specifically for Ethernet operations in the LPC2388FBD144K?
The LPC2388FBD144K allocates 16 kB of dedicated SRAM for Ethernet interface use, accessible exclusively by the Ethernet MAC DMA controller. This memory is physically isolated from the 64 kB CPU local bus SRAM and can also be reconfigured as general-purpose SRAM if Ethernet functionality is unused in the LPC2388FBD144K application.
What peripheral interfaces does the LPC2388FBD144K support for connecting SD or MMC cards?
The LPC2388FBD144K supports SD/MMC cards via a dedicated SD/MMC memory card interface with six signals: MCICLK, MCICMD, MCIDAT[3:0]. These are mapped to pins P0[19], P0[20], and P0[22]–P0[25], enabling direct connection to compliant cards without external level shifters or controllers in the LPC2388FBD144K design.
Can the LPC2388FBD144K retain data during main power loss?
Yes, the LPC2388FBD144K includes 2 kB of battery-powered SRAM tied to the RTC power domain. When supplied via the VBAT pin, this memory retains data even when the main 3.3 V supply is removed-enabling persistent storage of calibration values, event logs, or security keys in LPC2388FBD144K-based systems with backup power.
