Product details
Overview
LPC1788FBD144,551 from NXP Semiconductors is a 32-bit ARM Cortex-M3 microcontroller designed for high-integration embedded systems requiring Ethernet, USB Device/Host/OTG, and LCD control. It operates at up to 120 MHz, integrates 512 kB flash, 96 kB SRAM, and supports 109 GPIO pins in an LQFP144 package. It is deployed in industrial automation controllers and medical scanning equipment.
For engineers reviewing the LPC1788FBD144,551 datasheet, LPC1788FBD144,551 pinout, LPC1788FBD144,551 application, or LPC1788FBD144,551 equivalent, key selection criteria include its dual-CAN interface, 8-channel 12-bit ADC with DMA support, 10-bit DAC, and EMC support for SDRAM up to 80 MHz - all critical for real-time motor control and human-machine interface designs.
Technical Context
The LPC1788FBD144,551 implements a Harvard-architecture ARM Cortex-M3 core with 3-stage pipeline, integrated MPU supporting eight memory regions, and NVIC for deterministic interrupt handling. Its multilayer AHB matrix enables concurrent access by CPU, Ethernet MAC, USB controller, and GPDMA without arbitration delay unless accessing the same slave.
It features dedicated peripheral SRAM blocks (2 × 16 kB) accessible via independent paths for DMA offloading, a flash accelerator enabling zero-wait-state execution at 120 MHz, and a split APB bus with write buffering to reduce CPU stalls during peripheral writes.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LPC1778FBD144,551 | No Ethernet MAC; identical flash/SRAM/peripherals except missing Ethernet block. | Suitable for cost-sensitive CAN/USB-only edge nodes where LAN connectivity is unnecessary. | Select when Ethernet is excluded from system architecture to reduce BOM cost and simplify EMI filtering. |
| LPC1788FBD208,551 | 208-pin LQFP package; adds 56 extra GPIO, full 32-bit EMC bus width, and LCD interface pins not present in LQFP144 variant. | Required for designs needing >109 GPIO or full-resolution TFT display support (e.g., industrial HMIs). | Choose only if additional I/O or LCD pixel bandwidth justifies larger footprint and higher pin-count routing complexity. |
Compared with LPC1778FBD144,551, the LPC1788FBD144,551 adds Ethernet MAC and retains identical USB/CAN/ADC capabilities; versus LPC1788FBD208,551, it trades 56 GPIO and full EMC width for compact LQFP144 layout - making it optimal for space-constrained Ethernet-enabled controllers.

FAQ
What is the maximum operating frequency of the LPC1788FBD144,551?
The LPC1788FBD144,551 operates at a maximum CPU frequency of 120 MHz, achieved using either the on-chip PLL driven by the main oscillator (1–25 MHz crystal) or the internal 12 MHz RC oscillator trimmed to ±1% accuracy. This frequency is sustained with zero-wait-state execution from flash memory due to the integrated flash accelerator.
Does the LPC1788FBD144,551 support Ethernet connectivity?
Yes, the LPC1788FBD144,551 includes a full Ethernet MAC with MII/RMII interface and associated DMA controller, located on an independent AHB bus. It supports IEEE 802.3-compliant 10/100 Mbps operation and is fully functional in the LQFP144 package - confirmed in Table 2 of the official datasheet.
How many GPIO pins are available on the LPC1788FBD144,551?
The LPC1788FBD144,551 provides 109 general-purpose I/O pins, as specified in Table 2 for the LQFP144 package variant. All GPIOs are 5 V tolerant (except ADC/DAC pins), support configurable pull-up/down resistors, open-drain mode, and Cortex-M3 bit-banding for atomic register access.
What analog peripherals does the LPC1788FBD144,551 integrate?
The LPC1788FBD144,551 integrates an 8-channel 12-bit ADC with up to 400 kHz conversion rate and a 10-bit DAC with dedicated conversion timer. Both peripherals support GPDMA transfers, and the ADC includes multiple result registers for efficient sampling in real-time control applications.
Is the LPC1788FBD144,551 pin-compatible with earlier NXP microcontrollers?
The LPC1788FBD144,551 pinout is designed for functional compatibility with the LPC23xx and LPC24xx families, but not pin-to-pin compatible. Pin function mapping differs significantly due to architectural enhancements (e.g., Cortex-M3 NVIC, AHB/APB hierarchy), requiring PCB redesign despite shared package outline and I/O count alignment.
