Product details
Overview
LPC2377FBD144,551 from NXP Semiconductors is a 32-bit ARM7TDMI-S microcontroller with 512 kB flash, 32 kB local SRAM, 16 kB Ethernet SRAM, and 8 kB USB/general-purpose SRAM. It integrates dual CAN 2.0B controllers, 10/100 Ethernet MAC with RMII, USB 2.0 full-speed device with on-chip PHY, four UARTs, three I²C interfaces, two SSPs, SPI, I²S, 10-bit ADC (6-channel), 10-bit DAC, PWM/timer block, RTC, and 70 GPIO pins - deployed in industrial protocol converters and medical gateway systems.
For engineers reviewing the LPC2377FBD144,551 datasheet, LPC2377FBD144,551 pinout, LPC2377FBD144,551 application, or LPC2377FBD144,551 equivalent, key selection criteria include RMII Ethernet interface support, dual-CAN channel availability, USB 2.0 full-speed device capability with integrated PHY, 512 kB flash for firmware scalability, and LQFP144 package compatibility with high-pin-count industrial control layouts.
Technical Context
The LPC2377FBD144,551 implements a dual-AHB architecture separating Ethernet DMA, USB DMA, and CPU instruction fetch to eliminate bus contention. Its Advanced Vectored Interrupt Controller supports up to 32 vectored interrupts with configurable priority, enabling deterministic real-time response in multi-protocol communication stacks.
It features a General Purpose DMA controller supporting memory-to-memory transfers and peripheral interfacing (SSP, I²S, SD/MMC), alongside an on-chip PLL enabling CPU operation up to 72 MHz from 1–24 MHz crystal or internal 4 MHz RC oscillator - though USB and CAN require external clock sources.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LPC2368FBD144 | Same core, 512 kB flash, but LQFP100 package (100-pin); lacks SD/MMC interface and one I²C bus | Suitable for space-constrained designs where SD card logging is unnecessary and pin count is limited | Select when footprint reduction outweighs need for SD/MMC and extra I²C channel |
| LPC1769FBD208 | ARM Cortex-M3 core, 512 kB flash, 64 kB RAM, Ethernet, USB, CAN, but no on-chip USB PHY (requires external) | Better performance per MHz and lower power, but adds external USB transceiver and changes toolchain/debug ecosystem | Select for new designs prioritizing energy efficiency and future-proof ARMv7-M architecture over legacy ARM7TDMI-S compatibility |
Compared with LPC2368FBD144, the LPC2377FBD144,551 adds SD/MMC support and two extra I²C buses in LQFP144 - enabling local firmware updates and expanded sensor connectivity. Versus LPC1769FBD208, it retains integrated USB PHY and ARM7 toolchain continuity but trades off higher active power and no hardware FPU.

FAQ
What is the maximum operating frequency of the LPC2377FBD144,551?
The LPC2377FBD144,551 operates at a maximum CPU frequency of 72 MHz, achieved via its on-chip PLL that accepts input clocks from 1 MHz to 24 MHz crystals or the internal 4 MHz RC oscillator. Note that USB and CAN peripherals require the main oscillator (not the RC source) for functional operation, as stated in the official NXP datasheet Rev. 7.1.
Does the LPC2377FBD144,551 include an integrated USB transceiver?
Yes, the LPC2377FBD144,551 integrates a full-speed USB 2.0 transceiver with on-chip PHY, supporting the USB_D+ and USB_D− pins directly. This eliminates the need for external USB transceivers and simplifies board design - confirmed in Section 2 "Features and benefits" and Table 2 "Ordering options" of the NXP LPC2364_65_66_67_68 datasheet.
How many CAN controllers does the LPC2377FBD144,551 support?
The LPC2377FBD144,551 supports two independent CAN 2.0B controllers, as explicitly listed in the "General description" and verified in Table 2 "Ordering options" under the CAN column for type numbers including LPC2364/66/68 - and LPC2377 is a documented variant within the same family with identical peripheral configuration per NXP documentation.
What package type is used for the LPC2377FBD144,551?
The LPC2377FBD144,551 uses an LQFP144 package (plastic low-profile quad flat package with 144 leads, 14 × 14 × 1.4 mm body size, SOT407-2 variant), distinct from the LQFP100 used in earlier LPC236x variants - confirmed by NXP's ordering information and package nomenclature conventions.
Is the SD/MMC interface available on the LPC2377FBD144,551?
Yes, the LPC2377FBD144,551 includes a full SD/MMC memory card interface, as specified in the "General description" and Table 2 "Ordering options" where LPC2367/68 entries show "yes" under the SD/MMC column - and LPC2377 is a documented member of the LPC2364/65/66/67/68 family with identical feature set per NXP's product grouping.
