Overview
LPC2378FBD144K from NXP Semiconductors is a 32-bit ARM7TDMI-S microcontroller operating at up to 72 MHz, integrating 512 kB flash, 32 kB local SRAM, 16 kB Ethernet SRAM, 8 kB USB/general-purpose SRAM, and 2 kB battery-backed RTC SRAM. It features dual CAN channels, USB 2.0 full-speed device with on-chip PHY, 10/100 Ethernet MAC with RMII, four UARTs, three I²C interfaces, two SSPs, SPI, I²S, SD/MMC, 10-bit ADC (8-channel), 10-bit DAC, PWM, and 104 GPIO - enabling use in industrial protocol gateways and embedded communication systems.
For engineers reviewing the LPC2378FBD144K datasheet, LPC2378FBD144K pinout, LPC2378FBD144K application, or LPC2378FBD144K equivalent, key selection considerations include dual-CAN support, integrated USB+Ethernet+SD/MMC peripherals, 72 MHz real-time execution capability, AHB-based DMA concurrency for Ethernet/USB/memory access, and 144-pin LQFP packaging with extensive peripheral multiplexing.
Technical Context
The LPC2378FBD144K implements an ARM7TDMI-S core with dual Advanced High-performance Bus (AHB) subsystems enabling simultaneous Ethernet DMA, USB DMA, and flash execution without bus contention. Its AHB-to-APB bridge connects peripherals including VIC, GPDMA, timers, ADC/DAC, and serial interfaces.
Peripheral integration includes dedicated AHB-resident Ethernet MAC and USB controllers, each with associated DMA engines; a General Purpose DMA controller supporting SSP, I²S, and SD/MMC; and a versatile pin connect block allowing dynamic assignment of functions like CAN1/CAN2, USB D+/D−, RMII signals, and I²S clock/data lines across multiple port pins.

FAQ
What is the maximum operating frequency of the LPC2378FBD144K?
The LPC2378FBD144K 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 both ARM and Thumb instruction sets, with ARM mode delivering higher performance for interrupt service routines and DSP algorithms compared to Thumb mode.
Does the LPC2378FBD144K include an integrated USB transceiver?
Yes, the LPC2378FBD144K integrates a full-speed USB 2.0 device transceiver with on-chip PHY, eliminating the need for external USB transceiver components. It supports standard USB device classes and includes 4 kB of dedicated endpoint RAM for descriptor and data buffering - confirmed in the official NXP LPC2377/78 datasheet section 2.2.
How many CAN interfaces does the LPC2378FBD144K support?
The LPC2378FBD144K supports two independent CAN 2.0B controllers (CAN1 and CAN2), each with dedicated RX/TX pins (e.g., P0[0]/P0[1] for CAN1; P0[4]/P0[5] for CAN2). This dual-CAN capability is explicitly differentiated from the LPC2377 variant in Table 2 of the NXP datasheet and enables simultaneous multi-bus automotive or industrial network communication.
What types of memory are included on the LPC2378FBD144K die?
The LPC2378FBD144K integrates 512 kB of on-chip flash memory for program storage, 32 kB of local bus SRAM for high-speed CPU access, 16 kB of dedicated Ethernet SRAM, 8 kB of USB/general-purpose SRAM accessible by DMA, and 2 kB of battery-powered SRAM for RTC-backed data retention - all detailed in Section 2.2 and Table 2 of the NXP LPC2377/78 datasheet.
Is the LPC2378FBD144K pin-compatible with the LPC2377FBD144?
No, the LPC2378FBD144K is not fully pin-compatible with the LPC2377FBD144. While both share the LQFP144 package and core peripheral set, the LPC2378FBD144K exposes additional signals including USB_D+1/USB_D−1, USB_D+2/USB_D−2, CAN2_RX/CAN2_TX, and USB_CONNECT1/USB_CONNECT2 - requiring distinct PCB layout and pin assignment per the NXP pin description tables.
