Overview

LPC2366FBD100 from NXP Semiconductors is a 32-bit ARM7TDMI-S microcontroller operating at up to 72 MHz, featuring 256 kB flash, 32 kB local SRAM, 16 kB Ethernet SRAM, and dual CAN channels. It integrates Ethernet MAC with RMII, USB 2.0 full-speed device interface with on-chip PHY, four UARTs, three I²C interfaces, I²S, SSP, SPI, 10-bit ADC (6-channel), 10-bit DAC, and 70 GPIO pins - deployed in industrial protocol converters and embedded communication gateways.

For engineers reviewing the LPC2366FBD100 datasheet, LPC2366FBD100 pinout, LPC2366FBD100 application, or LPC2366FBD100 equivalent, key selection criteria include RMII Ethernet support, USB full-speed device capability with 4 kB endpoint RAM, dual CAN v2.0B controllers, 256 kB ISP/IAP flash, and LQFP100 package compatibility with legacy LPC23xx designs.

Technical Context

The LPC2366FBD100 implements a dual Advanced High-performance Bus (AHB) architecture enabling concurrent Ethernet DMA, USB DMA, and flash execution without bus contention. Its AHB-to-AHB bridge allows Ethernet DMA access to the secondary AHB subsystem while maintaining CPU access to flash and local SRAM.

It features an Advanced Vectored Interrupt Controller (VIC) supporting 32 vectored interrupts, a General Purpose DMA controller (GPDMA) servicing SSP, I²S, and SD/MMC peripherals, and a configurable pin-muxing system via the Pin Connect Block that enables flexible peripheral assignment across 70 GPIO pins including Port 0–2 and P3/P4 subsets.

Yes, the LPC2366FBD100 integrates a USB 2.0 full-speed device controller with on-chip PHY and 4 kB of dedicated endpoint RAM. It supports control, interrupt, bulk, and isochronous transfer types. The USB interface is accessible via pins P0[29]/USB_D+ and P0[30]/USB_D−, and requires VBUS monitoring on P1[30] for proper enumeration.

How many CAN interfaces does the LPC2366FBD100 include?

The LPC2366FBD100 includes two CAN 2.0B-compliant controllers, designated CAN1 and CAN2. These are accessible via dedicated pins: CAN1 uses P0[0]/RD1 and P0[1]/TD1; CAN2 uses P0[4]/RD2 and P0[5]/TD2. Both controllers support standard and extended frame formats and programmable bit timing.

What type of package is used for the LPC2366FBD100?

The LPC2366FBD100 is housed in a plastic low-profile quad flat package (LQFP100) with 100 leads, 14 mm × 14 mm body size, and 0.5 mm lead pitch (SOT407-1). This RoHS-compliant package supports standard surface-mount assembly and provides mechanical and thermal characteristics suitable for industrial environments.

Is the LPC2366FBD100 pin-compatible with other LPC23xx family members?

Yes, the LPC2366FBD100 shares identical LQFP100 pinout and peripheral register mapping with LPC2364FBD100, LPC2365FBD100, LPC2367FBD100, and LPC2368FBD100.
