NXP Semiconductors LPC2387FBD100,551

Overview

LPC2387FBD100 from NXP Semiconductors is a 32-bit ARM7TDMI-S microcontroller operating at up to 72 MHz, integrating 512 kB flash, 64 kB local bus SRAM, dual CAN channels, 10/100 Ethernet MAC with RMII, USB 2.0 device/host/OTG with on-chip PHY, and 10-bit ADC/DAC. It serves as a communication gateway controller in industrial protocol conversion systems requiring concurrent high-speed serial interfaces and deterministic real-time response.

For engineers reviewing the LPC2387FBD100 datasheet, LPC2387FBD100 pinout, LPC2387FBD100 application, or LPC2387FBD100 equivalent, key selection considerations include its dual AHB architecture enabling simultaneous Ethernet DMA, USB DMA, and flash execution; 70 GPIO pins with 12 external interrupt-capable inputs; and support for RMII, SD/MMC, I2S, and three I²C buses - all in a 100-pin LQFP package.

Technical Context

The LPC2387FBD100 implements an ARM7TDMI-S core with real-time emulation and a 128-bit wide memory interface, enabling full 32-bit instruction execution at 72 MHz while delivering up to 30% higher ISR performance than Thumb mode. Its dual Advanced High-performance Bus (AHB) system isolates Ethernet and USB DMA traffic from CPU program execution, eliminating bus contention.

Peripheral integration includes a dedicated AHB-resident Ethernet MAC with RMII support, USB 2.0 OTG with integrated PHY and 4 kB endpoint RAM, four UARTs with fractional baud rate generation, two independent CAN controllers, and a General Purpose DMA controller servicing SSP, I²S, and SD/MMC interfaces - all coordinated via an Advanced Vectored Interrupt Controller supporting 32 vectored IRQs.

FAQ

What is the maximum operating frequency of the LPC2387FBD100?

The LPC2387FBD100 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 is sustained across the full industrial temperature range (−40 °C to +85 °C) and supports deterministic real-time execution of Ethernet and USB protocol stacks without throttling.

Does the LPC2387FBD100 include an integrated USB transceiver?

Yes, the LPC2387FBD100 integrates a full-speed USB 2.0 transceiver with on-chip PHY, supporting device, host, and OTG roles. It requires no external USB transceiver IC and provides dedicated pins (P0[29]/P0[30]) for D+/D−, along with USB_PPWR1, USB_RCV1, and USB_INT1 signals for OTG functionality - all managed natively by the LPC2387FBD100's USB controller.

How many CAN interfaces does the LPC2387FBD100 support, and what version?

The LPC2387FBD100 supports two independent CAN 2.0B controllers, each with full CAN protocol compliance including identifier masking, message filtering, and error handling. CAN1 and CAN2 are implemented as separate peripheral blocks with dedicated receive (RD1/RD2) and transmit (TD1/TD2) pins mapped to Port 0, enabling simultaneous operation on two distinct CAN networks.

What type of Ethernet interface is provided on the LPC2387FBD100?

The LPC2387FBD100 features a 10/100 Ethernet MAC with Reduced Media Independent Interface (RMII), requiring only eight external signals (TXD0/TXD1/TX_EN/CRS/RXD0/RXD1/RX_ER/REF_CLK). It does not include a physical layer (PHY); an external RMII-compliant PHY (e.g., DP83848) must be used, but the MAC handles all frame assembly, checksum calculation, and DMA-managed buffer management internally.

Is the LPC2387FBD100 pin-compatible with other members of the LPC2300 family?

No, the LPC2387FBD100 is not pin-compatible with other LPC2300 variants such as the LPC2368 or LPC2378, due to differences in peripheral mapping, pinmux configuration, and package-specific signals like RSTOUT (available only in the LQFP100 variant). While functional overlap exists in flash size and peripheral sets, PCB layout must be designed specifically for the LPC2387FBD100's 100-pin LQFP pinout and signal assignments.
