Product details
Overview
LPC1768FBD100Y from NXP Semiconductors is a 32-bit ARM Cortex-M3 microcontroller designed for embedded control applications requiring Ethernet, USB Host/Device/OTG, dual CAN, and high-resolution analog I/O. It operates at up to 100 MHz, integrates 512 kB flash, 64 kB SRAM, 8-channel 12-bit ADC, 10-bit DAC, and 70 GPIO pins in an LQFP100 package - deployed in industrial networking gateways and motor control systems.
For engineers reviewing the LPC1768FBD100Y datasheet, LPC1768FBD100Y pinout, LPC1768FBD100Y application, or LPC1768FBD100Y equivalent, key selection criteria include its dual-CAN 2.0B support, RMII Ethernet MAC with dedicated DMA, USB 2.0 full-speed OTG capability with on-chip PHY, and pin compatibility with legacy LPC236x Arm7 devices.
Technical Context
The LPC1768FBD100Y implements a Harvard-architecture 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, GPDMA, Ethernet MAC, and USB controller without arbitration delay.
Peripheral subsystems include four UARTs with fractional baud rate generation and RS-485/IrDA support, two SSP controllers with FIFO and multi-protocol operation, three I²C-bus interfaces (one Fast-mode Plus capable), and a dedicated motor control PWM block supporting three-phase drive - all accessible via configurable pin muxing through the Pin Connect Block.

Yes, the LPC1768FBD100Y integrates a full Ethernet MAC with RMII interface, as verified in Table 2 and Section 2 "Features and benefits" of the NXP datasheet. It supports 10/100 Mbps operation and includes a dedicated DMA controller - but requires external PHY (e.g., LAN8720A) for physical layer connectivity.
Is the LPC1768FBD100Y pin-compatible with the LPC236x series?
Yes, the LPC1768FBD100Y is explicitly pin-compatible with the 100-pin LPC236x Arm7-based microcontroller series, as stated in the General Description section. This allows drop-in replacement in existing designs, preserving PCB layout while upgrading to Cortex-M3 performance, enhanced peripherals, and improved power efficiency.
What analog features does the LPC1768FBD100Y provide?
The LPC1768FBD100Y provides an 8-channel 12-bit ADC with conversion rates up to 200 kHz and a single 10-bit DAC with dedicated conversion timer and DMA support. Both are confirmed in Table 2 and Section 2 of the datasheet - enabling simultaneous sampling of multiple sensors and precise analog output control in motor or power supply applications.
Does the LPC1768FBD100Y support USB On-The-Go (OTG)?
Yes, the LPC1768FBD100Y supports USB 2.0 full-speed Device/Host/OTG functionality with an on-chip PHY, as documented in Table 2 and Section 2.
