Product details
Overview
LPC1767FBD100,551 from NXP Semiconductors is a 32-bit ARM Cortex-M3 microcontroller in LQFP100 package, operating at up to 100 MHz with 512 kB flash, 64 kB SRAM, Ethernet MAC, dual CAN 2.0B controllers, and 70 GPIOs - deployed in industrial networking gateways requiring deterministic real-time control and protocol bridging.
For engineers reviewing the LPC1767FBD100,551 datasheet, LPC1767FBD100,551 pinout, LPC1767FBD100,551 application, or LPC1767FBD100,551 equivalent, key selection criteria include absence of USB Host/OTG and I2S interfaces (vs. LPC1768), confirmed Ethernet + dual CAN support, and pin-compatibility with LPC236x Arm7 series for legacy migration paths.
Technical Context
The LPC1767FBD100,551 implements a Harvard-architecture Cortex-M3 core with 3-stage pipeline, integrated MPU supporting eight memory regions, and NVIC for low-latency interrupt handling. Its AHB multilayer matrix enables concurrent CPU, DMA, Ethernet, and USB access without arbitration delay - though USB functionality is omitted in this variant.
Peripheral interconnect uses split APB buses for high-throughput CPU-DMA transfers. The device includes dedicated GPDMA channels for UART, ADC, DAC, SSP, and I2S (not present on LPC1767), and supports fractional baud rate generation across four UARTs - one with RS-485/EIA-485 and another with IrDA capability.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LPC1768FBD100/CP32 | Includes USB 2.0 Device/Host/OTG controller and I2S interface; same flash/SRAM/Ethernet/CAN specs. | Required for designs needing USB peripheral connectivity (e.g., firmware update via USB mass storage) or digital audio I/O. | Select LPC1768 when USB or I2S functionality is mandatory; LPC1767 remains optimal for cost-sensitive Ethernet+CAN-only systems. |
| LPC1766FBD100,551 | Same package and peripherals as LPC1767 but with 256 kB flash and identical 64 kB SRAM. | Suitable for applications with smaller firmware footprint where Ethernet+CAN+UART/I²C suffices without full 512 kB code space. | Choose LPC1766 to reduce cost while retaining identical peripheral set and pinout - ideal for scaled-down gateway variants. |
Compared with LPC1768FBD100/CP32, LPC1767FBD100,551 removes USB/I2S to lower cost and power, while matching Ethernet/CAN performance; versus LPC1766FBD100,551, it doubles flash capacity for complex protocol stacks without changing layout or firmware architecture.

FAQ
Does LPC1767FBD100,551 support USB functionality?
No, LPC1767FBD100,551 does not include USB Device/Host/OTG controller or on-chip PHY. This is explicitly confirmed in Table 2 of the NXP datasheet Rev. 9.10, which lists "no" under USB for LPC1767FBD100. Pins P0[29] and P0[30] are reserved but unconnected internally. For USB capability, select LPC1768FBD100/CP32 instead.
What is the maximum operating frequency of LPC1767FBD100,551?
The LPC1767FBD100,551 operates at a maximum CPU frequency of 100 MHz, as specified in Table 2 and Section 1 of the NXP datasheet Rev. 9.10. This is achieved using the internal PLL driven by the main oscillator (1–25 MHz crystal) or 4 MHz internal RC oscillator, enabling deterministic real-time execution with zero wait-state flash access.
Is LPC1767FBD100,551 pin-compatible with other LPC176x devices?
Yes, LPC1767FBD100,551 is fully pin-compatible with all LQFP100-packaged LPC176x variants (e.g., LPC1768FBD100, LPC1766FBD100) and also with the legacy LPC236x Arm7 series. This allows hardware reuse across firmware variants and simplifies migration paths - confirmed in Section 1 and Table 1 of the NXP datasheet.
Does LPC1767FBD100,551 include a DAC?
Yes, LPC1767FBD100,551 includes a 10-bit Digital-to-Analog Converter (DAC) with dedicated conversion timer and DMA support, as verified in Table 2 ("yes" under DAC column) and Section 2 features list. The DAC output is available on pin P0[26] (AOUT), usable for analog reference generation or waveform synthesis.
What debug interfaces are supported by LPC1767FBD100,551?
LPC1767FBD100,551 supports standard JTAG debug interface for full boundary-scan and emulation, plus Serial Wire Debug (SWD) and Serial Wire Trace (SWO) options. The Emulation Trace Module enables non-intrusive real-time instruction tracing. Boundary Scan Description Language (BSDL) is not available for this device, per Section 2 of the NXP datasheet.
