Product details
Overview
LPC1767FBD100K 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, and dual CAN 2.0B controllers-designed for industrial networking and motor control systems requiring real-time I/O, deterministic timing, and protocol stack integration.
For engineers reviewing the LPC1767FBD100K datasheet, LPC1767FBD100K pinout, LPC1767FBD100K application, or LPC1767FBD100K equivalent, key selection criteria include its 100 MHz CPU frequency, 70 GPIO pins with configurable open-drain mode, absence of USB Host/OTG and I2S interfaces (per Table 2), and compatibility with LPC236x pinout for legacy migration paths.
Technical Context
The LPC1767FBD100K implements an Arm Cortex-M3 core with Harvard architecture, 3-stage pipeline, and integrated Memory Protection Unit (MPU) supporting eight memory regions. Its AHB multilayer matrix enables concurrent access by CPU, GPDMA, Ethernet MAC, and USB peripherals without arbitration delay.
Peripheral subsystems include a 12-bit ADC (8-channel, 200 kHz sampling), 10-bit DAC (available on this variant), four general-purpose timers with capture/compare, motor control PWM, quadrature encoder interface, RTC with battery backup, and Wake-up Interrupt Controller (WIC) for low-power mode recovery via external interrupts or CAN activity.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LPC1768FBD100 | Includes USB Device/Host/OTG controller and I²S interface; otherwise identical flash/SRAM/peripheral set. | Required for USB peripheral device firmware updates or audio streaming; not needed for pure CAN/Ethernet gateways. | Select LPC1768FBD100 only if USB host capability or I²S audio path is mandatory. |
| LPC1766FBD100 | Same package and pinout, but reduced flash (256 kB); retains Ethernet, dual CAN, and all analog peripherals. | Suitable for cost-sensitive applications where firmware footprint fits within 256 kB and no future feature expansion is planned. | Choose LPC1766FBD100 when BOM cost reduction is critical and code size remains under 256 kB. |
Compared with LPC1768FBD100, LPC1767FBD100K omits USB OTG and I²S to reduce silicon area and cost while retaining full Ethernet/CAN functionality; versus LPC1766FBD100, it doubles flash capacity to 512 kB for complex protocol stacks and field-upgradable firmware.

FAQ
What is the maximum operating frequency of the LPC1767FBD100K?
The LPC1767FBD100K operates at a maximum CPU frequency of 100 MHz, achieved via internal PLL driven by the main oscillator, internal RC oscillator, or RTC oscillator. This frequency is confirmed in Table 2 of the official NXP datasheet Rev. 9.10 and enables deterministic execution of real-time control algorithms in motor drive and industrial automation applications. The LPC1767FBD100K does not support the 120 MHz mode found in the LPC1769 variant.
Does the LPC1767FBD100K include USB Host/OTG functionality?
No, the LPC1767FBD100K does not include USB Host/OTG functionality. As specified in Table 2 of the NXP datasheet Rev. 9.10, USB capability is marked "no" for this part number, distinguishing it from the LPC1768FBD100 and LPC1769FBD100 variants. The LPC1767FBD100K retains USB Device-only mode, which supports firmware updates and HID-class peripherals but excludes host enumeration or OTG role switching.
How many CAN controllers are integrated into the LPC1767FBD100K?
The LPC1767FBD100K integrates two CAN 2.0B controllers, as explicitly stated in both the General Description section and Table 2 of the NXP datasheet Rev. 9.10. These controllers support full CAN protocol compliance, including identifier masking, message filtering, and FIFO-based transmission/reception-making the LPC1767FBD100K suitable for J1939-based vehicle diagnostics and CANopen industrial networks.
What package type is used for the LPC1767FBD100K?
The LPC1767FBD100K uses the LQFP100 package (plastic low-profile quad flat package with 100 leads, body size 14 mm × 14 mm × 1.4 mm, SOT407-1). This package is pin-compatible with the LPC236x series and supports standard surface-mount assembly processes, including reflow soldering and automated optical inspection. Pin configuration details are provided in Figure 2 and Table 5 of the NXP datasheet.
Is the LPC1767FBD100K pin-compatible with the LPC236x microcontroller family?
Yes, the LPC1767FBD100K is pin-compatible with the 100-pin LPC236x ARM7-based microcontroller series, as confirmed in the General Description section of the NXP datasheet Rev. 9.10. This compatibility allows direct PCB-level replacement in existing designs, preserving layout, routing, and external circuitry while upgrading to the higher-performance ARM Cortex-M3 architecture, enhanced debug features, and expanded peripheral set of the LPC1767FBD100K.
