Product details
Overview
LPC4074FBD80,551 from NXP Semiconductors is a 32-bit ARM Cortex-M4 microcontroller designed for embedded control applications requiring high integration, low power, and deterministic real-time response. It operates at up to 120 MHz, integrates 128 kB flash, 40 kB SRAM, and 2048 B EEPROM, and supports USB Device-only operation with two CAN channels, four UARTs, and an 8-channel 12-bit ADC - deployed in industrial motor drives and appliance control systems.
For engineers reviewing the LPC4074FBD80,551 datasheet, LPC4074FBD80,551 pinout, LPC4074FBD80,551 application, or LPC4074FBD80,551 equivalent, this page delivers verified technical context, package-specific pin mapping, functional alternatives, and supply-ready procurement details - all grounded in NXP's official LPC408x/7x product data sheet (Rev. 3, Jan 2017).
Technical Context
The LPC4074FBD80,551 implements an ARM Cortex-M4 core with hardware floating-point unit (FPU) disabled, Memory Protection Unit (MPU), and Nested Vectored Interrupt Controller (NVIC), executing from on-chip flash accelerated by a dedicated flash accelerator. Its multilayer AHB matrix interconnect enables concurrent CPU and DMA access without arbitration delay unless contending for the same peripheral.
Peripheral resources include a General Purpose DMA controller supporting SSP, UART, ADC, DAC, and timers; two enhanced I²C-bus interfaces (one Fast-mode Plus capable); and a Quadrature Encoder Interface (QEI) for position sensing. The device omits Ethernet MAC, LCD controller, and EMC - distinguishing it from higher-tier LPC408x variants.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | ARM Cortex-M4 @ up to 120 MHz; includes MPU and NVIC but no integrated FPU in this variant. |
| Memory | 128 kB flash (ISP/IAP-capable), 40 kB SRAM (64 kB not available), 2048 B EEPROM - sufficient for compact real-time firmware with persistent calibration storage. |
| USB Interface | USB 2.0 full-speed Device-only controller (no Host/OTG); requires external PHY for non-embedded applications. |
| Serial Peripherals | Four UARTs (fractional baud rate, FIFO, DMA support), two CAN 2.0B controllers, three I²C-bus interfaces (one supports 1 Mbit/s Fast-mode Plus). |
| Analog Functions | Eight-channel 12-bit ADC (400 kHz max sample rate), two analog comparators, no DAC - suitable for sensor monitoring but not audio playback. |
| Timers & PWM | Four general-purpose timers (eight capture inputs, ten compare outputs), two standard PWM blocks (six outputs total), no motor control PWM - adequate for multi-axis motion control without field-oriented algorithms. |
| GPIO & Power | Up to 80 GPIO pins (LQFP80 package), 5 V tolerant (except ADC/VREF pins), four low-power modes (Sleep to Deep power-down) with RTC wake-up capability. |
Pinout & Package
LPC4074FBD80,551 is housed in an LQFP80 package (12 × 12 × 1.4 mm, SOT315-1), with 80 leads arranged in quad flat configuration. All GPIO pins are multiplexed via the Pin Connect Block and support configurable pull-up/down, open-drain, and bit-band addressing.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| P0[0] | General-purpose I/O / UART3 TX / I²C1 SDA | Primary debug/communication pin; supports UART3 transmit or I²C1 data with standard pad drive (no specialized I²C current sink). |
| P0[1] | General-purpose I/O / UART3 RX / I²C1 SCL | Complements P0[0] for full-duplex UART3 or I²C1 clock/data pair; enables isolated serial diagnostics without dedicated interface pins. |
| P0[12] | General-purpose I/O / USB_PPWR2 / SSP1_MISO | USB port power enable output; also serves as SSP1 slave data input - critical for USB enumeration timing and SPI flash boot sequencing. |
| P0[14] | General-purpose I/O / USB_CONNECT2 / SSP1_SSEL | Software-controlled USB SoftConnect signal; toggles internal 1.5 kΩ pull-up to initiate host detection - eliminates need for external switch components. |
| P0[15] | General-purpose I/O / ADC0_IN[0] | Analog input channel 0 when ADC function enabled; digital I/O otherwise - requires disabling digital function before ADC use per datasheet requirement. |
Key Features
| Feature | Design Value |
|---|---|
| ARM Cortex-M4 with MPU | Enables secure partitioning of firmware tasks (e.g., safety-critical vs. user-interface code) using eight configurable memory regions. |
| Dedicated Flash Accelerator | Eliminates wait states during flash execution at 120 MHz, achieving near-SRAM code performance without external memory. |
| Quadrature Encoder Interface (QEI) | Directly monitors rotary encoder position and direction with hardware debouncing - reduces CPU load in motor feedback loops. |
| Real-Time Clock (RTC) with Event Recorder | Retains time and logs up to three external events (e.g., fault triggers) in battery-backed registers down to 2.1 V supply - supports predictive maintenance logging. |
| Windowed Watchdog Timer (WWDT) | Prevents runaway code via strict time-window reset enforcement; includes dedicated oscillator and warning interrupt - critical for fail-safe industrial controllers. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LPC4072FBD80 | 64 kB flash, 24 kB SRAM, no CAN, no QEI, no comparator - lower memory and peripheral count. | Suitable for basic sensor nodes or simple UI controllers where CAN or motor feedback is unnecessary. | Select when cost sensitivity outweighs need for CAN diagnostics or encoder-based positioning. |
| LPC4074FBD144 | Same core and memory specs, but LQFP144 package adds 64 extra GPIOs, EMC interface, and LCD controller support. | Required for designs needing external SDRAM, TFT display, or expanded I/O for multi-sensor arrays. | Choose only if additional pins or peripherals justify larger PCB footprint and higher BOM cost. |
Compared with LPC4074FBD80,551, LPC4072FBD80 reduces system capability for cost-sensitive endpoints, while LPC4074FBD144 expands scalability at the expense of package size - making LPC4074FBD80,551 the optimal balance for space-constrained, CAN-enabled embedded controllers.

FAQ
Does LPC4074FBD80,551 include a hardware floating-point unit (FPU)?
No, the LPC4074FBD80,551 variant does not integrate a hardware FPU. While the ARM Cortex-M4 core architecture supports optional FPU, NXP disables it in this specific part number - confirmed by Table 2 in the LPC408x/7x datasheet (Rev. 3). Applications requiring intensive floating-point math must use software libraries or select an FPU-enabled variant like LPC4088.
What is the maximum operating frequency of LPC4074FBD80,551?
The LPC4074FBD80,551 operates at up to 120 MHz CPU frequency, achieved via its on-chip PLL driven by either the main oscillator (1–25 MHz crystal) or the 12 MHz internal RC oscillator. This maximum is guaranteed across the full industrial temperature range (−40 °C to +85 °C) and 2.4–3.6 V supply.
Can LPC4074FBD80,551 support Ethernet or LCD interfaces?
No, LPC4074FBD80,551 excludes both Ethernet MAC and LCD controller peripherals. Table 2 explicitly lists "no" for Ethernet and LCD columns - distinguishing it from LPC4088/LPC4078 variants. Designers requiring these functions must select a higher-tier part or implement external PHY/display drivers.
How many CAN interfaces does LPC4074FBD80,551 provide?
The LPC4074FBD80,551 integrates two fully compliant CAN 2.0B controllers (CAN0 and CAN1), each with dedicated message RAM and acceptance filtering. These are accessible on P0[0]/P0[1] (CAN1) and P0[10]/P0[11] (CAN2) - enabling dual-bus diagnostics and chassis communication in automotive and industrial networks.
Is LPC4074FBD80,551 pin-compatible with other LPC40xx devices in LQFP80 package?
Yes, LPC4074FBD80,551 shares identical LQFP80 pinout with LPC4072FBD80 and LPC4074FBD80 variants. Pin assignments for power, reset, clocks, and primary peripherals (UART, CAN, I²C, ADC) are functionally aligned - allowing direct PCB reuse when upgrading memory or peripheral features within the same package footprint.
