NXP Semiconductors LPC4076FBD144E

Overview

LPC4076FBD144E from NXP Semiconductors is a 32-bit ARM Cortex-M4 microcontroller designed for industrial and embedded control applications requiring integrated Ethernet, USB host/device/OTG, dual CAN, and motor control PWM. It operates at up to 120 MHz, integrates 256 kB flash, 80 kB SRAM, 2048 B EEPROM, and supports 8-bit EMC bus width in its LQFP144 package. It delivers real-time control in PLCs, inverters, and motor drives with hardware floating-point unit (FPU) support and RTC with battery-backed event recorder.

For engineers reviewing the LPC4076FBD144E datasheet, LPC4076FBD144E pinout, LPC4076FBD144E application, or LPC4076FBD144E equivalent, key selection criteria include its 144-pin LQFP package with 5V-tolerant GPIO, dual CAN interfaces, 12-bit ADC with 8 channels, 10-bit DAC, and absence of LCD controller - distinguishing it from LPC408x variants.

Technical Context

The LPC4076FBD144E implements an ARM Cortex-M4 core with Harvard architecture, 3-stage pipeline, and integrated Memory Protection Unit (MPU) supporting eight memory regions. Its system-level interconnect uses a multilayer AHB matrix and split APB buses to minimize arbitration delays between CPU and DMA operations.

Peripheral integration includes a dedicated General Purpose DMA controller (GPDMA), two enhanced I²C-bus interfaces (one Fast-mode Plus capable), five UARTs with RS-485 support, and a Quadrature Encoder Interface (QEI). The device lacks LCD controller and 32-bit EMC bus - confirmed by Table 2 ordering options - and omits FPU in this variant despite M4 core capability.

Key Specifications

Pinout & Package

LPC4076FBD144E is housed in a plastic low-profile quad flat package (LQFP144) with 144 leads, body size 20 × 20 × 1.4 mm (SOT486-1). All I/O pins are 5V tolerant with configurable pull-up/down resistors and support Cortex-M4 bit-banding. Pin functions are multiplexed via IOCON registers, with up to eight alternate functions per pin.

FAQ

Does LPC4076FBD144E include a hardware floating-point unit (FPU)?

No, the LPC4076FBD144E does not include an enabled hardware FPU. While the ARM Cortex-M4 core architecture supports FPU, Table 2 of the official datasheet explicitly lists "FPU" as "no" for all LPC4076 variants, including LPC4076FBD144E. Floating-point operations must be handled in software or via CMSIS-DSP library optimizations.

What is the maximum operating frequency of LPC4076FBD144E?

The LPC4076FBD144E operates at up to 120 MHz CPU frequency, achieved using the on-chip PLL driven by either the internal 12 MHz RC oscillator (±1%) or an external crystal (1–25 MHz). This frequency is sustained across the full industrial temperature range (−40 °C to +85 °C) under 3.3 V ±10% supply conditions.

How many CAN interfaces does LPC4076FBD144E support?

The LPC4076FBD144E integrates two independent CAN 2.0B controllers (CAN0 and CAN1), each with full message object buffers and acceptance filtering. Both interfaces are functional in the LQFP144 package, with CAN_TD1/CAN_RD1 on P0[1]/P0[0] and CAN_TD2/CAN_RD2 on P0[5]/P0[4], enabling dual-fieldbus redundancy or multi-network topology.

Is the LCD controller present in LPC4076FBD144E?

No, the LCD controller is absent in LPC4076FBD144E. Table 2 of the datasheet confirms "LCD" as "no" for all LPC4076 variants. This omission reduces pin count and power consumption, making LPC4076FBD144E suitable for non-display applications such as motor drives and protocol gateways where display resources are unnecessary.

What package type and pin count does LPC4076FBD144E use?

LPC4076FBD144E uses a plastic low-profile quad flat package (LQFP144) with 144 leads and body dimensions of 20 × 20 × 1.4 mm (SOT486-1). This package supports 165 GPIO pins, all 5V tolerant, and provides full access to dual CAN, USB, Ethernet (MII/RMII), SPIFI, and motor control PWM peripherals as specified in the datasheet.
