NXP Semiconductors LPC4313JBD144E

Overview

LPC4313JBD144E from NXP Semiconductors is a dual-core ARM Cortex-M4F/M0 microcontroller in LQFP144 package, operating up to 204 MHz with 512 kB flash (256 kB per bank), 104 kB SRAM, and no Ethernet or LCD controller. It integrates dual 10-bit ADCs (8 channels total), one 10-bit DAC, motor control PWM, QEI, and USB0 host/device interface - deployed in industrial motor control and power management systems.

For engineers reviewing the LPC4313JBD144E datasheet, LPC4313JBD144E pinout, LPC4313JBD144E application, or LPC4313JBD144E equivalent, key selection criteria include dual-core real-time partitioning, 144-pin LQFP footprint compatibility, absence of Ethernet/LCD peripherals, and verified USB0 + motor control PWM support for embedded motion control designs.

Technical Context

The LPC4313JBD144E implements a tightly coupled dual-core architecture: the Cortex-M4F core handles high-performance signal processing and real-time tasks with hardware FPU and MPU, while the Cortex-M0 co-processor offloads peripheral management and deterministic I/O control at up to 204 MHz. Both cores share memory via AHB multilayer matrix and synchronize through event router and shared SRAM.

Its peripheral set is trimmed for cost-sensitive industrial control: includes SPIFI for XIP flash execution, EMC for external SDRAM/SRAM, SCTimer/PWM for flexible waveform generation, GIMA for cross-triggered event routing, and C_CAN 2.0B for fieldbus communication - all without Ethernet MAC, LCD controller, or USB1 PHY.

FAQ

What is the maximum operating frequency of the LPC4313JBD144E?

The LPC4313JBD144E operates at a maximum CPU frequency of 204 MHz on both its ARM Cortex-M4F and Cortex-M0 cores. This performance level is achieved using internal PLLs fed from either the 1–25 MHz crystal oscillator or the 12 MHz internal RC oscillator, with voltage and temperature compensation ensuring stability across the full -40 °C to +105 °C range specified for the LPC4313JBD144E.

Does the LPC4313JBD144E include an Ethernet MAC?

No, the LPC4313JBD144E does not include an Ethernet MAC. As confirmed in Table 2 of the official NXP datasheet (Rev. 5.4), Ethernet is explicitly marked "no" for the LPC4313JBD144E variant. This distinguishes it from higher-tier LPC43xx parts like the LPC4337 or LPC4357, and makes the LPC4313JBD144E suitable for cost-optimized, non-networked industrial control applications.

How much SRAM and flash memory does the LPC4313JBD144E have?

The LPC4313JBD144E integrates 104 kB of on-chip SRAM and 512 kB of flash memory, split into two 256 kB banks for independent erase/program operations. This memory configuration supports robust firmware updates and real-time data buffering - essential for applications such as motor control and power metering where the LPC4313JBD144E is commonly deployed.

Is the LPC4313JBD144E pin-compatible with other LPC43xx LQFP144 variants?

Yes, the LPC4313JBD144E shares the same LQFP144 mechanical footprint and pin assignment with other LPC43xx devices in the JBD144 package (e.g., LPC4333JBD144, LPC4323JBD144). However, functional pin mapping differs where peripherals are omitted - for example, ENET-related pins on the LPC4313JBD144E are reserved or repurposed, requiring schematic review before substitution.

What USB capabilities does the LPC4313JBD144E support?

The LPC4313JBD144E supports one High-speed USB 2.0 interface (USB0) with integrated on-chip high-speed PHY, enabling host, device, and OTG operation. It does not include USB1 - which requires an external ULPI PHY - nor does it support USB audio class natively. The USB0 interface is fully supported by ROM-based stack software, simplifying HID and CDC implementation in the LPC4313JBD144E.
