LPC43S20FBD144

Microcontrollers Overview

The LPC43S20FBD144 is a dual-core microcontroller from NXP Semiconductors, integrating an Arm Cortex-M4 processor and an Arm Cortex-M0 co-processor. The Cortex-M4 core operates at frequencies up to 204 MHz and includes a hardware floating-point unit (FPU) for efficient signal processing. The device features up to 264 kB of SRAM, two high-speed USB interfaces with on-chip PHYs, and an Ethernet MAC controller. It supports advanced configurable peripherals including SCT, SGPIO, SPIFI, and multiple communication interfaces such as CAN, I2C, and UART.

Microcontrollers Procurement Notes

Verify the specific suffix 'E' or absence thereof against the manufacturer's current datasheet revision, as package marking and temperature ranges may vary. Confirm RoHS compliance status and lead-free specifications directly with NXP Semiconductors or authorized distributors prior to procurement. Ensure the LQFP144 package availability aligns with project timelines.

Microcontrollers Selection Notes

Select this component when both high computational throughput and low-power background management are required within a single chip. The dual-core design allows the M4 to handle complex algorithms while the M0 manages peripheral interrupts and power modes. Consider the available SRAM size and peripheral count relative to application complexity compared to single-core alternatives in the LPC43 family.

Microcontrollers Part Context

This part belongs to the NXP LPC43Sxx series, which extends the standard LPC4300 family by adding integrated Ethernet capabilities. It shares the same core architecture and peripheral set as the LPC4320 but includes the Ethernet MAC controller. The series targets applications needing robust networking alongside real-time control capabilities.

Microcontrollers Replacement Considerations

LPC4320FBD144: Similar dual-core MCU but lacks the integrated Ethernet MAC controller. LPC4350FBD144: Offers higher performance cores and additional memory resources. LPC4370FBD144: Features a faster Cortex-M4 core and higher-resolution ADCs.
