NXP Semiconductors LPC5536JHI48/00K

Overview

LPC5536JHI48/00K from NXP Semiconductors is a 32-bit ARM Cortex-M33 microcontroller with 256 KB flash, 128 KB SRAM, CAN FD interface, FlexSPI with 8 KB cache, and 32 GPIO pins in HVQFN48 package-designed for industrial motor control and sensor-fused edge nodes requiring secure, low-power real-time operation.

For engineers reviewing the LPC5536JHI48/00K datasheet, LPC5536JHI48/00K pinout, LPC5536JHI48/00K application, or LPC5536JHI48/00K equivalent, key selection criteria include its 150 MHz CPU frequency, dual FlexPWM subsystem supporting two 3-phase motors, 16-bit 2.0 Msamples/sec ADC with four simultaneous conversions, and hardware-accelerated PowerQuad DSP engine for fixed/floating-point math.

Technical Context

The LPC5536JHI48/00K implements an ARM Cortex-M33 core with TrustZone security, integrated FPU and MPU, and runs at up to 150 MHz using PLL0/PLL1 clock sources derived from internal FRO (12 MHz), external crystal (16–32 MHz), or RTC oscillator (32.768 kHz). Its memory subsystem includes 256 KB flash with 512-byte page erase, 128 KB SRAM split across Code Bus (16 KB) and System Bus (112 KB), and parity/ECC support differentiated per bank.

Peripherals are organized around two DMA controllers (DMA0: 52 channels; DMA1: 16 channels), eight Flexcomm interfaces configurable as USART/SPI/I2C/I2S, one dedicated CAN FD module with DMA, USB Full-Speed host/device (no PHY in this variant), and analog resources including four 16-bit ADCs, three 12-bit DACs, three OpAmps, and four comparators-all accessible via 32 GPIO pins in the HVQFN48 package.

FAQ

Does LPC5536JHI48/00K include an onboard USB PHY?

No, the LPC5536JHI48/00K does not integrate a USB PHY. While the USB Full-Speed host/device controller logic is present, external PHY hardware is required for physical layer connectivity. This differs from larger-package variants like LPC5536JBD100 which include the PHY. The HVQFN48 variant prioritizes pin count reduction and thermal efficiency over integrated USB analog circuitry.

What is the maximum ADC sample rate achievable with LPC5536JHI48/00K in 16-bit mode?

The LPC5536JHI48/00K supports a maximum ADC sample rate of 2.0 Msamples/sec in 16-bit mode. This performance is sustained across all four ADC instances simultaneously when using independent trigger sequences, enabling synchronized multi-channel acquisition for motor phase current and voltage sensing.

How many PWM outputs does LPC5536JHI48/00K support for motor control?

The LPC5536JHI48/00K supports 24 PWM outputs via its dual FlexPWM subsystem-each FlexPWM module contains four sub-modules delivering six outputs per module. This architecture enables full-bridge control of two independent 3-phase motors with programmable dead-time, fault protection, and center-aligned modulation.

Is the PowerQuad DSP accelerator accessible in non-secure mode on LPC5536JHI48/00K?

Yes, the PowerQuad DSP accelerator is fully accessible in non-secure mode on the LPC5536JHI48/00K. It operates independently of TrustZone state and provides hardware acceleration for FFT, FIR/IIR filtering, and matrix operations using its dedicated four 4 KB SRAM banks-enabling deterministic DSP workload execution without secure world intervention.

What boot sources are supported by LPC5536JHI48/00K, and how are they selected?

The LPC5536JHI48/00K supports boot from on-chip flash, external FlexSPI flash, or ISP handler-selected by the logic states of PIO0_5 and PIO0_7 at reset. Valid combinations include high/high (internal flash), high/low (FlexSPI XIP), and low/high (ISP handler). No external strapping resistors are needed; selection is purely pin-state driven at power-on.
