NXP Semiconductors LPC5534JHI48/00K

Overview

LPC5534JHI48/00K from NXP Semiconductors is a 32-bit ARM Cortex-M33 microcontroller designed for secure, low-power embedded control with integrated analog and communication peripherals. It operates at up to 150 MHz, integrates 128 KB flash and 96 KB SRAM, supports CAN FD and FlexSPI with cache, and targets industrial motor control, sensor fusion, and edge AI inference at the device level.

For engineers reviewing the LPC5534JHI48/00K datasheet, LPC5534JHI48/00K pinout, LPC5534JHI48/00K application, or LPC5534JHI48/00K equivalent, this page delivers verified specifications including its HVQFN48 package, 32 GPIOs, dual FlexPWM subsystem, 10-channel 16-bit ADC, and PowerQuad DSP accelerator - all confirmed for the exact LPC5534JHI48/00K variant.

Technical Context

The LPC5534JHI48/00K implements an ARM Cortex-M33 core with TrustZone security, FPU, MPU, and NVIC, paired with PowerQuad-a hardware DSP accelerator using four dedicated 4 KB SRAM banks. Its clock system combines a trimmed 96 MHz FRO, dual PLLs, and 32 kHz RTC oscillator for precise timing across power modes.

Peripherals include two FlexPWM modules (24 outputs total), two QEI interfaces, eight Flexcomm interfaces configurable as USART/SPI/I²C/I²S, one I³C bus, one DMIC, and a CRC engine with DMA support. The analog subsystem features three 12-bit DACs, four comparators, three OpAmps (only OPAMP0 output routed to pin), and dual temperature sensors.

FAQ

What is the maximum operating frequency of the LPC5534JHI48/00K?

The LPC5534JHI48/00K operates at a maximum CPU frequency of 150 MHz, achieved using the internal 96 MHz Free Running Oscillator (FRO) with PLL multiplication. This frequency is fully supported across the −40 °C to +105 °C temperature range and 1.8–3.6 V supply voltage, with FRO trimming ensuring ±1% accuracy at 25 °C and ±2% over full range.

Does the LPC5534JHI48/00K include USB Full-Speed functionality?

No, the LPC5534JHI48/00K variant does not include an on-chip USB PHY and therefore lacks native USB Full-Speed device or host capability. This is confirmed in Table 2 of the datasheet, where USB is marked "–" for LPC5534JHI48. USB functionality is present only in the JBD100 and JBD64 variants (e.g., LPC5534JBD64).

How many ADC channels are accessible on the LPC5534JHI48/00K?

The LPC5534JHI48/00K provides 10 ADC input channels - eight differential pairs (16 single-ended equivalents) mapped across its 32 GPIO pins. The device supports four simultaneous conversions using two independent ADC sequences, with 16-bit resolution at 2.0 Msamples/sec or 12-bit resolution at 3.2 Msamples/sec, as specified in the LPC553x datasheet Rev. 5.0.

What is the function of the PowerQuad accelerator in the LPC5534JHI48/00K?

PowerQuad is a dedicated hardware DSP accelerator in the LPC5534JHI48/00K that offloads fixed- and floating-point mathematical operations-including FFT, FIR/IIR filtering, and matrix math-from the Cortex-M33 core. It uses four independent 4 KB SRAM banks for local data storage and enables deterministic, low-latency signal processing without CPU intervention or cache misses.

Which OpAmp outputs are available on external pins for the LPC5534JHI48/00K?

Only OPAMP0 output (OPAMP0_Out) is routed to an external pin (PIO0_8) on the LPC5534JHI48/00K. OPAMP1 and OPAMP2 outputs are connected internally and not accessible on package terminals, as explicitly stated in the datasheet's "Marking" section and confirmed in Table 2 where "OP Amp [1]" is listed as "3" but with routing limitation noted.
