FAQ

What is the maximum operating frequency of the LPC5536JBD100K?

The LPC5536JBD100K features an ARM Cortex-M33 core rated for operation up to 150 MHz. This maximum frequency is achievable using internal PLLs driven by the 12 MHz FRO or external oscillators, with voltage and temperature conditions meeting the −40 °C to +105 °C specification. The LPC5536JBD100K maintains timing compliance across its full industrial temperature range when supplied within the 1.8 V to 3.6 V VDDIO and VDDCORE specifications.

Does the LPC5536JBD100K support crystal-less USB Full-Speed device operation?

Yes, the LPC5536JBD100K supports crystal-less USB Full-Speed device mode using its internal 96 MHz FRO trimmed to ±1% accuracy, combined with software calibration per AN13527. This eliminates the need for an external 12 MHz crystal in USB device applications, reducing BOM cost and PCB area. The LPC5536JBD100K retains full USB FS host capability with external crystal or clock source.

How many ADC channels and what resolution does the LPC5536JBD100K support?

The LPC5536JBD100K integrates four 16-bit analog-to-digital converters capable of 2.0 Msamples/sec in 16-bit mode (or 3.2 Msamples/sec in 12-bit mode), supporting up to four simultaneous conversions. It provides 23 ADC input channels - including eight differential pairs - with internal temperature sensor routing to both ADC instances. The LPC5536JBD100K's ADC subsystem supports programmable triggers, DMA transfers, and hardware averaging for noise reduction.

What is the purpose of the PowerQuad coprocessor in the LPC5536JBD100K?

The PowerQuad coprocessor in the LPC5536JBD100K accelerates fixed- and floating-point DSP operations - including FFT, FIR/IIR filtering, matrix math, and trigonometric functions - using dedicated hardware and four 4 KB SRAM banks. It operates independently of the Cortex-M33 core, enabling real-time signal processing without CPU load. The LPC5536JBD100K leverages PowerQuad for sensor fusion, motor control algorithms, and audio preprocessing while maintaining deterministic latency.

Which package type is used for the LPC5536JBD100K and how many pins does it have?

The LPC5536JBD100K uses the HLQFP100 package: a plastic low-profile quad flat package with 100 leads, 0.5 mm pitch, and 14 mm × 14 mm body size (SOT1570-5). This package provides 66 GPIOs, full peripheral pinout accessibility, and thermal performance suited for industrial environments. The LPC5536JBD100K's HLQFP100 footprint is compatible with standard reflow profiles and supports automated optical inspection (AOI) during manufacturing.
