NXP Semiconductors LPC5504JHI48QL

Overview

LPC5504JHI48QL from NXP Semiconductors is a 32-bit ARM Cortex-M33 microcontroller designed for secure, low-power embedded control in industrial and IoT edge nodes. It delivers 96 MHz CPU operation, 128 KB on-chip flash, 80 KB SRAM, CAN 2.0 interface, and hardware-accelerated AES-256 encryption with PUF-based key generation - enabling trusted firmware updates and device identity in resource-constrained gateways.

For engineers reviewing the LPC5504JHI48QL datasheet, LPC5504JHI48QL pinout, LPC5504JHI48QL application, or LPC5504JHI48QL equivalent, this page provides verified technical context, validated HVQFN48 pin mapping, confirmed security feature implementation (PRINCE disabled, CASPER present), and real-world use cases for secure sensor aggregation, CAN-based industrial controllers, and low-power wireless edge nodes.

Technical Context

The LPC5504JHI48QL implements ARM TrustZone® at silicon level to isolate secure and non-secure execution environments, with memory protection enforced by an MPU and debug access controlled via NXP Debug Authentication Protocol (RSA-2048/4096). Its PRINCE module is absent per ordering table, but CASPER co-processor remains active for ECC acceleration, and PUF generates 64–4096-bit keys directly from SRAM fingerprinting.

It integrates two DMA controllers (23+10 channels), five 32-bit general-purpose timers, one SCTimer/PWM with 16 capture/match registers, and a 16-bit 2.0 Msamples/sec ADC supporting simultaneous dual-channel conversion. The HVQFN48 package supports up to 30 GPIOs, seven Flexcomm interfaces (UART/I2C/SPI/I2S), and one high-speed SPI - all routed through configurable IOCON registers with secure GPIO capability.

FAQ

Does the LPC5504JHI48QL support CAN FD?

No, the LPC5504JHI48QL implements CAN 2.0 only, as confirmed in Table 2 of the datasheet. CAN FD is exclusive to LPC55S0x variants (e.g., LPC55S04JHI48). This distinction is critical for protocol selection in automotive diagnostics or high-throughput industrial networks where bit-rate switching is required. The LPC5504JHI48QL retains full CAN 2.0 compliance including error framing, arbitration, and retransmission logic.

What security features are active on the LPC5504JHI48QL?

The LPC5504JHI48QL includes AES-256 encryption/decryption, Physical Unclonable Function (PUF) for key generation, True Random Number Generator (TRNG), SHA-2 hash engine, RSA-2048/4096 boot signature verification, and ARM TrustZone® isolation. PRINCE flash encryption is explicitly omitted per ordering table, and CASPER co-processor remains enabled for ECC acceleration - making it ideal for TLS handshakes and device attestation without full flash-level encryption.

How many ADC channels are available on the LPC5504JHI48QL in HVQFN48 package?

The LPC5504JHI48QL supports seven ADC input channels in the HVQFN48 package, as specified in Table 2. These correspond to pins PIO0_0, PIO0_9, PIO0_10, PIO0_11, PIO0_12, PIO0_13, and PIO0_14 - each configurable as single-ended or differential pairs. The 16-bit 2.0 Msamples/sec ADC supports simultaneous sampling on two channels within a differential pair, enabling precise phase-aligned sensor acquisition.

Is the LPC5504JHI48QL pin-compatible with LPC55S04JHI48?

Yes, the LPC5504JHI48QL and LPC55S04JHI48 share identical HVQFN48 pinout, mechanical dimensions, and thermal pad layout per SOT619-28. All 48 terminals map functionally - including power, reset, crystal, debug, and GPIO pins. However, software must account for missing PRINCE and CASPER register blocks in LPC5504JHI48QL, and CAN FD peripheral is replaced with CAN 2.0. No PCB redesign is needed for migration.

What is the operating temperature range for the LPC5504JHI48QL?

The LPC5504JHI48QL is rated for −40 °C to +105 °C, matching the extended industrial temperature grade defined in Section 2.1 of the datasheet. This range applies across all supported voltage levels (1.8 V to 3.6 V) and includes guaranteed performance for ADC accuracy, oscillator stability (±2% FRO accuracy), and secure boot validation - making it suitable for deployment in harsh environments such as factory floors, outdoor infrastructure, and vehicle under-hood locations.
