Product details
Overview
LPC5504JHI48EL from NXP Semiconductors is a 32-bit ARM Cortex-M33 microcontroller designed for secure, low-power embedded control in industrial and automotive applications. It operates at up to 96 MHz, integrates 128 KB flash and 80 KB SRAM, includes CAN 2.0 (not CAN FD), PRINCE flash encryption, and a 16-bit 2.0 Msamples/sec ADC with 7 input channels - deployed in battery-powered sensor nodes requiring tamper-resistant firmware updates.
For engineers reviewing the LPC5504JHI48EL datasheet, LPC5504JHI48EL pinout, LPC5504JHI48EL application, or LPC5504JHI48EL equivalent, key selection criteria include its HVQFN48 package footprint, TrustZone®-enabled security architecture, PRINCE-based encrypted flash, CAN 2.0 interface (not CAN FD), and support for secure boot with RSA-2048/4096 verification.
Technical Context
The LPC5504JHI48EL implements ARM TrustZone® for hardware-enforced memory isolation between secure and non-secure execution states, enabling secure firmware update and cryptographic key protection. Its PRINCE module performs real-time AES-128 encryption/decryption of on-chip flash reads and writes without CPU intervention.
It features two DMA controllers (23-channel DMA0 and 10-channel DMA1), a programmable logic unit (PLU) for glue logic offload, and a dual-domain power management unit supporting deep power-down with RAM retention. The device lacks CASPER crypto co-processor and PUF - differentiating it from LPC55S0x variants.

FAQ
Does LPC5504JHI48EL support CAN FD?
No, LPC5504JHI48EL implements CAN 2.0 only. Unlike LPC55S0x variants, it lacks the CAN FD controller and associated DMA support. This is confirmed in Table 2 of the datasheet, which lists "CAN2.0" under the CAN FD column for all LPC550x parts including LPC5504JHI48EL. Designers requiring CAN FD must select an LPC55S0x variant such as LPC55S04JHI48.
What is the maximum ADC sampling rate supported by LPC5504JHI48EL?
LPC5504JHI48EL supports a maximum ADC sampling rate of 2.0 Msamples/sec. This applies to its 16-bit successive approximation register (SAR) ADC, which provides 7 single-ended input channels. Simultaneous sampling is supported on differential channel pairs, and conversions can be triggered by internal timers or external signals as specified in the analog peripherals section of the datasheet.
Is the PRINCE encryption module present in LPC5504JHI48EL?
Yes, LPC5504JHI48EL includes the PRINCE module for real-time AES-128 encryption and decryption of on-chip flash memory. This enables secure firmware updates and asset protection without CPU overhead. PRINCE is explicitly listed in Table 2 for all LPC550x parts, and its operation - encrypting data during write and decrypting during read - is detailed in the security features section of the datasheet.
Does LPC5504JHI48EL include a Physical Unclonable Function (PUF)?
No, LPC5504JHI48EL does not include a PUF controller. Table 2 confirms PUF is marked "-" for all LPC550x parts, distinguishing them from LPC55S0x variants which list "yes". Similarly, CASPER crypto co-processor, HASH-AES engine, and DICE-compliant secure boot are absent - making LPC5504JHI48EL a cost-optimized variant focused on foundational TrustZone® and PRINCE security.
What debug interfaces are available on LPC5504JHI48EL?
LPC5504JHI48EL supports Serial Wire Debug (SWD) via PIO0_2 (TRST), PIO0_3 (TCK), PIO0_4 (TMS), PIO0_5 (TDI), and PIO0_6 (TDO) - accessible through the HVQFN48 package's JTAG boundary scan pins. It also provides Serial Wire Output (SWO) on PIO0_8 for real-time trace. JTAG is disabled during normal operation and only active in boundary scan mode; SWD remains available for full debug and programming throughout the development cycle.
