Product details
Overview
LPC55S04JHI48J from NXP Semiconductors is a secure ARM Cortex-M33 microcontroller with TrustZone, 128 KB flash, 80 KB SRAM, PRINCE real-time flash encryption, CASPER crypto co-processor, and CAN FD interface-designed for industrial edge nodes requiring secure firmware updates and sensor fusion in harsh environments.
For engineers reviewing the LPC55S04JHI48J datasheet, LPC55S04JHI48J pinout, LPC55S04JHI48J application, or LPC55S04JHI48J equivalent, this page delivers verified specifications, HVQFN48 package mapping, security feature implementation details, and validated alternative MCUs for secure embedded control designs.
Technical Context
The LPC55S04JHI48J implements ARMv8-M architecture with TrustZone isolation, enabling hardware-enforced separation of secure and non-secure firmware execution domains. Its CASPER co-processor accelerates ECC operations (NIST P-256/P-384), while PRINCE performs AES-128 on-the-fly encryption/decryption of flash reads and writes.
It integrates dual DMA controllers (23+10 channels), a programmable SCTimer/PWM with 16 match/capture registers, and a 16-bit 2.0 Msamples/sec ADC supporting simultaneous differential conversions-enabling deterministic real-time control with cryptographic integrity verification.

Equivalent & Alternatives
The following parts are listed as comparable options for similar secure microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LPC55S16JBD64 | HTQFP64 package, 256 KB flash, 96 KB SRAM, 45 GPIO, 9 ADC channels | Higher peripheral count and memory for complex HMI or multi-interface gateways | Select when needing >30 GPIO or full 9-channel ADC; not pin-compatible with HVQFN48 |
| RA6M5GFPMXXB | Renesas RA6M5 core (Cortex-M33), 1 MB flash, 448 KB SRAM, no PRINCE/CASPER, includes Ethernet MAC | Targeted at networked industrial controllers requiring TCP/IP stack offload | Choose for Ethernet connectivity priority; lacks on-the-fly flash encryption and ECC acceleration of LPC55S04JHI48J |
Compared with LPC55S04JHI48J, LPC55S16JBD64 offers greater memory and I/O but requires PCB redesign due to HTQFP64 footprint, while RA6M5GFPMXXB provides Ethernet and larger memory but omits PRINCE and CASPER-making LPC55S04JHI48J optimal for compact, crypto-intensive edge nodes where flash protection and ECC speed are critical.

FAQ
What is the maximum operating frequency of the LPC55S04JHI48J CPU core?
The LPC55S04JHI48J features an ARM Cortex-M33 core rated for operation up to 96 MHz. This frequency is sustained using the internal 96 MHz Free Running Oscillator (FRO), which is trimmed to ±1% accuracy across voltage and 0°C to 85°C, or ±2% over −40°C to 105°C. PLLs can also derive this clock from lower-frequency sources including the 32.768 kHz RTC oscillator.
Does the LPC55S04JHI48J support secure boot with public-key validation?
Yes, the LPC55S04JHI48J supports secure boot using RSASSA-PKCS1-v1_5 signatures over SHA256 digests, with RSA-2048 and RSA-4096 public keys. Root-of-trust keys are stored as SHA-256 hashes in protected flash (PFR), and up to four revocable keys and 16 image key revocations are supported via x509 certificate serial numbers-fully compliant with DICE v2.0 Level 00.
How many ADC channels does the LPC55S04JHI48J provide, and what is its sampling rate?
The LPC55S04JHI48J integrates a 16-bit ADC supporting up to 7 input channels (5 differential pairs) with a maximum sampling rate of 2.0 Msamples/sec. It supports simultaneous conversions on paired differential inputs, and includes an integrated temperature sensor and five-input analog comparator with selectable internal/external references.
What security accelerators are integrated into the LPC55S04JHI48J?
The LPC55S04JHI48J includes three dedicated hardware security blocks: PRINCE for real-time AES-128 flash encryption/decryption, CASPER for ECC scalar multiplication (P-256/P-384), and a PUF engine generating and reconstructing keys from 64 to 4096 bits using SRAM fingerprinting-enabling secure key storage without battery-backed memory.
Is the LPC55S04JHI48J pin-compatible with other members of the LPC55S0x family?
No-LPC55S04JHI48J uses the HVQFN48 package (7 × 7 mm), while LPC55S04JBD64 and LPC55S16 variants use HTQFP64 (10 × 10 mm). Pin functions differ between packages; for example, HVQFN48 supports 30 GPIO and 7 Flexcomm interfaces, whereas HTQFP64 supports 45 GPIO and 8 Flexcomm interfaces. Migration requires PCB redesign.
