Product details
Overview
LPC55S04JBD64 from NXP Semiconductors is a 32-bit ARM Cortex-M33 microcontroller with TrustZone security, PRINCE flash encryption, CASPER crypto co-processor, and CAN FD interface. It integrates 128 KB on-chip flash, 80 KB SRAM, a 16-bit 2.0 Msamples/sec ADC, and operates up to 96 MHz for secure industrial control and IoT edge nodes.
For engineers reviewing the LPC55S04JBD64 datasheet, LPC55S04JBD64 pinout, LPC55S04JBD64 application, or LPC55S04JBD64 equivalent, key selection criteria include TrustZone-enabled secure boot, PRINCE-encrypted flash update capability, CAN FD real-time communication, and hardware-accelerated ECC via CASPER - all validated for operation from −40 °C to +105 °C in HTQFP64 package.
Technical Context
The LPC55S04JBD64 implements ARMv8-M architecture with TrustZone isolation, enabling secure execution environments for firmware and cryptographic keys. Its CASPER co-processor offloads Elliptic Curve Cryptography (ECC) operations, while PRINCE performs real-time AES-128 encryption/decryption of flash data during read/write cycles.
Security is reinforced by PUF-generated 64–4096-bit keys, SHA2-256 hash engine with DMA support, AES-256 encryption, and DICE-compliant Device Identifier Composition Engine. The device supports RSA-2048/4096 signature verification for secure boot and anti-rollback using x.509 certificate-based Root of Trust revocation.

FAQ
What is the maximum operating frequency of the LPC55S04JBD64?
The LPC55S04JBD64 operates at a maximum CPU frequency of 96 MHz, achieved via internal PLLs driven by the 12 MHz FRO or external crystal sources. This clock rate is fully supported across its −40 °C to +105 °C operating range and enables deterministic real-time performance for time-critical tasks such as CAN FD message scheduling and ADC sampling at 2.0 Msamples/sec.
Does the LPC55S04JBD64 support secure boot with public-key validation?
Yes, the LPC55S04JBD64 supports secure boot using RSASSA-PKCS1-v1_5 signatures of SHA256 digests, with validation against RSA-2048 or RSA-4096 public keys stored in x.509 certificates. Up to four root-of-trust keys can be revoked via PFR, and anti-rollback is enforced using image serial numbers - all implemented in ROM bootloader without software dependency.
How does PRINCE encryption work on the LPC55S04JBD64?
PRINCE on the LPC55S04JBD64 performs real-time AES-128 encryption during flash writes and decryption during reads, using keys derived from the PUF or software-supplied values. This occurs transparently at the flash controller level, requiring no CPU intervention, and protects application code and configuration data even if flash memory is physically extracted from the board.
Can the LPC55S04JBD64's ADC perform simultaneous sampling on multiple channels?
Yes, the LPC55S04JBD64's 16-bit ADC supports simultaneous conversions on two input channels belonging to the same differential pair - for example, ADC0_0 and ADC0_1 - enabling accurate phase-aligned measurements critical for motor control or power quality monitoring without inter-channel skew.
What debug interfaces are available on the LPC55S04JBD64?
The LPC55S04JBD64 provides Serial Wire Debug (SWD) with eight breakpoints and four watchpoints, plus Serial Wire Output (SWO) trace capability on PIO0_8. JTAG boundary scan is also supported via TRST/TCK/TMS/TDI/TDO pins (PIO0_2–PIO0_6), though SWD is the primary debug interface recommended for production programming and real-time tracing.
