NXP Semiconductors LPC55S16JEV98E

Overview

LPC55S16JEV98E from NXP Semiconductors is a 32-bit Arm Cortex-M33 microcontroller with TrustZone security, PRINCE flash encryption, CASPER crypto co-processor, 256 KB on-chip flash, 96 KB SRAM, CAN FD, USB full-speed and high-speed interfaces, and a 16-bit 2.0 Msamples/sec ADC. It targets secure industrial control, automotive body electronics, and IoT edge nodes requiring cryptographic integrity and real-time responsiveness.

For engineers reviewing the LPC55S16JEV98E datasheet, LPC55S16JEV98E pinout, LPC55S16JEV98E application, or LPC55S16JEV98E equivalent, key selection criteria include TrustZone-enforced memory isolation, PRINCE-encrypted firmware updates, CASPER-accelerated ECC operations, 64 GPIOs in VFBGA98 package, and dual USB (FS/HS) support with crystal-less FS operation.

Technical Context

The LPC55S16JEV98E implements Arm TrustZone to partition secure and non-secure execution environments, with hardware-enforced memory isolation and secure boot using RSA-2048/4096 signatures. Its CASPER co-processor offloads elliptic curve cryptography (ECC), while PRINCE enables real-time AES-256 encryption/decryption of flash reads and writes.

It integrates two DMA controllers (23+10 channels), nine Flexcomm peripherals configurable as USART/SPI/I2C/I2S, SCTimer/PWM with 16 capture/match registers, and a 24-bit Multi-Rate Timer for deterministic interrupt scheduling - all operating under a 150 MHz Cortex-M33 core with FPU and MPU.

FAQ

What security features does the LPC55S16JEV98E provide beyond standard TrustZone?

The LPC55S16JEV98E extends Arm TrustZone with PRINCE real-time flash encryption/decryption, CASPER hardware-accelerated ECC, PUF-based key generation (64–4096 bits), DICE-compliant secure boot, and SHA2/AES-256 engines. These features enable end-to-end firmware protection, secure key derivation, and cryptographically verified OTA updates - capabilities not inherent to TrustZone alone. The LPC55S16JEV98E implements them as integrated silicon blocks with dedicated DMA paths for minimal CPU overhead.

Does the LPC55S16JEV98E support crystal-less USB full-speed operation?

Yes, the LPC55S16JEV98E supports crystal-less USB full-speed device operation using its internal 48 MHz clock derived from the FRO, eliminating the need for an external 48 MHz crystal or oscillator. This feature reduces BOM cost and PCB area while maintaining USB compliance. The LPC55S16JEV98E achieves this via software library support documented in Technical Note TN00065, and it applies only to USB device mode - USB host mode still requires an external clock source.

How many GPIOs are available on the LPC55S16JEV98E in the VFBGA98 package?

The LPC55S16JEV98E provides 64 GPIOs in the VFBGA98 package, as confirmed in Table 2 of the datasheet. These pins support multiple functions including ADC inputs, comparator channels, Flexcomm interfaces, and secure GPIO capability. All GPIO registers reside on the AHB bus for low-latency access, and the DMA controllers support direct GPIO port transfers - enabling high-throughput peripheral synchronization without CPU intervention in the LPC55S16JEV98E design.

What is the maximum ADC sampling rate and resolution supported by the LPC55S16JEV98E?

The LPC55S16JEV98E integrates a 16-bit successive approximation ADC capable of up to 2.0 million samples per second (2.0 Msamples/sec). It supports simultaneous conversions on two channels within a differential pair, with five differential input pairs (10 single-ended channels) and internal/external trigger sources. This performance enables high-fidelity signal acquisition in motor control, power quality monitoring, and medical sensing applications - all while maintaining the LPC55S16JEV98E's security and real-time determinism.

Can the LPC55S16JEV98E execute secure boot from PRINCE-encrypted flash regions?

Yes, the LPC55S16JEV98E ROM bootloader explicitly supports booting images from PRINCE-encrypted flash regions, as stated in Section 2 "Features and benefits" of the datasheet. The secure boot process verifies the image signature (RSA-2048/4096) before decryption and execution, ensuring that only authenticated and encrypted firmware runs. This capability is intrinsic to the LPC55S16JEV98E's architecture and requires no external components or software modifications to enable.
