NXP Semiconductors LPC55S16JEV98Y

Overview

LPC55S16JEV98Y from NXP Semiconductors is an Arm Cortex-M33 microcontroller with TrustZone security, 256 KB flash, 96 KB SRAM, PRINCE real-time flash encryption, CASPER crypto co-processor, and dual USB (FS + HS) supporting crystal-less full-speed operation - deployed in secure industrial gateways requiring authenticated firmware updates and CAN FD communication.

For engineers reviewing the LPC55S16JEV98Y datasheet, LPC55S16JEV98Y pinout, LPC55S16JEV98Y application, or LPC55S16JEV98Y equivalent, key selection criteria include TrustZone-enforced memory isolation, PUF-based key generation, 2.0 Msamples/sec 16-bit ADC with simultaneous differential conversion, and VFBGA98 package compatibility with high-density PCB layouts.

Technical Context

The LPC55S16JEV98Y implements Arm TrustZone to enforce hardware-isolated secure and non-secure execution environments, with secure boot verified via RSA-2048/4096 signatures and SHA256 digest. Its CASPER co-processor accelerates ECC operations, while PRINCE enables on-the-fly AES-256 encryption/decryption of flash contents during read/write.

It integrates nine Flexcomm interfaces (0–8), each configurable as USART, SPI, I²C, or I²S, with dedicated DMA controllers for USB HS/FS, CAN FD, and SCTimer/PWM. The 16-bit ADC supports five differential pairs (10 SE channels) at up to 2.0 Msamples/sec with simultaneous sampling capability.

FAQ

What is the maximum operating frequency of the LPC55S16JEV98Y CPU core?

The LPC55S16JEV98Y features an Arm Cortex-M33 core rated for operation up to 150 MHz. This frequency is achievable using internal PLLs driven by the 12 MHz FRO or external crystal sources. The core includes a floating-point unit and memory protection unit, enabling deterministic real-time performance in safety-critical applications. All timing specifications in the official NXP datasheet Rev. 1.8 are validated across the −40 °C to +105 °C temperature range.

Does the LPC55S16JEV98Y support secure boot with public-key cryptography?

Yes, the LPC55S16JEV98Y supports secure boot using RSASSA-PKCS1-v1_5 signatures of SHA256 digests, with RSA-2048 and RSA-4096 public key support. Root of Trust keys are stored as SHA-256 hashes in protected flash, and image revocation uses x509 certificate serial numbers. This implementation complies with NXP's Secure Boot specification v2.0 and Trusted Computing Group DICE v2.0 requirements.

What analog capabilities does the LPC55S16JEV98Y provide for sensor interfacing?

The LPC55S16JEV98Y integrates a 16-bit ADC with up to 2.0 Msamples/sec sampling rate, supporting five differential channel pairs (10 single-ended inputs) and simultaneous conversions on paired channels. It also includes an integrated temperature sensor, five-input analog comparator with selectable reference, and programmable gain amplifier functionality via IOCON register configuration - all accessible without external components.

How does the PRINCE module function in the LPC55S16JEV98Y?

The PRINCE module in the LPC55S16JEV98Y performs real-time AES-256 encryption of data written to on-chip flash and decryption of encrypted data during read operations. It operates transparently in the flash controller path, requiring no software intervention. Keys are derived from the PUF or supplied via secure boot flow, and region-based encryption enables selective protection of application code, configuration tables, and firmware update images within the 256 KB flash.

Is the LPC55S16JEV98Y pin-compatible with other members of the LPC55S1x family?

Yes, the LPC55S16JEV98Y shares identical pinout and electrical characteristics with other VFBGA98 variants in the LPC55S1x family, including LPC55S14JEV98 and LPC55S06JEV98. All use the SOT1982-1 package variant, with matching ball map, I/O voltage tolerances, and reset behavior. Firmware and PCB layout are interchangeable across these parts when configured for equivalent peripheral usage and memory requirements.
