NXP Semiconductors LPC55S26JEV98E

Overview

LPC55S26JEV98E from NXP Semiconductors is a 32-bit Arm Cortex-M33 microcontroller with hardware-accelerated cryptography (CASPER), 256 KB on-chip flash, 144 KB SRAM, PRINCE real-time flash encryption, and dual-mode USB 2.0 (full-speed + high-speed) for secure embedded control in industrial gateways and IoT edge nodes.

For engineers reviewing the LPC55S26JEV98E datasheet, LPC55S26JEV98E pinout, LPC55S26JEV98E application, or LPC55S26JEV98E equivalent, key selection criteria include its VFBGA98 package, 150 MHz CPU frequency, secure boot with RSA-2048/4096, PUF-based key generation, and 64 GPIOs with programmable logic unit (PLU) support.

Technical Context

The LPC55S26JEV98E implements Arm TrustZone for secure execution environments, with CASPER co-processor offloading ECC and FFT operations while the main M33 core runs at up to 150 MHz. Its PRINCE module enables transparent AES-128 encryption/decryption of flash reads and writes without software overhead.

Security is enforced via integrated PUF (64–4096-bit key generation), TRNG, SHA2-AES engine, and debug authentication using RSA-2048/4096. The device supports secure boot with x.509 certificate validation, anti-rollback via image key revocation, and sealed-part fault analysis mode.

FAQ

What is the maximum operating frequency of the LPC55S26JEV98E?

The LPC55S26JEV98E operates at a maximum CPU frequency of 150 MHz. This is achieved using PLL0 or PLL1 driven by internal FRO (12 MHz or 1 MHz), external crystal (16–32 MHz), or 32.768 kHz RTC oscillator. The FRO is factory-trimmed to ±1% accuracy across 0°C to 85°C for date codes 2041 and later, ensuring stable clocking without external components.

Does the LPC55S26JEV98E support secure boot with public-key cryptography?

Yes, the LPC55S26JEV98E supports secure boot using RSASSA-PKCS1-v1_5 signatures of SHA256 digests. It validates images with RSA-2048 or RSA-4096 public keys stored in x.509 certificates, supports up to four revocable Root of Trust keys, and enforces anti-rollback via image key certificate serial number revocation - all implemented in ROM bootloader.

What package type and pin count does the LPC55S26JEV98E use?

The LPC55S26JEV98E uses a VFBGA98 package: a 7 mm × 7 mm thin fine-pitch ball grid array with 98 solder balls arranged in a 10×10 grid (corner balls omitted), 0.5 mm pitch, and lead-free RoHS-compliant construction per SOT1982-1 specification.

How does the PRINCE module function in the LPC55S26JEV98E?

The PRINCE module in the LPC55S26JEV98E performs real-time AES-128 encryption of data written to on-chip flash and decryption of data read from encrypted regions - all transparently handled in hardware without CPU intervention. Keys are derived from the PUF or supplied via software, enabling secure asset protection and authenticated firmware updates.

Can the LPC55S26JEV98E operate without an external crystal?

Yes, the LPC55S26JEV98E can operate without external crystals. Its internal Free Running Oscillator (FRO) provides 96 MHz and 12 MHz outputs (±1% accuracy from 0°C to 85°C for date code 2041+), and USB full-speed device mode supports crystal-less operation using a software library (TN00063). The 32.768 kHz RTC oscillator also has an internal FRO option.
