NXP Semiconductors LPC5526JEV98Y

Overview

LPC5526JEV98Y from NXP Semiconductors is a 32-bit Arm Cortex-M33 microcontroller designed for secure embedded applications, operating at up to 150 MHz with 256 KB on-chip flash, 144 KB SRAM, and full-speed + high-speed USB interfaces. It integrates a 16-bit 1.0 Msamples/sec ADC, SCTimer/PWM, PRINCE flash encryption, and supports secure boot using RSA-2048/4096 signatures - deployed in industrial IoT gateways requiring tamper-resistant firmware updates.

For engineers reviewing the LPC5526JEV98Y datasheet, LPC5526JEV98Y pinout, LPC5526JEV98Y application, or LPC5526JEV98Y equivalent, key selection considerations include VFBGA98 package compatibility, absence of CASPER crypto co-processor, PRINCE/PUF/SHA-AES security module availability, and GPIO count (64 pins) versus LPC55S26JEV98Y.

Technical Context

The LPC5526JEV98Y implements an Arm Cortex-M33 core with Memory Protection Unit (MPU), FPU, and DSP extensions but excludes the CASPER cryptographic co-processor found in LPC55S2x variants. Its security architecture relies on PRINCE for real-time flash encryption/decryption, SHA2/AES hardware acceleration, and PUF-based key generation - all enabled via dedicated DMA controllers and protected memory regions.

It features nine Flexcomm interfaces (FC0–FC8), each configurable as USART/SPI/I2C/I2S, plus dual USB 2.0 controllers (FS+HS), SDIO interface supporting SDR25 (52 MHz), and a 24-bit Multi-Rate Timer (MRT) for deterministic interrupt scheduling - all clocked from internal FROs (96/12/1 MHz) or external crystals (16–32 MHz and 32.768 kHz).

Key Specifications

Pinout & Package

VFBGA98 package: thin fine-pitch ball grid array with 98 solder balls in 7 mm × 7 mm body and 0.5 mm pitch (SOT1982-1). Pin functions are software-configurable via IOCON registers; default reset state disables most pull-ups/pull-downs except on debug and boot-determining pins (e.g., PIO0_5).

FAQ

What is the maximum operating frequency of the LPC5526JEV98Y?

The LPC5526JEV98Y operates at a maximum CPU frequency of 150 MHz, achieved using internal PLLs driven by the 96 MHz Free Running Oscillator (FRO) or external crystal sources. This frequency is sustained across the full industrial temperature range (-40 °C to +105 °C) and 1.8–3.6 V supply, enabling deterministic real-time execution in demanding control applications. The LPC5526JEV98Y maintains this rating without requiring external high-frequency clocks.

Does the LPC5526JEV98Y include the CASPER cryptographic co-processor?

No, the LPC5526JEV98Y does not include the CASPER crypto co-processor. This feature is exclusive to the LPC55S2x series (e.g., LPC55S26JEV98Y). The LPC5526JEV98Y retains full PRINCE flash encryption, SHA2-AES hardware acceleration, PUF key generation, and secure boot - making it suitable for symmetric crypto and firmware integrity use cases without ECC acceleration.

What package type and pin count does the LPC5526JEV98Y use?

The LPC5526JEV98Y uses a VFBGA98 package: a 7 mm × 7 mm thin fine-pitch ball grid array with 98 solder balls and 0.5 mm pitch (SOT1982-1). It provides 64 GPIOs, with pin functions configurable via IOCON registers. This package balances high I/O density and compact size - ideal for space-constrained industrial and medical modules where thermal performance and board area are critical.

Which security features are implemented in hardware on the LPC5526JEV98Y?

The LPC5526JEV98Y implements PRINCE flash encryption/decryption, SHA2-AES cryptographic acceleration, Physical Unclonable Function (PUF) for key generation, True Random Number Generator (TRNG), and secure boot with RSA-2048/4096 signature verification - all in dedicated hardware blocks with DMA support. These features operate independently of the CPU core and are enforced by protected memory regions, ensuring robust root-of-trust without software-only dependencies.

Can the LPC5526JEV98Y support both USB full-speed and high-speed simultaneously?

Yes, the LPC5526JEV98Y integrates two independent USB 2.0 controllers: one full-speed (FS) and one high-speed (HS), each with its own on-chip PHY and dedicated DMA controller. This allows concurrent USB device and host operations - for example, acting as a USB CDC device while enumerating as a USB mass storage host - without shared bandwidth or CPU arbitration overhead. The LPC5526JEV98Y supports crystal-less FS operation in device mode.
