NXP Semiconductors LPC5514JEV59E

Overview

LPC5514JEV59E from NXP Semiconductors is a 32-bit Arm Cortex-M33 microcontroller with TrustZone security, 128 KB flash, 80 KB SRAM, PRINCE flash encryption, CASPER crypto co-processor, CAN FD interface, and high-speed USB (HS only), deployed in secure industrial control and IoT edge nodes requiring tamper-resistant firmware execution and real-time analog sensing.

For engineers reviewing the LPC5514JEV59E datasheet, LPC5514JEV59E pinout, LPC5514JEV59E application, or LPC5514JEV59E equivalent, key selection criteria include VFBGA59 package footprint, 37 GPIO count, absence of full-speed USB (FS), lack of Secure Boot and PUF support versus S-series variants, and compatibility with LPC551x family toolchains and SDKs.

Technical Context

The LPC5514JEV59E implements Arm TrustZone for hardware-enforced memory isolation between secure and non-secure worlds, enabling secure boot partitioning and cryptographic key protection. Its CASPER co-processor accelerates ECC operations, while PRINCE provides real-time AES-128 encryption/decryption of on-chip flash contents during read/write cycles.

It integrates nine Flexcomm interfaces configurable as USART, SPI, I2C, or I2S-Flexcomm 8 dedicated to high-speed SPI-with DMA support across peripherals including CAN FD, SCTimer/PWM, and a 16-bit 2.0 Msamples/sec ADC supporting simultaneous differential conversions. The device lacks full-speed USB and Secure Boot features present in LPC55S1x variants.

FAQ

Does LPC5514JEV59E support Secure Boot?

No, LPC5514JEV59E does not include Secure Boot capability. Unlike the LPC55S1x series, this variant omits the ROM bootloader features required for cryptographic image verification, RSA key handling, and x.509 certificate validation. The LPC5514JEV59E relies on external secure elements or software-only authentication if firmware integrity enforcement is required. Designers must verify boot flow requirements against the LPC5514JEV59E datasheet Section 2.3 and select LPC55S1x variants for hardware-enforced Secure Boot.

What USB modes does LPC5514JEV59E support?

LPC5514JEV59E supports high-speed (HS) USB 2.0 host and device operation only, with an integrated HS PHY. It does not include a full-speed (FS) USB PHY or crystal-less FS operation capability. This means LPC5514JEV59E cannot function as a USB FS device without external transceiver hardware, and cannot enumerate as a HID or CDC device in FS mode. All USB communication must operate at 480 Mbps using the HS PHY and associated DMA controllers.

Is the PRINCE module functional on LPC5514JEV59E?

Yes, the PRINCE module is fully operational on LPC5514JEV59E. It provides real-time AES-128 encryption and decryption of on-chip flash memory during read and write operations, protecting firmware assets and enabling secure over-the-air updates. PRINCE operates transparently to software and requires no CPU cycles-flash access latency remains unchanged. Configuration is performed via dedicated PRINCE registers in the system control block, and keys are stored in protected memory regions.

How many GPIO pins are available on LPC5514JEV59E?

LPC5514JEV59E provides 37 usable GPIO pins in its VFBGA59 package. This count excludes power, ground, reset, and dedicated debug pins (SWD_DIO, SWD_CLK), and reflects only pins configurable as general-purpose digital inputs/outputs. Each GPIO supports multiple functions via IOCON registers-including UART, SPI, I2C, ADC, comparator, and secure GPIO modes-and up to eight can be configured as pin interrupts with edge sensitivity.

What is the maximum ADC sampling rate supported by LPC5514JEV59E?

LPC5514JEV59E supports a maximum ADC sampling rate of 2.0 million samples per second (2.0 Msamples/sec) using its 16-bit successive approximation register (SAR) ADC. This rate applies to single-channel operation; simultaneous sampling across differential pairs maintains timing coherence but does not increase aggregate throughput. The ADC includes five differential input pairs (10 single-ended channels), internal temperature sensor, and hardware trigger synchronization with timers and PWM modules.
