NXP Semiconductors LPC5514JBD100K

Overview

LPC5514JBD100 from NXP Semiconductors is an Arm Cortex-M33 microcontroller with TrustZone security, 128 KB flash, 80 KB SRAM, PRINCE flash encryption, CASPER crypto acceleration, and CAN FD interface-designed for secure industrial control and IoT edge nodes requiring real-time communication, cryptographic integrity, and low-power operation.

For engineers reviewing the LPC5514JBD100 datasheet, LPC5514JBD100 pinout, LPC5514JBD100 application, or LPC5514JBD100 equivalent, this page delivers verified technical context, package-specific pin mapping, functional alternatives, and supply-ready procurement details-focused on secure boot validation, Flexcomm peripheral configuration, and HLQFP100 layout integration.

Technical Context

The LPC5514JBD100 implements Arm TrustZone to isolate secure and non-secure execution environments, with hardware-enforced memory protection and debug authentication via RSA-2048/4096. Its PRINCE module enables real-time AES-256 encryption/decryption of flash reads and writes without software overhead.

CASPER co-processor accelerates ECC operations for key exchange and digital signatures, while the dual DMA controllers (23+10 channels) support concurrent high-bandwidth transfers across USB HS/FS, CAN FD, and up to nine Flexcomm interfaces-each configurable as USART, SPI, I2C, or I2S with FIFO and fractional baud-rate generation.

FAQ

What is the maximum operating frequency of the LPC5514JBD100?

The LPC5514JBD100 operates at up to 150 MHz using its Arm Cortex-M33 core. This frequency is achievable with PLL0 or PLL1 clock sources derived from the internal 12 MHz FRO, external crystal (12–32 MHz), or 32.768 kHz RTC oscillator-enabling deterministic real-time response for industrial control loops and high-throughput USB/CAN FD data handling within the LPC5514JBD100's power envelope.

Does the LPC5514JBD100 support secure boot, and what cryptographic algorithms does it use?

The LPC5514JBD100 supports secure boot using RSASSA-PKCS1-v1_5 signatures of SHA256 digests, with RSA-2048 and RSA-4096 public keys validated against x509 certificates. It stores up to four revocable Root of Trust keys in protected flash and implements anti-rollback via image key certificate revocation-though unlike the LPC55S1x variant, it lacks TrustZone and PUF-based key derivation, relying instead on software-managed keys for LPC5514JBD100 deployments.

How many Flexcomm interfaces does the LPC5514JBD100 include, and what protocols can they support?

The LPC5514JBD100 integrates nine Flexcomm interfaces (FC0–FC8), each configurable in software as USART, SPI, I2C, or I2S. FC0–FC5 each support one I2S channel pair; FC6–FC7 support four I2S channel pairs. All include FIFOs, fractional baud-rate generators, and timeout detection-enabling mixed-protocol communication stacks (e.g., I2C sensor hub + SPI display + USART debug) without external bridge ICs in the LPC5514JBD100 design.

What is the role of the PRINCE module in the LPC5514JBD100?

The PRINCE module in the LPC5514JBD100 provides real-time AES-256 encryption and decryption of on-chip flash memory during read and write operations. It uses keys stored in secure memory to protect firmware assets and enable authenticated, encrypted over-the-air updates-without CPU intervention or performance penalty-making it essential for protecting intellectual property and ensuring firmware integrity in the LPC5514JBD100's target applications.

What package type and pin count does the LPC5514JBD100 use?

The LPC5514JBD100 uses the HLQFP100 package: a 100-lead plastic low-profile quad flat package with 0.5 mm pitch, 14 mm × 14 mm body size, and exposed thermal pad. This package supports standard PCB assembly processes and provides sufficient I/O (64 GPIOs) and routing flexibility for complex industrial and IoT designs requiring CAN FD, USB HS/FS, and multiple serial interfaces in the LPC5514JBD100 implementation.
