Overview

LPC5514JBD100Y 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, and CAN FD interface-designed for secure industrial control, IoT edge nodes, and automotive body electronics requiring real-time operation and firmware integrity.

For engineers reviewing the LPC5514JBD100Y datasheet, LPC5514JBD100Y pinout, LPC5514JBD100Y application, or LPC5514JBD100Y equivalent, this page delivers verified technical context, validated pin functions for HLQFP100, confirmed security features (PUF, SHA-AES, secure boot), and precise alternative part comparisons-not generic MCU summaries.

Technical Context

The LPC5514JBD100Y implements Arm TrustZone to isolate secure and non-secure execution environments, with hardware-enforced memory protection and debug authentication using RSA-2048/4096. Its CASPER co-processor accelerates ECC operations, while PRINCE enables real-time on-the-fly AES-256 encryption/decryption of flash contents during read/write.

It integrates nine Flexcomm interfaces (USART/SPI/I2C/I2S configurable per channel), dual DMA controllers (23+10 channels), a 16-bit 2.0 Msamples/sec ADC with simultaneous differential conversion, and a programmable logic unit (PLU) for custom combinatorial logic-enabling deterministic peripheral offloading without CPU intervention.

FAQ

What is the maximum operating frequency of the LPC5514JBD100Y core?

The LPC5514JBD100Y features an Arm Cortex-M33 core rated for operation up to 150 MHz. This maximum frequency is achievable using internal PLLs driven by the 96 MHz Free Running Oscillator (FRO) or external crystal sources. The FRO is factory-trimmed to ±1% accuracy across 0°C to 85°C, ensuring stable timing without external components for many applications. The LPC5514JBD100Y maintains this performance within its specified 1.8 V to 3.6 V supply range and −40°C to +105°C operating temperature.

Does the LPC5514JBD100Y support secure boot with public-key validation?

Yes, the LPC5514JBD100Y supports secure boot using RSASSA-PKCS1-v1_5 signatures of SHA256 digests, with validation against RSA-2048 or RSA-4096 public keys stored in x509 certificate format. It implements up to four revocable Root of Trust keys in protected flash and supports anti-rollback via image key certificate revocation. While it lacks the full TrustZone and PUF features of the LPC55S1x variant, its secure boot engine remains functionally identical and compliant with NXP's SB2 file format version 2.0.

What analog peripherals are integrated into the LPC5514JBD100Y?

The LPC5514JBD100Y integrates a 16-bit ADC capable of 2.0 Msamples/sec sampling with five differential channel pairs (10 single-ended inputs), an analog comparator with five input pins and selectable reference, and an on-die temperature sensor connected directly to the ADC. All analog functions operate from dedicated VDDA/VSSA supplies and support hardware-triggered conversions synchronized to timers or peripherals-enabling precise, low-latency sensor acquisition without CPU polling.

Can the LPC5514JBD100Y use CAN FD in automotive networks?

Yes, the LPC5514JBD100Y includes a fully compliant CAN FD controller supporting data rates up to 5 Mbit/s in fast-phase mode and protocol extensions including flexible data length (up to 64 bytes) and improved error detection. It operates across the full −40°C to +105°C temperature range and integrates a dedicated DMA controller for zero-CPU-load message buffering-making it suitable for automotive body control modules, gateway ECUs, and diagnostic interfaces requiring robust, high-throughput vehicle network communication.

What package type and pin count does the LPC5514JBD100Y use?

The LPC5514JBD100Y uses the HLQFP100 package: a plastic low-profile quad flat package with 100 leads, 14 mm × 14 mm body size, and 0.5 mm lead pitch. It includes an exposed thermal pad for enhanced heat dissipation and is compatible with standard QFP reflow profiles. Pin numbering follows JEDEC MS-026, with Pin 1 located at the top-left corner adjacent to the index mark-matching the footprint of LPC55S1x and LPC551x variants in the same package variant.
