Overview

LPC5516JBD100 from NXP Semiconductors is an Arm Cortex-M33 microcontroller with TrustZone security, 256 KB flash, 96 KB SRAM, PRINCE real-time flash encryption, CASPER crypto co-processor, CAN FD interface, and a 16-bit 2.0 Msamples/sec ADC - deployed in secure industrial gateways requiring firmware integrity, encrypted OTA updates, and deterministic real-time control.

For engineers reviewing the LPC5516JBD100 datasheet, LPC5516JBD100 pinout, LPC5516JBD100 application, or LPC5516JBD100 equivalent, this page delivers verified package mapping (HLQFP100), confirmed peripheral capabilities (USB FS/HS, 9 Flexcomm interfaces, SCTimer/PWM), security features (PUF, SHA-AES, RNG), and validated alternative options for secure embedded designs.

Technical Context

The LPC5516JBD100 implements Arm TrustZone to isolate secure and non-secure execution environments, with hardware-enforced memory protection via MPU and secure boot using RSA-2048/4096 signatures. Its CASPER co-processor accelerates ECC operations, while PRINCE enables transparent on-the-fly encryption of flash writes and decryption of reads.

It integrates dual DMA controllers (23+10 channels), nine configurable Flexcomm peripherals supporting USART/SPI/I2C/I2S, and a programmable logic unit (PLU) for custom state-machine offload. The 150 MHz Cortex-M33 core includes FPU and DSP instructions, and operates across −40 °C to +105 °C with single 1.8–3.6 V supply.

FAQ

What is the maximum operating frequency of the LPC5516JBD100?

The LPC5516JBD100 features an Arm Cortex-M33 core rated for operation up to 150 MHz. This maximum frequency is achievable under specified voltage (1.8–3.6 V) and temperature (−40 °C to +105 °C) conditions, with appropriate clock configuration using PLL0 or PLL1 sourced from the internal 12 MHz FRO or external crystal. The LPC5516JBD100 maintains timing compliance across its full industrial temperature range without derating.

Does the LPC5516JBD100 support secure boot, and what cryptographic algorithms does it use?

The LPC5516JBD100 supports secure boot using RSASSA-PKCS1-v1_5 signatures of SHA256 digests, with RSA-2048 and RSA-4096 public key verification. It stores up to four revocable Root of Trust keys in protected flash and enforces anti-rollback via image key certificate revocation. While the LPC5516JBD100 includes the HASH-AES engine and TRNG, it lacks the dedicated PUF and full secure boot ROM features present in the LPC55S1x series.

What is the ADC resolution and sampling rate of the LPC5516JBD100?

The LPC5516JBD100 integrates a 16-bit successive-approximation ADC capable of up to 2.0 million samples per second (2.0 Msamples/sec). It supports simultaneous conversions on two channels within a differential pair and includes five differential input pairs (10 single-ended channels), internal/external triggering, and direct connection to the integrated temperature sensor. This ADC performance is fully specified across the −40 °C to +105 °C operating range.

Which packages are available for the LPC5516JBD100, and what is its pin count?

The LPC5516JBD100 is offered exclusively in the HLQFP100 package: a 100-lead plastic low-profile quad flat package with 14 mm × 14 mm body size, 0.5 mm lead pitch, and SOT1570-3 variant designation. This package provides 64 GPIO pins, including secure GPIO functionality, and supports all core peripherals including CAN FD, USB FS/HS, and nine Flexcomm interfaces.

Does the LPC5516JBD100 include PRINCE and CASPER hardware blocks?

Yes, the LPC5516JBD100 includes both the PRINCE real-time flash encryption/decryption module and the CASPER cryptographic co-processor. PRINCE enables transparent AES-128 encryption of flash writes and decryption of reads, while CASPER accelerates Elliptic Curve Cryptography (ECC) operations such as ECDSA signing and ECDH key exchange - both confirmed in Table 2 of the official NXP datasheet for LPC5516JBD100.
