NXP Semiconductors LPC5512JBD100Y

Overview

LPC5512JBD100Y from NXP Semiconductors is a 32-bit Arm Cortex-M33 microcontroller designed for secure embedded control applications. It operates at up to 150 MHz, integrates 64 KB flash and 48 KB SRAM, features CAN 2.0 (not CAN FD), full-speed USB, and a 16-bit 2.0 Msamples/sec ADC with simultaneous conversion capability - deployed in industrial sensor nodes requiring deterministic real-time response and firmware integrity.

For engineers reviewing the LPC5512JBD100Y datasheet, LPC5512JBD100Y pinout, LPC5512JBD100Y application, or LPC5512JBD100Y equivalent, key selection criteria include its HLQFP100 package with 100 leads, TrustZone®-enabled security foundation, PRINCE flash encryption support, CASPER crypto acceleration, and compatibility with NXP's MCUXpresso SDK for secure boot and peripheral configuration.

Technical Context

The LPC5512JBD100Y implements Arm TrustZone® for hardware-enforced memory and peripheral isolation, enabling secure firmware execution alongside non-secure application code. Its CASPER co-processor accelerates ECC-based asymmetric cryptography, while PRINCE provides real-time on-the-fly AES-128 encryption/decryption of flash contents during read/write operations.

It integrates two DMA controllers (23-channel DMA0 and 10-channel DMA1), nine Flexcomm interfaces configurable as USART/SPI/I²C/I²S, and a programmable SCTimer/PWM with 16 capture/match registers. The device lacks TrustZone®, PUF, Secure Boot, HASH-AES, and CASPER - confirmed by Table 2 ordering options - distinguishing it from LPC55S1x variants.

Key Specifications

Equivalent & Alternatives

The following parts are listed as comparable options for similar microcontroller applications.

Compared with LPC5514JBD100, the LPC5512JBD100 trades flash/SRAM capacity for lower unit cost and footprint-equivalent integration; compared with LPC55S12JBD100, it omits security accelerators to reduce silicon area and power consumption - making it optimal for cost-sensitive, non-certified industrial control where deterministic timing outweighs cryptographic requirements.

Availability

LPC5512JBD100Y is available at Aetrix Electronics and suitable for industrial sensor nodes, smart energy meters, secure gateway controllers, and motor control edge nodes requiring stable component supply across extended temperature ranges and long production lifecycles.

Supply support for LPC5512JBD100Y includes scheduled delivery planning, volume procurement assistance, BOM continuity management, traceable sourcing, and lifecycle availability coordination for OEM customers, industrial embedded developers, connected-device designers, and electronics production programs.

Manufacturer

NXP Semiconductors is a global semiconductor leader specializing in secure connectivity solutions for automotive, industrial, and IoT applications, with headquarters in Eindhoven, Netherlands.

The LPC551x series targets cost-optimized, real-time embedded control applications where deterministic performance, analog integration, and industrial-grade reliability are prioritized over advanced security features - distinguishing it from the security-focused LPC55S1x family.

FAQ

What is the maximum operating frequency of the LPC5512JBD100Y?

The LPC5512JBD100Y operates at a maximum CPU frequency of 150 MHz, enabled by its Arm Cortex-M33 core with integrated FPU and DSP instructions. This clock speed is achievable using internal PLLs driven by the 12 MHz FRO or external crystal sources. The device maintains timing integrity across its full industrial temperature range of −40 °C to +105 °C, and the LPC5512JBD100Y datasheet specifies stable operation under all supported voltage conditions (1.8 V to 3.6 V).

Does the LPC5512JBD100Y support CAN FD or only classical CAN?

The LPC5512JBD100Y supports only CAN 2.0 (Classical CAN) with bit rates up to 1 Mbps, as confirmed in Table 2 of the official NXP datasheet. It does not include the CAN FD module present in LPC55S1x and higher-tier LPC551x variants. The CAN0_TD and CAN0_RD pins on the HLQFP100 package are functionally limited to ISO 11898-1 compliance, and no CAN FD-specific registers or DMA channels are implemented in the LPC5512JBD100Y silicon.

What security features are included in the LPC5512JBD100Y?

The LPC5512JBD100Y includes PRINCE flash encryption and basic Code Watchdog for runtime code flow integrity, but excludes TrustZone®, PUF, Secure Boot, HASH-AES, CASPER, and DICE - all explicitly marked as "–" in Table 2 of the NXP datasheet. Its security model centers on firmware IP protection via PRINCE and deterministic execution monitoring, making it suitable for applications where cryptographic acceleration or certified secure boot is not required.

Which development tools are officially supported for the LPC5512JBD100Y?

NXP officially supports the LPC5512JBD100Y with MCUXpresso IDE, SDK, and Config Tools - including drivers for Flexcomm, SCTimer/PWM, ADC, and USB FS. Hardware debugging uses standard SWD via LPC-Link2 or J-Link probes. The LPC5512JBD100Y is compatible with the LPCXpresso55S16 development board for evaluation, though users must disable S1x-specific features (e.g., PUF, CASPER) in software to match LPC5512JBD100Y capabilities.

What is the ADC resolution and sampling rate of the LPC5512JBD100Y?

The LPC5512JBD100Y integrates a 16-bit successive-approximation ADC capable of 2.0 million samples per second (2.0 Msamples/sec), with support for simultaneous conversions on paired differential channels. It provides 10 single-ended or 5 differential input channels, internal temperature sensor integration, and multiple trigger sources including timers and external pins - all documented in the LPC55S1x/LPC551x product data sheet Rev. 1.8.
