NXP Semiconductors LPC5504JBD64E

Overview

LPC5504JBD64 from NXP Semiconductors is a 32-bit ARM Cortex-M33 microcontroller designed for secure embedded control applications. It features 128 KB on-chip flash, 80 KB SRAM, CAN 2.0 interface, 45 GPIOs, and a 16-bit 2.0 Msamples/sec ADC with nine differential input channels. It operates across −40 °C to +105 °C and integrates PRINCE flash encryption and CASPER crypto acceleration.

For engineers reviewing the LPC5504JBD64 datasheet, LPC5504JBD64 pinout, LPC5504JBD64 application, or LPC5504JBD64 equivalent, key selection criteria include its HTQFP64 package, CAN 2.0 (not CAN FD), absence of TrustZone/PUF/Secure Boot, and compatibility with industrial motor control, secure sensor hubs, and low-power gateway nodes requiring deterministic real-time response and hardware-based asset protection.

Technical Context

The LPC5504JBD64 implements an ARM Cortex-M33 core without TrustZone or PUF, running at up to 96 MHz with FPU and MPU support. Its memory subsystem includes 128 KB flash (512-byte page erase) and 80 KB SRAM split across Code Bus (16 KB), System Bus (64 KB contiguous), and additional System Bus (16 KB).

It provides eight Flexcomm interfaces (UART/SPI/I2C/I2S configurable), one dedicated CAN 2.0 controller, five 32-bit general-purpose timers, SCTimer/PWM with 10 outputs, PLU for logic customization, and a 16-bit ADC supporting simultaneous dual-channel sampling at 2.0 Msamples/sec - all operating within a single power domain (1.8–3.6 V) and qualified for extended temperature range.

FAQ

What is the maximum operating frequency of the LPC5504JBD64?

The LPC5504JBD64 runs its ARM Cortex-M33 core at up to 96 MHz, supported by internal PLLs and the 96 MHz Free Running Oscillator (FRO). This frequency is achievable across the full −40 °C to +105 °C temperature range with 1.8–3.6 V supply, and is validated for sustained operation in industrial environments without thermal throttling. The LPC5504JBD64 maintains deterministic timing at this rate for real-time control loops and high-speed serial communication.

Does the LPC5504JBD64 support CAN FD or only CAN 2.0?

The LPC5504JBD64 supports CAN 2.0 only, not CAN FD. This is explicitly confirmed in Table 2 of the datasheet, which lists "CAN2.0" under the CAN FD column for all LPC550x variants including LPC5504JBD64. In contrast, LPC55S0x variants (e.g., LPC55S04JBD64) include CAN FD. The LPC5504JBD64's CAN controller is fully compatible with ISO 11898-1:2015 (Classical CAN) and supports bit rates up to 1 Mbps.

What security features are included in the LPC5504JBD64?

The LPC5504JBD64 includes PRINCE flash encryption, CASPER crypto acceleration (for ECC), HASH-AES engine, TRNG, and 128-bit UUID. It does not include TrustZone, PUF, or Secure Boot - these are exclusive to the LPC55S0x family. The LPC5504JBD64 supports hardware-accelerated AES-128 for runtime flash decryption and ECC signing, enabling secure firmware updates and device authentication without software overhead.

How many ADC channels does the LPC5504JBD64 support, and what is its resolution?

The LPC5504JBD64 integrates a 16-bit successive-approximation ADC with nine differential input channel pairs (or 18 single-ended inputs), capable of simultaneous conversions on two channels within a differential pair. Its maximum sample rate is 2.0 Msamples/sec, and it supports internal/external triggering, programmable gain, and hardware averaging. This ADC configuration is confirmed in Table 2 and Section 2.1 of the datasheet for the LPC5504JBD64 variant.

What is the package type and pin count of the LPC5504JBD64?

The LPC5504JBD64 uses the HTQFP64 package: a plastic low-profile quad flat package with 64 leads, 0.5 mm pitch, and 10 × 10 × 0.5 mm body dimensions. The exposed thermal pad must be connected to VSS for thermal and electrical stability. Pin configuration is documented in Figure 4 and Table 3 of the datasheet, confirming 45 GPIOs, dedicated CAN signals, and dual crystal oscillator inputs (32 MHz and 32.768 kHz).
