Product details
Overview
LPC5528JBD64K from NXP is a 150 MHz Arm Cortex-M33 microcontroller with 512 KB flash, 256 KB SRAM, dual USB (FS + HS) with on-chip PHY, SDIO interface, and HTQFP64 package - designed for secure industrial IoT edge nodes requiring real-time control and low-power operation.
For engineers reviewing the LPC5528JBD64K datasheet, LPC5528JBD64K pinout, LPC5528JBD64K application, or LPC5528JBD64K equivalent, key selection criteria include USB/SDIO connectivity, absence of crypto acceleration and secure boot features versus LPC55S2x variants, and HTQFP64 footprint compatibility in space-constrained embedded designs.
Technical Context
The LPC5528JBD64K implements an Arm Cortex-M33 core without TrustZone support and lacks hardware AES-256/SHA-2 acceleration, PRINCE encryption engine, and SRAM PUF - distinguishing it from LPC55S2x siblings. It retains full FlexComm (8× configurable UART/SPI/I²C/I²S), SCTimer/PWM, and high-speed USB + SDIO interfaces.
Its clock system includes System PLL, USB PLL, and multiple oscillators; power management supports single VDD, POR/BOD, and reduced-power modes with integrated DC-DC converter - enabling deterministic real-time execution at 150 MHz while maintaining sub-100 µA sleep current.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LPC55S28JBD64K | Includes AES-256/SHA-2 crypto engine, PRINCE real-time decryption, SRAM PUF, and secure boot ROM - absent in LPC5528JBD64K | Required for firmware signing, encrypted OTA, and root-of-trust provisioning in certified medical/industrial devices | Select when cryptographic integrity and secure lifecycle management are mandatory - adds ~$0.80 cost and requires TrustZone-aware software stack |
| LPC5526JBD64K | Same core and peripherals but reduced memory: 256 KB flash / 144 KB SRAM - no crypto or secure boot features | Suitable for cost-sensitive applications with smaller firmware footprints (e.g., basic sensor nodes) | Choose for lower-cost deployment where full 512 KB flash and 256 KB SRAM headroom are unnecessary |
Compared with LPC55S28JBD64K, the LPC5528JBD64K trades security hardware for lower unit cost and simpler certification; compared with LPC5526JBD64K, it offers 100% more flash and 77% more SRAM - critical for complex protocol stacks and future firmware expansion.

FAQ
Does LPC5528JBD64K support Arm TrustZone technology?
No, the LPC5528JBD64K does not implement Arm TrustZone. Unlike the LPC55S2x series, this variant omits TrustZone, secure boot ROM, and hardware cryptographic accelerators. Its security model relies on software-based isolation and external secure elements if required. The LPC5528JBD64K datasheet explicitly states "no TrustZone support" in the feature summary table.
What is the maximum operating frequency of LPC5528JBD64K?
The LPC5528JBD64K operates at a maximum CPU frequency of 150 MHz, achieved via its System PLL driven by an external crystal or internal RC oscillator. This frequency is sustained across the full industrial temperature range (–40°C to +105°C) with appropriate VDD and thermal management. All timing-critical peripherals, including USB and SDIO, are fully functional at 150 MHz in the LPC5528JBD64K.
Can LPC5528JBD64K boot from SDIO or USB mass storage?
Yes, the LPC5528JBD64K supports booting from SDIO-connected eMMC or SD cards using its dedicated SDIO controller. It also supports USB device-mode boot via the built-in USB HS/FS PHY - allowing firmware loading from a host PC without external bootloader hardware. Boot source selection is configured via dedicated pins at reset, and the LPC5528JBD64K ROM bootloader handles initialization.
Is there a hardware random number generator in LPC5528JBD64K?
No, the LPC5528JBD64K does not include a hardware RNG. Unlike the LPC55S2x series, which integrates a TRNG module compliant with NIST SP 800-90B, the LPC5528JBD64K omits this block. Applications requiring entropy must use software-based PRNGs seeded from external sources or add discrete RNG ICs. This omission is consistent across all LPC552x non-S variants per the LPC552xFAMFS datasheet.
What development boards are compatible with LPC5528JBD64K?
The LPCXpresso55S28 (LPC55S28-EVK) is the officially supported evaluation board for the LPC552x family, including the LPC5528JBD64K. Though populated with an LPC55S28, its pin-compatible HTQFP64 footprint, identical peripheral mapping, and MCUXpresso SDK support make it fully usable for LPC5528JBD64K firmware development and validation.
