For engineers reviewing the LPC54628J512ET180 datasheet, LPC54628J512ET180 pinout, LPC54628J512ET180 application, or LPC54628J512ET180 equivalent, key selection criteria include TFBGA180 package compatibility, 220 MHz CPU performance, dual USB (HS/FS) with on-chip PHYs, AVB-capable Ethernet MAC, and hardware-accelerated cryptographic operations for secure boot and OTA updates.

Technical Context

The LPC54628J512ET180 implements an ARM Cortex-M4 core (r0p1) with Harvard architecture, 3-stage pipeline, and integrated FPU/MPU - enabling deterministic DSP and floating-point execution in motor control and audio processing. Its clock system includes a 12 MHz FRO trimmed to ±1%, dual PLLs (USB/audio), and independent peripheral clocks for ADC, SPIFI, and USB subsystems.

Peripherals are organized around a multilayer AHB matrix with dedicated DMA controllers for Ethernet, CAN FD, LCD, and USB - supporting concurrent high-bandwidth transfers without CPU intervention. The Flexcomm interface architecture allows runtime reconfiguration of up to ten serial peripherals (USART/SPI/I2C/I2S) with shared fractional baud-rate generators and FIFOs.

FAQ

What is the maximum operating frequency of the LPC54628J512ET180?

The LPC54628J512ET180 operates at a maximum CPU frequency of 220 MHz, enabled by its ARM Cortex-M4 core with integrated FPU and MPU. This frequency is achievable using the system PLL driven by the internal 12 MHz FRO or external crystal oscillator. The 220 MHz rating is specific to the LPC54628 variant - other LPC546xx members (e.g., LPC54618) are rated for 180 MHz. Thermal and voltage conditions must meet datasheet specifications (1.71 V–3.6 V, −40 °C to +105 °C) to sustain this speed.

Does the LPC54628J512ET180 support CAN FD and classic CAN simultaneously?

Yes, the LPC54628J512ET180 integrates two independent CAN FD modules, each compatible with ISO 11898-1:2015 and supporting both CAN FD and legacy CAN 2.0 protocols. Both modules operate concurrently - for example, one can handle high-speed firmware updates over CAN FD while the other manages diagnostic messaging via CAN 2.0. Each module has dedicated DMA controllers and separate message RAM, ensuring zero interference between channels.

What package type and pin count does the LPC54628J512ET180 use?

The LPC54628J512ET180 uses a TFBGA180 package (SOT570-3) with 180 solder balls arranged in a 12 mm × 12 mm body at 0.8 mm pitch. This package provides 145 GPIOs and supports high-density routing for complex peripherals including Ethernet AVB, LCD, and dual USB PHYs. Pin assignments follow JEDEC MO-275 standards, with ball A1 marked in the top-left corner of the package top side.

How does the Flexcomm interface architecture work on the LPC54628J512ET180?

The LPC54628J512ET180 features ten Flexcomm interfaces (FC0–FC9), each software-configurable as USART, SPI, I2C, or I2S. Each includes a FIFO, programmable clock dividers, and shared fractional baud-rate generators. Two Flexcomms (FC0, FC1) support I2S, and all support DMA. Configuration is done via the SYSCON register block - for example, FC3 can be set as SPI master while FC4 runs as I2C slave, enabling concurrent sensor communication and display interface control without pin conflicts.

Is hardware cryptographic acceleration available on the LPC54628J512ET180?

Yes, the LPC54628J512ET180 includes a dedicated Secure Hash Algorithm (SHA) module supporting SHA-1 and SHA-2 (SHA-224/SHA-256) with integrated DMA controller. This hardware accelerator performs hash computations independently of the CPU - for instance, verifying firmware image integrity during boot in under 8.3 ms for a 256 KB payload. The SHA engine is accessible via APB bus and requires no software library dependencies, unlike the LPC54618J512ET180 which lacks this block.
