NXP Semiconductors LPC54616J512ET100E

Overview

LPC54616J512ET100E from NXP Semiconductors is a 32-bit ARM Cortex-M4 microcontroller operating at up to 180 MHz, featuring 512 KB flash, 200 KB SRAM, dual CAN FD controllers, Ethernet AVB MAC, and USB 2.0 high-speed/full-speed host/device support - deployed in industrial gateways requiring real-time communication, secure firmware updates, and low-power operation.

For engineers reviewing the LPC54616J512ET100E datasheet, LPC54616J512ET100E pinout, LPC54616J512ET100E application, or LPC54616J512ET100E equivalent, key selection criteria include TFBGA100 package compatibility, CAN FD + Ethernet AVB coexistence, 180 MHz deterministic execution, and hardware SHA acceleration for secure boot and OTA updates.

Technical Context

The LPC54616J512ET100E implements an ARM Cortex-M4 core with FPU and MPU, executing at 180 MHz using a 3-stage Harvard pipeline with speculative branching and integrated prefetch unit. It integrates two dedicated DMA controllers - one for general-purpose peripherals and another for CAN FD - enabling concurrent high-bandwidth transfers without CPU intervention.

Its clock system includes a 12 MHz internal FRO trimmed to ±1%, dual PLLs (for USB/audio), and independent peripheral clocks for SPIFI, ADC, and Ethernet. Power management supports deep-sleep and deep power-down modes with wake-up via USART/SPI/I2C slave activity and ultra-low-power Micro-tick Timer running from the watchdog oscillator.

FAQ

What is the maximum operating frequency of the LPC54616J512ET100E?

The LPC54616J512ET100E operates at a maximum CPU frequency of 180 MHz. This is achieved using the system PLL driven by the internal 12 MHz FRO or external crystal. The ARM Cortex-M4 core maintains deterministic timing at this rate, supporting real-time tasks such as CAN FD message scheduling and Ethernet AVB stream handling without jitter degradation. The LPC54616J512ET100E does not support the 220 MHz mode found in the LPC54628 variant.

Does the LPC54616J512ET100E include hardware cryptographic acceleration?

Yes, the LPC54616J512ET100E includes a dedicated Secure Hash Algorithm (SHA) module supporting SHA-1 and SHA-2 (SHA-224/SHA-256) with integrated DMA. This enables high-throughput firmware signature verification during secure boot and OTA updates. Unlike software-only implementations, the hardware SHA engine processes 512-bit blocks in ~200 cycles, reducing CPU load and improving update reliability - a key capability confirmed in the LPC546xx reference manual and UM10912 user guide.

What package type and pin count does the LPC54616J512ET100E use?

The LPC54616J512ET100E uses a TFBGA100 package (SOT926-1) with 100 solder balls arranged in a 9 mm × 9 mm grid at 0.5 mm pitch. Ball A1 is marked in the top-left corner of the package top-side marking. This compact footprint supports high-density PCB layouts in space-constrained industrial modules, and is distinct from the TFBGA180 and LQFP variants in the same family.

Which communication interfaces are supported by the LPC54616J512ET100E?

The LPC54616J512ET100E supports USB 2.0 high-speed and full-speed host/device (with on-chip PHY), dual CAN FD controllers, Ethernet AVB MAC (MII/RMII), ten Flexcomm interfaces (configurable as USART/SPI/I2C/I2S), two Smart Card interfaces, SD/MMC, SPIFI, and I2C Fast-mode Plus (1 Mbit/s). Notably, it omits the LCD controller and SHA module present in the LPC54618 variant, focusing on connectivity rather than display processing.

Is the LPC54616J512ET100E qualified for extended temperature operation?

Yes, the LPC54616J512ET100E is rated for operation from −40 °C to +105 °C ambient temperature and powered from a single 1.71 V to 3.6 V supply. This industrial temperature grade is verified per NXP's qualification standards and supports deployment in harsh environments such as factory floors, outdoor utility cabinets, and transportation infrastructure - without derating or thermal throttling.
