NXP Semiconductors LPC54605J512ET100E

Overview

LPC54605J512ET100E from NXP Semiconductors is a 32-bit ARM Cortex-M4 microcontroller with FPU and MPU, operating at up to 180 MHz, featuring 512 KB flash, 200 KB SRAM, and dual USB (HS/FS) support. It targets low-power embedded control applications requiring real-time processing, secure boot, and flexible peripheral routing via ten Flexcomm interfaces.

For engineers reviewing the LPC54605J512ET100E datasheet, LPC54605J512ET100E pinout, LPC54605J512ET100E application, or LPC54605J512ET100E equivalent, key selection criteria include TFBGA100 package compatibility, absence of Ethernet AVB and CAN FD, presence of SHA-1/SHA-2 acceleration, and 64 GPIOs with DMA-capable Flexcomm serial peripherals.

Technical Context

The LPC54605J512ET100E implements an ARM Cortex-M4 core (r0p1) with hardware FPU, MPU, and NVIC, executing at 180 MHz using a 3-stage Harvard pipeline with speculative branching. Its clock system integrates a 12 MHz ±1% FRO, system PLL, and independent clocks for USB, ADC, and SPIFI.

Peripheral architecture centers on ten software-configurable Flexcomm interfaces (each selectable as USART/SPI/I2C, two with I2S), a 12-bit 5 MS/s ADC with 12 channels, DMIC subsystem with PDM decimation, SCTimer/PWM with 10 outputs, and a general-purpose DMA controller with 30 channels and 24 triggers.

FAQ

What is the maximum operating frequency of the LPC54605J512ET100E?

The LPC54605J512ET100E operates at a maximum CPU frequency of 180 MHz. This is confirmed in Table 2 of the official NXP datasheet (Rev. 2.8), which specifies "180 MHz" for all LPC54605 devices regardless of flash size or package. The ARM Cortex-M4 core achieves this using the system PLL fed by the internal 12 MHz FRO or external crystal oscillator.

Does the LPC54605J512ET100E support CAN FD or Ethernet AVB?

No, the LPC54605J512ET100E does not support CAN FD or Ethernet AVB. As documented in Table 2 of the NXP datasheet, LPC54605 devices are explicitly defined as HS/FS USB-only variants with no Ethernet or CAN FD functionality. These features appear only in higher-tier variants like LPC54616 and LPC54628.

How many Flexcomm interfaces does the LPC54605J512ET100E provide?

The LPC54605J512ET100E provides ten Flexcomm interfaces (Flexcomm 0 through 9), each configurable in software as USART, SPI, I2C, or I2S (for Flexcomm 0–1 and 5–6). This is stated in Section 2 ("Features and benefits") and confirmed in the block diagram (Figure 4), where ten Flexcomm blocks are shown connected to the AHB matrix.

What is the package type and pin count of the LPC54605J512ET100E?

The LPC54605J512ET100E uses a TFBGA100 package: thin fine-pitch ball grid array with 100 solder balls, body dimensions 9 mm × 9 mm × 0.7 mm, and 0.8 mm ball pitch (SOT926-1). This is explicitly listed in Table 1 ("Ordering information") of the NXP datasheet.

Does the LPC54605J512ET100E include hardware cryptographic acceleration?

Yes, the LPC54605J512ET100E includes a dedicated Secure Hash Algorithm (SHA) module supporting SHA-1 and SHA-2 standards, with its own DMA controller. This is confirmed in Section 2 ("Features and benefits") and Figure 4 (block diagram), where "SHA" appears as a yellow-shaded block with dedicated DMA control.
