Product details
Overview
LPC55S66JEV98K from NXP Semiconductors is a dual-core ARM Cortex-M33 microcontroller with TrustZone security, CASPER crypto co-processor, and PowerQuad DSP accelerator. It delivers up to 150 MHz CPU0 operation, 256 KB flash, 144 KB SRAM, PRINCE real-time flash encryption, and supports USB Full-Speed/High-Speed, SDIO, and nine Flexcomm serial interfaces. It targets secure industrial control, IoT edge nodes, and trusted firmware execution environments.
For engineers reviewing the LPC55S66JEV98K datasheet, LPC55S66JEV98K pinout, LPC55S66JEV98K application, or LPC55S66JEV98K equivalent, key selection considerations include dual-core TrustZone isolation, PRINCE-encrypted flash, PUF-based key generation, 16-bit 1.0 Msamples/sec ADC with simultaneous differential conversion, and VFBGA98 package compatibility with high-density PCB layouts.
Technical Context
The LPC55S66JEV98K integrates two ARM Cortex-M33 cores: CPU0 (150 MHz, with MPU, FPU, TrustZone, ETM) for secure application execution, and CPU1 (150 MHz, no MPU/FPU/TrustZone) for offloading real-time or cryptographic tasks. Its CASPER engine accelerates ECC operations, while PowerQuad hardware executes CMSIS-DSP functions at accelerated throughput via dedicated DMA paths.
Security architecture includes PRINCE for on-the-fly flash encryption/decryption, PUF-generated 64–4096-bit keys, SHA2/AES-256 engines with dedicated DMA, DICE-compliant device identity composition, and Secure Boot with RSA-2048/4096 signature verification against x.509 certificates and anti-rollback image revocation.

FAQ
What is the maximum operating frequency of the LPC55S66JEV98K primary core?
The LPC55S66JEV98K primary core (CPU0) operates at up to 150 MHz, confirmed for device revision 1B per NXP's official datasheet Rev. 2.4. This frequency is achievable using PLL0 or PLL1 clock sources derived from internal FRO, external crystal, or RTC oscillator. The LPC55S66JEV98K does not support 200 MHz operation.
Does the LPC55S66JEV98K support USB High-Speed functionality?
Yes, the LPC55S66JEV98K integrates a USB 2.0 High-Speed host/device controller with an on-chip high-speed PHY, supporting 480 Mbps operation. It also includes a separate USB 2.0 Full-Speed controller with crystal-less device-mode capability. Both controllers have dedicated DMA channels and are fully functional in the VFBGA98 package.
How does the PRINCE module function in the LPC55S66JEV98K?
The PRINCE module in the LPC55S66JEV98K performs real-time AES-128 encryption of data written to flash and decryption of data read from flash-transparently, without software intervention. It protects application code and configuration assets in the 256 KB flash, and is enabled via protected flash region (PFR) settings. The LPC55S66JEV98K implements PRINCE as specified in NXP's LPC55S6x reference manual.
What analog peripherals are integrated into the LPC55S66JEV98K?
The LPC55S66JEV98K integrates a 16-bit, 1.0 Msamples/sec ADC with five differential or ten single-ended input channels, an analog comparator with five inputs and selectable reference, and an on-die temperature sensor connected to the ADC. All analog functions are accessible through dedicated pins (e.g., PIO0_10/ADC0_1, PIO0_11/ADC0_9) and support simultaneous dual-channel conversion.
Is the LPC55S66JEV98K pin-compatible with other LPC55S6x variants in VFBGA98?
Yes, the LPC55S66JEV98K shares identical pinout, ball assignment, and electrical characteristics with LPC55S69JEV98 and LPC55S66JEV98 (non-K suffix) in the VFBGA98 package (SOT1982-1). The 'K' suffix denotes tape-and-reel packaging per NXP's ordering conventions and does not affect pin functionality or compatibility.
