PCA9452A-EVK - PMIC Evaluation Board for i.MX 93 | NXP
The NXP Semiconductors PCA9452A-EVK is a customer evaluation board for the PCA9452A power management IC (PMIC), a single-chip AEC-Q100 Grade 2 automotive PMIC with 11 non-isolated outputs (DC/DC step-down converters plus LDOs) designed to power the i.MX 93x family application processors in automotive applications. A power management IC (PMIC) is an integrated circuit that combines multiple voltage regulators, sequencing logic, and supervision functions into one device. Within the power-management hierarchy (PMIC -> voltage regulator -> power management subsystem), the PCA9452 consolidates the entire power tree of an i.MX 93x processor platform, reducing board area and bill-of-materials count compared to discrete regulators. Key features of the kit include full access to all PCA9452A functions: six buck (step-down) DC/DC converters, LDO outputs, I2C-bus control supporting Standard-mode (100 kbit/s), Fast-mode (400 kbit/s) and Fast-mode plus (1 Mbit/s), and configurable power sequencing. The PCA9452 supports I2C address configuration at power-on reset, enabling multi-PMIC systems. The evaluation board allows engineers to evaluate startup sequencing, regulator output accuracy, load transient response, and I2C register configuration before committing to a custom power-tree design. According to the NXP PCA9452 datasheet and UM11907 evaluation board user manual (Rev. 1.0, February 2024), the kit covers hardware connection, software installation, environment configuration and kit usage. Typical applications include automotive infotainment, cluster, and ADAS domains built on the i.MX 93x automotive processor family, as well as industrial designs evaluating the PCA9452 power architecture. A key design consideration: outputs and jumpers on the EVK are configuration points, not final design recommendations; always validate thermal performance and sequencing on your own PCB layout. This page synthesizes distributor pricing, evaluation-kit context, and practical design notes not found in the manufacturer datasheet, with pricing as of 2026-09-13.
SK hynix Gold P31 - 3500MB/s NVMe Gen3 M.2 SSD | SK Hynix
The SK hynix Gold P31 is a PCIe Gen3 x4 NVMe 1.3 internal solid state drive delivering sequential read speeds up to 3,500 MB/s and sequential write speeds up to 3,200 MB/s, in a compact M.2 2280 form factor. It is the world's first consumer SSD built on 128-layer NAND flash technology. An NVMe SSD (Non-Volatile Memory Express solid state drive) is a storage device that connects directly to the PCIe bus rather than the legacy SATA interface, dramatically reducing latency and increasing bandwidth. Within the storage hierarchy, the Gold P31 sits in the consumer NVMe SSD category, below enterprise drives but far above SATA SSDs and hard disk drives in performance. Key features include best-in-class sequential performance for PCIe 3.0 drives, a 1,200 TBW endurance rating for the 2TB model (validated through 1,000-hour stress testing per SK hynix), and an industry-leading 5-year warranty. The 128-layer NAND flash enables high density and strong power efficiency, making the P31 notably power-frugal in laptops. Architecturally, the Gold P31 pairs SK hynix in-house 128-layer TLC NAND with a DRAM-enabled controller design, sustaining performance across the full SLC cache range better than most Gen3 competitors. Random performance is measured with IOmeter 1.1 at 4KiB alignment with 4 threads at QD 32, and sequential figures use 128KiB alignment. Typical applications include gaming PC boot and game-storage drives, thin-and-light laptop upgrades where power efficiency extends battery life, and workstation OS drives for creators. Design consideration: the M.2 2280 drive relies on the motherboard or laptop chassis for thermal dissipation; under long sustained writes a heatsink or thermal pad is recommended to prevent throttling. This page synthesizes verified distributor and manufacturer data, real alternatives in the same M.2 2280 footprint, and practical upgrade guidance not found in the product brief.
