Product details
Overview
NXH5104UK/A1Z from NXP Semiconductors is a 4 Mbit serial SPI EEPROM with byte- and page-level write capability, sector-level hardware/software protection, and integrated power management for ultra-low-voltage operation (1.0 V to 2.0 V VDD). It features a 256-byte page write buffer, 10-year data retention, and 500 000 program cycles - deployed in battery-powered medical sensors and portable IoT edge nodes requiring nonvolatile configuration storage.
For engineers reviewing the NXH5104UK/A1Z datasheet, NXH5104UK/A1Z pinout, NXH5104UK/A1Z application, or NXH5104UK/A1Z equivalent, key selection considerations include its wafer-level chip-scale package (WLCSP13), dual-supply SPI interface (VDD up to 2.0 V, VDD(IO) up to 2.6 V), VAUX auxiliary voltage output, and support for both SPI mode 0 and mode 3 at up to 10 MHz.
Technical Context
The NXH5104UK/A1Z implements an SPI slave controller supporting mode 0 (CPOL=0, CPHA=0) and mode 3 (CPOL=1, CPHA=1), with clock speeds up to 5 MHz at 1.2 V signaling and 10 MHz at ≥1.8 V VDD(IO). Its internal architecture includes eight 64 kB sectors, a 256-byte page write buffer with partial-page write support, and adaptive wear-out management across all sectors.
Power management integrates a wide-range supply mode (VDD(IO) ≥ VDD, VDD = 1.0–2.0 V) and fixed high supply mode (VDD ≥ 1.5 V), with dedicated pins for VDD(EE) decoupling and VAUX programmable output. Sector-level power-down (SPD bits in XSR) and configurable read address wrapping (RAWSEC/RAWFULL) enable fine-grained memory access control.

| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD | Primary power supply input | Supplies core logic; invalid voltages cause spurious behavior |

| CS | SPI chip select | Active-low; initiates transactions and wakes device from power-down |
| SO | SPI serial data output | Outputs on SCK falling edge; high-impedance when CS high; requires system pull-up |
| SI | SPI serial data input | Latches on SCK rising edge; referenced to VDD(IO) |

Equivalent & Alternatives
The following parts are listed as comparable options for similar serial SPI EEPROM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AT25DF041A-SSHN-B | 4 Mbit SPI flash; no VAUX output; 2.7–3.6 V supply only; lacks wear-out reporting | Requires external LDO for sub-2.7 V systems; no built-in battery monitoring or auxiliary drive capability | Select when cost-sensitive and operating above 2.7 V with no need for VAUX or endurance telemetry |
| M95M04-DRMN6TP/K | 4 Mbit SPI EEPROM; 1.8–5.5 V supply; no WLCSP package; no VAUX or VDD(EE) pin | Standard SO8 package increases board area; lacks integrated power management for ultra-low-VDD use cases | Select when SO8 footprint is acceptable and system uses 3.3 V rails without battery-direct operation |
Compared with AT25DF041A-SSHN-B and M95M04-DRMN6TP/K, the NXH5104UK/A1Z uniquely supports 1.0 V operation, delivers VAUX for LED/peripheral biasing, and provides real-time wear-out status - making it optimal for space-constrained, battery-critical designs where endurance visibility and minimal external components are essential.

FAQ
What supply configurations does the NXH5104UK/A1Z support?
The NXH5104UK/A1Z supports two supply modes: wide-range mode (VDD = 1.0–2.0 V, VDD(IO) = VDD to 2.6 V) enabled by pulling WRS high, and fixed high supply mode (VDD ≥ 1.5 V) enabled by pulling WRS low. In fixed mode, VDD(EE) must be pulled HIGH via a 1 MΩ resistor to VDD, eliminating the need for an external decoupling capacitor.
How does the NXH5104UK/A1Z handle write protection?
The NXH5104UK/A1Z implements layered write protection: software-based via WEN bit and sector protection bits (SP) in the status register, and hardware-based via the WP pin. When WP is tied to GND, the entire memory array is locked regardless of software settings. Sector-level protection allows independent locking of quarter, half, or full memory - critical for safeguarding calibration data while permitting runtime logging.
Can the NXH5104UK/A1Z operate directly from primary batteries like ZnAir or NiMH?
Yes - the NXH5104UK/A1Z is explicitly designed for direct operation from ZnAir, NiMH, and Silver-Zinc batteries. Its 1.0 V minimum VDD, active peak current limiting, and integrated PMU eliminate the need for intermediate voltage regulation, enabling single-cell battery operation in compact, long-life devices such as disposable medical sensors.
What is the function of the VAUX pin on the NXH5104UK/A1Z?
The VAUX pin on the NXH5104UK/A1Z is a configurable auxiliary voltage output used to drive external components such as status LEDs or low-power analog circuitry. It is programmable via the VAUXCFG register and eliminates the need for discrete voltage sources or current-limiting resistors in space-constrained designs - a feature absent in most competing SPI EEPROMs.
How does wear-out management work in the NXH5104UK/A1Z?
The NXH5104UK/A1Z implements adaptive wear-out management at the page level. When the WOI bit in the extended status register (XSR) is set, the host can issue WOIR followed by RDR to read the 32-bit wear-out status register (WOSR), which flags individual sectors reaching end-of-life. This enables predictive maintenance and graceful degradation handling - unlike conventional EEPROMs that offer no endurance telemetry.
