Product details
Overview
CY15V104QN-50LPXIT from Infineon is a 4-Mb serial ferroelectric RAM (F-RAM) organized as 512K × 8, operating on SPI interface at up to 50 MHz with 1.71–1.89 V supply, 10¹⁵ write endurance, and 151-year data retention. It serves as nonvolatile memory in real-time data logging systems where rapid, reliable byte-level writes are critical.
For engineers reviewing the CY15V104QN-50LPXIT datasheet, CY15V104QN-50LPXIT pinout, CY15V104QN-50LPXIT application, or CY15V104QN-50LPXIT equivalent, key selection criteria include industrial temperature support (–40°C to +85°C), hardware/software write protection, dedicated 256-byte special sector for reflow-survivable configuration storage, and drop-in compatibility with SPI EEPROM/flash footprints.
Technical Context
The CY15V104QN-50LPXIT implements an SPI slave interface compliant with modes 0 (CPOL=0, CPHA=0) and 3 (CPOL=1, CPHA=1), supporting continuous read/write transfers without polling or erase cycles. Its ferroelectric memory array enables true instant-write behavior - data commits immediately upon byte transfer completion, eliminating latency inherent in flash/EEPROM programming.
It integrates a nonvolatile status register with WPEN bit control, hardware write protect (WP pin), software block protection (1/4, 1/2, or full array), Device ID (manufacturer + product ID), unique ID, and 8-byte user-writable serial number. The dedicated 256-byte special sector retains data across up to three standard reflow soldering cycles.

Equivalent & Alternatives
The following parts are listed as comparable options for similar nonvolatile serial memory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CY15B104QN-50LPXIT | Wider VDD range (1.8–3.6 V); identical pinout, timing, and command set; higher active current at 3.3 V | Preferred for mixed-voltage systems or legacy 3.3 V designs; not suitable for strict 1.8 V-only rails | Select when board already uses 3.3 V supply or requires backward compatibility with older 3.3 V SPI peripherals |
| AT25DF041A-MAHN-T | 4 Mb SPI flash; requires page erase (20 ms), 100k write cycles, 20-year retention; 3.3 V only | Lower cost but unsuitable for frequent-write scenarios; requires firmware erase management and wear leveling | Choose only for infrequent configuration storage where cost dominates over write speed and endurance |
Compared with CY15B104QN-50LPXIT, the CY15V104QN-50LPXIT offers tighter voltage tolerance for 1.8 V systems and lower active current, while AT25DF041A demands erase-cycle handling and provides <0.01% the write endurance - making it unfit for real-time logging or high-cycle telemetry.

FAQ
Is CY15V104QN-50LPXIT pin-compatible with standard SPI EEPROMs like AT25XXX series?
Yes - it uses identical 8-pin SOIC packaging and SPI command structure (including Read, Write, WREN, WRDI, RDSR), enabling direct PCB footprint replacement. However, it omits the need for erase commands and status polling, simplifying firmware integration without modifying layout or routing.
Does the 256-byte special sector require separate addressing or initialization?
No - the special sector resides at fixed address range 0x7F000–0x7F0FF and is accessed using standard Read/Write opcodes (0x03/0x02). It requires no initialization or configuration; its reflow survivability is inherent to the ferroelectric process and physical layout, not firmware-controlled.
What happens if the WP pin is left floating during operation?
Leaving WP floating violates the datasheet requirement and risks unintended status register writes. When WPEN=1, floating WP may cause metastability, permitting accidental writes to protected registers. The datasheet mandates tying WP to VDD if unused - this disables hardware write protection and ensures deterministic behavior.
Can CY15V104QN-50LPXIT operate reliably at 50 MHz across the full industrial temperature range?
Yes - the datasheet specifies AC switching characteristics (tSU, tH, tV) validated from –40°C to +85°C at 50 MHz. Timing margins remain sufficient under worst-case voltage (1.71 V) and temperature conditions, with no derating required for maximum clock frequency in industrial environments.
