Product details
Overview
CY15V104QN50BFXIXQLA1 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 instant write, low power, and industrial temperature operation (–40°C to +85°C) are critical.
For engineers reviewing the CY15V104QN50BFXIXQLA1 datasheet, CY15V104QN50BFXIXQLA1 pinout, CY15V104QN50BFXIXQLA1 application, or CY15V104QN50BFXIXQLA1 equivalent, this page delivers verified technical context, SPI timing behavior, write-protection architecture, special sector usage, and drop-in replacement guidance versus serial EEPROM/flash.
Technical Context
The CY15V104QN50BFXIXQLA1 implements an SPI slave interface supporting modes 0 (CPOL=0, CPHA=0) and 3 (CPOL=1, CPHA=1), with zero-latency writes-no polling required-and full bus-speed data transfer. Its internal F-RAM array eliminates erase cycles and enables byte-level writes without wear leveling.
It integrates a nonvolatile status register with WPEN bit, hardware write protection via active-low WP pin, software block protection (1/4, 1/2, or full array), and dedicated 256-byte special sector surviving three reflow cycles. Device ID and 8-byte programmable serial number support secure identification and traceability.
Key Specifications

Pinout & Package
Package: 8-pin SOIC (Small Outline Integrated Circuit), RoHS-compliant, industrial-grade plastic body with standard JEDEC MS-012AC footprint.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| CS | Chip Select input | Active-low enable; places device in standby when HIGH, tristates SO, and halts all internal activity |
| SCK | Serial clock input | Synchronizes all SPI transfers; rising edge latches SI, falling edge drives SO; supports 0–50 MHz with interrupt tolerance |
| SI | Serial input | Receives opcodes, addresses, and write data; must be driven to valid logic level to meet IDD specs |
| SO | Serial output | Drives read data during read operations only; tristated otherwise; transitions on SCK falling edge |
| WP | Write protect input | Hardware lock for status register when WPEN = 1; must tie to VDD if unused to prevent accidental protection |
| VSS | Ground | Reference return path for all signals and power; requires low-impedance connection to system ground plane |
| VDD | Power supply | 1.71–1.89 V input; powers core logic and F-RAM array; bypass capacitor required per datasheet layout guidelines |
| DNU | Do-not-use terminal | No internal connection; must float or tie to VDD-never drive externally or connect to signal nets |
Key Features
| Feature | Design Value |

Equivalent & Alternatives
The following parts are listed as comparable options for similar nonvolatile serial memory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CY15B104QN50SFXI | Wider VDD range (1.8–3.6 V); same density, timing, and F-RAM architecture | Better suited for mixed-voltage systems (e.g., 3.3 V host with 1.8 V peripherals) | Select when system lacks tight 1.71–1.89 V regulation or shares rail with 3.3 V logic |
| AT45DB041E-SHN-B | 4 Mb serial DataFlash; requires erase-before-write, 100k endurance, 20-year retention | Lacks instant write and endurance; needs firmware wear leveling and polling loops | Only consider for cost-sensitive legacy designs where write frequency < 1000×/day and latency tolerance > 5 ms |
Compared with CY15B104QN50SFXI, the CY15V104QN50BFXIXQLA1 offers tighter voltage control for ultra-low-power 1.8 V systems; versus AT45DB041E-SHN-B, it eliminates erase latency and extends field life by 15× via superior endurance and retention-critical for safety-critical or high-write-rate deployments.

FAQ
Is CY15V104QN50BFXIXQLA1 pin-compatible with standard SPI EEPROMs or flash devices?
Yes-it uses an industry-standard 8-pin SOIC package with identical CS/SCK/SI/SO/WP/VSS/VDD pin assignments and SPI command set compatibility (e.g., WREN, WRDI, READ, WRITE). However, unlike EEPROM/flash, it requires no WIP polling and supports continuous write streaming without inter-byte delays.
What is the function of the DNU pin, and how should it be handled on the PCB?
The DNU (Do Not Use) pin has no internal connection. Per Infineon's datasheet, it must either remain unconnected (floating) or be tied to VDD-never driven by external logic or grounded. Incorrect handling may cause undefined behavior or increased leakage current.
Does the 256-byte special sector require separate addressing or special commands?
Yes-the special sector resides at fixed address 0x7F000–0x7F0FF and is accessed using dedicated opcodes (0x77 for read, 0x76 for write). It operates independently of main array protection settings and retains data through multiple reflow cycles due to hardened metallization.
How does write protection work when both WP pin and status register bits are enabled?
Hardware WP takes precedence: when WP is LOW and WPEN=1 in the status register, writes to the status register-including BP bits-are blocked regardless of software commands. This dual-layer scheme prevents accidental override of block protection during firmware updates or field service.
