Product details
Overview
CY15V116QSN-108BKXI from Infineon Technologies is a 16-Mbit serial (SPI) F-RAM memory IC with 108 MHz maximum clock frequency, 1.7–2.2 V supply voltage, and -40°C to +105°C industrial temperature range. It serves as non-volatile data storage in real-time metering, PLC I/O modules, and industrial sensor nodes where write endurance and fast write latency are critical.
For engineers reviewing the CY15V116QSN-108BKXI datasheet, CY15V116QSN-108BKXI pinout, CY15V116QSN-108BKXI application, or CY15V116QSN-108BKXI equivalent, key selection criteria include SPI interface timing compliance, 10⁶⁴ write-cycle endurance, zero write-delay architecture, and industrial-grade thermal stability.
Technical Context
This F-RAM integrates a ferroelectric capacitor array with standard SPI serial interface logic, supporting standard, dual, and quad I/O protocols. It operates without internal write buffers or erase cycles, enabling byte-level writes at bus speed and eliminating wear leveling overhead.
The device uses a 16-pin SOIC-N package with exposed pad, supports hold and write-protect pins for hardware-based access control, and features automatic power-on reset with ready/busy status reporting via the /RDY pin.

Equivalent & Alternatives
The following parts are listed as comparable options for similar non-volatile serial memory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CY15B116QSN-108BZI | Same 16-Mbit F-RAM core but rated for -40°C to +125°C; higher max junction temp (150°C) | Required for under-hood automotive ECUs or high-ambient industrial enclosures | Select when ambient exceeds +105°C or AEC-Q100 Grade 1 qualification is mandatory |
| AT25DF161-AU | 16-Mbit NOR Flash with 3V supply, 85 MHz max clock, and 100k write cycles | Lacks true byte-write capability; requires sector erase before reprogramming | Only suitable where infrequent firmware updates dominate over frequent data logging |
Compared with CY15B116QSN-108BZI, this part trades extended temperature margin for lower cost and identical industrial qualification; versus AT25DF161-AU, it delivers 10⁹× greater write endurance and eliminates erase latency, making it irreplaceable in high-frequency data capture systems.

FAQ
Is CY15V116QSN-108BKXI pin-compatible with CY15B116QSN-108BZI?
Yes - both devices share identical 16-pin SOIC-N (300 mil) mechanical footprint, pin assignment, and SPI command set. The only differences are temperature rating and thermal pad specification; no PCB redesign is required for drop-in replacement within the -40°C to +105°C operating range.
Does this F-RAM require external high-voltage programming circuitry?
No - CY15V116QSN-108BKXI performs all write operations using standard 1.7–2.2 V supply voltage. Unlike EEPROM or Flash, it requires no charge pump, no erase pulses, and no special programming voltages, simplifying power design and reducing BOM count.
Can /RDY pin be left unconnected in simple polling-based systems?
Yes - the /RDY pin is optional. When unused, firmware must implement fixed-delay polling after each write command. However, connecting /RDY enables interrupt-driven write completion detection, reducing CPU load and improving system determinism in real-time applications.
What SPI modes does CY15V116QSN-108BKXI support?
It supports SPI Modes 0 (CPOL=0, CPHA=0) and 3 (CPOL=1, CPHA=1) for standard I/O, plus dual and quad I/O variants in both modes. All modes use the same command set; mode selection is determined solely by host controller configuration, not device register settings.
