Product details
Overview
CY15V102QSN-108SXIT from Infineon is a 2-Mbit serial quad SPI ferroelectric RAM (F-RAM) organized as 256K × 8, operating at up to 108 MHz SDR or 54 MHz DDR, with 1.71–1.89 V supply, −40°C to +85°C industrial temperature range, and 100 trillion (10¹⁴) read/write endurance-used for high-frequency data logging in programmable logic controllers.
For engineers reviewing the CY15V102QSN-108SXIT datasheet, CY15V102QSN-108SXIT pinout, CY15V102QSN-108SXIT application, or CY15V102QSN-108SXIT equivalent, key selection factors include instant non-volatile write capability, on-die ECC/CRC support, quad SPI interface timing compliance, and SOIC-8 package compatibility with legacy PCB footprints.
Technical Context
The CY15V102QSN-108SXIT implements a true RAM-like interface over quad SPI (QPI), supporting both SDR and DDR modes with SPI modes 0 and 3. Its ferroelectric memory array eliminates write latency and polling, enabling byte-level writes at bus speed without erase cycles.
It integrates dedicated 256-byte special sector F-RAM survivable through three reflow cycles, on-die ECC correcting 1-bit errors per 8-byte unit and reporting 2-bit errors, plus CRC for full-array data integrity verification-critical for deterministic real-time systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Density | 2 Mbit (256K × 8), directly addressable without page/sector management overhead |
| Interface Speed | 108 MHz SDR / 54 MHz DDR SPI - enables 13.5 MB/s peak read throughput in QPI mode |
| Endurance | 10¹⁴ read/write cycles - supports >27 years of continuous 100-Hz logging at full array depth |
| Data Retention | 151 years at +85°C - validated per JEDEC JESD22-A117, no refresh required |

| Active Current | 10 mA (typ) @ 108 MHz SDR - enables low-power burst logging in battery-backed systems |
Pinout & Package
8-pin small outline integrated circuit (SOIC) package, 150-mil width, RoHS-compliant, surface-mount compatible with standard reflow profiles.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar nonvolatile serial memory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CY15B102QSN-108SXIT | Wider VDD range (1.8–3.6 V); identical timing, density, and feature set | Preferred where system uses mixed 1.8 V / 3.3 V I/O rails or requires backward voltage compatibility | Select when board-level voltage margin exceeds ±5% of 1.8 V or when sharing design across multiple voltage platforms |
| FM25V02A-G | 2-Mbit F-RAM, 1.7–2.2 V, max 40 MHz SPI, no DDR or QPI support, no special sector | Limited to lower-bandwidth embedded control; lacks ECC/CRC and reflow-survivable sector | Choose only if cost sensitivity outweighs performance, reliability, and feature requirements |
Compared with CY15B102QSN-108SXIT, the CY15V102QSN-108SXIT trades voltage flexibility for tighter 1.8 V optimization and lower leakage; versus FM25V02A-G, it delivers 2.7× higher interface speed, full ECC/CRC, and production-ready reflow resilience-making it the sole choice for time-critical industrial firmware updates and safety-critical logging.

FAQ
Does CY15V102QSN-108SXIT require external hardware for write protection?
No. The device includes dual-layer write protection: hardware-based via the dedicated WP pin (active-low, level-sensitive), and software-configurable block protection using Status Register bits BP0–BP2. Both mechanisms can be used simultaneously for defense-in-depth security in certified systems.
Can CY15V102QSN-108SXIT operate in DDR mode with standard SPI controllers?
Yes, but only with controllers explicitly supporting SPI DDR protocol (e.g., NXP i.MX RT series, Microchip SAM E70, or Infineon XMC4000 with enhanced SPI peripheral). Standard SPI peripherals lacking DDR clock-edge sampling capability cannot drive the device in DDR mode.
What is the purpose of the 256-byte special sector F-RAM?
This sector is fabricated with enhanced thermal stability to survive ≥3 lead-free reflow cycles (JEDEC J-STD-020). It stores immutable data such as factory-calibrated sensor offsets, board serial numbers, or cryptographic keys-retaining validity even after PCB rework or module replacement.
How does on-die ECC interact with the memory array during normal operation?
ECC is transparent and automatic: every 8-byte write triggers on-die encoding; every 8-byte read performs decoding and correction before data output. Correctable errors do not interrupt operation; uncorrectable 2-bit errors set the ECCERR flag in SR2 and return corrupted data-requiring host-level retry or fallback logic.
