Product details
Overview
CY15V104QSN-108BFXI from Infineon is a 4-Mbit ferroelectric RAM (F-RAM) organized as 512K × 8, supporting quad SPI (QPI) up to 108 MHz SDR and 54 MHz DDR, with 100 trillion (10¹⁴) read/write cycles, 151-year data retention, and 1.71–1.89 V operation for industrial applications including real-time data logging in PLCs and sensor edge nodes.
For engineers reviewing the CY15V104QSN-108BFXI datasheet, CY15V104QSN-108BFXI pinout, CY15V104QSN-108BFXI application, or CY15V104QSN-108BFXI equivalent, key selection criteria include non-volatile write speed at bus rate, on-die ECC/CRC integrity, hardware/software write protection, and compatibility with low-voltage 1.8 V systems requiring high endurance and zero write latency.
Technical Context
The CY15V104QSN-108BFXI implements a true RAM-like interface over quad SPI, enabling execute-in-place (XIP) reads and immediate byte-level writes without polling or erase cycles. Its ferroelectric memory array eliminates wear leveling and page programming overhead inherent in flash.
It supports SPI modes 0 and 3 for SDR transfers and mode 0 only for DDR, with dedicated configuration registers (CR1–CR5) controlling latency, QPI/DPI enable, output impedance, and deep-power-down behavior. The device integrates dual status registers (SR1/SR2) for WEL, BP, CRC control, and ECC reporting.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory density | 4 Mbit (512K × 8), directly addressable without sector erase - enables byte-write persistence in cyclic buffer applications. |
| Interface speed | 108 MHz SDR / 54 MHz DDR quad SPI - sustains 432 MB/s effective throughput in QPI SDR mode for burst streaming. |
| Endurance | 10¹⁴ read/write cycles - supports >27 years of continuous 100 Hz logging at full density without degradation. |
| Data retention | 151 years at +85°C - guarantees archival integrity in unpowered industrial deployments without refresh. |
| Voltage range | 1.71 V to 1.89 V - matches LPDDR2/LPDDR3 I/O domains and avoids level-shifting in 1.8 V microcontroller systems. |
| ECC capability | Detects and corrects 1-bit errors per 8-byte unit; reports 2-bit errors via status register - ensures deterministic fault handling in safety-critical firmware storage. |
| Power consumption | 10 mA active (108 MHz SDR), 110 µA standby, 0.8 µA deep power-down - enables battery-backed operation for >10 years in energy-constrained edge nodes. |
Pinout & Package
Supplied in an 8-pin SOIC package (3.9 mm × 4.9 mm, 1.27 mm pitch), compatible with standard reflow profiles and legacy PCB footprints. Pin functions are validated per Infineon datasheet 002-18293 Rev. *O.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| CS | Chip Select | Active-low enable for SPI command decoding; must be held stable during instruction and data phases. |
| SCK | Serial Clock | Master-generated clock driving all SPI transfers; supports up to 108 MHz SDR timing with tight setup/hold margins. |
| SI (I/O0) | Serial Input / Quad I/O Line 0 | Primary data input in single/dual mode; functions as I/O0 in QPI for bidirectional command/address/data transfer. |
| SO (I/O1) | Serial Output / Quad I/O Line 1 | Primary data output in single mode; serves as I/O1 in QPI for parallel data lane operation. |
| WP (I/O2) | Write Protect Input / Quad I/O Line 2 | Hardware-enabled sector lock; when asserted low, blocks write commands regardless of software BP settings. |
| RESET (I/O3) | Reset Input / Quad I/O Line 3 | Asynchronous reset that clears internal state and forces exit from deep power-down; configurable as I/O3 in QPI. |
Key Features
| Feature | Design Value |
|---|---|
| Dedicated 256-byte special sector | Persists through three standard reflow cycles - enables secure storage of calibration data or board identity in manufacturing test fixtures. |
| On-die ECC + CRC | Corrects 1-bit errors and flags 2-bit errors per 8-byte unit; CRC validates entire memory array integrity - reduces host-side error-handling firmware overhead. |
| Instant non-volatile write | No write latency or polling required - enables deterministic 100 ns worst-case write completion, critical for time-stamped event capture. |
| Extended electronic signatures | Includes factory-programmed unique ID, user-programmable serial number, and read-only device ID - supports secure boot chain binding and field asset tracking. |
| Low-voltage 1.8 V operation | Guaranteed functionality from 1.71 V - allows direct interfacing with 1.8 V MCUs (e.g., STM32L4+, RP2040) without voltage translation. |

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 |
|---|---|---|---|
| CY15B104QSN-108BFXI | Wider VDD range (1.8–3.6 V); identical pinout, timing, and feature set. | Supports mixed-voltage systems (e.g., 3.3 V MCU with 1.8 V peripherals); not suitable for strict 1.8 V-only designs. | Select when system rail flexibility outweighs need for lowest possible VDD; shares same footprint and firmware. |
| FM25V20A-G | 2-Mbit density, 40 MHz max SPI, no DDR/QPI, no on-die ECC/CRC, 1.7–2.2 V. | Limited to lower-bandwidth, lower-integrity applications; lacks XIP and advanced data protection. | Choose only for cost-sensitive, low-endurance use cases where 10¹² cycles and basic CRC suffice. |
Compared with CY15B104QSN-108BFXI, the CY15V104QSN-108BFXI offers tighter voltage tolerance ideal for 1.8 V SoCs but sacrifices rail flexibility; versus FM25V20A-G, it delivers 2× density, 2.7× speed, full ECC/CRC, and 100× endurance - justifying premium use in mission-critical edge storage.

FAQ
Does CY15V104QSN-108BFXI require external high-voltage programming or erase pulses?
No. Unlike flash or EEPROM, this F-RAM performs true random-access writes at bus speed using standard 1.8 V I/O levels. No erase cycles, no program voltage boosters, and no write latency are required - each byte is committed immediately upon successful SPI transfer, enabling deterministic real-time data capture without polling.
Can the dedicated 256-byte special sector survive lead-free reflow soldering?
Yes. The special sector is qualified to retain data through up to three standard JEDEC J-STD-020D reflow cycles (peak 260°C). This allows permanent storage of factory-calibrated sensor offsets, board serial numbers, or cryptographic keys that must persist from manufacturing through field deployment without reprogramming.
How does on-die ECC interact with host firmware during normal operation?
ECC operates transparently in hardware: 1-bit errors are corrected automatically on read, and the ECC status register (bit 0 of SR2) flags uncorrectable 2-bit errors. Host firmware can poll this bit after critical reads or configure interrupts via external GPIO monitoring - no software ECC calculation or buffer management is needed.
Is quad SPI (QPI) mode enabled by default after power-up?
No. QPI mode must be explicitly enabled by setting the QPI bit (CR2[6]) via the WRAR command (71h). Power-on defaults to standard single-I/O SPI mode (mode 0), ensuring backward compatibility with legacy controllers. Switching to QPI requires issuing the proper configuration sequence and verifying CR2 readback.
