Product details
Overview
CY15V104QSN-108SXI 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 endurance, 151-year data retention, and 1.71–1.89 V operation - deployed in industrial data logging systems requiring deterministic non-volatile writes without write latency.
For engineers reviewing the CY15V104QSN-108SXI datasheet, CY15V104QSN-108SXI pinout, CY15V104QSN-108SXI application, or CY15V104QSN-108SXI equivalent, key selection criteria include instant-write capability, ECC-corrected 8-byte units, hardware WP pin support, QPI/DDR interface compatibility, and SOIC-8 industrial temperature range (–40°C to +85°C).
Technical Context
The CY15V104QSN-108SXI implements a true RAM-like interface over quad SPI, eliminating erase-before-write and polling delays inherent in flash. Its ferroelectric memory array enables byte-level random writes at bus speed, with no block management overhead.
It integrates dual status registers (SR1/SR2), four configuration registers (CR1–CR5), on-die ECC for 1-bit correction per 8-byte unit, CRC for array integrity verification, and dedicated 256-byte special sector surviving three reflow cycles - all accessible via standardized SPI opcodes including WREN, RDSR1, RDCR2, and WRAR.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory density | 4 Mbit (512K × 8), enabling compact firmware/data storage without external address latching |
| Interface speed | 108 MHz SDR / 54 MHz DDR quad SPI - delivers up to 432 MB/s effective throughput in QPI mode |
| Endurance | 10¹⁴ read/write cycles - supports >27,000 writes/sec continuously for 10+ years in high-frequency telemetry |
| Data retention | 151 years at +85°C - eliminates periodic refresh or backup power requirements in sealed industrial enclosures |
| Voltage range | 1.71 V to 1.89 V - optimized for low-power 1.8 V system rails with tight regulation tolerance |
| Operating temp | –40°C to +85°C - qualified for uncontrolled industrial environments without derating |
| ECC capability | Detects and corrects 1-bit error per 8-byte unit; reports 2-bit errors via status register - ensures deterministic fault handling in safety-critical logging |
Pinout & Package
Package: 8-pin SOIC (Small Outline Integrated Circuit), surface-mount, RoHS-compliant, industrial-grade moisture sensitivity level (MSL3).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| CS | Chip Select | Active-low enable for SPI command decoding; must be asserted before SCK edge to initiate transaction |
| SCK | Serial Clock | Master-generated clock; supports SDR (108 MHz) and DDR (54 MHz) modes with configurable phase/polarity |
| 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 quad data transfer |
| SO (I/O1) | Serial Output / Quad I/O Line 1 | Primary data output in single mode; functions as I/O1 in QPI for full-duplex quad reads |
| WP (I/O2) | Write Protect Input | Hardware-enabled sector protection; tied low to disable writes to protected memory blocks |
| RESET (I/O3) | Reset Input / Quad I/O Line 3 | Active-low reset signal; also serves as I/O3 in QPI mode; configurable via CR2[5] (IO3R) |
| VDD | Power Supply | 1.71–1.89 V supply; decoupling required within 5 mm of pin for stable 108 MHz operation |
| VSS | Ground | Reference return path for all I/O and core logic; separate analog/digital ground not required |
Key Features
| Feature | Design Value |
|---|---|
| Instant non-volatile write | Zero-latency byte writes - no wait states or polling; next SPI cycle starts immediately after data transfer |
| Dedicated 256-byte special sector | Retains calibration data or security keys across ≥3 lead-free reflow cycles - usable for factory-programmed device identity |
| On-die ECC & CRC | ECC corrects 1-bit errors per 8-byte unit; CRC validates full-array integrity - reduces host-side error-handling firmware complexity |
| Quad SPI + DDR support | Enables 4× bandwidth vs standard SPI; DDR mode doubles throughput without increasing clock frequency - critical for burst telemetry capture |
| User-programmable serial number | Read-only 64-bit unique ID plus 32-bit user-writable serial number - supports board-level traceability and secure boot binding |

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-108SXI | 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 F-RAM rail); not suitable for strict 1.8 V-only designs | Select when system voltage margin exceeds ±5% or when sharing supply with 3.3 V peripherals |
| FM25V04-G | 4 Mb F-RAM, SPI SDR only (max 40 MHz); no DDR/QPI; no on-die ECC or CRC | Lacks high-speed burst capability and embedded data integrity features; requires external error handling | Choose only if cost sensitivity outweighs throughput and reliability requirements in low-bandwidth logging |
Compared with CY15B104QSN-108SXI, the CY15V104QSN-108SXI offers tighter voltage tolerance for 1.8 V systems but sacrifices multi-rail flexibility; versus FM25V04-G, it delivers 2.7× faster interface speed and integrated ECC/CRC - directly reducing host CPU load and qualification risk in medical/industrial deployments.

FAQ
Does CY15V104QSN-108SXI support execute-in-place (XIP) functionality?
Yes, the device supports XIP for memory read operations, allowing direct code execution from F-RAM without copying to SRAM. This reduces boot time and simplifies memory mapping in resource-constrained microcontrollers. XIP is enabled via configuration register settings and operates across all supported SPI modes, including QPI DDR, with no additional latency beyond standard read access timing.
What is the purpose of the dedicated 256-byte special sector?
The dedicated 256-byte special sector retains data through up to three standard lead-free reflow cycles (JEDEC J-STD-020), making it ideal for factory-programmed calibration constants, cryptographic keys, or device-specific identifiers. It is accessed using unique opcodes (e.g., RDSFR, WRSFR) and is write-protected independently from main array sectors via status register bits.
How does the ECC implementation differ from typical Hamming-code-based schemes?
This device implements on-die ECC that detects and corrects exactly one bit error per 8-byte data unit, with explicit reporting of uncorrectable 2-bit errors in the ECC status register. Unlike software-managed Hamming codes, this hardware ECC operates transparently during read cycles and requires no host intervention - reducing firmware overhead and ensuring deterministic response in safety-certified systems.
Can the RESET pin be repurposed as a general-purpose I/O in quad SPI mode?
Yes, when QPI mode is enabled (CR2[6] = 1) and IO3 reset is disabled (CR2[5] = 0), the RESET pin functions as I/O3 for full quad data transfer. This reconfiguration is persistent across power cycles and does not affect the device's ability to enter deep power-down or hibernate modes - both remain controllable via command sequences.
