Product details
Overview
CY15V104QSN-108SXIT from Infineon is a 4 Mb serial 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 for industrial embedded logging and real-time data buffering.
For engineers reviewing the CY15V104QSN-108SXIT datasheet, CY15V104QSN-108SXIT pinout, CY15V104QSN-108SXIT application, or CY15V104QSN-108SXIT equivalent, this device delivers instant non-volatile writes, on-die ECC and CRC for integrity-critical telemetry, and hardware/software write protection for secure firmware parameter storage in harsh environments.
Technical Context
The CY15V104QSN-108SXIT implements a true RAM-like interface over quad SPI, eliminating write latency and polling-data commits immediately upon byte transfer. Its ferroelectric memory array enables byte-level random writes without erase cycles, unlike flash-based alternatives.
It integrates dual status registers (SR1/SR2), five configuration registers (CR1–CR5), and dedicated control logic for QPI/SDR/DDR mode selection, WP pin assertion, reset handling via IO3, and deep power-down activation. ECC operates per 8-byte unit, detecting/correcting 1-bit errors and flagging 2-bit errors.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Density | 4 Mbit (512K × 8), enabling compact firmware parameter tables or sensor history buffers without external address latching. |
| Interface Speed | 108 MHz SDR / 54 MHz DDR quad SPI, delivering up to 432 MB/s effective throughput for high-frequency data capture. |
| Endurance | 10¹⁴ read/write cycles - supports continuous logging at 1 kHz for >3,170 years without wear-out concern. |
| Data Retention | 151 years at +85°C, ensuring unpowered data survival across product lifecycles in industrial automation systems. |
| Voltage Range | 1.71–1.89 V supply, matching low-voltage SoC I/O domains and reducing level-shifting complexity. |
| Power Consumption | 10 mA active (108 MHz SDR), 110 µA standby, 0.8 µA deep power-down - suitable for battery-backed edge nodes. |
| Error Handling | On-die ECC corrects 1-bit errors per 8-byte unit; CRC validates full-array integrity during boot or diagnostics. |
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/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 driving all SDR/DDR transfers; max 108 MHz for SDR, 54 MHz for DDR mode. |
| SI (I/O0) | Serial Input / Quad I/O Line 0 | Input for commands, addresses, and data in single/dual mode; functions as I/O0 in quad mode. |
| SO (I/O1) | Serial Output / Quad I/O Line 1 | Output for read data and status; serves as I/O1 in quad mode with bidirectional capability. |
| WP (I/O2) | Write Protect Input | Hardware lock disabling all write operations when held low; overrides software block protection. |
| RESET (I/O3) | Reset Input / Configuration Control | Pull-low resets internal state; also controls IO3 reset behavior via CR2[5] configuration bit. |
| VDD | Power Supply | 1.71–1.89 V core supply; decoupling required within 5 mm of pin per datasheet layout guidelines. |
| VSS | Ground | Reference return path for all digital and analog circuitry; tied to PCB ground plane with low-inductance connection. |
Key Features
| Feature | Design Value |
|---|---|
| Instant Non-Volatile Write | Zero-latency commit: data written to array immediately after SPI transfer completes-no wait states or polling needed. |
| Dedicated 256-Byte Special Sector | Retains content through three standard reflow cycles, enabling factory-programmed calibration data or security keys. |
| Quad SPI + DDR Support | Enables 4× bandwidth vs. standard SPI; DDR mode doubles throughput without increasing clock frequency. |
| Unique ID & Serial Number | Factory-programmed read-only identifiers support board-level traceability, secure boot binding, and counterfeit detection. |
| Hibernate Mode Current | 0.1 µA draw allows multi-year battery operation in always-on monitoring devices with infrequent wake-ups. |

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-108SXIT | Same F-RAM core and pinout, but wider VDD range (1.8–3.6 V); no 1.71–1.89 V optimization. | Preferred for mixed-voltage systems where 3.3 V I/O coexists with 1.8 V logic rails. | Select when system VDD exceeds 1.89 V or requires backward compatibility with legacy 3.3 V SPI masters. |
| FM25V04-G | 4 Mb F-RAM with SPI (not quad), max 40 MHz SDR; lacks DDR, QPI, ECC, and unique ID features. | Suitable for cost-sensitive, lower-bandwidth applications where 108 MHz and advanced integrity features are unnecessary. | Choose only if design does not require >40 MHz throughput, ECC, or cryptographic traceability features. |
Compared with CY15B104QSN-108SXIT, the CY15V104QSN-108SXIT offers tighter voltage tolerance for ultra-low-power SoCs, while FM25V04-G trades performance and reliability features for simpler integration and lower BOM cost.

FAQ
Does CY15V104QSN-108SXIT support execute-in-place (XIP) operation?
Yes, the device supports XIP for memory reads and writes, allowing direct code execution from F-RAM without copying to SRAM. This reduces boot time and simplifies memory mapping in resource-constrained microcontrollers, provided the host SPI controller supports memory-mapped access mode and appropriate timing constraints.
How is the 256-byte special sector protected during PCB reflow?
The special sector retains data through up to three standard JEDEC J-STD-020D reflow cycles (peak 260°C) due to its dedicated ferroelectric cell structure and optimized programming algorithm. It is write-protected by default after factory programming and requires explicit unlock via WRAR command before modification.
What happens when a 2-bit error occurs in an 8-byte ECC unit?
The on-die ECC logic detects but does not correct 2-bit errors; instead, it sets the ECC error flag (ECCERR) in Status Register 2. Host firmware must read SR2 to identify affected addresses and initiate recovery-such as reloading from backup or triggering a system alert-based on application-criticality policies.
Can the unique ID and serial number be rewritten after factory programming?
No-the unique ID is laser-trimmed during wafer test and permanently fixed; the user-programmable serial number is stored in one-time-programmable (OTP) registers and cannot be altered once written. Both fields are read-only thereafter, ensuring immutable device identity for security and traceability use cases.
