Product details
Overview
CY15V108QN-20BFXIT from Infineon is an 8 Mb serial ferroelectric RAM (F-RAM) organized as 1024K × 8, operating on SPI interface at up to 40 MHz with 1.71–1.89 V supply, 151-year data retention, and 10¹⁵ write endurance-deployed in industrial data logging systems requiring deterministic non-volatile writes without polling.
For engineers reviewing the CY15V108QN-20BFXIT datasheet, CY15V108QN-20BFXIT pinout, CY15V108QN-20BFXIT application, or CY15V108QN-20BFXIT equivalent, this device delivers bus-speed non-volatile writes, hardware/software write protection, unique device ID, and a dedicated 256-byte reflow-survivable sector for critical configuration storage.
Technical Context
The CY15V108QN-20BFXIT implements a true SPI slave architecture supporting modes 0 and 3, with zero-latency write execution-data commits immediately after byte transfer without status polling. Its F-RAM core eliminates erase cycles and wear leveling, enabling deterministic timing for time-critical logging.
It integrates a non-volatile status register, 8-byte programmable serial number, manufacturer/product ID, and a dedicated 256-byte special sector that retains data through up to three standard reflow soldering cycles-critical for board-level traceability and factory programming.
Key Specifications
| Parameter | Value and Actual Design Meaning |

Pinout & Package
Package: 8-pin SOIC (Small Outline Integrated Circuit), RoHS-compliant, surface-mount, 150 mil body width.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| CS | Chip Select input | Active-low enable; places device in standby (3.5 µA) when HIGH; required falling edge before each opcode |
| SCK | Serial clock input | Synchronizes all I/O; rising edge latches SI, falling edge drives SO; supports 0–40 MHz with interruptible clock |
| SI | Serial input | Accepts opcodes, addresses, and write data; must be driven to valid logic level to meet IDD specs |
| SO | Serial output | Drives read data only during read operations; tristated otherwise; transitions on SCK falling edge |
| WP | Write protect input | Hardware lock for status register when WPEN = 1; must tie to VDD if unused |
| VSS | Ground | System reference ground; mandatory connection for stable operation and ESD integrity |
| VDD | Power supply | 1.71–1.89 V input; powers internal logic and F-RAM array; decoupling capacitor required |
| DNU | Do-not-use terminal | No internal connection; leave floating or tie to VDD-no electrical function |
Key Features
| Feature | Design Value |
|---|---|
| Instant non-volatile write | Zero write latency-no polling, no erase, no delay between bytes; next SPI transaction starts immediately |
| Dedicated reflow-survivable sector | 256-byte F-RAM block retains factory-programmed calibration data or MAC addresses across ≥3 reflow cycles |
| Hierarchical write protection | Combines hardware (WP pin), software (WRDI), and block-level (1/4, 1/2, full array) locking for secure firmware/data partitioning |
| Unique device identification | Read-only 64-bit Device ID + 64-bit Manufacturer ID + writable 8-byte serial number for system-level traceability |
| Ultra-low deep power-down | 0.90 µA typical current enables >10-year coin-cell operation in maintenance-free IoT endpoints |

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 |
|---|---|---|---|
| CY15B108QN-20BFXIT | Wider VDD range (1.8–3.6 V); same density, timing, and F-RAM architecture | Supports mixed-voltage systems (e.g., 3.3 V MCU with 1.8 V peripherals) | Select when design uses >1.89 V supply or requires backward compatibility with legacy 3.3 V interfaces |
| FM25V05-G | 512 Kb density; 1.7–2.2 V supply; max 40 MHz SPI; 10¹⁴ endurance; no special sector or serial number registers | Limited to lower-capacity, cost-sensitive applications without traceability needs | Choose only if 512 Kb suffices and unique ID/reflow survival are not required |
Compared with CY15B108QN-20BFXIT, the CY15V108QN-20BFXIT offers tighter voltage optimization for 1.8 V rails and lower deep-power-down current; versus FM25V05-G, it provides 16× more capacity, extended data retention, and production-grade traceability features essential for industrial certification.

FAQ
Is CY15V108QN-20BFXIT pin-compatible with CY15B108QN-20BFXIT?
Yes-both share identical 8-pin SOIC footprint, SPI pinout (CS, SCK, SI, SO, WP, VSS, VDD, DNU), and command set. The only functional difference is supply voltage range: CY15V108QN requires 1.71–1.89 V, while CY15B108QN operates from 1.8–3.6 V. Swapping requires verifying system rail compliance.
Does the 256-byte special sector support individual byte writes?
Yes-the dedicated special sector is fully byte-addressable and supports single-byte or burst writes identical to main array operations. Its key distinction is guaranteed retention through three standard Pb-free reflow cycles (JEDEC J-STD-020), making it ideal for factory-programmed identifiers or calibration data.
What SPI modes does CY15V108QN-20BFXIT support, and how is mode selection handled?
It supports SPI modes 0 (CPOL = 0, CPHA = 0) and 3 (CPOL = 1, CPHA = 1). Mode selection is fixed by host controller configuration-no internal register setting is required. The device detects clock polarity and phase behavior automatically upon CS assertion and operates correctly in either mode without firmware changes.
Can the unique device ID be overwritten or disabled?
No-the 64-bit Device ID and 64-bit Manufacturer ID are factory-laser-trimmed, one-time-programmed, and read-only. They cannot be altered, erased, or disabled. Only the 8-byte serial number register is user-writable and retains values across power cycles and reflows.
