Product details

Overview

CY15V108QSN-108BKXQ from Infineon is an 8-Mbit serial ferroelectric RAM (F-RAM) organized as 1024K × 8, operating at up to 50 MHz SPI clock speed with 1.71–1.89 V supply voltage and extended industrial temperature range (–40°C to +105°C). It delivers instant non-volatile writes, 10¹⁴ read/write endurance, and 151-year data retention-enabling high-frequency logging in battery-powered industrial sensors and real-time control systems.

For engineers reviewing the CY15V108QSN-108BKXQ datasheet, CY15V108QSN-108BKXQ pinout, CY15V108QSN-108BKXQ application, or CY15V108QSN-108BKXQ equivalent, key selection criteria include SPI Mode 0/3 compatibility, hardware/software write protection, dedicated 256-byte reflow-survivable sector, ultra-low deep power-down current (1.10 µA), and FBGA-24 package integration for space-constrained embedded designs.

Technical Context

The CY15V108QSN-108BKXQ implements a synchronous SPI slave interface with zero-write-latency architecture: data commits immediately upon byte transfer without polling, eliminating flash/EEPROM erase delays. Its internal logic includes a non-volatile status register, device ID/serial number registers, and a dedicated 256-byte special sector F-RAM hardened for three reflow cycles.

It supports dual SPI modes (0 and 3), uses rising-edge input sampling and falling-edge output driving on SCK, and integrates hardware write protection via active-low WP pin-enabled only when WPEN bit is set in the status register. Power management includes Hibernate (0.1 µA), Deep Power-down (1.10 µA), and standby (9 µA) states.

Key Specifications

Parameter	Value and Actual Design Meaning
Memory Density	8 Mbit (1024K × 8), enabling storage of 1 MB of configuration or telemetry data without external address latching.
SPI Clock Frequency	Up to 50 MHz, supporting 5 MB/s sustained write throughput-critical for burst data capture in PLC I/O modules.
Write Endurance	10¹⁴ cycles, permitting continuous logging every 100 ms for >31 years without wear-out failure.
Data Retention	151 years at +105°C, ensuring firmware parameter integrity across full product lifecycle in automotive ECUs.
Supply Voltage	1.71 V to 1.89 V, matching LP DDR3/LPDDR4 core rail requirements and eliminating level-shifting in modern SoC subsystems.
Operating Temperature	–40°C to +105°C (extended industrial), qualified for under-hood automotive and factory-floor automation deployments.
Deep Power-down Current	1.10 µA (typ), extending battery life to >10 years in wireless sensor nodes powered by CR2032 cells.

Pinout & Package

Package: 24-ball fine-pitch ball grid array (FBGA), 4.0 mm × 3.0 mm × 0.75 mm body, 0.5 mm ball pitch, RoHS-compliant.

Pin/Terminal	Circuit Role	Design Meaning
CS	Chip Select Input	Active-low enable: drives device into standby and tristates SO when HIGH; must fall before each opcode to initiate SPI transaction.
SCK	Serial Clock Input	Synchronizes all I/O; inputs sampled on rising edge, outputs driven on falling edge; supports 0–50 MHz with interruptible clock.
SI	Serial Input	Accepts opcodes, addresses, and write data; must be held valid during operation to meet IDD specs; may share trace with SO in single-wire mode.
SO	Serial Output	Drives read data only during active read commands; high-impedance otherwise; transitions aligned to SCK falling edge.
WP	Write Protect Input	Hardware lock for status register writes when WPEN = 1; must tie to VDD if unused to prevent accidental protection activation.
VDD	Power Supply	1.71–1.89 V core supply; decoupling capacitor required within 10 mm for stable 50 MHz operation.
VSS	Ground	Reference return path for all digital and analog circuitry; requires low-inductance connection to system ground plane.
DNU	Do Not Use	Ball must remain unconnected or tied to VDD; no internal connection-floating acceptable per datasheet guidance.
NC	No Connect	Die pad not bonded; electrically isolated-no PCB routing or soldering required.

Key Features

Feature	Design Value
Instant Non-Volatile Write	Zero latency commit: data written at bus speed with no erase cycle or polling-eliminates risk of data loss during power fail in metering applications.
Dedicated Reflow-Survivable Sector	256-byte F-RAM sector retains content through three standard Pb-free reflow cycles (260°C peak), enabling secure bootloader storage on production-line-programmed boards.
Multi-Layer Write Protection	Hardware (WP pin), software (WRDI instruction), and block-level (1/4, 1/2, full array) protection-prevents accidental firmware overwrite in field-upgradable medical devices.
Unique Device Identity	Factory-programmed 64-bit unique ID + 8-byte user-writable serial number register-supports secure device authentication and board-level traceability in IIoT gateways.
Ultra-Low Hibernate Current	0.1 µA typical consumption in hibernate mode-extends shelf life and enables wake-on-event functionality in always-on edge nodes.

Equivalent & Alternatives

The following parts are listed as comparable options for similar serial non-volatile memory applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
CY15B108QSN-108BKXQ	Wider VDD range (1.8–3.6 V); identical density, timing, and package; no voltage-level shifters needed in 3.3 V systems.	Preferred for mixed-voltage designs where host MCU runs at 3.3 V but CY15V108QSN requires level translation.	Select when system VDD ≥ 1.8 V and design flexibility for future voltage scaling is required.
FM25V05-G	512 Kbit density (half capacity); same 1.7–1.9 V range and 50 MHz SPI; lacks dedicated reflow-survivable sector and unique ID registers.	Suitable for cost-sensitive, lower-data-volume applications like simple sensor nodes or legacy industrial controllers.	Choose only if 4 Mb is sufficient and advanced identity/security features are unnecessary.

Compared with CY15B108QSN-108BKXQ, the CY15V108QSN-108BKXQ offers tighter voltage tolerance ideal for battery-fed 1.8 V rails, while FM25V05-G trades capacity and feature depth for lower unit cost-making it viable only where 4 Mb suffices and reflow-hardened sectors aren't mandated.

FAQ

Is CY15V108QSN-108BKXQ pin-compatible with standard SPI serial flash or EEPROM devices?

Yes-it uses the industry-standard 8-pin SPI footprint (CS, SCK, SI, SO, WP, HOLD, VDD, VSS) mapped to a 24-ball FBGA package. Pin functions align with JEDEC MS-026, enabling direct PCB layout reuse when replacing flash/EEPROM in existing designs, provided WP and HOLD pins are correctly configured per F-RAM's protection scheme.

Does CY15V108QSN-108BKXQ require external high-voltage programming circuitry?

No. Unlike EEPROM or flash, it performs writes at standard VDD (1.71–1.89 V) with no charge pump or elevated voltage generation. All operations-including status register modification and sector protection-execute using only the core supply, simplifying power design and eliminating HV-related EMI and reliability risks.

Can the dedicated 256-byte special sector survive lead-free rework?

Yes. The special sector is qualified for three full Pb-free reflow cycles (peak 260°C, 60 sec max), verified per J-STD-020. This allows safe in-system programming of bootloader code or calibration data post-assembly-even after board-level rework-without data corruption.

What SPI modes does CY15V108QSN-108BKXQ support, and how is mode selection handled?

It supports SPI Modes 0 (CPOL = 0, CPHA = 0) and 3 (CPOL = 1, CPHA = 1) only. Mode selection is fixed by host controller configuration-no internal register or command sets the mode. The device automatically adapts to the master's clock polarity and phase settings, requiring no initialization sequence beyond standard CS/SCK timing compliance.
