Product details
Overview
CY15V108QN-50BKXQT from Infineon is an 8-Mbit serial ferroelectric RAM (F-RAM) organized as 1024K × 8, operating at up to 50 MHz SPI clock, with 1.71–1.89 V supply, -40°C to +105°C extended industrial temperature range, and 100 trillion (10¹⁴) read/write endurance. It serves as a non-volatile memory replacement for serial EEPROM/flash in data logging, industrial control, and metering systems requiring instant write, zero latency, and high reliability.
For engineers reviewing the CY15V108QN-50BKXQT datasheet, CY15V108QN-50BKXQT pinout, CY15V108QN-50BKXQT application, or CY15V108QN-50BKXQT equivalent, this page delivers verified electrical parameters, validated SPI interface behavior, confirmed FBGA-24 package mapping, real-world endurance and retention metrics, and direct drop-in context versus legacy non-volatile memories.
Technical Context
The CY15V108QN-50BKXQT implements a true SPI slave interface supporting Modes 0 and 3, with data latched on SCK rising edge and output driven on falling edge - enabling deterministic, bus-speed writes without polling. Its F-RAM core eliminates erase cycles and write delays inherent in flash/EEPROM, delivering immediate byte-level non-volatile storage.
It integrates hardware write protection via active-low WP pin, software-controlled status register (WRDI, BP bits), and a dedicated 256-byte special sector that survives three reflow cycles. The device includes manufacturer ID, product ID, unique device ID, and user-writable 8-byte serial number registers - all accessible via standard SPI opcodes.

Pinout & Package
Package: 24-ball fine-pitch ball grid array (FBGA), 4.0 mm × 3.0 mm, 0.5 mm pitch, RoHS-compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| CS | Chip Select input | Active-low enable: asserts SPI interface and powers internal logic; HIGH places device in standby (9 µA) |
| SCK | Serial clock input | Synchronizes all I/O; rising edge latches SI, falling edge drives SO; supports 0–50 MHz with interrupt tolerance |
| SI | Serial input | Receives opcodes, addresses, and write data; must be driven to valid logic level to meet IDD specs |
| SO | Serial output | Drives read data during read operations; high-impedance otherwise; transitions on SCK falling edge |
| WP | Write protect input | Hardware lock for Status Register when WPEN = 1; must tie to VDD if unused |
| VDD | Power supply | 1.71–1.89 V core supply; decoupling required per datasheet layout guidelines |

| NC | No Connect | Die pad not bonded; electrically inactive; no PCB trace or solder mask opening needed |
Key Features
| Feature | Design Value |
|---|---|
| Instant non-volatile write | Writes complete at bus speed - no delay, no polling, no erase - enabling deterministic real-time logging |
| Dedicated 256-byte special sector | Retains calibration data or firmware signatures across ≥3 reflow cycles - critical for field-programmable modules |
| Unique device ID + serial number | Enables secure device authentication and board-level traceability without external EEPROM or OTP |

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 |
|---|---|---|---|
| CY15B108QN-50BKXQT | Wider VDD range (1.8–3.6 V); identical timing, density, and endurance; same FBGA-24 package | Preferred where system uses mixed 1.8/3.3 V rails or legacy 3.3 V design reuse is required | Select CY15B108QN only if 3.3 V compatibility is mandatory; CY15V108QN offers lower quiescent current at 1.8 V |
| AT45DB081E-SHN-T | 8-Mbit DataFlash; requires erase-before-write; 100k endurance; 20-year retention; SOIC-8 package | Acceptable only in cost-sensitive, low-write-frequency applications with relaxed reliability requirements | Not recommended for high-write or mission-critical use; lacks instant write, unique ID, and extended temp rating |
Compared with CY15B108QN-50BKXQT, the CY15V108QN-50BKXQT provides tighter voltage regulation (1.71–1.89 V), lower deep-power-down current (1.10 µA vs 2.5 µA), and optimized 1.8 V system integration - while AT45DB081E-SHN-T introduces erase latency, limited endurance, and package incompatibility, making it unsuitable for demanding industrial logging.

FAQ
Is CY15V108QN-50BKXQT pin-compatible with CY15B108QN-50BKXQT?
Yes - both share identical 24-ball FBGA package, pinout, and SPI interface timing. The only functional difference is supply voltage range: CY15V108QN operates strictly at 1.71–1.89 V, while CY15B108QN supports 1.8–3.6 V. No PCB redesign is needed for voltage-limited 1.8 V systems.
Does CY15V108QN-50BKXQT require external hardware for write protection?
No - it integrates dual-layer write protection: hardware via the active-low WP pin (when WPEN bit is set), and software via WRDI instruction and BP bits in the status register. WP pin must be tied to VDD if unused; no external components are required for basic protection.
Can the unique device ID and serial number be rewritten by the host system?
The manufacturer ID and product ID are factory-programmed and read-only. The unique device ID is also factory-programmed and immutable. However, the 8-byte serial number register is user-writable via SPI command, allowing board-level identification and field programming during manufacturing or service.
What is the maximum junction temperature during reflow for the 24-ball FBGA package?
The CY15V108QN-50BKXQT is qualified for JEDEC J-STD-020D-compliant lead-free reflow profiles. Peak package temperature is 260°C for ≤30 seconds, with the dedicated 256-byte special sector guaranteed to retain data across three such reflow cycles - critical for module-level rework and second-source assembly.
