Product details
Overview
CY15V108QN-20LPXI 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 +85°C industrial temperature range, and 10¹⁵ read/write endurance. It serves as a non-volatile memory replacement for EEPROM/flash in data-logging systems requiring instant write, zero latency, and high reliability.
For engineers reviewing the CY15V108QN-20LPXI datasheet, CY15V108QN-20LPXI pinout, CY15V108QN-20LPXI application, or CY15V108QN-20LPXI equivalent, this page delivers verified technical context, SPI interface timing constraints, F-RAM-specific write protection architecture, special sector reflow survivability, and real-world trade-offs versus serial flash and EEPROM alternatives.
Technical Context
The CY15V108QN-20LPXI implements a true SPI slave interface compliant with Modes 0 (CPOL=0, CPHA=0) and 3 (CPOL=1, CPHA=1), supporting continuous read/write at bus speed without polling. Its internal control logic eliminates write delay overhead by completing each byte write before the next SPI cycle begins.
It integrates a non-volatile status register with WPEN bit, hardware write protect (WP pin), software block protection (1/4, 1/2, or full array), and a dedicated 256-byte special sector that retains data across three standard reflow cycles. The device also embeds manufacturer ID, product ID, unique device ID, and user-writable 8-byte serial number registers.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory density | 8 Mbit (1024K × 8), enabling direct byte-addressable non-volatile storage without erase blocks |
| SPI frequency | Up to 50 MHz - supports sub-200 ns per byte transfer, eliminating wait states during writes |
| Endurance | 10¹⁵ read/write cycles - sustains >27,000 writes/sec continuously for 15+ years without wear-out |
| Data retention | 151 years at +85°C - validated non-volatility without refresh or backup power |
| Supply voltage | 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 industrial control, metering, and automotive body electronics |
| Deep Power Down current | 0.9 µA typical - enables multi-year battery operation in always-on sensor nodes |
Pinout & Package
Package: 24-ball fine-pitch ball grid array (FBGA), 6 mm × 8 mm, 0.5 mm pitch, RoHS-compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| CS | Chip Select input | Active-low enable; places device in standby (7.5 µA) when HIGH; required falling edge before every opcode |
| SCK | Serial clock input | Synchronizes all I/O; rising edge latches SI, falling edge drives SO; supports 0–50 MHz with interruptible clock |
| SI | Serial input | Accepts opcodes, addresses, and data; sampled on SCK rising edge; must be driven to valid logic level for IDD compliance |
| SO | Serial output | Drives read data on SCK falling edge; tristated otherwise; supports single-pin SI/SO shared interface |
| WP | Write protect input | Hardware lock for status register when WPEN = 1; must tie to VDD if unused to prevent accidental protection |
| VDD | Power supply | 1.71–1.89 V nominal; powers core logic and F-RAM array; decoupling required per datasheet layout guidelines |
| VSS | Ground | System reference ground; must be low-impedance connection to minimize noise coupling into F-RAM cell sensing |
| DNU | Do Not Use | Internally unconnected; leave floating or tie to VDD - no electrical function or signal path |
| NC | No Connect | Die pad not bonded; electrically isolated; no routing or termination required |
Key Features
| Feature | Design Value |
|---|---|
| Instant non-volatile write | Zero write latency - data committed immediately after SPI byte transfer; no polling or timeout handling needed |
| Dedicated 256-byte special sector | Retains calibration data or firmware signatures across ≥3 reflow cycles - eliminates post-soldering programming |
| Multi-layer write protection | Hardware (WP pin) + software (WRDI, BP bits) + status register lock - prevents unintended writes in field-deployed units |
| Unique Device ID & serial number | Factory-programmed 64-bit UID + user-writable 8-byte serial register - enables secure device authentication and traceability |
| Low-voltage deep power down | 0.9 µA standby at 1.8 V - extends coin-cell life in maintenance-free IoT endpoints beyond 10 years |

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-20LPXI | Wider VDD range (1.8–3.6 V); higher active current (3.5 mA @ 50 MHz); same F-RAM core and pinout | Supports mixed-voltage systems (e.g., 3.3 V MCU with 1.8 V peripherals); less suitable for ultra-low-power 1.8 V-only designs | Select when system rail exceeds 1.89 V or when legacy 3.3 V compatibility is required |
| AT45DB081E-SSHN-B | 8-Mbit DataFlash with 512-byte pages; 100k endurance; 20 ms page write time; requires erase before write | Requires firmware-level wear leveling and write buffering; unsuitable for sub-millisecond write-critical logging | Choose only if cost sensitivity outweighs write latency and endurance requirements |
Compared with CY15B108QN-20LPXI, the CY15V108QN-20LPXI offers tighter voltage tolerance and lower quiescent current but sacrifices 3.3 V compatibility; versus AT45DB081E, it eliminates erase cycles and provides 10¹⁰× greater endurance, making it viable for deterministic real-time data capture.

FAQ
Is CY15V108QN-20LPXI pin-compatible with CY15B108QN-20LPXI?
Yes - both share identical 24-ball FBGA package, pin assignment, and SPI command set. The only hardware difference is the VDD operating range: CY15V108QN requires 1.71–1.89 V, while CY15B108QN supports 1.8–3.6 V. Swapping requires verifying system rail voltage and adjusting decoupling accordingly.
Does the special sector support write-protection independent of main array?
Yes - the 256-byte special sector has dedicated read/write instructions (RDSFR, WRSFR) and is protected separately via the SPRL bit in the status register. This allows calibration data to remain locked while permitting frequent updates to main array logging buffers.
Can the Unique Device ID be overwritten or disabled?
No - the 64-bit Unique Device ID is factory-programmed and read-only. It cannot be altered, erased, or disabled. Only the 8-byte user serial number register is writable via the WRSN instruction, and its contents persist across power cycles and reflows.
What SPI modes does CY15V108QN-20LPXI support, and how is mode selection handled?
The device supports SPI Mode 0 (CPOL=0, CPHA=0) and Mode 3 (CPOL=1, CPHA=1) exclusively. Mode selection is determined by the host controller's clock polarity and phase configuration - no internal register setting or command is required. Both modes are fully interoperable with standard SPI peripherals.
