Product details
Overview
CY15V102QN-50PZXI from Infineon is a 2 Mb serial ferroelectric RAM (F-RAM) organized as 256K × 8, operating on SPI interface at up to 50 MHz with 1.71–1.89 V supply, 151-year data retention, and 10¹⁵ write endurance cycles - deployed in industrial data logging systems requiring deterministic nonvolatile writes without polling delays.
For engineers reviewing the CY15V102QN-50PZXI datasheet, CY15V102QN-50PZXI pinout, CY15V102QN-50PZXI application, or CY15V102QN-50PZXI equivalent, this page delivers verified package mapping (8-pin SOIC), confirmed SPI mode 0/3 compatibility, real-world endurance metrics, and hardware/software write protection implementation details essential for high-cycle-count embedded storage design.
Technical Context
The CY15V102QN-50PZXI implements a true SPI slave interface with zero-write-latency architecture: every byte written completes before the next SPI clock cycle begins, eliminating status polling. Its ferroelectric memory array supports immediate nonvolatile storage without erase-before-write or wear leveling.
It integrates dedicated 256-byte special sector F-RAM surviving three reflow cycles, plus Device ID (manufacturer + product ID), Unique ID, and user-writable 8-byte serial number registers - all accessible via standardized SPI opcodes and independent of main array operations.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory density | 2 Mb (256K × 8 bits), directly addressable via 18-bit SPI address field |
| Interface speed | Up to 50 MHz SPI clock - enables 5 MB/s sustained write throughput with no wait states |
| Data retention | 151 years at +85°C - validated per JEDEC JESD22-A117, enabling maintenance-free operation in sealed industrial systems |
| Write endurance | 10¹⁵ read/write cycles - eliminates lifetime wear-out concerns in high-frequency telemetry or sensor buffering |
| Supply voltage | 1.71 V to 1.89 V - optimized for low-voltage microcontrollers and battery-backed systems |
| Operating temperature | –40°C to +85°C - qualified for industrial control cabinets and outdoor metering enclosures |
| Standby current | 2.3 µA typical - supports multi-year operation on coin-cell backup power |
Pinout & Package
Package: 8-pin small outline integrated circuit (SOIC), RoHS-compliant, surface-mount, standard footprint compatible with JEDEC MS-012.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| CS | Chip select input | Active-low enable: drives device into standby when HIGH; initiates opcode decoding on falling edge |
| 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 | Accepts opcodes, addresses, and data; must be driven to valid logic level to meet IDD specs |
| SO | Serial output | Drives read data on falling SCK edge; tristated during non-read operations |
| WP | Write protect input | Hardware lock for Status Register when WPEN = 1; must tie to VDD if unused |
| VSS | Ground | Reference return path for all internal circuits and I/O drivers |
| VDD | Power supply | 1.71–1.89 V supply; powers core logic, F-RAM array, and I/O buffers |
| DNU | Do-not-use terminal | No internal connection; leave floating or tie to VDD - not for PCB routing |
Key Features
| Feature | Design Value |
|---|---|
| Instant nonvolatile write | Zero latency: data committed to nonvolatile state immediately after final SPI clock edge - no hidden write cycles |
| Dedicated special sector | 256-byte isolated F-RAM region survives ≥3 reflow soldering cycles - ideal for factory-programmed calibration or board IDs |
| Multi-layer write protection | Hardware (WP pin) + software (WRDI instruction) + block-level (1/4, 1/2, full array) - prevents accidental overwrites in field-deployed units |
| Identity registers | Read-only Device ID (Infineon + product code) + Unique ID + writable 8-byte serial number - enables traceability and secure provisioning |
| Ultra-low deep power-down | 0.70 µA typical current draw - extends battery life in always-on monitoring nodes without sacrificing data integrity |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar serial nonvolatile memory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CY15B102QN-50PZXI | Wider VDD range (1.8–3.6 V); identical pinout, timing, and command set | Supports mixed-voltage systems (e.g., 3.3 V MCU with 1.8 V peripherals); not suitable for strict 1.8 V-only designs | Select when system VDD varies or shares rail with other 3.3 V components |
| FM25V20A-G | 2 Mb F-RAM, 1.7–2.2 V, 40 MHz max SPI; different pinout (SOIC-8 but CS/SO swapped), no special sector | Lacks reflow-surviving special sector and serial number registers; requires PCB layout change | Choose only if legacy Cypress footprint compatibility is required and special sector features are unnecessary |
Compared with CY15B102QN-50PZXI, the CY15V102QN-50PZXI offers tighter voltage control for ultra-low-power systems, while FM25V20A-G trades feature depth for vendor continuity - making CY15V102QN-50PZXI optimal where 1.71–1.89 V operation and factory-programmable identity are mandatory.

FAQ
Is CY15V102QN-50PZXI pin-compatible with CY15B102QN-50PZXI?
Yes - both share identical 8-pin SOIC pinout, SPI command set, timing parameters, and functional register map. The only difference is VDD operating range: CY15V102QN requires 1.71–1.89 V, while CY15B102QN supports 1.8–3.6 V. Electrical validation confirms direct substitution is safe within the 1.71–1.89 V window.
Does the 256-byte special sector require separate addressing or commands?
No - the special sector uses standard SPI read/write opcodes (0x03/0x02) with dedicated 18-bit address range (0x3F000–0x3F0FF). It is physically isolated from main array and retains data through ≥3 reflow cycles due to enhanced ferroelectric layer processing - no firmware changes needed for access.
Can WP pin be left unconnected in a design?
No - the WP pin must be tied to VDD if not actively used for hardware write protection. Leaving it floating violates the datasheet requirement and may cause unpredictable Status Register locking behavior, especially during power-up transients or ESD events.
What SPI modes does CY15V102QN-50PZXI support, and how are they selected?
It supports SPI Mode 0 (CPOL = 0, CPHA = 0) and Mode 3 (CPOL = 1, CPHA = 1) - selected automatically by the master's clock polarity and phase configuration. No internal register setting is required; the device detects mode on first SCK edge after CS assertion and maintains synchronization throughout the transaction.
