Product details
Overview
CY15V102QN-50SXE from Infineon is an automotive-grade 2 Mb ferroelectric RAM (F-RAM) organized as 256K × 8, supporting SPI up to 50 MHz with 1.71–1.89 V supply, –40°C to +125°C operation, and AEC-Q100 Grade 1 qualification. It delivers instant non-volatile writes, 10¹³ endurance cycles, and 121-year data retention for critical automotive data logging and control state storage.
For engineers reviewing the CY15V102QN-50SXE datasheet, CY15V102QN-50SXE pinout, CY15V102QN-50SXE application, or CY15V102QN-50SXE equivalent, key selection considerations include its 50 MHz SPI timing compliance, 1.71–1.89 V low-voltage operation, hardware/software write protection scheme, dedicated 256-byte reflow-survivable special sector, and automotive-grade reliability without write latency.
Technical Context
The CY15V102QN-50SXE implements a true SPI slave interface compliant with Modes 0 and 3, enabling zero-latency byte-level writes at bus speed-no polling or erase cycles required. Its ferroelectric memory array eliminates the wear-out mechanisms of flash/EEPROM while maintaining pin- and command-level compatibility with standard SPI serial memory protocols.
It integrates a nonvolatile status register, device ID (manufacturer + product ID), unique ID, and user-writable 8-byte serial number registers. The dedicated 256-byte special sector retains data through up to three standard reflow soldering cycles, supporting board-level traceability in automotive manufacturing.

Equivalent & Alternatives
The following parts are listed as comparable options for similar nonvolatile serial memory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CY15B102QN-50SXE | Wider VDD range (1.8–3.6 V); identical pinout, timing, and memory architecture | Supports 3.3 V systems but lacks 1.8 V optimization; lower noise margin at 1.8 V vs. CY15V102QN | Select CY15B102QN only if system uses 2.5–3.3 V supply or requires backward voltage compatibility |
| FM25V02A-G | Cypress (now Infineon) 2 Mb F-RAM; same 1.7–1.9 V range and 50 MHz SPI, but no special sector or serial number registers | Lacks reflow-survivable sector and unique ID; limited traceability features for automotive Tier 1 requirements | Choose FM25V02A-G only for cost-sensitive non-automotive industrial use where calibration persistence isn't required |
Compared with CY15B102QN-50SXE and FM25V02A-G, the CY15V102QN-50SXE uniquely combines 1.8 V optimization, AEC-Q100 Grade 1 qualification, dedicated reflow-tolerant sector, and full traceability registers-making it the only choice for ASIL-B–aligned automotive data retention.

FAQ
Is CY15V102QN-50SXE pin-compatible with standard SPI EEPROM or flash devices?
Yes-it uses the industry-standard 8-pin SOIC package and SPI command set (including Read, Write, WREN, WRDI, RDSR) with identical pin functions (CS, SCK, SI, SO, WP, VDD, VSS). No hardware redesign is needed when replacing legacy serial nonvolatile memory in automotive ECUs, though firmware must disable polling loops due to zero-write-latency operation.
What is the purpose of the DNU pin, and how should it be handled on the PCB?
The DNU (Do Not Use) pin has no internal connection and must not be bonded or routed. Infineon specifies it may be left floating or tied to VDD-both options meet electrical specifications. PCB layout should omit any trace or pad connection to avoid accidental coupling; leaving it unconnected simplifies assembly and avoids potential noise injection paths.
How does the 256-byte special sector differ from main memory in terms of reliability and usage?
The special sector is physically isolated and optimized to retain data through up to three JEDEC J-STD-020-compliant reflow soldering cycles (peak 260°C), unlike main memory which is not characterized for reflow survival. It is accessed via dedicated opcodes (0x77/0x78) and intended for board-specific identifiers or factory calibration data that must persist after PCB assembly.
Does CY15V102QN-50SXE support dual-I/O or quad-I/O SPI modes?
No-it supports only standard single-data-line SPI in Modes 0 and 3 (CPOL=0/1, CPHA=0/1). It does not implement Dual Output, Dual Input, or Quad I/O instructions. All data transfers occur on SI (input) and SO (output) pins separately, with no multiplexed bidirectional data lines or extended opcode sets for higher bandwidth.
