Product details
Overview
CY15B104QSN-108LPXI from Infineon is a 4-Mbit ferroelectric RAM (F-RAM) organized as 512K × 8, supporting quad SPI (QPI) up to 108 MHz SDR and 54 MHz DDR, with 100 trillion (10¹⁴) read/write endurance, 151-year data retention, and industrial temperature range (–40°C to +85°C). It serves as a high-speed, non-volatile memory replacement for serial flash or EEPROM in real-time data logging and control systems requiring instant write capability without polling.
For engineers reviewing the CY15B104QSN-108LPXI datasheet, CY15B104QSN-108LPXI pinout, CY15B104QSN-108LPXI application, or CY15B104QSN-108LPXI equivalent, key selection criteria include guaranteed 108 MHz SDR QPI timing, hardware/software write protection, on-die ECC for 1-bit correction per 8-byte unit, CRC-based data integrity verification, and support for deep power-down mode (0.80 µA typical).
Technical Context
The CY15B104QSN-108LPXI implements a true RAM-like interface over quad SPI, enabling execute-in-place (XIP) reads and immediate byte-level writes without erase cycles or write latency. Its ferroelectric core eliminates wear leveling and page programming overhead inherent in flash.
It supports SPI modes 0 and 3 for SDR transfers and mode 0 only for DDR, with configurable latency codes (MLC, RLC), quad/dual/single I/O protocols, and dedicated 256-byte special sector surviving three reflow cycles. Embedded ECC and CRC operate transparently during memory access.

IC Role / Device Role / Timing Role: Lossless waveform buffer preserving millisecond-accurate timing; powered from backup capacitor. Use Value: Deep power-down current (0.80 µA) extends hold-up time; instant write ensures no sample drop during AC failure. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar non-volatile memory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CY15B104QSN-108LAXI | Same die, 8-pin GQFN package (NRND); no SOIC footprint compatibility | Used in space-constrained PCBs where SOIC is not viable; requires redesign for thermal and routing | Select only if GQFN is mandated and NRND status is accepted for new designs |
| FM25V20A-G | 2-Mbit F-RAM, 40 MHz SPI max, no DDR/QPI, no on-die ECC or CRC | Limited to lower-bandwidth logging; lacks error detection and advanced protocol support | Choose when cost sensitivity outweighs speed, integrity, and density requirements |
Compared with CY15B104QSN-108LPXI, the GQFN variant sacrifices SOIC compatibility for size reduction, while the FM25V20A-G trades bandwidth, error resilience, and density for legacy design continuity and lower unit cost.

FAQ
Does CY15B104QSN-108LPXI require external high-voltage programming or erase pulses?
No. Unlike EEPROM or flash, this F-RAM uses standard 1.8–3.6 V supply for all operations. Writes occur at bus speed with no erase cycle, no high-voltage pump, and no write latency - data is non-volatile immediately after the SPI transaction completes.
Can the dedicated 256-byte special sector be used for secure key storage?
Yes. The special sector retains content through three Pb-free reflow cycles and supports standard read/write commands. Its physical separation and reflow survivability make it suitable for factory-programmed cryptographic keys, calibration coefficients, or device-unique identifiers.
How does the on-die ECC interact with normal read operations?
ECC operates transparently during reads: each 8-byte access triggers automatic 1-bit correction if detected, with no software intervention. A 2-bit error sets the ECC status flag but does not corrupt the read data - the host must check the status register after critical reads.
Is quad SPI (QPI) mode enabled by default after power-on reset?
No. QPI mode must be explicitly enabled via Configuration Register 2 (CR2[6]). Power-on defaults to standard single-I/O SPI. The device supports mode switching dynamically, but host firmware must configure CR2 and issue appropriate entry/exit commands per the datasheet sequence.
