Product details
Overview
CY15B104QSN-108BFXIT 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-reliability, instant-write non-volatile memory for real-time data logging in programmable logic controllers.
For engineers reviewing the CY15B104QSN-108BFXIT datasheet, CY15B104QSN-108BFXIT pinout, CY15B104QSN-108BFXIT application, or CY15B104QSN-108BFXIT equivalent, key selection considerations include its 1.8 V–3.6 V supply range, on-die ECC/CRC error handling, hardware write protection via WP pin, and dedicated 256-byte reflow-survivable special sector for critical configuration storage.
Technical Context
The CY15B104QSN-108BFXIT implements a serial peripheral interface compliant with SPI modes 0 and 3 for SDR transfers and mode 0 only for DDR transfers. Its command set includes WREN/WRDI for write enable control, RDSR1/RDSR2 for status monitoring, and WRAR/RDAR for flexible register access.
It integrates dual status registers (SR1/SR2), five configuration registers (CR1–CR5), and supports extended features including memory latency code (MLC), quad data width (QUAD), QPI enable (CR2[6]), and deep-power-down mode activation (CR4[2]). CRC suspend/abort (SR2[4:3]) enables controlled integrity checking during active writes.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory density | 4 Mbit (512K × 8), enabling compact firmware parameter storage without external address latching |
| Interface speed | Up to 108 MHz SDR / 54 MHz DDR SPI, delivering up to 432 MB/s effective throughput in QPI mode |

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 |
|---|---|---|---|
| CY15B104QSN-108BFXI | Same die, identical specs, but in 8-pin GQFN package (NRND status per Infineon documentation) | Requires different PCB layout and reflow profile; not recommended for new designs due to NRND designation | Select only if legacy GQFN footprint reuse is mandatory and supply chain risk is mitigated |
| FM25V04-G | 4-Mbit F-RAM with 40 MHz max SPI speed, no DDR/QPI support, 1.7–2.2 V supply only | Limited to lower-bandwidth applications; lacks ECC/CRC and dedicated special sector | Choose when cost sensitivity outweighs speed, data integrity, and reflow survivability requirements |
Compared with CY15B104QSN-108BFXI and FM25V04-G, the CY15B104QSN-108BFXIT delivers superior bandwidth (108 MHz vs ≤40 MHz), broader voltage compatibility (1.8–3.6 V), and enhanced reliability features (ECC/CRC, reflow-hardened sector), making it optimal for next-generation industrial and medical edge devices.

FAQ
What is the maximum supported SPI clock frequency for CY15B104QSN-108BFXIT in QPI SDR mode?
The device supports up to 108 MHz SPI clock frequency in quad SPI single data rate (QPI SDR) mode, delivering 432 MB/s effective throughput. This rating is specified under VDD = 1.8–3.6 V and TA = –40°C to +85°C, with setup/hold timing validated per Infineon's AC characteristics table in Rev. *O datasheet.
Does CY15B104QSN-108BFXIT require external high-voltage programming or erase pulses?
No. Unlike flash or EEPROM, this F-RAM performs true random-access reads and writes at bus speed with no erase cycles, high-voltage pulses, or write latency. Each byte writes instantly upon successful transfer - verified by immediate WIP flag clearing in SR1[0] without polling.
How does the dedicated 256-byte special sector differ from main memory in terms of reflow tolerance?
The special sector retains data through up to three standard Pb-free reflow cycles (JEDEC J-STD-020), whereas main array data may degrade after one cycle. This is achieved via process-level hardening and separate write control - confirmed in the "Special Sector F-RAM" section of the functional description.
Can the unique ID and serial number be overwritten after factory programming?
No. The unique ID is laser-trimmed during wafer test and permanently fixed. The user-programmable serial number is written once via WRAR command (71h) to CR4-mapped registers and becomes read-only thereafter - enforced by hardware fuse logic and documented in Section 4.2.3 of the datasheet.
