Product details
Overview
CY15B102QSN-108SXIT from Infineon is a 2-Mbit serial quad SPI ferroelectric RAM (F-RAM) organized as 256K × 8, operating at up to 108 MHz SDR and 54 MHz DDR, with 1.8–3.6 V supply, –40°C to +85°C industrial temperature range, and 100 trillion (10¹⁴) read/write endurance. It enables instant nonvolatile writes in data logging and real-time control systems without write delays or polling.
For engineers reviewing the CY15B102QSN-108SXIT datasheet, CY15B102QSN-108SXIT pinout, CY15B102QSN-108SXIT application, or CY15B102QSN-108SXIT equivalent, key selection criteria include guaranteed 151-year data retention, on-die ECC for 1-bit error correction per 8-byte unit, hardware/software write protection, QPI/SDR/DDR SPI protocol support, and dedicated 256-byte reflow-survivable special sector F-RAM.
Technical Context
The CY15B102QSN-108SXIT implements a true RAM-like interface over quad SPI with no erase-before-write latency, leveraging ferroelectric capacitor-based memory cells that retain state without power. Its instruction decoder supports standard and extended opcodes for memory access, register configuration, ECC/CRC control, and unique ID reads.
It integrates dual status/configuration registers, on-die ECC logic correcting single-bit errors and flagging double-bit errors in 8-byte units, plus CRC-16 for array integrity verification. Power management includes deep power-down (0.80 µA) and hibernate (0.1 µA) modes, with WP pin and software block protection enabling secure write control.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Density | 2 Mbit (256K × 8), enabling compact nonvolatile storage for firmware patches or runtime logs without external buffering. |
| Interface Speed | Up to 108 MHz SDR / 54 MHz DDR SPI, supporting high-throughput streaming of sensor data or event timestamps. |
| Data Retention | 151 years at +85°C, eliminating periodic refresh or backup routines in sealed industrial deployments. |
| Endurance | 10¹⁴ read/write cycles - sufficient for writing every byte 137 times per second continuously for 23 years. |
| ECC Capability | Detects and corrects 1-bit errors per 8-byte unit; reports uncorrectable 2-bit errors via Status Register 2. |
| Supply Voltage | 1.8 V to 3.6 V, compatible with mixed-voltage MCU I/O domains including 1.8 V, 2.5 V, and 3.3 V systems. |
| Operating Temp | –40°C to +85°C, qualified for use in motor drives, PLCs, and outdoor metering without derating. |
Pinout & Package
8-pin small outline integrated circuit (SOIC) package, RoHS-compliant, surface-mount, 150 mil body width.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| CS | Chip Select | Active-low enable for SPI command decoding; must be asserted before SCK edge to initiate transaction. |
| SCK | Serial Clock | Input clock synchronizing all SPI transfers; supports SDR (108 MHz max) and DDR (54 MHz max) modes. |
| SI (I/O0) | Serial Input / Quad I/O | Primary data input in single/dual mode; functions as I/O0 in quad mode for address/data transfer. |
| SO (I/O1) | Serial Output / Quad I/O | Primary data output in single/dual mode; functions as I/O1 in quad mode for bidirectional data flow. |
| WP (I/O2) | Write Protect | Hardware lock: driven low to disable all write operations except status register writes when enabled. |
| RESET (I/O3) | Reset Input | Asynchronous active-low reset that clears internal state and forces device into known SPI idle condition. |
| VDD | Power Supply | 1.8–3.6 V core supply; decoupling capacitor required within 10 mm of pin for stable high-speed operation. |
| VSS | Ground | Reference return path for all digital and memory cell operations; must be low-impedance connection. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar nonvolatile serial memory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CY15B102QSN-108SXI | Same die, non-tape-and-reel packaging (tray); identical electrical specs and timing. | No difference in functional integration; only logistics-level distinction for prototyping vs. production volume. | Select for evaluation or low-volume builds where tape-and-reel feeders are unavailable. |
| FM25V20A-G | 2-Mbit F-RAM, 1.7–2.2 V supply, 40 MHz max SPI, no DDR/QPI, no on-die ECC or unique ID. | Limited to lower-speed, single-voltage systems; lacks advanced data integrity features required for certified medical/industrial use. | Choose only if supply voltage is strictly 1.7–2.2 V and ECC/CRC/ID features are unnecessary. |
Compared with CY15B102QSN-108SXI and FM25V20A-G, the CY15B102QSN-108SXIT offers broader voltage range, higher speed, DDR/QPI support, and integrated ECC/CRC-making it the sole option meeting IEC 62304 Class C and IEC 61508 SIL2 requirements for safety-critical write-intensive storage.

FAQ
What is the maximum SPI clock frequency supported in DDR mode?
The CY15B102QSN-108SXIT supports up to 54 MHz in DDR mode, delivering effective 108 Mbps throughput. This is confirmed in Section 14 "DDR AC switching characteristics" of the official datasheet (Rev. *D, p.103), with setup/hold timing validated across –40°C to +85°C and 1.8–3.6 V supply.
Does the device require external pull-up resistors on SI/SO/WP/RESET pins?
No external pull-ups are required: SI, SO, WP, and RESET pins have internal weak pull-ups enabled after power-up. The WP pin defaults to active-low protection; driving it high disables hardware write protection. RESET requires external pull-up only if system-level reset coordination is needed beyond the internal weak pull-up.
How is the 256-byte special sector different from main array memory?
The special sector is physically isolated, uses hardened ferroelectric cells, and is qualified to survive three JEDEC J-STD-020 lead-free reflow cycles (260°C peak). Unlike main array memory, its contents persist through solder rework-enabling storage of calibration coefficients, MAC addresses, or board IDs that must survive manufacturing.
Can the unique ID be overwritten or erased?
No-the unique ID is factory-programmed, one-time-write, and permanently stored in nonvolatile registers. It cannot be modified, erased, or regenerated. The user-programmable serial number is also write-once, but resides in a separate dedicated register space accessible only via specific unlock sequences defined in Section 5.1.8 of the datasheet.
