CY15B004Q-SXE

CY15B004Q-SXE is a Cypress/Infineon serial memory device from the CY15B0x family. It provides non-volatile storage accessible via a standard SPI-compatible interface, suitable for embedded systems to store configuration, calibration data, logs, or firmware imagery.
Key points:
- SPI slave interface (CS, SCK, SI, SO); optional WP and HOLD pins.
- Small 8-pin package; typical supply in the 2.7–3.6 V range (variants exist).
- Memory size and organization shown in the datasheet (commonly megabit range, e.g., 4 Mb; exact layout per datasheet).
- Features like page-write, fast read, and data retention with specified endurance/calibration in the application note.
- Used in automotive/industrial environments due to wide temperature ranges in many variants.
For exact specifications (capacity, voltage, timing, endurance, package options), refer to the official datasheet. If you share your board context or a link, I can pull the precise pins, voltages, and timings.

CY15B004Q-SXE is a Cypress memory device. To give precise cross‑references I need its exact density/type and speed, voltage, and package. Are you seeking equivalents from ISSI, Alliance Memory, Winbond, etc., and can I perform a quick web lookup for exact cross‑reference part numbers? Please provide speed (ns), supply voltage (V), package, and temperature grade or a link to the datasheet.

Pin count: 8 pins (8-pin package, e.g., SOIC).
