W25Q512JVFIM

The W25Q512JVFIM is Winbond’s 512‑Mbit serial flash memory (non-volatile) with an SPI interface. It is intended for storing firmware, code, and data in microcontroller systems and embedded devices.
Key points
- Density and voltage: 512 Mbit; typically operates from 2.7–3.6 V.
- Interface: Serial SPI (standard mode; some variants support faster/dual/quad I/O modes per variant).
- Memory organization: 4 KB sectors, 64 KB blocks (chip erase available).
- Performance and modes: Fast/readable SPI access, power-down and deep power-down modes.
- Endurance and retention: ~100,000 erase/program cycles per sector; data retention typically years.
- Package: 8-pin device package (SOP/SOIC variants common); industrial-grade option indicated by the “IM” suffix.
- Applications: Firmware storage, boot code, configuration data for embedded systems and consumer electronics.
Notes
- Always consult the latest Winbond datasheet for exact electrical specs, command set, timing, and the specific variant’s capabilities (in particular, dual/quad I/O modes and timing limits).
