W25R512JVEIN

Winbond W25R512JVEIN is a 512-Mbit Serial NOR Flash memory. It stores firmware and data in embedded systems and comes in an 8-pin package with a single 2.7–3.6 V supply.
Key points:
- Interface: Serial SPI, with optional dual/quad I/O modes for higher throughput (QPI/quad in some variants).
- Organization: 512 Mbit capacity; supports 256-byte page programming; 4 KB sectors; 32 KB/64 KB blocks; chip erase.
- Performance: Fast read modes; standard SPI clocking up to high speeds in supported modes; Write Enable Latch and status/config registers; hardware write protection.
- Features: Low‑power standby, basic security/OTP options (as supported by the device family), and multiple temperature grades (industrial/extended) depending on the lot.
- Applications: Boot code storage, firmware updates, code patches, and data logging in embedded systems (consumer, automotive, industrial).
In short, it’s a dense, versatile SPI NOR flash suitable for reliable non‑volatile storage in compact embedded designs.
