概述

Description

W25R512JVEIN is Winbond’s 512‑Mbit serial NOR flash memory. It provides non-volatile firmware and data storage for embedded systems with a small pin count interface.
Key points
- Capacity: 512 Mbit (64 MBytes) of flash.
- Interface: SPI‑compatible; supports standard SPI and Dual/Quad I/O modes for higher throughput.
- Memory organization: supports fast read with dummy cycles; sector/block erases (4 KB/8 KB sectors, 64 KB and 256 KB blocks) and full‑chip erase.
- Commands and features: JEDEC standard command set; status register read/write; write protection (WP#); hold and reset; power‑down/deep power‑down modes.
- Reliability: typical endurance around 100k P/E cycles; data retention on the order of years (typical values in datasheets).
- Packaging: 8‑pin package (suffix VEIN indicates the specific package variant).
- Applications: firmware storage, boot ROM, and data storage in microcontroller/SoC systems requiring low pin count and reliable, non‑volatile memory.

Features

W25R512JVEIN is a 512‑Mbit serial NOR flash from Winbond. Key features:
- Density: 512 Mbit (64 MB) total
- Interface: Serial SPI with support for standard SPI, Dual I/O, Quad I/O, and QPI modes
- Supply: 2.7–3.6 V operation (typical 3.0 V systems)
- Organization: 256-byte pages
- Erase/_program: 4 KB sectors; 32 KB and 64 KB blocks; page programable (256 bytes per write)
- Read speed: high‑speed reads up to ~104 MHz (with appropriate dummy cycles for modes)
- Power: Deep power-down mode and low active/standby currents
- Security: block protection, write protection, and security features via protection registers
- Reliability: data retention commonly ~years; erase/program endurance on the order of 100k cycles per block (typical)
- Temperature: industrial grade operating range (-40 to 85 °C)
- Package: 8-pin package (JEDEC standard form factor)
Applications: firmware/boot code storage, embedded analytics, and data logging where dense, low‑voltage, high‑speed memory is needed.
