W25Q80BV - 1 MByte SPI Flash
Discontinued
The W25Q80BV is a 1 MB (8 Mbit) SPI flash memory chip in a DIP-8 package. It provides non-volatile storage for microcontroller projects — ideal for data logging, storing configuration, fonts, images, or audio samples where an SD card would be overkill.
Communication is via standard SPI, making it compatible with virtually any microcontroller. The chip operates at 3.3 V, so a logic level shifter is required when using 5 V boards such as the Arduino Uno.
Key Features
- 1 MB (8 Mbit) Storage – Solid-state, non-volatile flash memory
- SPI Interface – Standard 4-wire SPI (up to 104 MHz clock)
- DIP-8 Package – Breadboard-friendly through-hole format
- Low Power – Active read ~4 mA; standby ~1 µA
- Sector/Block Erase – 4 KB sector, 32 KB/64 KB block, or full chip erase
- 100,000 Erase Cycles – Long-lasting storage with 20-year data retention
Specifications
- Capacity: 1 MB (8 Mbit)
- Interface: SPI (up to 104 MHz)
- Supply Voltage: 2.5–3.6 V
- Package: DIP-8
- Manufacturer: Winbond
Ideal For
- Data logging and configuration storage
- Storing fonts, images, or audio for embedded displays and speakers
- CircuitPython and Arduino projects needing external flash
Note: This is a 3.3 V part. Use a logic level shifter (e.g., 74LVC245 or BSS138-based bidirectional converter) when connecting to 5 V microcontrollers.
