W25Q64JVSSIQ | Winbond Electronics | Serial NOR Flash Memory IC (SPI Flash)

Key Specifications

Memory Capacity: 64Mbit (8MB)

Communication Interface: Standard SPI, Dual-SPI, Quad-SPI and QPI. Max clock frequency 133MHz; equivalent maximum read speed up to 532MHz under Quad mode.

Operating Voltage: 2.7V ~ 3.6V (Compatible with 3.3V MCU systems such as STM32 series)

Operating Temperature: -40℃ ~ +85℃ (Industrial grade, non-automotive)

Program/Erase Endurance: Minimum 100,000 program-erase cycles

Data Retention: ≥20 years of data storage when power is off

Memory Block Organization: 4KB sector / 32KB block / 64KB block; page size 256Byte (256 bytes per programming operation)

Package: SOIC-8 (208mil) SMD. SS = SOIC8; IQ = industrial temperature version

Power Consumption: Max. 25mA during read operation; standby current only 1μA in power-down mode

Packaging: Tape-and-Reel (T&R), RoHS compliant

Main Features

Firmware / Program Storage: External Flash for MCUs to store firmware. Supports XIP (Execute In Place), which allows code to run directly from Flash without full copying to RAM. Ideal as external storage for main controllers such as STM32H7/F4.

Flexible Partition Erase: Supports independent erasure of 4KB small sectors. Parameters, logs and calibration data can be saved separately without full-chip erasure.

Multi-level Write Protection: Hardware write-protect pin plus software register write protection to avoid accidental firmware erasure; integrated power-on reset.

Unique ID Serial Number: Built-in 64-bit unique identifier for device encryption, identity recognition and anti-counterfeiting.

High-speed Quad SPI: Greatly improves read speed and shortens device boot time.

Low-power Mode: Sleep mode suitable for battery-powered portable devices.
