Item specifics
Description
The W25Q64JVSSIQ is a 64Mbit (8MB) Serial NOR Flash memory from Winbond's SpiFlash® family, housed in a standard SOIC-8-208mil package. It supports standard SPI, Dual-SPI, and Quad-SPI interfaces with a maximum clock frequency of 133MHz, achieving an equivalent transfer rate of 532MHz (66MB/s) in Quad-SPI mode. Operating from 2.7V to 3.6V with a temperature range of -40℃ to +85℃, the device features 10μA standby current and 1μA power-down current, and supports Execute-In-Place (XIP) directly from the SPI interface. The W25Q64JVSSIQ is widely used in embedded systems, industrial controllers, IoT gateways, networking equipment, and consumer electronics.
133MHz High-Speed Clock, 532MHz Equivalent in Quad-SPI: Supports clock frequencies up to 133MHz, achieving an equivalent 532MHz (66MB/s) transfer rate in Quad-SPI mode, significantly reducing MCU boot time and enabling Execute-In-Place (XIP) or code shadowing to RAM.
64Mbit Large Capacity: 64Mbit (8MB) organized into 32,768 programmable pages of 256 bytes each. Supports 4KB sector erase, 32KB block erase, 64KB block erase, and full chip erase, with 2,048 erasable sectors and 128 erasable blocks.
Q-suffix with Pre-enabled Quad I/O: The W25Q64JVSSIQ has the QE bit fixed at 1, allowing Quad I/O commands to be used directly without programming the QE bit, simplifying firmware development. Note that the /HOLD function is unavailable on this version.
Low Power Design: Single 2.7V to 3.6V power supply with 10μA typical standby current and 1μA power-down current, ideal for battery-powered portable devices and low-power IoT applications.
High Reliability & Data Retention: 100,000 program/erase cycles, 20-year data retention, and 3ms page programming time (0.4ms typical) for reliable data storage in industrial applications.
Comprehensive Security Protection: Supports software write protection, hardware write protection (WP# pin), and absolute write protection. Three 256-byte Security Registers with OTP permanent lock via Security Register Lock Bits (LB3-1) in Status Register-2.
SOIC-8-208mil Standard Package: 5.28×5.28×2.16mm body, MSL Level 3 (168 hours), RoHS compliant, compatible with mainstream PCB design standards.
