BY25Q64ESTIG(T)

Memory IC Overview

The BY25Q64ESTIG(T) is a 64M-bit SPI NOR Flash memory by BYTe Semiconductor. It supports Standard, Dual, and Quad SPI interfaces with clock rates up to 100MHz (Normal Read) and 120MHz (Fast Read). Data transfer speeds reach 240Mbits/s for Dual I/O and 480Mbits/s for Quad I/O. Operating voltage is 2.7V to 3.6V. The device features XIP capability, page programming up to 256 bytes, and sector/block/chip erase functions. It includes hardware/software write protection, three 1024-byte security registers, and operates within -40°C to +85°C.

Memory IC Procurement Notes

Verify the ordering suffix 'T' corresponds to tube packaging when sourcing. Confirm the specific temperature grade required, as industrial ranges vary. Ensure the host system supports the necessary SPI modes for optimal performance. Check RoHS compliance status against current regulatory requirements.

Memory IC Selection Notes

Select this component for applications requiring high-speed data access via Quad I/O or QPI modes. Consider the 8-SOP package constraints for PCB layout. Evaluate power consumption needs, noting active and standby currents. Verify compatibility with existing SPI controllers supporting dual/quad protocols.

Memory IC Part Context

This part belongs to the BY25Q64ES family of 64M-bit SPI NOR Flash memories. It shares functional similarities with other BYTe Semiconductor flash devices but offers specific interface speeds and package options. The 'T' suffix indicates tube packaging, distinct from tape-and-reel variants.

Memory IC FAQ

What is the maximum clock rate for Fast Read operations?

The Fast Read (Serial) instruction supports a clock rate of 120MHz with a 30pF load.

How does the /HOLD pin function in Quad mode?

When the Quad Enable (QE) bit is set to 1, the /HOLD function is disabled, and the pin acts as a dedicated data I/O pin (IO3).
