BY25Q64ESHIG(R)

Memory IC Overview

The BY25Q64ESHIG(R) is a 64 Mbit SPI NOR Flash memory manufactured by BYTe Semiconductor. It supports Standard, Dual, and Quad SPI interfaces with clock rates up to 100 MHz for normal read and 120 MHz for fast read. The device operates on a single 2.7 V to 3.6 V supply voltage and features uniform sector architecture with 4 KB sectors and 32/64 KB blocks. It includes hardware and software write protection mechanisms, three 1024-byte security registers, and supports Execute In Place (XIP).

Memory IC Feature Summary

• Supports standard, dual, and quad SPI modes for flexible data transfer speeds.
• Features comprehensive write protection including block protect bits and hardware /WP pin control.
• Includes three 1024-byte security registers with One-Time Programmable (OTP) lock capabilities.
• Enables Execute In Place (XIP) operation for direct code execution from the flash memory.

Memory IC Applications

• Firmware storage for microcontrollers and embedded systems.
• Code execution in place (XIP) applications.
• Data logging and configuration storage.
• Boot code storage for IoT devices.

Memory IC Procurement Notes

Verify the specific package variant required, as the datasheet lists SOP8, USON8, WSON8, and LGA8 options. Confirm the suffix 'HIG' corresponds to the intended temperature range and packaging format with the manufacturer. Ensure compatibility with host system voltage levels within the 2.7V to 3.6V operating range before integration.

Memory IC Selection Notes

Select this component when a 64 Mbit capacity is required with support for high-speed Quad SPI operations. It is suitable for designs needing robust write protection via hardware pins or software commands. Consider the available package types such as SOP8 or WSON8 based on PCB space constraints and thermal requirements.

Memory IC Part Context

This part belongs to the BY25Q64ES family of Serial Peripheral Interface Flash memories. It is designed for non-volatile data storage in consumer electronics, industrial controls, and communication equipment. The series offers various package options to accommodate different board layout needs while maintaining consistent electrical performance across the product line.

Memory IC Replacement Considerations

Check for compatible parts from other manufacturers offering 64 Mbit density with similar SPI interface specifications. Verify pinout compatibility and voltage ranges if substituting with parts from different vendors. Ensure that any replacement supports the required Quad SPI mode and security register features if these are critical to the design.
