Memory IC Overview

The BY25Q80BSTJG(R) is an 8M-bit Serial Peripheral Interface (SPI) NOR Flash memory manufactured by BYTe Semiconductor. It supports Standard, Dual, and Quad SPI modes as well as the Quad Peripheral Interface (QPI). The device operates on a single voltage supply ranging from 2.7V to 3.6V. It features flexible architecture with 4KB sectors and 32/64KB blocks. Key performance metrics include a normal read clock rate of 55MHz and a fast read rate of 108MHz. Data transfer speeds reach up to 216Mbits/s in Dual I/O mode and 432Mbits/s in Quad I/O mode. The component offers typical endurance of 100k program-erase cycles and data retention of 20 years.

Memory IC Feature Summary

• Supports multiple interface modes including Standard SPI, Dual SPI, Quad SPI, and QPI for flexible system integration.
• Enables Execute In Place (XIP) operation allowing continuous code execution directly from the flash memory.
• Provides comprehensive write protection mechanisms via software commands and hardware /WP pin control.
• Includes three 256-byte security registers with One-Time Programmable (OTP) lock capabilities.

Memory IC Applications

• Firmware storage for embedded systems requiring direct code execution
• Data logging applications needing reliable non-volatile storage
• Industrial control systems operating within specified temperature ranges

Memory IC Procurement Notes

Verify the specific package variant corresponding to the BSTJG suffix against official ordering information. Confirm that the required temperature grade matches the commercial or industrial specifications listed in the datasheet. Ensure compatibility with the host controller's SPI interface modes, particularly if utilizing Quad I/O or QPI functions which require specific status register configurations.

Memory IC Selection Notes

Select this component when an 8M-bit capacity is required with support for high-speed Quad I/O and QPI operations. Consider the available package options such as SOP8 or TSSOP8 based on board space constraints. Evaluate the need for hardware write protection features and the specific voltage requirements of the target application to ensure alignment with the 2.7V to 3.6V operating range.
