BY25D80ASOIG(T)

Memory IC Overview

The BY25D80ASOIG(T) is an 8M-bit SPI NOR Flash memory manufactured by BYTe Semiconductor. It supports Standard and Dual SPI interfaces, offering read speeds up to 108MHz in Fast Read and Dual Output modes. The device operates on a single 2.7V to 3.6V supply and features flexible architecture with 4KB sectors and 32/64KB blocks. It includes hardware and software write protection, low power consumption (5uA standby), and robust endurance of 100k program-erase cycles with 20-year data retention.

Memory IC Feature Summary

• Supports Dual SPI operation for high-speed data transfer using bidirectional I/O pins.
• Provides flexible memory protection via hardware /WP pin and software Block Protect bits.
• Features a unique factory-set 64-bit ID number for system security and anti-cloning.
• Includes Deep Power-Down mode to minimize current consumption in battery-powered applications.

Memory IC Applications

• Battery-powered portable devices requiring low standby current
• Systems needing hardware-enforced code protection
• Applications utilizing Dual SPI interface for increased bandwidth

Memory IC Procurement Notes

Verify the specific package suffix 'OIG' against official ordering information, as datasheets list SOP8, TSSOP8, and USON8 variants. Confirm temperature range requirements match Commercial or Industrial grades. Ensure voltage supply stability during power-up to trigger the internal POR circuit correctly.

Memory IC Selection Notes

Select this component when Dual SPI speed is required within a standard 8-pin footprint. Compare page program times and block erase durations against application latency needs. Verify that the 2.7V-3.6V operating range aligns with the system's power rail capabilities.

Memory IC Part Context

This part belongs to the BY25D80 family of 8M-bit SPI NOR Flash memories. It shares core electrical characteristics and instruction sets with other density variants in the series, differing primarily in capacity and potentially package options. The 'AS' designation typically indicates specific performance or package attributes within the BYTe product line.

Memory IC Replacement Considerations

Check for exact pin-compatible alternatives from BYTe or other manufacturers supporting Dual SPI. Verify that substitute parts offer comparable 108MHz read speeds and similar write protection mechanisms. Ensure the replacement supports the same 2.7V-3.6V voltage range and industrial temperature specifications if required.

Memory IC FAQ

How does the Dual SPI interface improve performance?

Dual SPI allows data to be transferred at twice the rate of standard SPI by using both SI and SO pins simultaneously during Fast Read operations, achieving up to 108MHz effective throughput.

What is the function of the Unique ID Number?

The 64-bit Unique ID is factory-programmed and read-only, used to prevent system cloning or copying by providing a distinct identifier for each device.
