BY25Q80AWTIG(R)

Memory IC Overview

The BY25Q80AW is an 8 Mbit SPI NOR flash memory with a 1M x 8 organization. It operates on a single supply voltage ranging from 1.65 V to 3.6 V. The device supports standard, dual, and quad SPI interfaces with maximum clock frequencies of 65 MHz for normal reads and 100 MHz for other read modes. It features flexible erase architectures including 4 KB sectors and 32/64 KB blocks. The component provides software and hardware write protection mechanisms and includes three 512-byte security registers.

• Features flexible erase architecture with 4 KB sector and 32/64 KB block granularity.
• Includes comprehensive write protection via hardware /WP pin and software status register bits.
• Integrates three 512-byte security registers with one-time programmable lock functionality.

Memory IC Applications

• Code shadowing into embedded or external RAM for execution
• General-purpose data storage applications
• Consumer-based electronic devices requiring non-volatile memory

Memory IC Procurement Notes

Verify the specific package variant required, as the datasheet lists SOP8, TSSOP8, DFN2x3mm, DFN1.5x1.5mm, and USON8 options. Confirm temperature range compliance, noting distinctions between commercial (0°C to +70°C) and industrial (-40°C to +85°C) grades. Ensure the ordering suffix matches the desired physical footprint and operating specifications.

Memory IC Selection Notes

Select this component when a wide voltage range down to 1.65 V is necessary for low-power systems. Choose the industrial grade version if operation below 0°C is required. Consider the Quad SPI mode for higher throughput needs compared to standard SPI. Verify that the 8 Mbit density aligns with system code and data storage requirements without excessive waste.

Memory IC Part Context

This part belongs to the BY25Q80 series of SPI NOR flash memories manufactured by BYTe Semiconductor. It shares architectural similarities with other industry-standard SPI flash devices but offers a unique wide voltage range starting at 1.65 V. The series supports various package types to accommodate different PCB layout constraints in consumer electronics.

Memory IC Replacement Considerations

Check for compatible parts within the same density class that support the 1.65 V minimum voltage requirement. Verify pinout compatibility if replacing in existing designs, particularly regarding the shared IO pins for Dual/Quad modes. Ensure the replacement supports the required Quad SPI enable bit configuration.
