BY25D16ASTJG(R)

Memory IC Overview

The BY25D16ASTJG(R) is a 16M-bit SPI NOR Flash memory from BYTe Semiconductor. It supports Standard and Dual SPI interfaces, with Dual Output data transfer speeds reaching 108 Mbits/s. The device operates on a single supply voltage ranging from 2.7V to 3.6V. Key performance metrics include a typical page program time of 0.7ms, sector erase time of 100ms, block erase times of 0.3s or 0.5s, and chip erase time of 15s. It offers flexible architecture with 4KB sectors and 32/64KB blocks, ensuring 100k program-erase cycles and 20-year data retention.

Memory IC Feature Summary

• Supports Dual SPI operation for high-speed data transfer using bidirectional I/O pins.
• Provides hardware and software write protection mechanisms via the /WP pin and status register bits.
• Features low power consumption with maximum active current of 20mA and standby current of 5uA.
• Includes a unique 64-bit factory-set ID number for system security and anti-cloning purposes.

Memory IC Applications

• Battery-powered devices requiring deep power-down modes for extended battery life.
• Systems needing secure storage with unique device identification capabilities.
• Applications requiring flexible memory protection for critical code or data sectors.

Memory IC Procurement Notes

Verify the specific package type (e.g., TSSOP, SOP) associated with the suffix 'TJG' against the manufacturer's official ordering information sheet, as datasheets may list multiple valid packages for the base part number. Confirm temperature range requirements match the commercial or industrial grades specified in the final product marking. Ensure compatibility with dual SPI controllers if utilizing the high-speed read features.

Memory IC Selection Notes

Select this component when Dual SPI interface speed is required but Quad SPI is not necessary. It is suitable for designs operating within the 2.7V to 3.6V voltage range. Consider the 100k cycle endurance and 20-year retention for long-life applications. Verify that the available package options meet the PCB layout constraints and thermal requirements of the target environment.

Memory IC Part Context

This part belongs to the BY25D16AS family of 16M-bit SPI NOR Flash memories. It shares architectural similarities with other BYTe Semiconductor flash parts but is distinct in its density and interface support. The 'AS' designation typically refers to the specific feature set including Dual SPI support and standard instruction set compatibility found in this series.

Memory IC Replacement Considerations

Publicly confirmed substitute part numbers are not explicitly listed in the provided source material for this specific variant. Users should consult the manufacturer's cross-reference documentation or contact BYTe Semiconductor directly for verified equivalent components.
