Memory IC Overview

The BY25Q40BSSIG(T) is a 4M-bit SPI NOR Flash memory from BYTe Semiconductor. It supports Standard, Dual, Quad SPI, and QPI interfaces with read speeds up to 108MHz (Fast Read Serial). The device operates on a single supply voltage of 2.7V to 3.6V. Key features include page programming up to 256 bytes, sector/block/chip erase capabilities, and flexible software/hardware write protection. It offers typical endurance of 100k program-erase cycles and 20-year data retention.

Memory IC Feature Summary

Supports multiple interface modes including Standard, Dual, Quad SPI, and QPI for optimized data transfer rates.
Provides comprehensive write protection mechanisms via hardware /WP pin control and software status register configuration.
Features low power consumption with active current of 20mA maximum and standby current of 5uA maximum.
Includes three 256-byte security registers with One-Time Programmable (OTP) lock capability.

Memory IC Applications

Embedded systems requiring non-volatile code storage
Consumer electronics firmware storage
Industrial control system data logging
IoT devices needing secure boot code

Memory IC Procurement Notes

Verify the specific suffix 'IG' corresponds to the USON-8 package when ordering. Confirm temperature grade requirements against commercial or industrial specifications. Ensure voltage compatibility with the 2.7V to 3.6V operating range. Check for RoHS compliance status if required by your manufacturing standards.

Memory IC Selection Notes

Select this component for applications requiring high-speed Quad I/O access and QPI mode support. Consider the 2.7V minimum supply voltage for low-power designs. Evaluate the need for hardware write protection via the /WP pin versus software-only protection schemes based on system security requirements.

Memory IC Part Context

This part belongs to the BY25Q40BS series of 4M-bit SPI NOR Flash memories.
