BY25Q128ESSIG(R)

Memory IC Overview

The BY25Q128ESSIG(R) is a 128M-bit SPI NOR flash memory by BYTe Semiconductor, housed in an 8-SOP package. It supports standard, dual, and quad SPI interfaces with clock frequencies up to 133 MHz. Operating on a single 2.7V to 3.6V supply, it features 128Mb capacity organized as 16M x 8 bits. Key electrical parameters include a maximum active current of 10 mA, standby current of 2 µA, and data retention of 20 years. The device supports -40°C to +85°C commercial/industrial temperature ranges.

Memory IC Feature Summary

• Supports Dual and Quad SPI modes for high-speed data transfer
• Includes hardware and software write protection mechanisms
• Features Execute In Place (XIP) capability for direct code execution
• Provides flexible erase architecture with sector and block options

Memory IC Applications

• Embedded systems requiring non-volatile code storage
• Consumer electronics firmware storage
• Industrial control system data logging
• IoT devices needing low-power persistent memory

Memory IC Procurement Notes

Verify the specific suffix 'SIG' corresponds to the SOP-8 208mil package variant. Confirm the manufacturer is BYTe Semiconductor or authorized distributor. Check RoHS compliance status if required for your region. Ensure the datasheet revision matches the component marking for accurate timing specifications.

Memory IC Selection Notes

Select this part when a 128Mbit density is required with SOP-8 footprint constraints. Compare clock speeds against other 128Mb parts if higher throughput is needed. Consider power consumption profiles for battery-operated applications. Verify voltage compatibility with the host system's I/O levels.

Memory IC Part Context

This component belongs to the BY25Q128ES family of SPI NOR flash memories. It shares architectural similarities with other 128Mb devices but differs in packaging and specific electrical characteristics. The ES series typically denotes enhanced performance features compared to earlier generations.

Memory IC Replacement Considerations

GD25Q128ESIGR is a pin-compatible alternative from GigaDevice with similar specifications. BY25Q128ESSIG(T) offers the same functionality in tube packaging instead of tape and reel.
