BY25Q16ESSIG(T)

Memory IC Overview

The BY25Q16ESSIG(T) is a 16M-bit SPI NOR Flash memory by BYTe Semiconductor, housed in an 8-SOP package. It supports Standard, Dual, and Quad SPI interfaces, along with QPI mode for up to 432 Mbits/s data transfer at 108 MHz clock rates. Operating on a single 2.7V to 3.6V supply, it features XIP capability, hardware/software write protection, and three 1024-byte security registers. The device operates within -40°C to +85°C temperature range.

Memory IC Feature Summary

• Supports standard, dual, quad SPI, and QPI modes for high-speed data access
• Enables Execute In Place (XIP) operation via continuous read mode
• Includes hardware and software write protection mechanisms
• Features three 1024-byte security registers with OTP locks

Memory IC Applications

• Firmware storage in embedded systems
• Code execution from flash (XIP)
• Data logging applications
• Consumer electronics firmware

Memory IC Procurement Notes

Verify the specific suffix 'SIG' against official BYTe documentation to confirm pinout and package dimensions. Ensure the operating voltage range of 2.7V to 3.6V matches the target system design. Confirm that the required interface modes (SPI/QPI) are supported by the host controller.

Memory IC Selection Notes

Select this component when a 16M-bit capacity is required with support for high-speed Quad I/O and QPI operations. It is suitable for designs needing XIP capabilities and robust write protection features. Verify compatibility with existing SPI controllers regarding clock frequency limits and instruction set support.

Memory IC Part Context

This part belongs to the BY25Q16ES family of SPI NOR Flash memories. It shares core architectural features with other members of the series but differs in packaging and specific electrical characteristics defined by its suffix. It is designed for low-power, high-performance non-volatile storage needs.
