BY25Q16ESSJG(T)

Memory IC Overview

The BY25Q16ESSJG(T) is a 16M-bit SPI NOR Flash memory by BYTe Semiconductor in an 8-SOP package. It supports standard, Dual, and Quad SPI interfaces with QPI mode, enabling data transfer rates up to 432 Mbits/s at clock frequencies of 108 MHz. The device operates on a single 2.7V to 3.6V supply and features uniform sector architecture (4KB sectors, 32/64KB blocks). Key specifications include typical page program times of 0.16ms, sector erase times of 20ms, and block erase times of 0.055s or 0.2s. It offers hardware/software write protection, three 1024-byte security registers, and supports Execute In Place (XIP) operations.

Memory IC Procurement Notes

Verify the specific suffix 'SJG' against official BYTe Semiconductor documentation to confirm pinout compatibility and package dimensions, as ordering suffixes define physical characteristics. Ensure the required temperature range matches the component's industrial rating. Confirm availability status as components may be subject to order-based manufacturing rather than immediate stock availability.

Memory IC Selection Notes

Select this component when a 16M-bit capacity is required with support for high-speed Quad I/O and QPI interfaces. It is suitable for applications needing XIP capabilities and robust write protection features. Consider the 8-SOP package constraints and verify that the operating voltage range of 2.7V to 3.6V aligns with the system power supply design.
