BY25Q16ESUJG(R)

Memory IC Overview

The BY25Q16ESUJG(R) is a 16M-bit Serial Peripheral Interface (SPI) NOR Flash memory manufactured by BYTe Semiconductor. It supports Standard, Dual, and Quad SPI modes as well as the Quad Peripheral Interface (QPI). The device operates on a single low-voltage power supply ranging from 2.7V to 3.6V. It features flexible architecture with 4KB sectors and 32/64KB blocks, allowing for granular erase operations. The memory supports Execute In Place (XIP) operation through continuous read modes with wrap capabilities.
