Memory IC datasheet and documents for BY25Q16ESTJG(T)
Memory IC Overview
The BY25Q16ESTJG(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. The device operates on a single 2.7V to 3.6V supply within -40°C to +85°C temperature range. Key electrical parameters include a 108MHz clock rate for Fast Read, 7ns access time, and 2M x 8 organization. Page program time is 0.16ms typical, sector erase is 20ms typical, and block erase is 0.055s/0.2s typical.
Memory IC Feature Summary
- Supports standard, dual, and quad SPI protocols along with QPI mode for high-speed data transfer.
- Enables Execute In Place (XIP) operation through continuous read modes with wrap capabilities.
- Includes flexible write protection via software commands and hardware /WP pin control.
- Features three 1024-byte security registers with One-Time Programmable (OTP) lock functionality.
Memory IC Applications
- Consumer electronics firmware storage
- Industrial control system code execution
- IoT device configuration and data logging
Memory IC Procurement Notes
Verify the specific suffix 'T' indicates tube packaging against official distributor listings. Confirm the 'E' designation aligns with the commercial temperature range (-40°C to +85°C). Ensure the ordering information matches the exact manufacturer part number to avoid compatibility issues with interface or voltage specifications.
Memory IC Selection Notes
Select this component when a 16M-bit capacity is required with a narrow 8-pin SOP footprint. It is suitable for applications needing XIP capability and high-speed Quad I/O transfers up to 432Mbits/s. Verify that the host system supports the required 2.7V-3.6V supply voltage and SPI command set.
Memory IC Part Context
This part belongs to the BY25Q16ES family of serial flash memories. It shares core architecture with other variants differing primarily in package type, temperature rating, and packing quantity. The 'STJG' suffix specifies the surface-mount SOP package and tube packaging format.
Memory IC Replacement Considerations
BY25Q16BSSJG(R) is listed as a parameter-equivalent substitute from the same manufacturer.
