BY25Q32CSTJG(T)

Memory IC Overview

The BY25Q32CSTJG(T) is a 32M-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. Key electrical parameters include a maximum active current of 20mA and a maximum power-down current of 5uA. It features flexible architecture with 4K-byte sectors and 32/64K-byte blocks.

Memory IC Feature Summary

• Supports multiple interface modes including Standard SPI, Dual SPI, Quad SPI, and QPI for versatile system integration.
• Provides comprehensive write protection mechanisms via software configuration, hardware /WP pin control, and three 256-byte security registers with OTP locks.
• Features flexible memory architecture allowing sector, half-block, block, or full chip erase operations with suspend and resume capabilities.

Memory IC Applications

• Embedded systems requiring non-volatile code storage
• Industrial control devices needing reliable data retention
• Consumer electronics utilizing firmware updates

Memory IC Procurement Notes

Verify the specific suffix 'TJG' against official ordering information to confirm package type and temperature grade. Ensure compatibility with host voltage levels within the 2.7V to 3.6V range. Confirm moisture sensitivity handling requirements during assembly. Cross-reference JEDEC IDs if migrating from other manufacturers.

Memory IC Selection Notes

Select this component when a 32M-bit capacity is required with support for high-speed Quad I/O and QPI modes. Consider the industrial temperature range options (-40°C to +85°C or +105°C) based on environmental conditions. Evaluate the need for hardware write protection and security register features for application-specific data integrity requirements.
