MX25L12855FXCI-10G

Memory IC Overview

The MX25L12855FXCI-10G is a 128Mb (16M x 8) CMOS Serial Multi I/O Flash Memory manufactured by Macronix. It operates on a single power supply ranging from 2.7V to 3.6V for read, erase, and program operations. The device supports SPI Mode 0 and Mode 3 with fast read capabilities reaching up to 133MHz across all protocols. It features Quad Peripheral Interface (QPI), advanced security including block lock and secured OTP, and a 256-byte page buffer.

Memory IC Feature Summary

• Supports Single, Dual, and Quad I/O protocols with configurable dummy cycles for optimized data throughput.
• Includes advanced security features such as hardware write protection via WP#, software block lock, and a factory or customer-lockable 4K-bit secured OTP.
• Features a 256-byte page buffer and quad input/output page programming to enhance write performance.
• Provides Program/Erase suspend and resume functionality to allow non-volatile code execution during memory operations.

Memory IC Applications

• Firmware storage in embedded systems requiring direct code execution.
• Data logging applications utilizing the secured OTP for unique identifiers.
• Industrial control systems needing robust hardware and software write protection mechanisms.

Memory IC Procurement Notes

Verify the specific suffix 'XCI' against official Macronix documentation to confirm package type and temperature range. Ensure compatibility with host controller SPI modes. Confirm RoHS compliance status if required by assembly specifications. Check for lead-free manufacturing standards.

Memory IC Selection Notes

Select this component when high-speed read access up to 133MHz is required alongside flexible I/O configurations. Consider its advanced security features for applications demanding strict data integrity and anti-tampering measures. Evaluate the 128Mb capacity against system memory requirements to ensure sufficient space for firmware and configuration data.
