MX25L12845GZNI-08G

Memory IC Overview

The MX25L12845GZNI-08G is a 128M-bit CMOS Serial NOR Flash memory from the MXSMIO series. It operates on a single 2.7V to 3.6V power supply and supports SPI Mode 0 and Mode 3 protocols including Single, Dual, and Quad I/O modes. The device features DTR (Double Transfer Rate) capability with clock frequencies up to 133MHz. It utilizes a 256-byte page buffer for programming and includes advanced security features such as block lock protection and a 4K-bit secured OTP area.

Memory IC Feature Summary

• Supports Single, Dual, and Quad I/O protocols with configurable dummy cycles for optimized read performance.
• Features hardware write protection via WP# pin and software-based block lock protection using BP bits.
• Includes a dedicated 4K-bit Secured OTP area for unique device identification that can be factory or customer locked.
• Provides program/erase suspend and resume functionality to allow non-intrusive read access during write operations.

Memory IC Applications

• Firmware storage in embedded systems requiring secure boot code execution.
• Data logging applications utilizing the secured OTP for unique serial number storage.
• Industrial control systems needing reliable code execution in place (XIP) capabilities.

Memory IC Procurement Notes

Verify the specific package variant matches the design requirements, as the ZNI suffix denotes an 8-land WSON package. Confirm voltage levels align with the 2.7V to 3.6V operational range. Ensure ESD handling procedures are followed due to the sensitivity of the CMOS technology. Cross-reference the revision history for any command set updates before finalizing the bill of materials.

Memory IC Selection Notes

Select this component when high-speed sequential read performance is required alongside robust data protection mechanisms. The inclusion of DTR mode makes it suitable for bandwidth-constrained interfaces demanding higher throughput without increasing clock frequency. Consider the 8-land WSON package if board space is limited compared to standard SOP options.

Memory IC Part Context

This part belongs to the Macronix MX25L12845G family, which offers 128M-bit capacity. The ZNI suffix specifically identifies the 8-land WSON (6x5mm) package configuration. It shares core electrical specifications and command sets with other variants in the MX25L12845G series, differing primarily in physical footprint and pinout arrangement.

Memory IC Replacement Considerations

Direct replacements must maintain the 128M-bit capacity, 3V operation, and WSON-8 package. Verify compatibility with existing firmware regarding command sets and timing parameters. Check for equivalent security feature support if OTP usage is critical to the application design.
