MX25L6433FM2I-08Q

Memory IC Overview

The MX25L6433FM2I-08Q is a 64 Mbit Serial NOR Flash memory device manufactured by Macronix. It operates within a voltage range of 2.65 V to 3.6 V and supports synchronous SPI interfaces with clock frequencies up to 133 MHz. The memory organization is specified as 16 M x 4, utilizing a Quad I/O data bus width. The component is housed in an SOP-8 package with a maximum active read current of 17 mA. It is designed for industrial temperature ranges, functioning between -40°C and +85°C.

Memory IC Feature Summary

• Supports Single, Dual, and Quad I/O modes via the MXSMIO interface for flexible data transfer rates.
• Includes hold feature to pause operations without losing program or erase state.
• Features auto erase and auto program algorithms to simplify command sequences.

Memory IC Applications

• Industrial control systems requiring reliable code storage
• Automotive electronics operating in extended temperature environments
• IoT devices needing non-volatile firmware retention

Memory IC Procurement Notes

Verify the specific suffix 'I' against official datasheets to confirm the industrial temperature grade (-40°C to +85°C) versus commercial variants. Ensure the SOP-8 package dimensions match your PCB footprint requirements. Confirm RoHS compliance status through the manufacturer's latest documentation before finalizing procurement specifications.

Memory IC Selection Notes

Select this component when a 64 Mbit capacity is required with high-speed Quad I/O access. It is suitable for applications demanding operation at voltages as low as 2.65 V. Consider the SOP-8 package size constraints and the 133 MHz maximum clock frequency relative to system timing requirements.
