MX25V20066M1I02

Memory IC Overview

The MX25V20066 is a 2M-bit CMOS Serial NOR Flash memory featuring Macronix's proprietary MXSMIO technology. It operates on a single power supply ranging from 2.3V to 3.6V for read, erase, and program functions. The device supports Serial Peripheral Interface (SPI) Mode 0 and Mode 3, offering high-performance fast read capabilities at up to 80MHz with 8 dummy cycles in both Single I/O and Dual I/O modes. Memory organization includes equal sectors of 4K bytes and blocks of 32K or 64K bytes, allowing flexible individual block erasure.

Memory IC Feature Summary

• Supports Single I/O and Dual I/O read modes via Serial Peripheral Interface
• Provides advanced security through software and hardware block lock protection
• Features auto erase and auto program algorithms with internal timing control
• Includes status register monitoring for write-in-progress detection

Memory IC Applications

• Code storage in embedded systems requiring sequential read operations
• Data logging applications needing reliable sector-level erasure
• Firmware storage in consumer electronics operating within specified voltage ranges
• Industrial control systems utilizing hardware write protection features

Memory IC Procurement Notes

Verify the specific package variant required, as the MX25V20066 is available in 8-pin SOP (150mil), 8-pin SOP (200mil), and 8-land USON (2x3mm). Confirm that the design supports the 2.3V to 3.6V operating range. Ensure compatibility with SPI Mode 0 and Mode 3 protocols. Check for RoHS compliance and halogen-free status if required by environmental standards. Validate pin configurations against the selected package type during schematic capture.

Memory IC Selection Notes

Select this component when a 2M-bit capacity is sufficient for application requirements. Choose based on the necessary package style, such as SOP or USON, depending on board space constraints. Consider the Dual I/O mode if higher data throughput is needed without increasing clock frequency. Ensure the system provides adequate voltage stability within the 2.3V to 3.6V window. Evaluate the need for hardware write protection via the WP# pin if security is critical.

Memory IC Part Context

This device belongs to the MX25V series of Serial NOR Flash memories from Macronix. It utilizes CMOS technology and MXSMIO architecture to balance performance and power consumption. The series is designed for general-purpose non-volatile storage needs in various electronic devices. It shares command set similarities with other Macronix serial flash parts but differs in density and specific electrical characteristics.

Memory IC Replacement Considerations

Direct substitutes must match the 2M-bit density, 2.3V-3.6V voltage range, and SPI interface. Verify pin compatibility for SOP-8 or USON packages. Check if alternative parts support Dual I/O modes if that feature is utilized. Ensure equivalent block protection mechanisms are present. Cross-reference JEDEC IDs if identification commands are used in the firmware.
