MX25L2026EM1I-12G

Memory IC Overview

The MX25L2026EM1I-12G is a 2-Mbit CMOS Serial Flash memory device manufactured by Macronix. It features a Serial Peripheral Interface (SPI) compatible with Mode 0 and Mode 3, supporting a maximum serial clock frequency of 86 MHz for standard read operations and 80 MHz in Dual Output mode. The device operates on a single power supply ranging from 2.7 V to 3.6 V. It offers a memory organization of 2,097,152 x 1 bit or 1,048,576 x 2 bits, structured into 64 equal sectors of 4 Kbytes each and 4 equal blocks of 64 Kbytes each. The component is housed in an 8-pin SOP package.

Memory IC Feature Summary

• Supports Dual Output read mode for enhanced data throughput using two I/O pins.
• Includes hardware and software protection mechanisms via WP# pin and status register bits to prevent inadvertent erasure or programming.
• Features a Hold function that pauses serial communications without deselecting the device.
• Provides electronic identification capabilities through JEDEC Device ID and Electronic Signature commands.

Memory IC Applications

• Firmware storage in embedded systems
• Code execution in XIP (Execute-In-Place) applications
• Data logging in industrial control devices

Memory IC Procurement Notes

Verify the specific suffix EM1I-12G against the manufacturer's current ordering guide to confirm package type and temperature range. Ensure compatibility with system voltage levels within the 2.7V to 3.6V operating window. Check for RoHS compliance requirements if applicable to your manufacturing process. Confirm lead times as availability may vary by distributor.

Memory IC Selection Notes

Select this component when a small capacity NOR flash with SPI interface is required for code storage. It is suitable for applications needing moderate speed access up to 86 MHz. Consider the 8-pin SOP package constraints for PCB layout. Evaluate the need for dual output mode if higher read speeds are necessary compared to standard SPI.

Memory IC Part Context

This part belongs to the MX25L series of 3V Serial Flash memories from Macronix. The series is designed for general-purpose non-volatile storage with low power consumption. It shares common command sets and interface protocols with other members of the MX25L family, facilitating design reuse across different memory densities.

Memory IC FAQ

What is the difference between Standard Read and Dual Output Read modes?

Standard Read uses one I/O pin (SO) for data output at up to 86 MHz. Dual Output Read uses both SI and SO pins (SIO0 and SIO1) for data output, allowing faster transfer rates at a maximum clock frequency of 80 MHz.

How does the Hold feature work?

The Hold feature allows the user to pause serial communication without deasserting Chip Select (CS#). It is activated by pulling the HOLD# pin low while SCLK is low. Data output goes high-impedance during hold, and communication resumes when HOLD# goes high.
