MX25V4006EM1I-13G

Memory IC Overview

The MX25V4006EM1I-13G is a 4-Mbit CMOS Serial Flash Memory from Macronix, operating on a single 2.35V to 3.6V supply. It features a 4-wire SPI interface supporting Mode 0 and Mode 3 with a maximum clock frequency of 75MHz. The memory organization consists of 128 equal sectors (4KB each) and 8 equal blocks (64KB each). It supports Dual Output mode at up to 70MHz. Key electrical parameters include a maximum active read current of 12mA at 75MHz and a standby current of 15µA. The device operates within a temperature range of -40°C to +85°C and is housed in an 8-pin SOP package.

Memory IC Feature Summary

• Supports standard SPI Mode 0 and Mode 3 along with Dual Output read mode for increased throughput.
• Includes hardware and software protection mechanisms via WP# pin and status register bits to prevent inadvertent writes.
• Features a HOLD function that pauses serial communication without deselecting the chip.
• Integrates auto erase and auto program algorithms that handle internal timing and verification.

Memory IC Applications

• Storage of firmware and boot code in embedded systems
• Data logging applications requiring non-volatile storage
• Configuration data storage in consumer electronics

Memory IC Procurement Notes

Verify the specific suffix '13G' against the manufacturer's ordering guide to confirm the package type and tape/reel specifications. Ensure the voltage range matches the system design requirements. Check for RoHS compliance documentation if required by local regulations. Confirm availability of the 8-pin SOP variant as other packages exist within the same series.

Memory IC Selection Notes

Select this component when a 4Mbit capacity is sufficient and low power consumption is critical. The 2.35V minimum voltage makes it suitable for 2.5V systems. Consider the 75MHz speed limit for high-performance interfaces. Verify that the 8-pin SOP footprint fits the PCB layout constraints compared to smaller packages like USON or WSON available in the same family.

Memory IC Part Context

This part belongs to the MX25V series of 2.5V Serial NOR Flash memories. It shares architectural similarities with the MX25L series but differs in operating voltage ranges. The MX25V4006E datasheet defines the core functionality, while the '13G' suffix typically denotes the specific package and shipping configuration provided by Macronix.

Memory IC FAQ

How does the HOLD feature affect ongoing operations?

The HOLD feature pauses serial communications when the HOLD# pin goes low. It does not stop in-progress write status register, programming, or erasing operations. Communication resumes when HOLD# goes high while SCLK is low.

What is the difference between Mode 0 and Mode 3 SPI support?

Both modes are supported. The difference lies in the clock polarity (CPOL) and phase (CPHA). Mode 0 uses CPOL=0 and CPHA=0, while Mode 3 uses CPOL=1 and CPHA=1, affecting when data is sampled relative to the clock edge.
