MX29LV320ETXEI-70G

Product Overview

The MX29LV320ETXEI-70G from Macronix is a non-volatile NOR flash memory IC that provides 32Mbit of storage in a 4M x 8 organization. The device uses a parallel memory interface and is housed in a 48-LFBGA, CSP (6x8) surface-mount package. It operates from a 2.7V to 3.6V supply and over an ambient temperature range of -40°C to 85°C. The 70 ns access time and 70 ns word/page write cycle time define its timing envelope for parallel bus designs.

Key Features

• 32Mbit non-volatile NOR flash memory with 4M x 8 organization.
• Parallel memory interface for connection to systems with a parallel bus.
• 70 ns access time and 70 ns word/page write cycle time.
• 2.7V to 3.6V supply voltage range.
• Operating ambient temperature range of -40°C to 85°C.
• 48-LFBGA, CSP (6x8) surface-mount package.

Applications

• Embedded systems that require non-volatile storage for configuration data.
• Low-voltage devices operating from a 2.7V to 3.6V supply.
• Parallel-bus memory expansion in designs using a 48-LFBGA surface-mount package.
• Systems that need operation across an extended ambient temperature range of -40°C to 85°C.

Design & Procurement Notes

When selecting the MX29LV320ETXEI-70G, confirm that the host controller supports a parallel memory interface and that the 4M x 8 organization matches the address and data mapping in the design. The 70 ns access and word/page write cycle times should be checked against the system bus timing budget, especially for 2.7V to 3.6V operation. Layout planning should account for the 48-LFBGA, CSP (6x8) surface-mount package and the -40°C to 85°C ambient operating range. Because this is a non-volatile NOR flash device, design reviews should consider how read and write operations fit the application memory architecture.
