MX29GL320EHT2I-70G

Product Overview

The MX29GL320EHT2I-70G from Macronix is a 32Mbit non-volatile FLASH memory device using NOR technology and a parallel interface. The 4M x 8 memory organization defines the address and data structure of the array, and the 70 ns access time supports read operations in systems that use a parallel memory bus. The device operates from a 2.7 V to 3.6 V supply and is specified for an ambient temperature range of -40°C to 85°C. It uses a surface-mount 56-TSOP package.

Key Features

• 32Mbit non-volatile NOR FLASH memory with 4M x 8 organization
• Parallel memory interface with 70 ns access time
• 70 ns write cycle time for word/page operations
• 2.7 V to 3.6 V supply voltage range
• -40°C to 85°C ambient operating temperature range
• Surface-mount 56-TSOP package with 0.724 in (18.40 mm) width
• Part of the Macronix MX29GL series

Applications

• Embedded controller firmware storage
• Boot code storage in networking equipment
• Non-volatile data logging modules
• Program and data storage in consumer electronics

Design & Procurement Notes

When selecting this memory for a design, confirm that the host controller supports a parallel NOR flash interface and can meet the timing requirements associated with the 70 ns access and word/page write cycle time. The 4M x 8 organization determines address and data bus usage, so board routing, signal integrity, and address mapping should be planned around the 32Mbit capacity. The 2.7 V to 3.6 V supply range and -40°C to 85°C ambient operating range should be checked against the system power and thermal environment. The surface-mount 56-TSOP footprint, with a 0.724 in (18.40 mm) width, affects PCB layout and reflow processing. Procurement should verify the exact package code and mechanical footprint to avoid mismatches during board assembly.
