The MT46V32M16BN-6IT is a 512Mb DDR SDRAM component from Micron Technology. It is designed for use in applications that require a high memory capacity and fast data transfer rates. The device is organized as 32Mb x 16, meaning it has a 32 Megabit memory density with a 16-bit data bus. The -6 indicates the speed grade, likely operating around 166MHz DDR, and the IT designates the industrial temperature range.

Applications

• Industrial control systems
• Networking equipment
• Embedded systems
• Automotive applications
• Harsh environment applications

Features

• Double Data Rate (DDR) Architecture: Doubles the memory bandwidth by transferring data on both the rising and falling edges of the clock signal.
• 32Mb x 16 Organization: Provides a 512Mb memory capacity with a 16-bit data bus.
• Differential Clock Inputs (CK and /CK): Provides enhanced noise immunity.
• Data Mask (DM): Allows selective data masking for write operations.
• Auto Refresh Mode: Automatically refreshes memory contents.
• Self Refresh Mode: Allows the device to maintain data in a low-power state.
• Programmable Burst Length: Allows flexible data transfer.
• Programmable CAS Latency (CL): Allows adjustable read latency.

Benefits

• High bandwidth: DDR architecture provides high memory bandwidth.
• Large memory capacity: 512Mb provides ample memory space.
• Low power consumption: Auto and Self Refresh modes minimize power use.
• Robust performance: Industrial temperature range ensures reliable operation in harsh environments.
• Flexibility: Programmable features allow for optimization for different applications.

Additional Details

The MT46V32M16BN-6IT is typically supplied in a BGA (Ball Grid Array) package for surface mount assembly. It usually operates at 2.5V. Proper PCB design is crucial to achieving optimal performance, including impedance matching, termination, and decoupling capacitors placed near the power pins. The industrial temperature range (-40°C to +85°C) ensures reliability in demanding conditions. The component may be RoHS compliant, indicated by the lack of a lead (Pb) symbol in the part number details.
