MT46V32M16CY-5B AIT:J

Memory IC Overview

The MT46V32M16CY-5B AIT:J is a 512Mb DDR SDRAM organized as 8 Meg x 16 with four internal banks. It operates at a maximum clock frequency of 200 MHz (DDR400) with a cycle time of 5ns and CAS latency of 3. The device uses a 60-ball FBGA package, supports 2.5V ±0.2V power supply, and functions within an industrial temperature range of -40°C to +85°C.

Memory IC Feature Summary

• Double data rate architecture enabling two data accesses per clock cycle via pipelined design.
• Source-synchronous data capture using bidirectional data strobes (DQS) for improved timing alignment.
• Four internal banks allowing concurrent operations to maximize effective bandwidth.
• SSTL_2 compatible I/O interface supporting programmable burst lengths and auto precharge.

Memory IC Applications

• High-performance computing systems requiring fast memory access.
• Graphics applications utilizing high-bandwidth video memory.
• Industrial embedded systems operating in extended temperature environments.

Memory IC Procurement Notes

Verify component authenticity through official Micron channels or authorized distributors. Confirm the specific suffix IT:J matches industrial temperature ratings and lead-free packaging requirements. Check current lifecycle status as older DDR generations may be discontinued or subject to obsolescence notices.

Memory IC Selection Notes

Select this part for designs requiring 16-bit data width and 200MHz operation speeds. Ensure the system supports differential clock inputs and SSTL_2 signaling standards. Verify that the PCB layout accommodates the 60-ball FBGA package dimensions and thermal requirements for industrial grade operation.

Memory IC Part Context

This component belongs to the Micron MT46V series of 512Mb DDR SDRAMs. It shares architectural features with other variants in the family, differing primarily in organization, speed grade, and package type. The CY designation indicates a specific manufacturing revision within the Core DDR Rev. B specification.

Memory IC Replacement Considerations

Direct replacements include other Micron MT46V32M16 variants with compatible speed grades such as -6T or -75, provided timing constraints are met. Cross-manufacturer equivalents require careful verification of pinouts, voltage levels, and command sets.
