MT46V16M16CY-5B AAT:M

The MT46V16M16CY-5B AAT:M is a 256 Mbit DDR SDRAM organized as 16M × 16 with a parallel memory interface in a 60-ball FBGA package. It implements an internal, pipelined double-data-rate architecture with source-synchronous data capture and is available in an automotive temperature grade with AEC-Q100 qualification.

Designed for systems that require compact, high-speed volatile memory, this device offers a 200 MHz clock rating, a 700 ps access time, and a supply range of 2.5 V to 2.7 V, making it suitable for high-reliability environments and temperature ranges from −40°C to 105°C.

Key Features

• Core / Architecture Internal pipelined DDR architecture enabling two data accesses per clock cycle; differential clock inputs (CK/CK#) and DLL alignment of DQ/DQS with CK.
• Memory Organization & Capacity 256 Mbit capacity organized as 16M × 16 with four internal banks for concurrent operation.
• Data I/O and Strobe Bidirectional data strobe (DQS) transmitted/received with data for source-synchronous capture; x16 devices provide two DQS signals (one per byte) and two data mask (DM) signals.
• Performance / Timing Speed grade -5B with a 5 ns cycle time (CL = 3) supporting a 200 MHz clock rate; specified access time of 700 ps and a word-page write cycle time of 15 ns.
• Power VDD and VDDQ supply range from 2.5 V to 2.7 V (with DDR400-specific VDD/VDDQ options noted in datasheet); I/O standard compatible with 2.5 V SSTL_2 signaling.
• Refresh and Self-Management Supports auto refresh (64 ms/8192-cycle and 16 ms/8192-cycle modes shown in datasheet). Note: self-refresh is not available on AAT (automotive) devices.
• Qualification & Reliability AEC-Q100 qualified and offered in an automotive temperature grade (−40°C to +105°C) with PPAP submission and 8D response capability listed in the datasheet.
• Package 60-ball TFBGA (8 mm × 12.5 mm) package (60-FBGA footprint) suitable for surface-mount assembly in space-constrained designs.

Typical Applications

• Automotive electronic systems Use as volatile DDR working memory in automotive platforms requiring AEC-Q100 qualification and operation from −40°C to +105°C.
• High-temperature embedded systems Provides compact DDR memory where operation across extended temperature ranges and automotive-grade qualification are required.
• High-speed parallel buffering Serves as high-speed buffering or working memory for systems utilizing a parallel DDR interface with source-synchronous DQS signaling.

Unique Advantages

• Automotive-grade qualification: AEC-Q100 qualification and an AAT temperature rating (−40°C to +105°C) support deployment in automotive and harsh-environment designs.
• Source-synchronous data capture: Bidirectional DQS and DLL alignment improve data timing margins for reliable high-speed DDR transfers.
• Compact FBGA footprint: 60-ball FBGA (8 mm × 12.5 mm) package minimizes board area while providing the required I/O for x16 operation.
• Deterministic timing: Speed grade -5B with 5 ns cycle time (CL = 3) and a 200 MHz clock rating supports predictable DDR timing characteristics.
• Design-level robustness: Four internal banks, programmable burst lengths (BL = 2, 4, 8), and auto-refresh options provide flexibility for concurrent operation and memory management strategies.
