MT46V32M16CY-5B AIT:J TR

The MT46V32M16CY-5B AIT:J TR is a 512 Mbit DDR (Double Data Rate) SDRAM organized as 32M × 16 with a parallel memory interface. It implements an internal pipelined DDR architecture with source-synchronous DQS and a DLL to align data transitions, delivering two data transfers per clock cycle.

Designed and qualified for demanding use, the device supports a 200 MHz clock rate (–5B speed grade), operates from 2.5 V to 2.7 V, and carries AEC-Q100 qualification with an operating temperature range of –40°C to +85°C (TA).

Key Features

• Core / Architecture  Internal pipelined DDR architecture supporting two data accesses per clock cycle, differential clock inputs (CK/CK#), and an on-die DLL for DQ/DQS alignment.
• Memory Organization  512 Mbit capacity organized as 32M × 16 with four internal banks and data mask (DM) support (x16 has two DMs — one per byte).
• Performance & Timing  200 MHz clock frequency for the –5B speed grade (DDR400B timing option); access window and data-out timing designed for CL = 3 with a 1.6 ns data-out window and an access time on the order of 700 ps.
• Power  VDD / VDDQ supply range supported at 2.5 V ±0.2 V (documented product range 2.5 V to 2.7 V), with SSTL_2-compatible 2.5 V I/O.
• Refresh & Control  Auto refresh with an 8K refresh count and programmable burst lengths of 2, 4, or 8; concurrent auto precharge and standard DDR command set behavior.
• Signal Timing & Capture  Bidirectional data strobe (DQS) transmitted/received with data (edge-aligned for READs, center-aligned for WRITEs) to enable source-synchronous data capture.
• Reliability & Qualification  AEC-Q100 qualification and an operating temperature range of –40°C to +85°C (TA) for automotive/industrial applications requiring qualified components.
• Package  60-ball TFBGA / FBGA package (60-FBGA, 8 × 12.5 mm footprint) for compact board-level integration.

Typical Applications

• Automotive Electronics  Automotive-grade DDR memory for systems requiring AEC-Q100-qualified volatile DRAM modules within the device temperature range.
• Embedded Systems  Parallel DDR memory for embedded controllers and modules that need a 16-bit data path and standard DDR features (burst access, auto refresh).
• Industrial Control  Memory subsystem in industrial applications that require AEC-Q100 qualification and operation over –40°C to +85°C ambient.
• Memory Subsystems  Integration into boards and modules that use a parallel DDR interface and compact 60-ball FBGA packaging.

Unique Advantages

• AEC-Q100 Qualified:  Delivered with AEC-Q100 qualification to address reliability needs in automotive and harsh-environment applications.
• DDR Performance at 200 MHz:  –5B speed grade supports a 200 MHz clock rate with CL = 3 timing, enabling double-data-rate throughput with a documented data-out window.
• Robust DDR Feature Set:  Built-in DLL, DQS source-synchronous capture, programmable burst lengths, and concurrent auto precharge simplify high-speed memory design and timing closure.
• Compact, Board-Friendly Package:  60-ball FBGA (8 × 12.5 mm) provides a small footprint for space-constrained PCBs while supporting a 16-bit data interface.
• Wide Supply Range:  Operates across a 2.5 V to 2.7 V supply window compatible with 2.5 V I/O signaling standards.
• Standard Refresh Behavior:  8K refresh count and auto-refresh support help maintain data integrity with standard DDR refresh mechanisms.

Why Choose IC DRAM 512MBIT PARALLEL 60FBGA?

The MT46V32M16CY-5B AIT:J TR positions itself as a compact, automotive‑qualified DDR SDRAM device combining standard DDR feature sets (DLL, DQS, programmable bursts) with a 16-bit organization and a 60-ball FBGA footprint. Its –5B speed grade and 200 MHz clock capability deliver double-data-rate throughput while operating from a 2.5–2.7 V supply.

This device is well suited to designs that require a qualified, board-level DDR memory building block—particularly where AEC-Q100 qualification, a wide operating temperature range (–40°C to +85°C TA), and compact packaging are priorities for long-term robustness and predictable integration.
