MT46V32M16P-5B AIT:J

The MT46V32M16P-5B AIT:J is a 512 Mbit DDR SDRAM organized as 32M × 16 with a parallel memory interface in a 66‑TSSOP package. It implements a double-data-rate architecture with source‑synchronous data strobes for high-throughput memory access in embedded and automotive-capable designs.

Targeted use cases include systems requiring compact, high-speed volatile memory with automotive-grade qualification and a narrow TSOP footprint where board-level reliability and deterministic timing are important.

Key Features

• Core / Architecture  Internal pipelined DDR architecture enables two data accesses per clock cycle and supports four internal banks for concurrent operation.
• Memory Organization  512 Mbit capacity organized as 32M × 16 bits, with parallel interface and two data bytes (x16) for byte-oriented operations.
• Performance  Speed grade -5B supports a clock frequency up to 200 MHz with an access time of 700 ps and a write cycle time (word page) of 15 ns.
• Data timing and capture  Bidirectional data strobe (DQS) is transmitted/received with data (x16 has two DQS signals, one per byte); DLL aligns DQ/DQS with CK for source-synchronous capture. Differential clock inputs (CK/CK#) and programmable burst lengths (2, 4, 8) are supported.
• Power and I/O  Operating supply range is 2.5 V–2.7 V with 2.5 V I/O (SSTL_2 compatible) and VDD/VDDQ operating points indicated in the datasheet.
• System reliability and refresh  Auto refresh supported with 8K refresh cycles; device includes data mask (DM) functionality (x16 has two DM signals) and concurrent auto-precharge options.
• Automotive Qualification  AEC‑Q100 qualification and an automotive grade designation are provided for designs requiring automotive-capable components.
• Package  66‑TSSOP (0.400", 10.16 mm width) longer‑lead TSOP option for improved board-level reliability and mechanical robustness.
• Operating Range  Specified operating ambient temperature: −40 °C to +85 °C (TA).

Typical Applications

• Automotive electronic modules  Use as volatile working memory in automotive control units where AEC‑Q100 qualification and a compact TSOP footprint are required.
• Embedded systems  High-throughput DDR memory for microcontroller- or SoC‑based platforms needing parallel DDR storage and deterministic timing.
• Industrial control  Local DRAM for data buffering and real‑time processing in industrial electronics operating across wide temperature ranges.

Unique Advantages

• DDR performance with predictable timing: Double‑data‑rate architecture and DLL alignment provide consistent source‑synchronous data capture and support up to 200 MHz clocking for burst transfers.
• Automotive-capable qualification: AEC‑Q100 qualification and automotive grade designation support use in designs that require industry-recognized component screening.
• Compact, reliable package: 66‑TSSOP longer‑lead package offers a narrow board footprint with improved lead length for mechanical reliability.
• Byte-level control: Two DQS and two DM signals on x16 configuration enable byte-oriented masking and timing control for flexible system integration.
• Flexible refresh and power: Auto refresh with 8K cycle support and a 2.5 V I/O supply simplify interfacing with SSTL_2-compatible memory controllers.
