MT46V32M16P-5B:F TR

The MT46V32M16P-5B:F TR is a 512 Mbit DDR SDRAM device organized as 32M × 16 with a parallel memory interface in a 66-pin TSSOP package. It implements a double-data-rate architecture with source-synchronous DQS signaling and an internal DLL to enable two data transfers per clock cycle.

This device is suited for systems and modules that require a 512 Mbit parallel DDR memory solution with 2.5V I/O, programmable burst lengths, and commercial-temperature operation. Key value propositions include DDR data throughput at a 200 MHz clock rate, compact 66-TSSOP packaging, and industry-standard SSTL_2-compatible I/O levels.

Key Features

• Core architecture Internal pipelined DDR architecture with two data accesses per clock cycle and an on-chip DLL for DQ/DQS alignment.
• Memory organization 512 Mbit capacity organized as 32M × 16 with four internal banks for concurrent operation.
• Performance & timing Rated for a 200 MHz clock frequency (speed grade -5B), access window 700 ps, and programmable burst lengths of 2, 4, or 8.
• Data capture and masking Bidirectional data strobe (DQS) transmitted/received with data; x16 device includes two DQS signals and two data mask (DM) inputs—one per byte.
• Interface & clocking Parallel memory interface with differential clock inputs (CK/CK#) and commands entered on each positive CK edge.
• Refresh and self-refresh Auto refresh with 8K refresh cycles (64 ms, 8192 cycles for commercial devices); self-refresh option noted in datasheet where applicable.
• Power & I/O Operating VDD/VDDQ reported in the datasheet at nominal 2.5 V (spec range 2.5 V – 2.7 V); 2.5 V I/O compatible with SSTL_2 signaling.
• Package & temperature 66-pin TSSOP (0.400", 10.16 mm width) package; commercial operating temperature 0 °C to +70 °C (TA).
• Write timing Write cycle time (word page) specified at 15 ns.

Typical Applications

• Parallel DDR memory subsystems — Provides 512 Mbit, x16 parallel DDR storage for systems that require compact TSSOP packaging and SSTL_2 I/O.
• High-bandwidth buffering — Used as DRAM buffer memory where double-data-rate transfers and programmable burst lengths improve throughput.
• Embedded module memory — Suited for embedded designs needing a 32M × 16 memory organization in a 66-pin footprint and commercial temperature range.

Unique Advantages

• DDR data throughput: The double-data-rate architecture delivers two data transfers per clock cycle, enabling higher effective bandwidth at a given clock frequency.
• Compact TSOP packaging: The 66-TSSOP package (10.16 mm width) provides a space-efficient form factor for board-level integration.
• Source-synchronous capture: Bidirectional DQS and an internal DLL support reliable data capture and alignment with the clock.
• SSTL_2-compatible I/O: 2.5 V I/O levels align with common SSTL_2 signaling standards for memory interfaces.
• Programmable bursts and multi-bank operation: Burst length options (2, 4, 8) and four internal banks allow flexible data transfer patterns and concurrent operations.
• Commercial-grade operating range: Specified for 0 °C to +70 °C (TA) to match commercial temperature environments.
