MT46V32M8P-6T IT:G

The MT46V32M8P-6T IT:G is a 256Mbit Double Data Rate (DDR) SDRAM device organized as 32M × 8 with four internal banks. It implements a pipelined DDR architecture with bidirectional data strobe and differential clock inputs for source-synchronous data capture.

This device targets systems requiring a parallel DDR memory interface with 2.3V–2.7V supply operation and industrial temperature range, offering a balance of timing performance and board-level package options for integration into memory subsystems.

Key Features

• Core DDR Architecture Internal pipelined double-data-rate (DDR) operation enables two data accesses per clock cycle; differential clock inputs (CK/CK#) and a DLL align DQ/DQS transitions with CK.
• Memory Organization & Capacity 256 Mbit total capacity organized as 32M × 8 with four internal banks for concurrent operation.
• Performance & Timing Rated for 167 MHz operation (–6T timing grade / 6 ns cycle time, CL = 2.5) with an Access Time of 700 ps and a 2.0 ns data-out window at the 6T grade.
• Interface & Data Handling Parallel memory interface with bidirectional data strobe (DQS) transmitted/received with data, data mask (DM) for write masking, and programmable burst lengths (BL = 2, 4, or 8).
• Power Operates from a 2.3 V to 2.7 V supply range; supports VDD/VDDQ supply levels as specified for DDR operation and uses 2.5 V I/O signaling (SSTL_2-compatible).
• Refresh & Reliability Supports auto refresh with a 64 ms, 8192-cycle refresh interval for commercial and industrial devices.
• Package & Temperature Long-lead 66-TSSOP (0.400", 10.16 mm width) package; industrial operating temperature range –40°C to +85°C (TA).

Unique Advantages

• Double-data-rate throughput: Two data accesses per clock cycle increase effective bandwidth for parallel DDR memory architectures.
• Industry-standard I/O: 2.5 V SSTL_2-compatible I/O and DQS-based source-synchronous capture simplify timing alignment with common DDR host interfaces.
• Deterministic timing grade: The –6T timing grade supports 167 MHz operation with a defined data-out window, facilitating predictable timing design.
• Industrial temperature rating: –40°C to +85°C qualification supports deployments in temperature-variable environments.
• Compact board footprint: 66-TSSOP package provides a standardized, board-friendly form factor for surface-mount integration.
