MT46V32M16BN-6:F TR

The MT46V32M16BN-6:F TR is a 512 Mbit DDR SDRAM device from Micron, organized as 32M × 16 with a parallel memory interface. It implements an internal, pipelined double-data-rate architecture with source-synchronous data capture to deliver two data accesses per clock cycle.

Designed for systems that require compact 512 Mbit DDR memory in a 60-ball FBGA package, the device balances performance (167 MHz clock grade) and integration with a 10 × 12.5 mm footprint and standard 2.5 V I/O signaling.

Key Features

• Core Architecture Internal, pipelined DDR SDRAM providing two data accesses per clock cycle, with a DLL to align DQ/DQS transitions with CK.
• Memory Organization 512 Mbit capacity arranged as 32M × 16 with four internal banks to support concurrent operation.
• Interface and Timing Parallel DDR interface with differential clock inputs (CK/CK#), bidirectional DQS (x16 devices include two DQS signals, one per byte), and commands registered on positive CK edges.
• Performance Speed grade supports a 167 MHz clock frequency (DDR333 timing grade), with an example access time of 700 ps and programmable burst lengths of 2, 4, or 8.
• Power Standard 2.5 V I/O (SSTL_2 compatible); supply range listed as 2.3 V to 2.7 V in device specifications.
• Refresh and Power Management Auto refresh with commercial specification of 64 ms/8192 cycles and support for self-refresh (self-refresh noted as not available on AT devices in the datasheet).
• Package 60-ball TFBGA (10 mm × 12.5 mm) package (60-FBGA, Pb-free BN option) for compact board-level integration.
• Operating Range Commercial temperature rating with an operating ambient of 0°C to +70°C.
• Write/Access Timing Write cycle time (word page) specified at 15 ns and timing grade -6 compatible with CL = 2.5 operation at 167 MHz.

Typical Applications

• PC and computing memory subsystems Suitable for designs targeting DDR memory speed grades shown in the datasheet (examples include PC3200/PC2700/PC2100 compatibility listings).
• Embedded memory subsystems Compact 60-ball FBGA package and 512 Mbit density make it appropriate for board-level integration where a parallel DDR SDRAM is required.
• SSTL_2-compatible I/O systems 2.5 V I/O signaling supports integration into systems designed around SSTL_2 electrical interfaces.

Unique Advantages

• DDR performance architecture: Pipelined DDR design with source-synchronous DQS capture delivers two data transfers per clock cycle for increased throughput.
• Byte-level data strobes and masking: Bidirectional DQS signals and data mask (DM) support (x16 includes two DQS/DM) simplify timing and write masking at the byte level.
• Flexible burst operation: Programmable burst lengths of 2, 4, or 8 enable tuning for different access patterns and throughput requirements.
• Compact package footprint: 60-ball FBGA (10 × 12.5 mm) enables high-density board layouts while maintaining standard BGA assembly practices.
• Commercial grade timing options: -6 timing grade provides 167 MHz operation with well-defined timing windows and access parameters from the datasheet.
• Standardized I/O signaling: 2.5 V I/O (SSTL_2 compatible) simplifies interface design with common memory controller standards.
