MT46V16M16FG-5B:F TR

The MT46V16M16FG-5B:F TR is a 256 Mbit DDR SDRAM organized as 16M × 16 with a parallel memory interface in a 60-ball FBGA (8 × 14 mm) package. It implements a double-data-rate internal pipelined architecture with two data accesses per clock cycle and is targeted at systems that require commodity parallel DDR memory for board-level integration.

This device operates at a 200 MHz clock frequency (speed grade -5B), supports VDD/VDDQ in the 2.5 V to 2.7 V range, and is specified for commercial temperature operation from 0 °C to 70 °C.

Key Features

• Core architecture  Internal pipelined DDR architecture providing two data transfers per clock cycle and a DLL to align DQ/DQS transitions with CK.
• Memory organization  256 Mbit capacity arranged as 16M × 16 with four internal banks for concurrent operation.
• Performance / Timing  Rated for a 200 MHz clock (speed grade -5B) with an access time of 700 ps and a word-page write cycle time of 15 ns. Table timing for -5B includes a data-out window of 1.6 ns and DQS‑DQ skew of +0.40 ns.
• Interface  Parallel DDR interface with bidirectional data strobe (DQS) transmitted/received with data and differential clock inputs (CK/CK#).
• Power  VDD and VDDQ supported at +2.5 V ±0.2 V (also noted for DDR400 variant VDD = +2.6 V ±0.1 V in datasheet options); I/O compatible with 2.5 V (SSTL_2-compatible).
• Programmability and refresh  Supports programmable burst lengths (2, 4, or 8), auto-refresh (8K refresh cycles), and self-refresh options as documented in the datasheet.
• Package and mounting  60-ball FBGA package (8 mm × 14 mm) optimized for board mounting in compact system designs.
• Operating conditions  Commercial temperature rating: 0 °C to +70 °C as specified in the product data.

Typical Applications

• Embedded systems  Provides parallel DDR memory for embedded control and processing modules that require discrete DRAM integration.
• Consumer electronics  Suitable for consumer devices that need off-chip parallel DDR memory in a compact FBGA footprint.
• Networking and communications modules  Supports buffering and temporary data storage in board-level network interface and communication modules using a parallel DDR interface.

Unique Advantages

• DDR internal architecture: Enables two data accesses per clock cycle, increasing effective data throughput versus single-data-rate DRAM.
• Byte-aligned strobes: Bidirectional DQS (two DQS signals for x16) provides source-synchronous data capture and improved timing alignment.
• Compact FBGA package: 60-ball FBGA (8×14 mm) offers a small board footprint for dense system layouts.
• Verified timing grade -5B: Rated at 200 MHz with specified data-out and access windows, allowing predictable timing design trade-offs.
• Standard supply voltages: Operates on industry-standard 2.5 V I/O and VDD/VDDQ ranges, simplifying power-rail design.
