M14D2561616A-1.6BG2S

The M14D2561616A-1.6BG2S is a 256Mbit DDR2 SDRAM organized as 16M × 16, optimized for 1.8V commercial-class systems. It implements an internal pipelined double-data-rate architecture with differential clocks and SSTL_18 signaling to deliver DDR2-1200 (600MHz) operation for board-level memory integration.

Designed for applications that require a parallel DDR2 memory interface, this device offers selectable CAS latencies, on-die termination, and a compact 84-ball FBGA package suitable for high-density layouts.

Key Features

• Core architecture  Internal pipelined double-data-rate design with bi-directional differential data strobe (DQS) and on-chip DLL for aligned DQ/DQS timing.
• Memory organization  16M × 16 organization delivering 268.4 Mbit total density with 1KB page size and quad-bank operation.
• Performance and timing  Rated for 600MHz clock (DDR2-1200), with CAS Latency options 3–9 and burst lengths of 4 or 8; typical access/write cycle times specified at 15 ns.
• Power and supply  Standard DDR2 supply: VDD / VDDQ = 1.8V ±0.1V (supported operating range 1.7V–1.9V) suitable for SSTL_18 systems.
• Interface and signal features  Differential clock inputs (CLK/CLKn), DQS edge-aligned for READ and center-aligned for WRITE, data mask (DM), and SSTL_18 compatibility for board-level DDR2 designs.
• Signal integrity and tuning  On-Die Termination (ODT) with selectable ODT values and Off-Chip-Driver (OCD) impedance adjustment for improved signal quality.
• Refresh and low-power modes  Auto and self-refresh support, Partial Array Self Refresh (PASR), High Temperature Self Refresh enable, and JEDEC-compliant refresh rates.
• Package and mounting  84-ball FBGA package (8.0 × 12.5 mm, 0.8 mm ball pitch) offered as die only speed grade for compact surface-mount integration.
• Commercial qualification and compliance  JEDEC-standard DDR2 SDRAM, commercial grade with RoHS compliance and documented electrical/functional specifications.

Typical Applications

• Commercial embedded systems  Implements as board-level volatile memory where a 256Mbit DDR2 device with 1.8V supply and DDR2-1200 timing is required.
• Memory expansion on controller boards  Provides parallel DDR2 storage for designs needing burst lengths of 4 or 8 and selectable CAS latencies for latency/performance trade-offs.
• High-speed buffer and frame storage  Suited for designs that leverage 600MHz operation and on-die termination to maintain signal integrity at high data rates.

Unique Advantages

• DDR2-1200 (600MHz) performance: Delivers high data-rate operation suitable for systems targeting DDR2-1200 timing.
• Flexible timing and burst control: Wide CAS latency support (3–9) and burst length options (4, 8) allow tuning for system timing and throughput needs.
• Signal integrity features: On-Die Termination, OCD impedance adjustment, and differential clock/DQS support reduce board-level signal tuning effort.
• Compact FBGA footprint: 84-ball FBGA (8 × 12.5 mm) supports high-density board layouts while providing a die-only speed grade for custom assembly flows.
• JEDEC standard compliance: Conforms to DDR2 JEDEC specifications and includes standard refresh behavior and self-refresh features for reliable memory operation.
• Commercial-grade operating range: Rated for 0 °C to 95 °C operation and RoHS-compliant materials for mainstream commercial applications.
