M14D2561616A-1.5BG2S

The M14D2561616A-1.5BG2S is a DDR2 SDRAM device from ESMT organized as 16M × 16 for a 256Mbit class memory density. It implements an internal pipelined double-data-rate architecture with differential clock inputs and on-chip DLL to support two data accesses per clock cycle.

This JEDEC-standard DDR2 component operates at up to 667 MHz with a nominal 1.8 V supply (1.7 V–1.9 V range), and is delivered in an 84-ball FBGA (8 × 12.5 mm) package for surface-mount applications requiring a compact parallel memory interface.

Key Features

• Memory Organization and Density — 16M × 16 organization delivering a 256Mbit class device suitable for parallel memory systems.
• DDR2 Architecture — Internal pipelined double-data-rate operation with bi-directional differential data strobe (DQS) and differential clock inputs (CLK/CLK̅) for DDR2 timing and data transfer.
• Performance and Timing — Supports up to 667 MHz clock frequency (DDR2-1333 data rate) with selectable CAS latencies from 3 to 9 and burst lengths of 4 and 8; write cycle time and access time parameters include 15 ns figures where specified.
• Signal Integrity and Timing Control — On-chip DLL, DQS alignment (edge-aligned for READ, center-aligned for WRITE), On-Die Termination (ODT) and OCD impedance adjustment for enhanced signal quality; DCC (Duty Cycle Corrector) supported.
• Refresh and Power Management — Auto and self-refresh support with defined refresh intervals (8192 cycles/64 ms at 0 °C to +85 °C; 8192 cycles/32 ms at +85 °C to +95 °C) and Partial Array Self Refresh (PASR) capability.
• Voltage and Interface Standards — Nominal VDD = 1.8 V (operating range 1.7 V–1.9 V) and SSTL_18 interface compatibility for standard DDR2 signaling.
• Package and Environmental — 84-FBGA (8 × 12.5 mm, 0.8 mm ball pitch) surface-mount package; RoHS compliant.
• Qualification — JEDEC standard compliant DDR2 SDRAM.

Typical Applications

• Systems requiring compact parallel DDR2 memory — Use where a 256Mbit DDR2 SDRAM in an 84-FBGA package with a 16M × 16 organization is required.
• Designs needing defined voltage and timing ranges — Suited to designs that operate within the 1.7 V–1.9 V supply window and require DDR2 timing modes up to 667 MHz.
• Low-profile module implementations — Applicable for board-level implementations that demand surface-mount FBGA memory in a compact footprint.

Unique Advantages

• DDR2-1333 data-rate capability — Rated for 667 MHz operation supporting DDR2-1333 throughput (specified timing example: 9-10-10) for designs targeting this data rate.
• Flexible timing options — Multiple CAS latency and additive latency settings provide tuning options for system timing and performance trade-offs.
• Improved signal quality — On-Die Termination, OCD impedance adjustment and differential DQS/CLK inputs help maintain signal integrity on high-speed memory buses.
• Power and refresh flexibility — Auto/self-refresh, PASR and specified refresh intervals across temperature ranges support reliable data retention and power management.
• JEDEC standard and RoHS compliant — Ensures adherence to industry memory standards and environmental compliance.
• Compact FBGA packaging — 84-ball FBGA (8 × 12.5 mm) provides a small board footprint for space-constrained applications.
