M14D5121632A-2.5BG2S

The M14D5121632A-2.5BG2S is a DDR2 SDRAM device with 536.9 Mbit density organized as 32M × 16. It implements an internal pipelined double-data-rate architecture and quad-bank operation to deliver two data accesses per clock cycle for systems that require parallel DDR2 memory.

Designed for 1.8 V operation (VDD = 1.8V ±0.1V) and JEDEC qualification, this device offers DDR2-800 performance at a 400 MHz clock rate in an 84-ball FBGA package (8 mm × 12.5 mm, A(max)=1.2 mm), and is RoHS compliant.

Key Features

• Core architecture  Internal pipelined double-data-rate architecture with on-chip DLL and differential clock inputs (CLK / CLK̄) enabling two data transfers per clock cycle.
• Memory size & organization  536.9 Mbit density organized as 32M × 16 (8M × 16 × 4 banks) supporting DDR2-800 operation for the -2.5BG2S option.
• Performance & timing  400 MHz clock frequency with write cycle time and access time specified at 15 ns; supports CAS latency options 3–9 and additive latency 0–7, with burst length 4 or 8 and sequential/interleave burst types.
• Power & voltage  Nominal supply VDD = 1.8V ±0.1V (device voltage supply range 1.7V–1.9V) with VDDQ supplied for DQ I/O and VDDL for DLL.
• Interfaces & I/O  SSTL_18 interface with bi-directional differential data strobe (DQS / DQS̄) and data I/O transitions on both edges of DQS; separate DM inputs (LDM, UDM) for write masking.
• Signal integrity & on-die features  On-Die Termination (ODT), Off-Chip-Driver (OCD) impedance adjustment, and selectable ODT impedances (50 / 75 / 150 Ω) to improve signal quality.
• Refresh & power management  Auto and self-refresh support, Partial Array Self Refresh (PASR), high-temperature self-refresh rate enable, and defined refresh cycles for 0 °C–85 °C and 85 °C–95 °C ranges.
• Package & environmental  84-ball FBGA (8 × 12.5 mm) with maximum body thickness 1.2 mm; RoHS compliant and commercial grade with operating temperature 0 °C to 95 °C.

Typical Applications

• Memory subsystem designs  Use where a 536.9 Mbit, 32M × 16 DDR2 memory element is required to implement on-board DRAM capacity in parallel-interface systems.
• Compact board-level implementations  84-FBGA (8 × 12.5 mm, 1.2 mm max) package fits space-constrained PCBs that need 1.8 V DDR2 memory.
• Systems requiring JEDEC-qualified DDR2  Suitable for designs that require JEDEC-standard DDR2 SDRAM timing, refresh behavior, and SSTL_18 interface characteristics.

Unique Advantages

• High-density DDR2 memory: 536.9 Mbit capacity (32M × 16) provides significant on-board memory in a single device.
• Flexible timing options: Supports a wide range of CAS latencies (3–9) and additive latencies (0–7) to match system timing requirements.
• Signal integrity controls: On-Die Termination and OCD impedance adjustment with selectable ODT values (50/75/150 Ω) help manage I/O signaling on high-speed boards.
• Low-voltage operation: 1.8 V nominal supply (1.7 V–1.9 V range) aligns with standard DDR2 power domains for consistent system integration.
• Compact, production-ready package: 84-ball FBGA (8 × 12.5 mm, A(max)=1.2 mm) provides a small footprint and is supplied RoHS compliant for modern production flows.
• JEDEC qualification: JEDEC-standard DDR2 features and defined refresh behavior simplify qualification and system validation.
