M14D1G8128A-2.5BG2P

The M14D1G8128A-2.5BG2P is a JEDEC-standard DDR2 SDRAM organized as 128M × 8 (1.074 Gbit) in a compact 60-ball FBGA package. It implements an internal pipelined double-data-rate architecture with on-chip DLL and differential clock inputs to deliver DDR2-800 timing at a 400 MHz core clock (DDR transfer).

Designed for systems that require JEDEC-compliant DDR2 memory in a low-voltage 1.8 V class solution, this device provides selectable latencies and burst modes along with on-die termination and ODT impedance options for improved signal integrity in space-constrained designs.

Key Features

• Memory Organization — 128M × 8 bit configuration for a total of 1.074 Gbit of volatile DRAM capacity.
• DDR2 Architecture — Internal pipelined double-data-rate operation with two data transfers per clock cycle and on-chip DLL for timing alignment.
• Data Rate and Timing — Designed for DDR2-800 operation (400 MHz clock, DDR transfers); ordering grade M14D1G8128A-2.5BG2P corresponds to DDR2-800 (5-5-5) timing.
• Flexible Latency and Burst — CAS Latency options and additive latency settings; burst length 4 or 8 with sequential and interleave burst types.
• Signal and I/O — Bi-directional differential data strobe (DQS/ĎQS), differential clock inputs (CLK/ĹCLK), and SSTL_18 interface for standard DDR2 signaling.
• On-Die Termination & ODT — On-die-termination with selectable 50/75/150 Ω ODT and off-chip-driver impedance adjustment to support signal integrity.
• Power — Low-voltage operation with VDD/VDDQ = 1.8 V ± 0.1 V (specified supply range 1.7 V to 1.9 V).
• Refresh and Reliability — JEDEC refresh support: 8192 cycles/64 ms for 0 °C ≤ Tc ≤ +85 °C and 8192 cycles/32 ms for +85 °C < Tc ≤ +95 °C.
• Package & Mounting — Compact 60-FBGA surface-mount package, qualified to JEDEC and supplied as a commercial-grade, RoHS-compliant device.
• Operating Range — Commercial operating temperature from 0 °C to 95 °C.

Typical Applications

• JEDEC-standard DDR2 memory subsystems — Use where a 1.074 Gbit DDR2 device with standard timing and refresh behavior is required.
• Compact FBGA board designs — For systems that require a small 60-ball FBGA footprint combined with DDR2-800 performance.
• Low-voltage DDR2 designs — Suitable for designs requiring 1.8 V ±0.1 V supply operation and SSTL_18 signaling.
• Temperature-constrained commercial applications — For applications operating within a 0 °C to 95 °C ambient temperature range that rely on JEDEC refresh rates.

Unique Advantages

• JEDEC compliance: Provides standard DDR2 behavior and refresh sequences for predictable system integration.
• Compact high-density memory: 1.074 Gbit in a 60-FBGA package reduces PCB area while delivering ample DRAM capacity.
• Flexible timing options: Multiple CAS and additive latency settings plus burst modes accommodate system-level timing trade-offs.
• Signal integrity features: On-die termination and selectable ODT impedance help simplify board-level termination and improve data margins.
• Low-voltage operation: 1.8 V nominal supply with defined 1.7 V–1.9 V range supports standard DDR2 power domains.
• Commercial-grade reliability: JEDEC qualification and RoHS compliance for mainstream production environments.
