Overview of M14D2561616A-1.8BG2S – DDR2 SDRAM 256Mbit 533MHz 1.8V 84-FBGA

The M14D2561616A-1.8BG2S is a JEDEC-compliant DDR2 SDRAM device organized as 16M × 16 with a product-class data rate of DDR2-1066 (533 MHz clock). It implements a pipelined double-data-rate architecture with differential DQS and on-chip DLL to align data timing for reliable high-speed transfers.

Designed for surface-mount deployment in an 84-ball FBGA (8 × 12.5 mm) footprint and operating from a 1.7 V to 1.9 V supply, this part targets systems that require standard DDR2 performance, compact package integration, and JEDEC-level interoperability.

Key Features

  • Core & Architecture Internal pipelined double-data-rate design enabling two data accesses per clock cycle; on-chip DLL and differential clock inputs (CLK/CLK̄) for aligned timing.
  • Data Strobe & I/O Bi-directional differential data strobe (DQS/ DQS̄) with edge- and center-aligned modes for READ and WRITE; data I/O transitions on both edges of DQS.
  • Memory Organization 16M × 16 organization with a stated memory size in product specifications of 268.4 Mbit and a 1 KB page size.
  • Performance & Timing 533 MHz clock frequency (DDR2-1066 data rate); supported CAS Latency options 3–9 and additive latency 0–7; burst lengths of 4 and 8.
  • Voltage & Interface Operates from 1.7 V to 1.9 V (VDD = VDDQ = 1.8 V ± 0.1 V) and uses an SSTL_18 interface standard.
  • Signal Integrity & On-Die Features On-Die Termination (ODT) with selectable impedance (50/75/150 Ω), off-chip-driver (OCD) impedance adjustment, and Duty Cycle Corrector (DCC) for improved signal quality.
  • Refresh & Low-Power Options Auto and self-refresh support, Partial Array Self Refresh (PASR), high-temperature self-refresh rate enable; refresh cycles: 8192 cycles/64 ms at 0 °C–85 °C and 8192 cycles/32 ms at >85 °C–95 °C.
  • Package & Mounting 84-FBGA surface mount package (8.0 mm × 12.5 mm × 1.2 mm body, 0.8 mm ball pitch) suitable for space-constrained board designs.
  • Reliability & Compliance JEDEC qualification and RoHS-compliant construction; commercial grade operating range 0 °C to 95 °C.

Typical Applications

  • System Memory for DDR2-1066 Designs Use as main DDR2 SDRAM in systems requiring a DDR2-1066 (533 MHz clock) data rate and JEDEC-compliant timing options.
  • Compact Embedded Systems Surface-mount 84-FBGA package allows integration into space-constrained embedded boards where a 1.8 V DDR2 solution is needed.
  • High-Density Memory Subsystems 16M × 16 organization and selectable CAS/burst timing make this device suitable for designs that require flexible memory timing and standard DDR2 interfaces.

Unique Advantages

  • JEDEC Compliance: Ensures predictable interoperability with other DDR2-compliant components and controllers.
  • Flexible Timing Options: Wide range of CAS latency and additive latency settings (CL 3–9, AL 0–7) to match system timing and performance trade-offs.
  • On-Die Termination & ODT Options: Multiple ODT resistance choices (50/75/150 Ω) and OCD adjustment improve signal integrity for high-speed board layouts.
  • Low-Voltage Operation: Standard 1.8 V supply range (1.7 V–1.9 V) reduces power compared with older nominal-voltage devices while maintaining DDR2 signaling.
  • Compact BGA Footprint: 84-ball FBGA package (8 × 12.5 mm) provides a small PCB footprint for higher system integration density.
  • Robust Refresh & Power Features: Auto/self-refresh, PASR, and temperature-aware refresh intervals support consistent data retention across the specified commercial temperature range.

Why Choose M14D2561616A-1.8BG2S?
