Key Features

• Memory Core & Organization 4.295 Gbit capacity organized as 32M×16 I/Os×8 banks (256M×16 logical organization) with a 2KB page size per bank.
• Performance Operates at a 933 MHz clock (DDR3(L)-1866 / 1866 Mb/sec per pin) with 8n prefetch architecture and double-data-rate transfers on DQ, DQS and DM.
• Interface & Signal Differential clock (CK/CK) and data strobe (DQS/DQS) for source-synchronous transfers, programmable drive strength (DS), and configurable On-Die Termination (ODT) for system compatibility.
• Voltage & Power Supports SSTL_135 (VDD/VDDQ = 1.35V) and SSTL_15 (VDD/VDDQ = 1.5V) power rails, with Auto Refresh, Self Refresh, Partial Array Self Refresh (PASR), and Power Down modes for power management.
• Timing & Programmability Wide range of programmable CAS Latency (5–16), CAS Write Latency (5–12), additive latency options, write recovery times, burst length/type and on-the-fly BC/BL switching.
• Calibration & Signal Integrity ZQ calibration via external ZQ pad (240 Ω ±1%) and support for write/read leveling features to aid reliable interface timing and impedance accuracy.
• Package & Environmental Pb‑free 96 ball BGA surface-mount package, industrial grade, JEDEC qualified, RoHS compliant, and rated for operation from −40°C to 95°C.
• Latency & Access Typical access time 13.75 ns and write cycle time (word page) of 15 ns for predictable memory timing characteristics.

Typical Applications

• Industrial Embedded Systems — Industrial-grade temperature range and JEDEC compliance make the device suitable for embedded controllers and edge computing modules used in industrial environments.
• High-Speed Memory Subsystems — DDR3(L)-1866 data rates and 8n prefetch architecture support general high-throughput memory tasks in systems that require fast sequential and random access.
• Board-Level Memory Expansion — 96 ball BGA surface-mount package and 256M×16 organization provide a compact footprint for board-level memory expansion in space-constrained designs.

Unique Advantages

• Dual Voltage Flexibility: Supports both 1.35V and 1.5V operation (SSTL_135 and SSTL_15), enabling compatibility with systems using either DDR3L or legacy DDR3 voltage rails.
• Configurable Timing and Termination: Extensive CAS, write recovery and ODT settings allow designers to tune performance and signal integrity for varied system requirements.
• Signal Calibration and Reliability: ZQ calibration and read/write leveling features improve impedance accuracy and timing robustness across PCB and system variations.
