Designed for systems that require dense, high-throughput volatile memory in a compact package, this surface-mount 96-ball BGA device provides a broad operating temperature range and a feature set that supports robust signal integrity and memory management.

Key Features

• Memory Architecture — 4.295 Gbit capacity organized as 256M × 16 delivering a DDR4 SDRAM solution with an 8-bit prefetch for high-speed data transfer.
• Performance — 1.6 GHz clock frequency (DDR4-3200 ordering configuration) with access time listed at 13.75 ns and a write cycle time (word page) of 15 ns for responsive memory transactions.
• JEDEC Compliance — JEDEC-qualified DDR4 SDRAM feature set and timing (multiple CAS latency and CWL options) to support standard DDR4 controller interfaces.
• Power and Voltage — JEDEC standard power supply: VDD = VDDQ = 1.2V ±5% with VPP range detailed in the device specification for proper device programming and operation.
• Signal Integrity & Calibration — On-die features including ZQ calibration, nominal/park/dynamic On-Die Termination (ODT), DLL alignment of DQ/DQS to CK, and programmable drive strengths to optimize high-speed signaling.
• Reliability & Data Integrity — Support for Write CRC, Command/Address parity, Data Bus Inversion (DBI) on x16 devices, Data Mask (DM), and per-DRAM addressability for fine-grained mode control.
• Advanced DDR4 Functions — Write leveling, fine granularity refresh, temperature-controlled refresh modes (TCR), low-power auto self-refresh (LP ASR), gear-down modes and programmable preamble for flexible system integration.
• Package & Mounting — 96-ball BGA package, surface-mount mounting type suitable for compact board designs.
• Operating Range — Specified operating temperature from −40 °C to +105 °C to support a wide range of thermal environments.

Typical Applications

• High-speed buffering and frame storage — Use the 4.295 Gbit density and DDR4-3200 configuration for transient data storage and buffering in high-throughput data paths.
• Embedded memory for performance systems — Integrate as main or auxiliary volatile memory where JEDEC-compliant DDR4 operation and x16 organization are required.
• Industrial electronics — Suitable for industrial boards that require dense SDRAM in a compact 96-ball BGA package across a broad temperature range.

Unique Advantages

• Dense x16 organization: 256M × 16 layout provides 4.295 Gbit capacity in a single device, simplifying board-level memory scaling.
• JEDEC-standard compatibility: Broad CAS latency and CWL options plus standard DDR4 behaviors reduce integration effort with compliant memory controllers.
• On-die signal management: ZQ calibration, ODT and DLL support improve signal integrity at high data rates without extra external components.
• Data integrity features: Write CRC, CA parity and DBI (x16) provide additional error-detection and power optimization for high-speed operation.
• Compact BGA packaging: 96-ball BGA surface-mount package enables high-density board designs while retaining accessible thermal and layout characteristics.
