JSR362G168NHR-A

The JSR362G168NHR-A is a 2 Gbit DDR3 SDRAM device manufactured by Jeju Semiconductor in a 96‑ball FBGA (7.5 × 13 mm) surface‑mount package. It implements DDR3 SDRAM architecture with x16 organization and is specified for commercial‑grade applications.

This device delivers high‑speed, double‑data‑rate memory operation with a 1.5 V supply and support for data rates up to 2133 MT/s. It is intended for commercial electronic designs that require compact, high‑bandwidth volatile memory in a lead‑free, RoHS‑compliant package.

Key Features

• Memory Capacity & Organization – 2 Gbit density organized as 128M × 16 bits, providing a 2 KB page size in x16 configuration.
• High‑Speed DDR3 Interface – Supports DDR3 datapaths with data rates up to 2133 MT/s; listed timing for the -A speed grade targets 2133 MT/s with an access time of 13.09 ns.
• Voltage & Power – Standard DDR3 1.5 V supply (VDD, VDDQ), backward compatible with DDR3 operation noted in the specification set.
• Package & Mounting – 96‑ball FBGA (96‑BGA, 7.5 × 13 mm) surface‑mount package optimized for compact board designs.
• Commercial Operating Range – Specified operating temperature range: 0 °C to 85 °C.
• DDR3 Architecture Features – Eight internal banks, 8‑bit prefetch pipelined architecture, double data‑rate transfers, burst lengths 8 and 4 (with Burst Chop), and programmable CAS latency and CAS write latency options.
• Signal Integrity & Calibration – On‑Die Termination (ODT) options, ZQ calibration for DQ drive and ODT, DLL alignment, and programmable output driver impedance control.
• Reliability & Maintenance – Auto‑refresh and self‑refresh support, programmable partial array self‑refresh (PASR), and Multi‑Purpose Register (MPR) for predefined pattern readout.
• Environmental Compliance – Lead‑free and RoHS compliant.

Typical Applications

• Commercial electronic platforms – Acts as system memory where dense, high‑bandwidth volatile storage is required in space‑constrained board designs.
• High‑bandwidth buffering – Suitable for buffering and temporary data storage where DDR3 interface and burst transfers improve throughput.
• Embedded memory subsystems – Fits embedded designs that require standard DDR3 timing flexibility and compact FBGA packaging.

Unique Advantages

• High effective data throughput – Supports data rates up to 2133 MT/s and a 1.5 V DDR3 interface, enabling high bandwidth in commercial systems.
• Flexible timing options – Multiple CAS latency and CAS write latency settings allow tuning to system timing and performance requirements (CL and CWL options listed in the specification set).
• Compact SMD footprint – 96‑FBGA (7.5 × 13 mm) package provides a small board area for dense designs without sacrificing capacity.
• Signal quality and calibration – On‑Die Termination variants and ZQ calibration support improve signal integrity and consistent drive characteristics across assemblies.
• Power and refresh controls – Auto‑refresh, self‑refresh, and programmable PASR reduce refresh overhead and help manage power in commercial applications.
• Standards‑based DDR3 feature set – Implements DDR3 primitives such as DQS strobes, DLL alignment, burst modes and MPR, ensuring predictable behavior in DDR3 memory controllers.
