JSL22G168WA

The JSL22G168WA is a 2 Gbit volatile LPDDR2 SDRAM device organized as x16, implementing a double-data-rate architecture for high-throughput mobile memory applications. It is built for low-voltage mobile SDRAM environments and supports standard LPDDR2 interface signaling and timing.

With a 400 MHz clock (800 Mb/s per pin data rate at the 400 MHz grade), on-die features for power management, and configurable drive strength, this device targets mobile and embedded systems that require low-voltage SDRAM with flexible refresh and burst options.

Key Features

• Memory Capacity & Organization — 2 Gbit density organized as x16 for parallel data paths and system memory expansion.
• LPDDR2 Double-Data-Rate Architecture — Two data transfers per clock cycle with differential clock inputs (CK/CK#) and differential data strobes (DQS/DQS#) for DDR operation.
• Clock & Data Rate — 400 MHz clock frequency supporting an 800 Mb/s per-pin data rate for the 400 MHz speed grade.
• Burst and Bank Configuration — Burst length configurable to 4 (default), 8 or 16 with sequential or interleave burst types; 8 internal banks for concurrent operation.
• Power Domains & Low-Voltage Operation — VDD1/VDD2/VDDQ levels listed as 1.8V / 1.2V / 1.2V / 1.2V and support for Auto Refresh, Self Refresh, Partial Array Self Refresh, Temperature Compensated Self Refresh and Deep Power Down modes.
• Write Controls & Data Integrity — Data mask (DM) for write data and edge-aligned data output / center-aligned data input timing built into the LPDDR2 architecture.
• Timing & Interface — Commands and addresses sampled on both positive and negative edges of CK; data and data mask referenced to both edges of DQS. No DLL (CK to DQS not synchronized).
• Drive & Input Compatibility — Configurable drive strength and HSUL_12 compatible inputs for interface tuning.
• Operating Temperature Grades — Series supports multiple operating ranges: Standard (−25 to 85 °C), Industrial (−40 to 85 °C), and Extended (85 to 105 °C).
• Package & Mounting — Surface mount mounting type; supplier device package listed as Die.
• Environmental Compliance — RoHS compliant.

Typical Applications

• Mobile devices — Low-voltage LPDDR2 architecture and high per-pin data rates make this device suitable for memory subsystems in mobile platforms.
• Portable consumer electronics — Supports compact, low-power memory implementations that require burst access and efficient refresh modes.
• Embedded mobile systems — Offers configurable drive strength and multiple power-saving refresh modes useful for embedded designs with thermal or power constraints.

Unique Advantages

• High data throughput — Double-data-rate operation at a 400 MHz clock yields an 800 Mb/s per-pin data rate for responsive memory transfers.
• Flexible burst and bank architecture — Multiple burst lengths (4/8/16) and eight internal banks enable efficient, concurrent memory accesses.
• Comprehensive low-power modes — Auto Refresh, Self Refresh, Partial Array Self Refresh, Temperature Compensated Self Refresh and Deep Power Down support reduced power consumption across use scenarios.
• Multi-grade temperature support — Available operating ranges from −40 °C up to 105 °C across grades to match thermal requirements of different designs.
• Voltage domain flexibility — Documented VDD1/VDD2/VDDQ voltage levels for integration into low-voltage mobile power rails.
• Design-level interface control — Differential clocking, bidirectional DQS, and configurable drive strength allow signal integrity tuning for target system designs.
