JSL22G328WA

The JSL22G328WA is a 2 Gbit volatile LPDDR2 SDRAM organized x32 and supplied as a die for surface-mount integration. It implements a double-data rate architecture with differential clock and data strobe signaling to deliver low-voltage, high-bandwidth memory for mobile and embedded designs.

This device targets designs that require LPDDR2-class performance and power management, offering 400 MHz clock operation (800 Mb/s per pin), multi-bank concurrency and a range of refresh and low-power modes documented by Jeju Semiconductor.

Key Features

• Core / Memory Architecture Double-data rate LPDDR2 architecture with 8 internal banks for concurrent operation; supports burst lengths of 4 (default), 8 or 16 and sequential or interleave burst types.
• Performance 400 MHz clock frequency delivering 800 Mb/s per pin (data rate) for the specified speed grade; read/write latencies and timing defined in the LPDDR2 AC timing tables.
• Interface & Timing Differential clock inputs (CK / CK#) and differential data strobes (DQS / DQS#) with bidirectional DQS for accurate data capture; commands and addresses are sampled on both clock edges.
• Data Alignment Edge-aligned data output and center-aligned data input for DDR signaling behavior; note CK-to-DQS is not synchronized (No DLL) as specified.
• Power & Voltage Multi-rail operation with VDD1/VDD2/VDDQ specified at 1.8V/1.2V/1.2V; supports Auto Refresh, Self Refresh, Partial Array Self Refresh, Temperature Compensated Self Refresh and Deep Power Down mode for low-power operation.
• Write Mask & Drive Data mask (DM) for write operations and configurable drive strength to tune interface signalling.
• Package & Mounting Supplier device package listed as Die with surface mount mounting type for compact integration into custom packages or PoP stacks.
• Operating Temperatures Standard and extended temperature grades documented: −25 to 85°C (Standard), −40 to 85°C (Industrial), and 85 to 105°C (Extended) as provided in the product documentation.
• Compliance RoHS compliant.

Typical Applications

• Mobile and Portable Devices Use as mobile LPDDR2 memory in compact, power-sensitive platforms requiring DDR transfer rates and low-voltage operation.
• Embedded Systems Suitable for embedded designs that need a 2Gb volatile memory device with multi-bank concurrency and flexible burst behavior.
• Consumer Electronics Integration into handheld or compact consumer modules where low-power self-refresh modes and configurable drive strength are beneficial.

Unique Advantages

• DDR Performance at Low Voltage 400 MHz operation with 1.8V/1.2V/1.2V rails provides high data throughput while maintaining LPDDR2 power characteristics.
• Flexible Burst and Bank Architecture Multiple burst length options and 8 internal banks enable efficient memory access patterns and improved throughput for bursty workloads.
• Comprehensive Power Modes Auto Refresh, Self Refresh, Partial Array Self Refresh, Temperature Compensated Self Refresh and Deep Power Down provide designers with multiple strategies to reduce power consumption.
• Interface Integrity Differential clock and data strobe signaling with configurable drive strength supports robust high-speed interface timing and signal integrity tuning.
• Broad Temperature Coverage Documented standard, industrial and extended temperature ranges allow selection for designs operating across varied thermal environments.
• RoHS Compliant Meets RoHS requirements for environmental compliance in applicable assemblies.
