Overview of JSL21G168WABQ-25 – 1Gb LPDDR2 Mobile SDRAM (x16, 400 MHz, Industrial)
The JSL21G168WABQ-25 from Jeju Semiconductor is a 1 Gbit volatile mobile LPDDR2 SDRAM organized as x16. It implements a double-data-rate architecture with differential clock and data strobe signaling to support high-rate synchronous memory operations.
Designed for applications that require compact, high-density DRAM in a surface-mount 134-FBGA package (10.0×11.5 mm), this part targets mobile and industrial embedded systems where performance, configurable burst behavior, and extended temperature operation matter.
Key Features
- Core Architecture Double-data-rate LPDDR2 architecture with data transfers on both clock edges and bidirectional data strobes (DQS/DQS#) for reliable high-speed operation.
- Memory Organization & Capacity 1 Gbit density organized as x16 (64M ×16, 8 banks) providing a compact footprint for system memory or buffer applications.
- Clock & Performance 400 MHz clock frequency (DDR transfers) with selectable burst lengths (4 default, 8 or 16) and burst types (sequential or interleave).
- Power Domains & Supply VDD1 / VDD2 / VDDQ rails supported at 1.8V / 1.2V / 1.2V respectively, consistent with LPDDR2 platform requirements.
- Power Management Supports Auto Refresh, Self Refresh, Partial Array Self Refresh, Temperature Compensated Self Refresh and Deep Power Down modes for controlled retention and power sequencing.
- Interface & Controls Differential clock inputs (CK/CK#), command/address on both CK edges, data and data mask referenced to both edges of DQS; includes data mask (DM) for write operations and configurable drive strength.
- Internal Architecture Eight internal banks for concurrent operation and no on-die DLL (CK to DQS is not synchronized); edge-aligned outputs and center-aligned inputs.
- Package & Mounting Surface-mount 134-FBGA package, supplier device package 134-BGA (10.0×11.5 mm), suitable for space-constrained board designs.
- Industrial Grade Temperature Rated for operation from −40°C to 85°C for industrial environments.
- Standards & Compatibility Implements LPDDR2 interface signaling and timing conventions including bidirectional DQS and differential clocks for system-level interoperability.
Typical Applications
- Mobile and Handheld Devices High-density LPDDR2 memory suitable for mobile platforms requiring compact, synchronous DRAM.
- Industrial Embedded Systems Industrial temperature rating (−40°C to 85°C) makes it appropriate for embedded controllers and instrumentation in harsh environments.
- Space-Constrained Modules 134-FBGA (10.0×11.5 mm) packaging enables dense memory integration in small form-factor modules and single-board computers.
Unique Advantages
- High Throughput DDR Operation DDR architecture at a 400 MHz clock rate enables two data transfers per clock cycle for increased memory bandwidth.
- Flexible Burst Control Configurable burst lengths (4, 8, 16) and burst types (sequential/interleave) let designers tune access patterns for system requirements.
- Comprehensive Power Modes Auto Refresh, Self Refresh variants and Deep Power Down provide multiple retention and power-saving options to match application power profiles.
- Industrial Temperature Range Specified −40°C to 85°C operation supports deployment in temperature-extreme industrial applications.
- Compact, Surface-Mount Package 134-FBGA (10.0×11.5 mm) package reduces PCB area for compact designs while delivering 1 Gbit density.
- Robust Signaling Differential clocking and bidirectional DQS/DQS# strobe support reliable high-speed interface timing and data capture.
