JSL22G328WABQ-25AM

The JSL22G328WABQ-25AM is a 2Gbit mobile LPDDR2 SDRAM device organized as x32. It implements a double-data rate architecture with differential clock and data strobe inputs for high-speed synchronized transfers. This device targets designs that require a compact, surface-mount LPDDR2 memory solution offering 533 MHz clock operation (1,066 Mb/s per pin data rate) and support for advanced low-power modes.

Key Features

• Memory Core Double-data rate LPDDR2 SDRAM architecture supporting two data transfers per clock cycle and 8 internal banks for concurrent operation.
• Performance 533 MHz clock rate delivering 1,066 Mb/s per pin data rate (speed grade −25A with Read Latency 8 / Write Latency 4 as defined in the datasheet).
• Data Path and Timing Differential clock inputs (CK/CK#) and bidirectional differential data strobes (DQS/DQS#); commands and addresses sampled on both clock edges; burst length options 4 (default), 8, or 16 with sequential or interleave burst types.
• Power and Voltage Multi-voltage domains VDD1/VDD2/VDDQ of 1.8V/1.2V/1.2V and support for deep power down, auto refresh, self refresh, and temperature-compensated self refresh modes to minimize active and standby power.
• Write and Read Controls Data mask (DM) for write operations and Auto Precharge option per burst access for efficient memory transactions.
• Drive & I/O Behavior Configurable drive strength, edge-aligned data output and center-aligned data input timing for robust signal capture.
• Package & Mounting 134-FBGA surface-mount package (supplier package 134-BGA, 10.0 × 11.5 mm) suitable for compact board layouts.
• Temperature Range Specified operating temperature from −40 °C to 105 °C for use across broad thermal environments.

Typical Applications

• Mobile and Portable Devices LPDDR2 interface and low-voltage operation make it suitable for onboard memory in mobile and portable electronics requiring high data throughput.
• Embedded Systems Acts as system memory for SoCs and embedded processors that support LPDDR2 x32 interfaces and need compact BGA packaging.
• Low-Power Designs Power-management features like self refresh and deep power down enable lower standby consumption in battery-operated or energy-conscious systems.

Unique Advantages

• High Sustained Bandwidth: 533 MHz operation provides 1,066 Mb/s per pin data throughput for demanding memory transactions.
• Flexible Burst and Bank Structure: Burst length options and 8 internal banks enable efficient access patterns and improved concurrency for multi-threaded memory workloads.
• Multi-Domain Voltages: 1.8V and 1.2V domains offer compatibility with common LPDDR2 power architectures and allow targeted power optimization.
• Advanced Power Modes: Auto Refresh, Self Refresh, Partial Array Self Refresh and Deep Power Down reduce active and idle power usage in duty-cycled applications.
• Compact BGA Footprint: 134-FBGA (10.0 × 11.5 mm) surface-mount package supports space-constrained PCB designs without sacrificing capacity.
• Wide Operating Temperature: −40 °C to 105 °C rating supports deployment across a wide range of thermal environments.
