JSL22G328WABQ-25A

The JSL22G328WABQ-25A is a 2 Gbit mobile LPDDR2 SDRAM organized as x32, offered by Jeju Semiconductor for industrial embedded designs. It implements a double-data-rate architecture with differential clock and bidirectional data strobes to support high-throughput memory interfaces.

Targeted at systems that require low-voltage operation and robust temperature performance, this device delivers 533 MHz clock operation (1,066 Mb/s per pin), multi-bank concurrency, and a compact 134-ball BGA package (10.0 × 11.5 mm).

Key Features

• Core Architecture  Double-data-rate (DDR) architecture with commands and addresses sampled on both positive and negative clock edges for efficient data transfer.
• Memory Organization & Density  2 Gbit density organized as x32 to support wide data paths and system-level memory configurations.
• Performance  533 MHz clock rate (–25A speed grade) delivering 1,066 Mb/s per pin; read and write latencies and timing are defined in the LPDDR2 AC timing tables.
• Interface & Signaling  LPDDR2 interface with differential clock inputs (CK/CK#) and differential bidirectional data strobes (DQS/DQS#) for precise data capture; edge-aligned data output and center-aligned data input.
• Power & Voltage  Supports VDD1/VDD2/VDDQ: 1.8 V / 1.2 V / 1.2 V and includes low-power modes such as Deep Power Down, Auto Refresh, Self Refresh, Partial Array Self Refresh, and Temperature Compensated Self Refresh.
• Burst, Mask & Drive  Burst length configurable (default 4, selectable 8 or 16) with data mask (DM) for write data and configurable drive strength.
• Banking & Refresh  Eight internal banks for concurrent operation and auto refresh duty cycle details defined in the datasheet.
• Package & Mounting  Surface-mount 134-FBGA (supplier package 134-BGA, 10.0 × 11.5 mm) for compact board-level integration.
• Industrial Temperature Grade  Rated for operation from −40 °C to 85 °C (industrial grade).

Typical Applications

• Mobile and Handheld Devices  High-bandwidth LPDDR2 memory for compact mobile and handheld platforms requiring low-voltage operation.
• Industrial Embedded Systems  Memory for industrial controllers and instrumentation where extended temperature range and robust refresh/low-power modes are needed.
• Consumer and IoT Edge Devices  Local application memory for edge compute modules and connected devices that benefit from LPDDR2 power-saving modes and compact BGA packaging.

Unique Advantages

• High Throughput at Low Voltage: 533 MHz clock (1,066 Mb/s per pin) operation combined with 1.2 V/1.8 V supply domains enables high data rates with LPDDR2 low-voltage benefits.
• Flexible Burst and Masking Options: Configurable burst lengths (4/8/16) and write data mask (DM) provide design flexibility for varied transfer patterns.
• Comprehensive Low-Power Modes: Deep Power Down plus multiple refresh/self-refresh modes (including partial and temperature-compensated self refresh) reduce system power during idle periods.
• Industrial Temperature Range: −40 °C to 85 °C rating supports deployment in temperature-challenging industrial environments.
• Compact BGA Package: 134-ball FBGA (10.0 × 11.5 mm) enables dense board integration for space-constrained designs.
• Robust Signaling: Differential clock and bidirectional DQS/DQS# strobes with defined edge/center alignment behavior simplify timing and data capture strategies.
