M13S128324A-5BIG2M

The M13S128324A-5BIG2M is a DDR SDRAM device from ESMT in a 1M × 32 organization designed for industrial-grade board-level memory. It implements double-data-rate architecture with a parallel interface and is offered in a 144-ball FBGA surface-mount package for compact system integration.

Targeted at industrial applications, the device combines programmable DDR features and JEDEC qualification with an extended operating range of -40 °C to 85 °C and a supply window of 2.375 V to 2.625 V to support reliable operation in harsh environments.

Key Features

• Memory Organization — 1M × 32 organization with a product designation of 128Mbit; specification lists MemorySize as 134.2 Mbit, providing a wide 32-bit data path for board-level designs.
• DDR Architecture — Double-data-rate operation with two data transfers per clock cycle, differential clock inputs (CLK/CLK̅) and a DLL to align DQ/DQS transitions with CLK.
• Data I/O and Timing — Bi-directional data strobe (DQS) with edge-aligned reads and center-aligned writes; CAS latency options 2, 2.5 and 3; burst lengths 2, 4 and 8 and burst types sequential or interleave.
• Performance — Specified for 200 MHz system clock (ordering information lists this speed as DDR400 for this device) with typical access and write-cycle times of 15 ns.
• Power and I/O — VDD and VDDQ supply range of 2.375 V to 2.625 V; supports 2.5 V I/O (SSTL_2 compatible as documented in the datasheet).
• Refresh and Reliability — Auto and self refresh supported with a 32 ms refresh period (4K cycles); JEDEC qualification noted in the product specifications.
• Package and Mounting — Surface-mount 144-FBGA package (12 mm × 12 mm × 1.4 mm body, 0.8 mm ball pitch) for compact, high-density assembly.
• Industrial Temperature Range — Rated for operation from -40 °C to 85 °C suitable for industrial environments.
• RoHS Compliance — Device is RoHS compliant.

Typical Applications

• Industrial Control — Board-level DDR memory for embedded controllers and industrial automation equipment requiring extended temperature operation and JEDEC-standard behavior.
• Embedded Systems — Compact FBGA package and 32-bit data organization for integration into embedded platforms where board space and interface standardization matter.
• OEM Memory Modules — Suitable for use in custom memory modules or daughtercards where a parallel DDR SDRAM interface and industrial-grade temperature support are required.

Unique Advantages

• Industrial Temperature Range: -40 °C to 85 °C rating enables deployment in harsher operating environments without derating specified by the device.
• JEDEC Qualification: Conformance to JEDEC specifications supports predictable timing, interface behavior, and interoperability in standard DDR designs.
• Flexible DDR Features: Support for CAS latencies 2/2.5/3, multiple burst lengths and both sequential and interleave burst types allows tuning for system performance and access patterns.
• Robust I/O and Timing Alignment: DLL alignment, differential clock inputs and DQS support provide accurate timing for high-reliability data transfers.
• Compact Surface-Mount Package: 144-FBGA footprint delivers high-density integration for space-constrained boards while maintaining a standard ball map for PCB layout.
• Wide Supply Window: 2.375 V–2.625 V VDD/VDDQ range supports system-level power tolerance and stable operation across production variance.
