M12L64322A (2S)

The M12L64322A (2S) is a synchronous DRAM (SDRAM) organized as 4 × 524,288 words by 32 bits for a total of 67,108,864 bits (67.11 Mbit). It implements a four-bank SDRAM architecture with programmable burst length and CAS latency options for predictable, clock-synchronous memory transactions.

Designed for industrial-grade operation with an operating temperature range of −40 °C to 85 °C and JEDEC-standard 3.3V power supply, the device supports up to 200 MHz operation and features timing options suited to embedded and industrial system designs requiring deterministic memory behavior.

Key Features

• Core & Memory Architecture 67,108,864-bit SDRAM organized as 2M × 32 (4 × 524,288 × 32), four-bank operation for efficient interleaved access patterns.
• Performance Supports up to 200 MHz clock frequency, 5 ns access time and selectable CAS latency (2 & 3); write cycle time (word/page) specified at 15 ns to enable high-rate read/write cycles.
• Burst and Transfer Flexibility Programmable burst lengths (1, 2, 4, 8 & full page) and burst type (sequential & interleave) for adaptable data transfer modes.
• Interface & Signaling Synchronous parallel SDRAM interface with LVTTL-compatible inputs and all inputs sampled on the positive edge of the system clock for deterministic timing.
• Power & Standards JEDEC-standard 3.3V power supply and JEDEC qualification ensure standardized electrical behavior and interoperability with JEDEC-compliant systems.
• Reliability & Refresh Auto and self-refresh capability with a 64 ms refresh period (4K cycle) and DQM masking for robust data integrity and low-maintenance operation.
• Package & Mounting Available in industrial surface-mount packages: 86-lead TSOPII and 90-ball BGA options to match board-level space and assembly requirements.
• Industrial Temperature Grade Specified for −40 °C to 85 °C operation to support industrial and other temperature-demanding environments.

Typical Applications

• Industrial Control Use in embedded controllers and automation systems that require wide temperature operation and predictable synchronous memory timing.
