M12L5121632A-6T(2T)

The M12L5121632A-6T(2T) is a synchronous DRAM device from ESMT offering 536,870,912 bits of organized memory as 4 × 8,388,608 words × 16 bits (32M × 16). Its synchronous architecture and programmable operating modes make it suitable for high-bandwidth, high-performance memory system applications.

Designed to operate with JEDEC-standard 3.3V power and LVTTL-compatible inputs, the device supports multiple CAS latencies and burst modes to match system timing and throughput requirements.

Key Features

• Memory Organization & Capacity — 536,870,912 bits organized as 4 × 8,388,608 words × 16 bits (reported as 536.9 Mbit / 32M × 16).
• Performance — Specified up to 166 MHz with a 5 ns access time and word/page write cycle time of 12 ns; supports CAS latency settings of 2 and 3.
• Banking and Burst Control — Four-bank operation with programmable burst length (1, 2, 4, 8, full page) and selectable burst type (sequential & interleave) for flexible data transfers.
• Synchronous Interface — All inputs are sampled on the positive-going edge of the system clock; supports burst read and single write operation and DQM for masking.
• Power and Refresh — JEDEC standard 3.3V power supply (as noted in product documentation) with auto and self-refresh support and a 64 ms refresh period (8K cycle).
• Packages & Mounting — Surface-mount device available in 54-pin TSOP II and 54-ball FBGA package options (TSOP II 54L / BGA54).
• Operational & Regulatory — Commercial grade with JEDEC qualification, RoHS-compliant, and operating temperature range of 0°C to 70°C.

Typical Applications

• High-bandwidth memory subsystems — For systems that require synchronous DRAM with programmable burst modes and CAS latency options to adapt to varying throughput needs.
• High-performance memory designs — Suited to designs leveraging four-bank operation and burst transfers to manage sustained data streams.
• Synchronous clocked systems — For designs that sample inputs on clock edges and require precise cycle control for predictable I/O timing.

Unique Advantages

• High single-device capacity: 536.9 Mbit in a single SDRAM device provides substantial on-board memory without multi-device assemblies.
• Configurable timing: CAS latency (2 & 3) and programmable burst lengths enable designers to tune latency versus throughput to meet system requirements.
• Four-bank architecture: Four independent banks allow flexible access patterns and bank management to support complex memory operations.
• JEDEC-standard interface: 3.3V JEDEC compatibility and LVTTL-compatible multiplexed address inputs simplify integration into standards-compliant systems.
• Package flexibility: Choice of 54-pin TSOP II or 54-ball FBGA supports different PCB form factors and assembly processes.
• Production-ready compliance: JEDEC qualification and RoHS compliance support commercial production requirements within a 0°C to 70°C operating range.
