M12L64322A-5TG2S

The M12L64322A-5TG2S is a synchronous DRAM device organized as 4 × 524,288 words by 32 bits, providing 67,108,864 bits (≈67.11 Mbit) of volatile memory in a 4‑bank architecture. Designed to the JEDEC 3.3V standard and rated for operation up to 200 MHz, it supports synchronous, burstable transfers and versatile timing options for memory subsystems.

This surface‑mount 86‑lead TSOP II package offers a compact footprint and JEDEC compliance with features such as programmable CAS latencies, selectable burst lengths and auto/self‑refresh—making it suitable for high‑bandwidth, high‑performance memory system applications that require a parallel SDRAM interface and standard 3.0–3.6 V supply.

Key Features

• Core & Organization  4 banks of 512K × 32 organization (4 × 524,288 × 32) delivering 67,108,864 bits of synchronous DRAM storage.
• Performance  200 MHz maximum clock frequency with an access time of 4.5 ns and word/page write cycle time of 10 ns to support fast synchronous transfers.
• CAS & Burst Control  Programmable CAS latency options (2 and 3) and selectable burst lengths (1, 2, 4, 8 and full page) with sequential and interleave burst types for flexible throughput control.
• Interface & Timing  All inputs are sampled on the positive edge of the system clock; supports LVTTL compatible multiplexed addresses, burst read single‑bit write operations, and DQM masking.
• Refresh & Power Management  Auto and self‑refresh support with a 64 ms refresh period (4K cycle); JEDEC standard 3.3V supply range (3.0 V to 3.6 V).
• Package & Mounting  86‑lead TSOP II (TSOPII 86L) surface‑mount package for compact board integration; Pb‑free and RoHS compliant.
• Qualification & Operating Range  JEDEC qualification; commercial temperature grade with operating range 0 °C to 70 °C.

Typical Applications

• High‑Bandwidth Memory Subsystems  Designed for systems requiring synchronous, burstable DRAM to support sustained data throughput and predictable timing behavior.
• Embedded Memory Modules  Suitable for embedded designs that require a JEDEC‑standard 3.3V SDRAM in a compact TSOP II surface‑mount package.
• Performance‑Oriented Consumer Electronics  Used where selectable CAS latency and burst modes enable tuning for specific performance and latency targets.

Unique Advantages

• Flexible Timing Options: Programmable CAS latencies and multiple burst lengths allow designers to optimize latency and throughput for target applications.
• Synchronous, Predictable Operation: All inputs sampled on the clock’s positive edge and support for LVTTL multiplexed addressing enables precise cycle control in synchronous designs.
