Overview of M12L5121632A-7T(2T) – SDRAM 3.3V

The M12L5121632A-7T(2T) from ESMT is a synchronous DRAM device organized as 4 × 8,388,608 words by 16 bits for a total density of 536.9 Mbit. It implements a synchronous SDRAM architecture with programmable burst lengths and latencies to support high-bandwidth, high-performance memory system applications.

Designed for surface-mount assembly, the device is offered in TSOP II and BGA54 packages and carries JEDEC qualification with RoHS-compliant, Pb‑free construction. Typical system uses include high-throughput memory subsystems where predictable, clocked DRAM timing and flexible access modes are required.

Key Features

  • Memory Core & Organization 536.9 Mbit capacity organized as 32M × 16 (4 banks of 8,388,608 words × 16 bits), delivering wide 16-bit parallel data paths for system memory designs.
  • Synchronous SDRAM Architecture All inputs are sampled on the positive edge of the system clock; supports four-bank operation, burst read/single write operation and LVTTL-compatible multiplexed address inputs.
  • Programmable Latency & Burst CAS latency options of 2 and 3, and selectable burst lengths (1, 2, 4, 8 and full page) with sequential or interleave burst types for flexible performance tuning.
  • Timing & Performance Specified access time of 5 ns and a clock frequency rating of 143 MHz for the -7 variant; write cycle (word/page) time listed at 14 ns for system timing calculations.
  • Refresh & Data Mask Auto and self-refresh support with a 64 ms refresh period (8K cycles) and DQM pins for byte masking during read/write operations.
  • Power & Signaling Datasheet references a JEDEC standard 3.3V power supply; the device supports LVTTL-compatible signaling for multiplexed address operation. (Product specification also lists an internal VoltageSupply value of 2.5V.)
  • Packages & Mounting Available in 54‑pin TSOP II and 54‑ball BGA (BGA54) packages; surface-mount mounting type suitable for compact PCB implementations.
  • Operating Range & Compliance Commercial grade device with an operating temperature range of 0 °C to 70 °C and JEDEC qualification; RoHS‑compliant, Pb‑free construction.

Typical Applications

  • High-bandwidth memory subsystems — Used where synchronous, burst-capable DRAM is required for predictable, clocked data transfer and high throughput.
  • Embedded systems and consumer equipment — Commercial-grade SDRAM option for systems operating within 0 °C to 70 °C that need flexible latency and burst control.
  • Board-level memory expansion — 16-bit parallel interface and common TSOP II/BGA54 packages make it suitable for designers adding expandable volatile memory on PCBs.

Unique Advantages

  • Flexible latency and burst control: CAS latency options (2 & 3) and multiple burst-length modes let designers optimize throughput versus latency.
  • Predictable synchronous operation: Inputs sampled on the positive clock edge enable precise cycle control for deterministic system timing.
  • JEDEC-standard footprint options: Offered in industry-standard TSOP II and BGA54 packages for established manufacturing workflows and footprint reuse.
  • Refresh and masking features: Auto/self-refresh and DQM masking simplify data protection and low-power refresh handling in system designs.
  • Compliance and assembly readiness: JEDEC-qualified, RoHS-compliant and surface-mount packaged for modern production and regulatory requirements.

Why Choose M12L5121632A-7T(2T)?

The M12L5121632A-7T(2T) is positioned for designers who need a JEDEC‑qualified synchronous DRAM device with flexible latency and burst options, predictable clocked operation, and mainstream package choices (TSOP II or BGA54). Its 536.9 Mbit density and 16-bit parallel organization make it suitable for high-bandwidth memory subsystems and board-level expansions where deterministic timing and refresh control are required.

With RoHS-compliant construction and commercial-grade operating range, this ESMT SDRAM balances performance and manufacturability for embedded and consumer applications that rely on reliable, programmable SDRAM behavior.
