M12L128168A-5BG2S

The M12L128168A-5BG2S is a synchronous DRAM device organized as 4 × 2,097,152 words by 16 bits (134,217,728 bits). It implements a parallel SDRAM architecture with four internal banks and supports JEDEC-standard 3.3 V operation for use in synchronous, clocked memory subsystems.

Designed for high-data-rate memory system applications, this device offers programmable burst lengths and latencies and supports common SDRAM features such as auto/self refresh and data masking, enabling integration into a range of commercial designs that require predictable, clocked memory behavior.

Key Features

• Memory Organization  134,217,728-bit SDRAM organized as 2M × 16 with four banks to support bank-interleaving and efficient memory access.
• Clock and Timing  Specified for 200 MHz operation with an access time of 4.5 ns and a write cycle time (word/page) of 10 ns, providing defined timing for synchronous systems.
• JEDEC Standard 3.3 V Supply  Operates from 3.0 V to 3.6 V in accordance with JEDEC power requirements for SDRAM devices.
• Burst and Latency Options  Programmable burst lengths (1, 2, 4, 8, full page) and CAS latencies of 2 and 3 to match system throughput and access patterns.
• Synchronous Interface  All inputs are sampled on the positive edge of the system clock; supports LVTTL-compatible multiplexed addresses and parallel DQ[0:15] data lines.
• Bank and Addressing Controls  Bank address pins (BA0, BA1), multiplexed row/column addressing (A0–A11), and standard control signals (RAS, CAS, WE, CS, CKE) for typical SDRAM command sequences.
• Data Integrity and Refresh  DQM data masking, auto and self-refresh capability, and a 64 ms refresh period (4K cycle) to maintain stored data.
• Separate Output Power  VDDQ/VSSQ pins isolate data output power and ground for improved noise immunity on the output buffers.
• Commercial Grade and Packaging  Commercial operating temperature 0 °C to 70 °C and supplied in a 54-ball FBGA package (54-FBGA) with surface-mount mounting.
• RoHS Compliant  Device is RoHS compliant and supplied Pb-free as part of the M12L128168A series offerings.

Typical Applications

• High-bandwidth memory subsystems  Integration into systems that require synchronous, clocked DRAM for predictable high-rate data access patterns.
• Board-level memory expansion  Use as a parallel SDRAM component for designs needing 2M × 16 organization and standard SDRAM control signals.
• Embedded systems with parallel SDRAM interfaces  Suited for commercial embedded designs operating within 0 °C to 70 °C that require JEDEC-compatible SDRAM behavior.

Unique Advantages

• Standard JEDEC 3.3 V interface: Simplifies integration with existing 3.3 V SDRAM controllers and system designs.
• Flexible burst and latency settings: Programmable burst lengths and CAS latencies allow tuning for different access patterns and system throughput requirements.
• Four-bank architecture: Enables bank interleaving and improved utilization of internal memory resources for sustained data transfers.
• Isolated output power (VDDQ): Improves noise immunity on data outputs, aiding signal integrity in board-level designs.
• Auto and self-refresh support: Simplifies refresh management in systems that require low-power standby or predictable refresh behavior.
• Compact FBGA packaging: 54-ball FBGA provides a small, surface-mount footprint suitable for compact commercial designs.
