MT48LC4M16A2TG-7E IT:G TR

The MT48LC4M16A2TG-7E IT:G TR is a 64 Mbit synchronous DRAM organized as 4M × 16 with a parallel memory interface in a 54‑pin TSOP II package. It implements fully synchronous operation with internal pipelined architecture and multiple internal banks to optimize row/column access performance.

Designed for systems that require PC133-speed SDRAM behavior and industrial temperature operation, this device provides programmable burst lengths, auto/precharge and refresh modes, and LVTTL‑compatible I/O for straightforward integration into parallel memory subsystems.

Key Features

• Core / Architecture  Fully synchronous DRAM with internal pipelined operation and four internal banks to hide row access/precharge and support column address changes every clock cycle.
• Memory Organization & Capacity  64 Mbit capacity organized as 4M × 16 with four banks (1M × 16 × 4 banks).
• Performance  PC66-, PC100- and PC133-compliant timing options; specified clock frequency 133 MHz and access time 5.4 ns. Programmable burst lengths: 1, 2, 4, 8, or full page.
• Data Integrity & Refresh  Auto Refresh, Concurrent Auto Precharge, Auto Precharge and Self Refresh modes with 64 ms / 4,096-cycle refresh support to maintain data in volatile memory.
• Interface  Parallel memory interface with LVTTL-compatible inputs and outputs for direct system interfacing.
• Power  Single +3.3 V ±0.3 V power supply (specified voltage range 3.0 V to 3.6 V) supporting standard SDRAM power domains.
• Package & Mounting  54-pin TSOP II (400 mil / 10.16 mm width) surface-mount package for compact board-level memory implementation.
• Operating Range  Industrial operating temperature range: −40 °C to +85 °C (TA), suitable for temperature‑sensitive applications.

Typical Applications

• Industrial Embedded Systems  Memory expansion in industrial controllers and embedded devices benefiting from the −40 °C to +85 °C operating range.
• Parallel SDRAM Subsystems  On‑board parallel DRAM for designs that require a 4M × 16 memory organization and PC133-compatible timing.
• Legacy and Replacement Designs  Replacement or refurbishment of systems using 54‑pin TSOP II parallel SDRAM footprints and LVTTL signaling.

Unique Advantages

• PC133‑class timing in a compact package: 133 MHz clock support and 5.4 ns access time combine performance with a 54‑pin TSOP II footprint.
• Flexible burst and refresh control: Programmable burst lengths plus Auto/Concurrent Auto Precharge and Self Refresh modes simplify memory management and timing control.
• Industrial temperature support: Rated for −40 °C to +85 °C (TA), enabling deployment in temperature‑sensitive environments.
• Standard power domain: Operates from a single +3.3 V ±0.3 V supply (3.0 V to 3.6 V), matching common system rails.
• LVTTL‑compatible I/O: Direct interfacing with LVTTL logic levels reduces interface translation requirements.
