MT48LC8M16A2P-7E IT:L TR

The MT48LC8M16A2P-7E IT:L TR is a 128 Mbit volatile SDRAM device organized as 8M × 16 with four internal banks. It is a fully synchronous parallel DRAM optimized for systems requiring PC100/PC133-class SDRAM operation, offering a compact 54-pin TSOP II package and industrial operating temperature range.

Key Features

• Memory Architecture  128 Mbit memory organized as 8M × 16 with four internal banks, suitable for parallel SDRAM subsystems.
• SDRAM Technology  Fully synchronous DRAM with internal pipelined operation and programmable burst lengths (1, 2, 4, 8, or full page); all signals registered on the positive edge of the system clock.
• Performance  PC100- and PC133-compliant; specified clock frequency up to 133 MHz and access time of 5.4 ns for the -7E speed grade; programmable CAS latency options indicated in the datasheet.
• Refresh and Auto Modes  Supports Auto Precharge (including concurrent auto precharge), Auto Refresh, and Self Refresh modes with a 64 ms, 4,096-cycle refresh scheme.
• Interface and I/O  Parallel memory interface with LVTTL-compatible inputs and outputs; internal banks hide row access/precharge and column address can be changed every clock cycle.
• Power  Single-supply operation at +3.3 V (specified 3.0 V to 3.6 V).
• Package and Mounting  54-pin TSOP II (0.400", 10.16 mm width) plastic package for surface-mount designs; supplier device package listed as 54-TSOP II.
• Operating Temperature  Industrial temperature range: −40 °C to +85 °C (TA).

Typical Applications

• PC100/PC133 systems  Memory for systems requiring PC100 or PC133-compliant SDRAM operation, leveraging the device's 133 MHz clock capability and 5.4 ns access time.
• Industrial-temperature equipment  Use in equipment operating across −40 °C to +85 °C where a 128 Mbit SDRAM in a 54‑TSOP II package is required.
• Parallel SDRAM subsystems  Integration into parallel memory subsystems that benefit from LVTTL-compatible I/Os, programmable burst lengths, and internal bank architecture.

Unique Advantages

• Verified PC100/PC133 compatibility:  Device is PC100- and PC133-compliant per datasheet, supporting established SDRAM timing profiles.
• Compact surface-mount package:  54-pin TSOP II reduces board area while providing a standard footprint for parallel SDRAM implementations.
• Industrial temperature support:  Rated for −40 °C to +85 °C, enabling deployment in temperature-critical applications.
• Flexible burst and refresh modes:  Programmable burst lengths, Auto Precharge, Auto Refresh, and Self Refresh modes simplify memory control and power management.
• Standard 3.3 V supply:  Operates from 3.0 V to 3.6 V, matching common system power rails.
• Pipelined internal operation:  Internal pipelining and multi-bank architecture allow column address changes every clock cycle to improve throughput in burst transfers.
