MT48LC32M8A2P-75 IT:D

The MT48LC32M8A2P-75 IT:D is a 256 Mbit SDR SDRAM device organized as 32M × 8 with a parallel memory interface in a 54-pin TSOP II (400 mil) package. It targets applications that require synchronous DRAM with PC100/PC133 timing compliance, offering standard SDRAM features for burst transfers and internal banked operation.

This device delivers 133 MHz clock operation with a single 3.3 V ±0.3 V supply and supports industrial ambient operation from −40 °C to +85 °C, making it suitable for designs needing a compact, parallel SDRAM memory solution in a TSOP II footprint.

Key Features

• Core / Memory  256 Mbit SDR SDRAM organized as 32M × 8 with four internal banks to improve efficient row access and precharge handling.
• Performance & Timing  PC100- and PC133-compliant operation with a rated clock frequency of 133 MHz and an access time of 5.4 ns; timing options include 3-3-3 and 2-2-2 CAS/RCD/RP configurations per the datasheet.
• Burst and Refresh Functions  Programmable burst lengths (1, 2, 4, 8, or full page), auto precharge, auto refresh and a self-refresh mode (self-refresh not available on AT devices); supports 8192-cycle refresh.
• Interface & I/O  Parallel memory interface with LVTTL-compatible inputs and outputs and fully synchronous operation where all signals are registered on the positive edge of the system clock.
• Power  Single-supply operation at 3.3 V ±0.3 V (3.0 V to 3.6 V) to match standard SDRAM system rails.
• Package & Temperature  54-pin TSOP II (0.400", 10.16 mm width) plastic package; industrial operating temperature range of −40 °C to +85 °C (TA) for extended-environment deployments.

Typical Applications

• PC memory subsystems  Use in systems requiring PC100/PC133-compliant SDRAM timing and standard SDRAM functionality.
• Industrial embedded systems  Suitable for embedded designs that need parallel SDRAM operation across an industrial temperature range (−40 °C to +85 °C).
• Legacy and replacement designs  Fits designs requiring a compact 54-pin TSOP II SDRAM package with a 32M × 8 organization and standard 3.3 V supply.

Unique Advantages

• Industry-standard timing compatibility: PC100/PC133 compliance and multiple CAS/RCD/RP timing options simplify integration into systems designed around these standards.
• Flexible burst operation: Programmable burst lengths and internal pipelined operation allow column address changes every clock cycle for efficient data throughput.
• Compact TSOP II packaging: The 54-pin TSOP II (400 mil) footprint offers a dense, board-friendly form factor for space-constrained designs.
• Industrial temperature support: Rated for −40 °C to +85 °C ambient operation, enabling use in a wider range of environmental conditions.
• Single 3.3 V supply: Standard 3.0–3.6 V supply range aligns with common SDRAM power rails for straightforward board-level power design.
