MT48LC8M32B2TG-7 IT TR

The MT48LC8M32B2TG-7 IT TR is a 256 Mbit synchronous DRAM organized as 8M × 32 with four internal banks and a parallel memory interface. It implements a fully synchronous, pipelined architecture with PC100 functionality and programmable burst lengths for flexible data transfers.

This device targets systems that require a 256 Mbit parallel SDRAM in a compact 86-pin TSOP II package and operation across industrial temperature ranges, providing selectable CAS latencies, auto-refresh and self-refresh support, and LVTTL-compatible I/O.

Key Features

• Core Architecture  Fully synchronous SDRAM with internal pipelined operation; all signals are registered on the positive edge of the system clock and internal banks help hide row access and precharge timing.
• Memory Organization  8M × 32 organization (2M × 32 × 4 banks) for a total of 256 Mbit of DRAM capacity.
• Performance & Timing  -7 speed grade: 143 MHz clock frequency with 6.0 ns access time (CL = 3); supports CAS latency options 1, 2, and 3 and programmable burst lengths of 1, 2, 4, 8 or full page.
• Power  Single supply operation at +3.3 V with a specified range of 3.0 V to 3.6 V.
• Refresh & Low-Power Modes  Supports Auto Refresh, Self Refresh and Concurrent Auto Precharge; 64 ms, 4,096-cycle refresh with 15.6 μs per row refresh interval is specified.
• I/O Compatibility  LVTTL-compatible inputs and outputs with parallel memory interface and standard SDRAM command set (READ, WRITE, AUTO PRECHARGE, etc.).
• Package & Temperature  86-pin TSOP II (400 mil / 10.16 mm width) package; industrial operating temperature range of −40 °C to +85 °C (TA) for the IT grade.
• Additional Timing  Write cycle time (word page) specified at 14 ns; timing parameters and commands follow standard SDRAM definitions from the datasheet.

Unique Advantages

• Deterministic synchronous operation: Fully synchronous design with registered inputs/outputs provides predictable timing tied to the system clock.
• Flexible data transfer modes: Programmable burst lengths and CAS latency options allow tuning of throughput and latency for different access patterns.
• Industrial temperature support: −40 °C to +85 °C rating (IT) enables use in temperature-demanding environments.
• Standard 3.3 V supply: Single-supply operation at 3.0–3.6 V simplifies power architecture in systems using legacy SDRAM voltages.
• Compact board footprint: 86-pin TSOP II (400 mil) package provides a high-density mount option for space-constrained designs.
• Robust refresh and low-power modes: Auto Refresh and Self Refresh support with 4,096-cycle refresh ensures data retention and predictable refresh behavior.
