IS45S32400E-7BLA2-TR

The IS45S32400E-7BLA2-TR is a 128 Mbit synchronous DRAM (SDRAM) organized as 4M × 32 with a quad-bank architecture and pipeline operation. It provides high-speed, fully synchronous parallel memory suitable for systems that require a dedicated 128 Mbit SDRAM device with programmable burst and latency options.

Designed for systems operating with a 3.0 V – 3.6 V supply and a clock frequency up to 143 MHz (CL = 3), this device supports features such as internal bank management, programmable burst lengths, auto and self refresh modes, and a compact 90‑ball TF‑BGA package.

Key Features

• Core Architecture  Quad-bank SDRAM configured as 1M × 32 × 4 banks to enable internal bank interleaving and row access/precharge hiding.
• Memory Organization & Capacity  128 Mbit total capacity organized as 4M × 32.
• SDRAM Timing & Performance  Fully synchronous operation with clock-referenced inputs/outputs; supports 143 MHz operation with CAS latency = 3 and an access time from clock of 5.4 ns (CL = 3).
• Programmable Burst & Latency  Programmable burst lengths (1, 2, 4, 8, full page) and burst sequencing (Sequential/Interleave); CAS latency programmable to 2 or 3 clocks.
• Refresh & Low Power Modes  Supports Auto Refresh (CBR) and Self Refresh; refresh cycle options include 4096 refresh cycles per 16 ms (A2 grade) or 64 ms (Commercial/Industrial/A1 grade) as specified in device options.
• Interface  LVTTL-compatible signals with parallel memory interface and support for random column address every clock cycle and burst termination commands (burst stop, precharge).
• Power  Single power supply range of 3.0 V – 3.6 V (3.3 V ±0.3 V operation as specified in datasheet).
• Package & Temperature  90‑ball TF‑BGA (8 × 13) package with specified operating temperature range from -40°C to +105°C (TA).

Typical Applications

• System Memory Expansion  Used as on‑board parallel SDRAM for systems that require an isolated 128 Mbit memory device with programmable burst and latency control.
• Embedded Memory Subsystems  Suitable for embedded designs needing synchronous parallel DRAM with self-refresh and auto-refresh capabilities.
• High‑Speed Buffering  Employed where pipeline architecture and quad‑bank operation support continuous high‑speed data transfers and random column access every clock cycle.

Unique Advantages

• Flexible Timing Control: Programmable CAS latency (2 or 3 clocks) and selectable burst lengths allow designers to tune throughput and latency to match system timing requirements.
• High‑Speed Synchronous Operation: Supports up to 143 MHz operation (CL = 3) with a 5.4 ns access time from clock, enabling responsive read/write bursts in synchronous systems.
• Robust Refresh Options: Auto and self refresh modes with device options for 4K refresh cycles per 16 ms or 64 ms provide flexibility for different refresh timing requirements.
• Compact, Board‑Level Package: 90‑TFBGA (8 × 13) ball array minimizes PCB footprint while supporting high‑density memory integration.
• Wide Supply Range: Operates across 3.0 V – 3.6 V, accommodating standard 3.3 V memory system rails.
• Wide Operating Temperature: Specified -40°C to +105°C (TA) for designs that require extended temperature operation.
