IS42S32200C1-7BLI

The IS42S32200C1-7BLI is a 64‑Mbit synchronous DRAM (SDRAM) from Integrated Silicon Solution Inc. It implements a quad‑bank, fully synchronous architecture with registered inputs and outputs referenced to the rising edge of the clock.

Designed for 3.3 V systems, this parallel SDRAM targets applications that require burst‑oriented high‑speed transfers, bank interleaving to hide precharge, and operation across an industrial temperature range.

Key Features

• Capacity & Organization — 64 Mbit total capacity organized as 524,288 × 32 × 4 banks (quad‑bank architecture) for parallel data paths and improved throughput.
• High‑speed Synchronous Operation — Rated for 143 MHz clock frequency for the -7 grade with a CAS latency of 3 and access time from clock of 5.5 ns.
• Programmable Burst Control — Supports programmable burst lengths (1, 2, 4, 8, full page) and burst sequence modes (sequential/interleave) to match system transfer patterns.
• Refresh & Power Modes — Auto refresh, self‑refresh and power‑down modes with 4096 refresh cycles every 64 ms to maintain data integrity and reduce power when idle.
• Interface & Signaling — Parallel memory interface with LVTTL‑compatible inputs/outputs and fully synchronous command timing.
• Supply & Timing — Single‑supply operation with VCC range 3.15 V to 3.45 V; programmable CAS latency options and random column address capability allowing one column per clock cycle during burst access.
• Package & Temperature — 90‑ball LFBGA (13 × 8) package and industrial temperature availability with operating range −40 °C to 85 °C.

Typical Applications

• 3.3 V Embedded Memory Subsystems — Acts as synchronous parallel memory for embedded controllers and FPGA/ASIC interfaces requiring burst transfers.
• High‑Speed Data Buffering — Suitable for buffering parallel data streams where burst read/write and bank interleaving improve effective throughput.
• Industrial Systems — Available in industrial temperature grade for systems that must operate between −40 °C and 85 °C.

Unique Advantages

• Quad‑Bank Architecture: Internal four‑bank organization enables concurrent operations and hides row precharge time to improve sustained throughput.
• Flexible Burst Modes: Programmable burst length and sequence let designers optimize transfers for varying access patterns and bus efficiency.
• Synchronous, Predictable Timing: Fully synchronous operation with LVTTL signaling and programmable CAS latency provides deterministic timing for system design.
• Industrial Temperature Range: Specified for −40 °C to 85 °C to support harsher operating environments.
• Compact BGA Package: 90‑ball LFBGA (13 × 8) package reduces board area while supporting high‑speed parallel connections.
• Standard 3.3 V Supply: 3.15 V to 3.45 V supply range and single 3.3 V operation simplify power rail design for legacy 3.3 V systems.
