Overview of IS42S32160B-7BL-TR – 512Mbit SDRAM (90-LFBGA, 143 MHz)
The IS42S32160B-7BL-TR is a 512Mbit synchronous DRAM device organized as 16M × 32 with an internal quad-bank architecture. It is a fully synchronous parallel SDRAM designed for 3.3V memory systems and optimized for high-speed, pipelined data transfers referenced to the rising edge of the clock.
This device is suited for systems requiring a parallel SDRAM solution with programmable burst control, selectable CAS latency, and support for auto- and self-refresh modes. It is offered in a compact 90-ball LFBGA (13 × 11) package and rated for commercial operation (0°C to +70°C).
Key Features
- Core / Memory Organization 512Mbit SDRAM organized as 16M × 32 (internally configured as 4M × 32 × 4 banks), enabling bank interleaving and hidden row access/precharge.
- Performance Rated for a 143 MHz clock frequency for the -7 speed grade (device family also supports 166 MHz variants); typical access time from clock is 5.4 ns at CAS latency = 3.
- Programmable Burst & CAS Programmable burst lengths (1, 2, 4, 8, full page) and burst sequences (Sequential/Interleave); selectable CAS latency of 2 or 3 clocks.
- Refresh & Power Modes Auto Refresh and Self Refresh supported. Refresh options include 8,192 cycles per 16 ms (A2 grade) or per 64 ms (Commercial/Industrial/A1 grades) as specified in device options.
- Interface LVTTL-compatible I/O with fully synchronous signaling referenced to the positive clock edge; supports random column address every clock cycle during burst access.
- Power Single power supply, nominal 3.3 V with an allowed range of 3.0 V to 3.6 V.
- Package & Temperature 90-LFBGA (13 × 11) supplier device package; commercial operating temperature range 0°C to +70°C (TA).
Typical Applications
- Synchronous memory subsystems — Provides a 512Mbit parallel SDRAM option for systems that require pipelined, clocked DRAM with programmable burst modes.
- Embedded systems — Compact 90-ball LFBGA package and 3.3V supply make it suitable for space-constrained, board-level memory designs operating within the commercial temperature range.
- High-speed buffering — Quad-bank organization and random column addressing every clock enable efficient burst transfers and bank interleaving for buffering and streaming data.
Unique Advantages
- Quad-bank architecture for hidden precharge Internal bank structure hides row access and precharge time to improve sustained burst throughput.
- Flexible timing and bursting Programmable CAS latency (2 or 3 clocks) and multiple burst-length options allow tuning for system timing and throughput requirements.
- Comprehensive refresh options Supports Auto Refresh and Self Refresh with defined refresh-cycle options (8,192 cycles per 16 ms or 64 ms depending on grade) to match system power and data-retention needs.
- Industry-standard LVTTL synchronous interface All signals referenced to the rising clock edge simplify integration into LVTTL-based memory controllers.
- Wide supply tolerance Operates across a 3.0 V to 3.6 V supply range to accommodate typical 3.3 V system rails.
- Compact BGA footprint 90-LFBGA (13 × 11) package delivers high-density memory in a board-friendly form factor.
