Overview of IS42S32800L-7TL-TR – 256M SDRAM, 3.3V, 8M × 32, 143 MHz
The IS42S32800L-7TL-TR from Integrated Silicon Solution Inc (ISSI) is a 256 Mbit volatile SDRAM organized as 8M × 32. It operates from a 3.0–3.6 V supply, uses an LVTTL memory interface, and is specified for a 143 MHz clock with a 5.4 ns access time.
Housed in an 86-pin TSOP II (86-TFSOP, 0.400" / 10.16 mm width) package and rated for an ambient operating range of 0°C to 70°C, this device is intended for systems requiring external DRAM capacity with a 32-bit data path and defined electrical/thermal parameters.
Key Features
- Memory Core / Organization 256 Mbit SDRAM organized as 8M × 32 (memory format: DRAM) providing a 32-bit data width for system memory needs.
- Performance Clock frequency specified at 143 MHz with an access time of 5.4 ns, suitable for designs matching these timing requirements.
- Voltage Supply Operates from 3.0 V to 3.6 V, compatible with standard 3.3 V logic systems.
- Interface LVTTL memory interface for signal-level compatibility with LVTTL host controllers.
- Package & Mounting 86-TSOP II / 86-TFSOP package (0.400", 10.16 mm width) optimized for surface-mount PCB integration.
- Operating Conditions Ambient operating temperature range specified as 0°C to 70°C (TA).
Typical Applications
- External System Memory Use as external volatile DRAM where 256 Mbit capacity and a 32-bit data path are required.
- Temporary Data Storage Suitable for buffering and temporary data storage in systems that match the device's timing and interface specifications.
- Embedded Memory Expansion Provides additional SDRAM capacity for embedded designs requiring an LVTTL interface and the TSOP II footprint.
Unique Advantages
- Consistent 32-bit Organization: 8M × 32 arrangement enables 32-bit wide transfers to match 32-bit system buses.
- Defined High-Frequency Operation: 143 MHz clock rating combined with a 5.4 ns access time supports lower-latency memory access within specified system designs.
- Standard 3.3 V Supply Range: 3.0–3.6 V supply range aligns with common 3.3 V system power rails for straightforward integration.
- Compact TSOP II Footprint: 86-TSOP II (10.16 mm width) offers a compact surface-mount package for space-constrained PCBs.
- Commercial Temperature Specification: Specified 0°C to 70°C operating range simplifies thermal planning for commercial applications.
