Overview of IS42S16160L-7TL-TR – IC DRAM 256MBIT PAR 54TSOP II
The IS42S16160L-7TL-TR from Integrated Silicon Solution Inc. is a 256 Mbit synchronous DRAM (SDRAM) memory device organized as 16M × 16. It provides a synchronous dynamic RAM architecture with a 143 MHz clock frequency and an access time of 5.4 ns for applications requiring mid-range SDRAM performance.
This device operates from a 3.0 V to 3.6 V supply and uses LVTTL signaling for its memory interface. It is supplied in a 54-TSOP II (0.400", 10.16 mm width) package and is specified for an ambient operating temperature range of 0 °C to 70 °C.
Key Features
- Memory Type & Organization Synchronous DRAM (SDRAM) technology with a 16M × 16 organization delivering 256 Mbit total memory capacity.
- Performance 143 MHz maximum clock frequency and a 5.4 ns access time as specified for read/write timing characteristics.
- Interface LVTTL memory interface signaling for control and data lines.
- Voltage Operates from a 3.0 V to 3.6 V supply range, providing compatibility with 3 V-class system rails.
- Package 54-TSOP II (0.400", 10.16 mm width) surface-mount package for compact board-level integration.
- Operating Temperature Specified ambient operating range of 0 °C to 70 °C (TA).
- Manufacturer Supplied by Integrated Silicon Solution Inc. (ISSI).
Unique Advantages
- High-density 256 Mbit capacity: Provides substantial memory in a single 16M × 16 device for designs requiring compact DRAM storage.
