Overview of IS42S32800L-7BL-TR – 256M SDRAM, 3.3V, 8M×32, 143 MHz
The IS42S32800L-7BL-TR by ISSI is a 256 Mbit volatile SDRAM device organized as 8M × 32. It implements synchronous DRAM architecture with a specified clock frequency of 143 MHz and an access time of 5.4 ns.
Configured for 3.0 V to 3.6 V operation (nominal 3.3 V) and supplied in a 90-TFBGA (8×13) package, this device is characterized for an ambient operating range of 0°C to 70°C.
Key Features
- Memory Core / Organization 256 Mbit density arranged as 8M × 32 bits (DRAM, volatile).
- Performance Synchronous operation with a 143 MHz clock frequency and a specified access time of 5.4 ns.
- Voltage Operates from 3.0 V to 3.6 V (3.3 V nominal).
- Interface LVTTL memory interface signaling.
- Package 90-TFBGA package (8×13) as the supplier device package.
- Temperature Range Rated for ambient operation from 0°C to 70°C (TA).
- Memory Format Standard DRAM memory format for synchronous memory applications.
Unique Advantages
- High memory density: 256 Mbit capacity in an 8M × 32 organization provides substantial onboard DRAM capacity for memory-intensive tasks.
- Defined timing performance: 143 MHz clocking and a 5.4 ns access time deliver clear, specified timing behavior for system timing budgets.
- Standard 3.3 V supply range: 3.0 V to 3.6 V operation aligns with common 3.3 V system power rails.
- Compact BGA footprint: 90-TFBGA (8×13) package minimizes board area for higher density layouts.
- LVTTL interface support: Built for compatibility with LVTTL signaling environments.
- Commercial temperature rating: 0°C to 70°C specification matches common commercial and industrial ambient requirements.
