Memory IC datasheet and documents for IS42S83200B-7TI-TR
Memory IC Overview
The IS42S83200B-7TI-TR is a 256Mb Synchronous DRAM manufactured by ISSI. It features an x8 data bus width and operates at a maximum clock frequency of 143 MHz with a CAS latency of 3. The device utilizes a 54-pin TSOP-II package and supports LVTTL interface signals. Key timing parameters include a 5.4 ns access time from the clock edge. Power supply requirements are specified as 3.0V to 3.6V for both VDD and VDDQ.
Memory IC Feature Summary
- Fully synchronous operation with all signals referenced to the positive clock edge
- Internal bank architecture designed to hide row access and precharge times
- Supports programmable burst lengths including sequential and interleave sequences
- Includes auto-refresh and self-refresh modes for power management
Memory IC Applications
- High-speed data transfer systems using pipeline architecture
- Industrial temperature environment memory applications
- Systems requiring seamless random-access operations via bank interleaving
Memory IC Procurement Notes
Verify the specific suffix '7TI' against official datasheets, as standard documentation lists '7TLI' or '7BL'. Confirm lead-free status and RoHS compliance through manufacturer declarations. Ensure the ordering code matches the exact pin configuration and temperature grade required for the target design.
Memory IC Selection Notes
Select this component for designs requiring 256Mb density in an x8 configuration. The 54-pin TSOP-II package suits surface-mount applications. Verify that the system clock does not exceed 143 MHz for the -7 speed grade. Ensure voltage levels align with the 3.3V LVTTL interface specifications.
Memory IC Part Context
This part belongs to the IS42S83200B series of 256Mb SDRAMs. It shares architectural similarities with the IS42S16160B but differs in data bus width. The series offers options in TSOP-II and BGA packages. It is designed for general-purpose high-speed memory applications within industrial temperature ranges.
