Memory IC datasheet and documents for IS66WV51216DBLL-70BLI
Memory IC Overview
The IS66WV51216DBLL-70BLI is an 8Mbit pseudo-static RAM organized as 512K words by 16 bits. It operates within a voltage range of 2.5V to 3.6V and features a 70ns access time. The device utilizes a 48-ball mini BGA package measuring 6mm x 8mm. It supports industrial temperature ranges from -40°C to +85°C and includes three-state outputs with upper and lower byte data control.
Memory IC Feature Summary
- CMOS low power operation with standby current reduction capabilities
- Single power supply design for simplified integration
- Independent upper and lower byte data control via UB and LB pins
Memory IC Applications
- Industrial embedded systems requiring volatile memory
- Automotive electronics operating in standard temperature environments
- Consumer devices utilizing surface mount technology
Memory IC Procurement Notes
Verify the specific suffix BLI confirms the 48-ball mini BGA package and lead-free status. Confirm the 70ns speed grade matches system timing requirements. Ensure the 2.5V-3.6V voltage range aligns with the target board's power rails. Check for RoHS compliance documentation if required by regional regulations.
Memory IC Selection Notes
Select this component when a 16-bit wide interface is necessary for the application architecture. The 48-ball mini BGA form factor suits designs with limited PCB area constraints. Consider the 70ns access speed against processor bus requirements. Verify that the 2.5V-3.6V operating voltage is compatible with the system logic levels.
Memory IC Part Context
This part belongs to the IS66/67WV51216 family of high-speed, ultra-low power pseudo CMOS static RAMs. It shares architectural similarities with the DALL variant but differs in operating voltage and package options. The DBLL series specifically targets applications requiring the 2.5V-3.6V supply range and compact BGA packaging.
Memory IC Replacement Considerations
IS66WV51216DBLL-55BLI offers faster 55ns performance in the same package. IS66WV51216DALL-70BLI provides equivalent speed but requires a lower 1.7V-1.95V supply voltage.
