Memory IC datasheet and documents for 7025S55PFI
Memory IC Overview
The Renesas Electronics Corporation 7025S55PFI is a dual-port asynchronous SRAM IC with a storage capacity of 64Kb, organized as 4K x 16. It features parallel interface and a 55 ns access time. The device operates on a 4.5V to 5.5V supply voltage within an industrial temperature range of -40°C to 85°C. It is housed in a 100-TQFP (14x14) surface-mount package.
Memory IC Feature Summary
- Dual-port architecture enabling simultaneous independent access from two ports
- Asynchronous operation for flexible system integration
- Parallel interface supporting standard memory bus protocols
Memory IC Applications
- High-speed data buffering in embedded systems
- Cache memory implementation in microcontroller applications
- Data logging and temporary storage in industrial control units
Memory IC Procurement Notes
Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm the specific suffix PFI matches the required 100-TQFP package and industrial temperature grade. Check for recent production change notices regarding pinout or electrical specifications before finalizing procurement plans.
Memory IC Selection Notes
Select this component when a 64Kb dual-port configuration is required rather than the common 128Kb variant. Ensure the 55 ns speed meets system timing requirements. Verify that the 100-pin TQFP footprint fits the PCB layout constraints compared to other available packages like PLCC.
Memory IC Part Context
This part belongs to the Renesas 7025 series of dual-port static RAMs. While many variants in this family offer 128Kb density, the 7025S55PFI specifically provides 64Kb capacity. It shares architectural similarities with other asynchronous dual-port devices but is distinguished by its specific density and package type.
Memory IC Replacement Considerations
Direct substitutes include other 7025 series parts with matching 64Kb density and 55 ns speed, such as the 7025S55JG8, provided the package difference between TQFP and PLCC is accommodated in the design.
