Memory IC datasheet and documents for 7028L20PFI
Memory IC Overview
The IDT7028L20PFI is a 1Mbit (128K x 8) dual-port static RAM manufactured by Renesas Electronics. It features asynchronous parallel interfaces with a 20 ns access time. The device operates on a single 5V supply within the 4.5V to 5.5V range and supports surface-mount installation in a 100-TQFP package. It is designed for high-speed data buffering and protocol conversion applications.
Memory IC Feature Summary
- Dual-port architecture enabling independent simultaneous access from two processors
- Asynchronous operation compatible with various system clock speeds
- Single 5V power supply requirement for simplified design
Memory IC Applications
- High-speed data buffering in communication systems
- Protocol conversion between different bus standards
- Cache memory implementation in embedded controllers
Memory IC Procurement Notes
Verify component authenticity through authorized distributors due to end-of-life status. Confirm RoHS compliance requirements as original specifications may not meet current environmental directives. Validate package integrity upon receipt to ensure pin alignment matches the 100-TQFP footprint. Review latest datasheets for any manufacturing changes or obsolescence notices before finalizing procurement plans.
Memory IC Selection Notes
Select this component when dual-port functionality is required for 1Mbit capacity. Ensure system voltage aligns with the 5V specification. Consider the 100-TQFP package constraints for PCB layout. Evaluate thermal management needs given the operating temperature range of -40°C to +85°C. Compare against newer generations if long-term availability is critical.
Memory IC Part Context
This part belongs to the IDT7028 series of dual-port SRAMs. It provides non-volatile-like speed with volatile storage characteristics. The series is widely used in industrial and telecommunications equipment requiring fast, reliable data exchange between disparate processing units without complex arbitration logic.
Memory IC Replacement Considerations
Public confirmed substitute part numbers are not available in the provided documentation. Consult manufacturer resources for direct replacements or evaluate equivalent dual-port SRAMs with matching capacity and interface timing.
