Overview
The Renesas Electronics Corporation 6116SA25TPGI is a static random-access memory (SRAM) device organized as 32K x 8, providing a total storage capacity of 256 kbit. It operates with an asynchronous parallel interface and features a maximum access time of 25 ns. The component supports a supply voltage range from 4.5 V to 5.5 V, with a maximum power consumption of 145 mA. Designed for through-hole installation, it is housed in a 28-pin PDIP package. The device functions within an operating temperature range of -40°C to +85°C.
Feature Summary
- Provides fully static asynchronous circuitry that eliminates the need for external clocks or periodic refreshing operations during data retention and access.
Applications
- Data buffering in industrial control systems
- Secondary cache memory for embedded processors
- General-purpose volatile data storage in electronic equipment
Procurement Notes
Verify component authenticity due to end-of-life status. Confirm RoHS compliance details via official documentation. Check for obsolescence notifications or alternative sourcing options. Ensure compatibility with existing PCB footprints and voltage requirements before procurement.
Selection Notes
Select this part for applications requiring 256 kbit SRAM with through-hole mounting. Verify that the 25 ns access speed meets system timing requirements. Ensure the operating environment stays within the specified -40°C to +85°C temperature range. Confirm that the 4.5V to 5.5V supply voltage aligns with the design power rails.
Part Context
This component belongs to the 71256SA series of asynchronous SRAMs manufactured by Renesas Electronics. It represents a legacy product line designed for high-reliability memory applications. The specific model utilizes a 28-pin DIP package, distinguishing it from surface-mount variants within the same family.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided documentation. Due to the discontinued status, verify pin-to-pin compatibility with any potential alternatives before implementation.
