Overview
The AS6C8016-55ZINTR is a 4 Mbit (256K x 16) asynchronous static random-access memory manufactured by Alliance Memory. It operates within a voltage range of 2.7 V to 5.5 V and features a maximum access time of 55 ns. The device supports parallel interface communication and draws a maximum supply current of 60 mA. Designed for surface-mount applications, it is housed in a TSOP-II-44 package. The component functions reliably across an extended industrial temperature range from -40°C to +85°C.
Feature Summary
- Supports wide voltage operation from 2.7V to 5.5V
- Provides fast 55ns asynchronous access speed
- Utilizes compact TSOP-II-44 surface mount packaging
Applications
- Industrial control systems requiring robust memory storage
- Consumer electronics with varying power supply constraints
- Embedded computing modules needing high-speed data buffering
Procurement Notes
Verify the specific suffix ZINTR against official datasheets to confirm RoHS compliance and lead-free status. Ensure the ordering code matches the exact pinout and package dimensions required for your PCB layout. Confirm availability through authorized distributors as manufacturing statuses may change. Cross-reference the manufacturer part number to avoid confusion with similar variants in the AS6C8016 series.
Selection Notes
Select this component when a 256K x 16 organization is required for data width compatibility. The 55ns access time suits general-purpose processing tasks without strict high-frequency demands. The wide voltage range allows integration into systems powered by either 3.3V or 5V rails. The TSOP-II-44 package offers a balance between pin count and board space efficiency for dense designs.
Part Context
This part belongs to the AS6C8016 family of asynchronous SRAM devices. It shares architectural similarities with other members like the AS6C8016-55BIN but differs in package type and compliance specifications. The family targets applications needing non-volatile-like retention without the complexity of flash programming. It complements microcontrollers and DSPs in embedded architectures.
Replacement Considerations
Check for direct substitutes such as the AS6C8016-55BIN if the TBGA-48 package is acceptable. Verify electrical compatibility before swapping packages to ensure signal integrity remains unaffected.
