Overview
The AS7C31026B-12TCNTR is a 1-Mbit (64K x 16) asynchronous static random access memory manufactured by Alliance Memory. It operates at a maximum clock speed of 12 ns and supports a supply voltage range of 3.0V to 3.6V. The device utilizes a 44-pin TSOP-II surface-mount package. It functions within a commercial temperature range of 0°C to +70°C. This component provides high-speed parallel data access for embedded systems requiring reliable volatile storage.
Feature Summary
- Asynchronous operation with fast 12ns access time
- Single 3.3V power supply compatibility
- Surface-mount TSOP-II packaging for compact designs
Applications
- Embedded system memory expansion
- Industrial control units
- Consumer electronics data buffering
Procurement Notes
Verify the specific suffix TR indicates tape-and-reel packaging configuration distinct from tray variants. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure the operating temperature range aligns with your system's environmental requirements. Cross-reference the datasheet revision date to guarantee accurate electrical specifications are applied during design validation.
Selection Notes
Select this part when a 64K x 16 organization is required in a 44-pin TSOP-II form factor. Compare against the AS7C31026B-12TCN if tray packaging is preferred instead of reel. Consider the AS7C31025C series if an 8-bit width interface is sufficient for the application. Verify that the 12ns speed meets the timing constraints of the host processor bus.
Part Context
This component belongs to the AS7C31026B family of high-performance SRAM devices. It serves as a volatile memory solution for applications needing rapid read/write cycles without refresh overhead. The TCNTR suffix denotes the commercial temperature grade and tape-and-reel shipping format, differentiating it from industrial or tray-packaged equivalents within the same product line.
Replacement Considerations
The AS7C31026B-12TCN is a pin-compatible alternative packaged in trays rather than tape-and-reel. Both share identical electrical characteristics and functionality. Verify that the change in packaging does not impact automated pick-and-place equipment settings.
