Overview
The AS7C31025C-12TINTR is a 1 Mbit (128K x 8) asynchronous static random-access memory manufactured by Alliance Memory. It operates within a voltage range of 3.0 V to 3.6 V and features a maximum access time of 12 ns. The device utilizes a parallel interface and supports Single Data Rate (SDR) storage. It is housed in a SOJ-32 surface-mount package and is designed for industrial temperature operation, ranging from -40°C to +85°C. Maximum power consumption is specified at 150 mA.
Feature Summary
- Asynchronous parallel interface for standard data transfer operations
- Industrial-grade operational temperature range for robust performance
- Single Data Rate (SDR) memory architecture
Applications
- Industrial control systems requiring reliable volatile memory
- Embedded applications operating under strict thermal conditions
- Data buffering in high-speed parallel processing circuits
Procurement Notes
Verify the specific suffix 'IN' against official datasheets to confirm the SOJ-32 package and industrial temperature rating. Confirm RoHS compliance status directly with the manufacturer or authorized distributors. Check current lifecycle status as availability may be limited due to production schedules.
Selection Notes
Select this component when a 128K x 8 organization is required with 12 ns speed at 3.3V logic levels. Ensure the design accommodates the SOJ-32 footprint and industrial temperature constraints. Compare against commercial variants if extended temperature ranges are not necessary for the target application environment.
Part Context
This part belongs to the AS7C31025C series of 1 Mbit SRAMs. It shares core specifications with other variants but differs in packaging and temperature grade. The 'C' designation typically indicates the 3.3V supply voltage family, distinguishing it from 5V counterparts like the AS7C1025 series.
Replacement Considerations
Direct substitutes include AS7C31025C-12TIN for tube packaging or AS7C31025C-12TCN for TSOP packages. Verify pin compatibility and electrical parameters before swapping.
