Overview
The AS7C31026B-15JCNTR is a 1 Mbit (64K x 16) asynchronous static random-access memory (SRAM) manufactured by Alliance Memory. It operates within a supply voltage range of 3.0 V to 3.6 V and features a maximum access time of 15 ns. The device is housed in a 44-pin Small Outline J-Lead (SOJ) package with a 400-mil body width, designed for surface-mount technology (SMT). It supports single data rate (SDR) parallel interface operations and functions within a commercial temperature range of 0°C to +70°C.
Feature Summary
- Provides high-speed asynchronous data access with a 15 ns cycle time for efficient system integration.
- Operates on a low-voltage 3.3 V power supply to support energy-efficient electronic designs.
- Utilizes a compact 44-pin SOJ surface-mount package to optimize board space utilization.
Applications
- Embedded systems requiring fast local data storage
- Industrial control equipment with commercial operating environments
- Consumer electronics utilizing 3.3 V logic interfaces
Procurement Notes
Verify the specific suffix 'JCNTR' confirms the tape-and-reel packaging format and industrial/commercial grade designation. Ensure compatibility with 3.3 V logic levels and 44-pin SOJ footprint requirements. Confirm RoHS compliance status through official manufacturer documentation prior to procurement.
Selection Notes
Select this component when a 64K x 16 organization is required with 15 ns speed performance. It is suitable for designs constrained by 3.3 V power supplies and needing surface-mount assembly. Compare against other AS7C31026B variants for differences in access speed or package type if stricter timing or form factors are needed.
Part Context
This part belongs to the AS7C31026B family of 1 Mbit SRAMs from Alliance Memory. The family offers various access speeds and package options, including TSOP and SOJ configurations. The -15 variant specifically denotes the 15 ns access time characteristic, distinguishing it from faster or slower speed grades within the same memory architecture.
Replacement Considerations
Check for AS7C31026B-15JCN (tube package) if reel packaging is not required. Verify pinout compatibility with other 44-pin SOJ SRAMs before substitution.
