Overview
The AS7C164A-15PCN is a 64 Kbit (8K x 8) asynchronous static random-access memory manufactured by Alliance Memory. It operates within a supply voltage range of 4.5 V to 5.5 V and features a maximum access time of 15 ns. The device is housed in a 28-pin Skinny Plastic Dual In-Line Package (PDIP). It supports parallel interface communication and is rated for commercial operating temperatures between 0°C and +70°C. Maximum power consumption current is specified at 140 mA.
Feature Summary
- Asynchronous parallel SRAM architecture providing non-synchronized data access
- Single 5V power supply operation compatible with standard logic levels
- Robust plastic dual in-line package design suitable for through-hole mounting
Applications
- Embedded systems requiring volatile data storage
- Industrial control units with commercial temperature constraints
- General-purpose microcontroller memory expansion
Procurement Notes
Verify the specific suffix PCN confirms the 28-pin PDIP package and commercial temperature grade. Ensure the 15 ns speed bin matches system timing requirements. Confirm RoHS compliance status if restricted substances are mandated. Check humidity sensitivity level for proper handling during assembly processes.
Selection Notes
Select this component when a 64 Kbit capacity is sufficient for the application. The 15 ns access time suits moderate-speed processing needs. The PDIP form factor is ideal for prototyping or legacy board designs requiring through-hole technology. Verify that the 5V logic levels align with the host processor I/O specifications.
Part Context
This part belongs to the AS7C164A series of high-speed CMOS SRAMs. It serves as a compact, low-power memory solution for embedded applications. The series offers various package options including SOJ and DIP variants. It provides reliable data retention without refresh cycles typical of DRAM technologies.
Replacement Considerations
AS7C164A-15JIN: Industrial temperature grade (-40°C to +85°C), SOJ-28 package. AS7C164A-15TCN: Commercial temperature, TSOP-II package. Verify pin compatibility and thermal ratings before substitution.
