AS7C164A-15JCN

Overview

The AS7C164A-15JCN is a 64 Kbit Static Random Access Memory (SRAM) manufactured by Alliance Memory. It features an organized capacity of 8K x 8 bits with a maximum access time of 15 ns. The device operates on a parallel interface and requires a supply voltage between 4.5 V and 5.5 V, with a maximum power consumption of 140 mA. It is housed in a 28-pin Small Outline J-Lead (SOJ) package designed for surface mount technology. The component supports commercial temperature ranges from 0°C to +70°C.

Feature Summary

• Provides non-volatile data retention without requiring refresh cycles typical of dynamic memory.
• Supports high-speed asynchronous read and write operations via a standard parallel interface.
• Designed for surface-mount integration using a compact 28-pin SOJ form factor.

Applications

• Embedded systems requiring fast local data storage
• Industrial control units needing reliable buffer memory
• Consumer electronics utilizing 5V logic interfaces

Procurement Notes

Verify the specific suffix 'JCN' against the manufacturer's current datasheet to confirm pinout compatibility and RoHS status. Ensure the procurement channel provides original packaging documentation. Confirm that the 28-pin SOJ package matches the target PCB footprint requirements before finalizing orders.

Selection Notes

Select this component when a 64 Kbit capacity with 15 ns speed is required within a 5V logic environment. The SOJ-28 package suits applications where space constraints allow for small outline leads. Consider the 140 mA active current draw for power budgeting in battery-operated or low-power designs.

Part Context

This part belongs to the AS7C164 series of SRAM devices. It serves as a general-purpose memory solution for microcontroller-based systems. The 15 ns speed class balances performance with power efficiency for commercial-grade applications.

Replacement Considerations

Check for direct pin-compatible alternatives within the same speed and voltage class. Verify if newer revisions of the AS7C164 series offer updated packaging options while maintaining electrical equivalence.
