27S25AJC

Overview

The AM27S25AJC is a one-time programmable read-only memory (OTP ROM) manufactured by Rochester Electronics, LLC. It features a memory organization of 512 words by 8 bits, providing a total density of 4096 bits. The device utilizes bipolar technology and operates in synchronous mode with parallel interface capabilities. It is housed in a 24-pin plastic dual in-line package (PDIP-24). Electrical specifications include a nominal supply voltage of 5 V, with an operating range from 4.75 V to 5.25 V. The component supports a maximum operating temperature of 75 °C.

Feature Summary

Provides non-volatile storage via one-time programmable architecture
Operates synchronously with parallel data access
Utilizes standard bipolar manufacturing technology

Applications

Embedded system firmware storage
Microcontroller program memory replacement
Industrial control logic implementation

Procurement Notes

Verify the specific suffix 'JC' against official datasheets to confirm package type and temperature grade accuracy. Ensure the OTP status is understood as permanent; data cannot be altered after programming. Confirm lead times and availability directly with authorized distributors, as this is a specialized legacy component.

Selection Notes

Select this component when a fixed, non-volatile 512x8 memory solution is required for synchronous applications. Verify that the 5V bipolar power requirements align with the target system design. Consider the DIP-24 package constraints for PCB layout and ensure the 75 °C thermal limit meets environmental conditions.

Part Context

This part belongs to the AM27S25 series of OTP ROMs. These devices are designed to replace mask-programmed ROMs in systems requiring field customization. The series offers a cost-effective alternative to EPROMs where reprogramming is not necessary, providing permanent data retention without the need for UV erasure.

Replacement Considerations

Check for direct pin-compatible substitutes within the same OTP ROM family. Verify if upgraded versions with extended temperature ranges or different packaging options are available from the manufacturer.
