Typical applications include boot code storage in industrial controllers, telecom line cards, and test equipment where a mask ROM is too expensive but an EPROM's UV erasure is unnecessary. ## OTP memory: no field updates possible Because this is OTP (one-time programmable), the firmware must be fully validated before programming. There is no UV erasure window and no electrical erase — once written, the content is permanent. This suits production runs where the code is locked down and the same binary goes into every unit. For prototyping or field-updatable designs, a UV EPROM or Flash memory would be the alternative, but those parts are not pin-compatible with this OTP footprint.","metaTitle":"AMD 93Z667DMQB65 OTP ROM, 8K x 8, 65 ns, TTL","metaDescription":"AMD 93Z667DMQB65 OTP ROM, 8K x 8, 65 ns access time, TTL interface, Bulk package.
