The Advanced Micro Devices AM27C49-55LCB is a 64Kbit (8K x 8) CMOS UV Programmable Read-Only Memory (UVPROM) device featuring an asynchronous operating mode. This component offers a maximum access time of 55ns and operates from a supply voltage range of 4.5V to 5.5V, with a nominal supply voltage of 5V. The AM27C49 series memory IC is housed in a 28-lead ceramic chip carrier (CQCC28) package with a square shape and metal-sealed cofired construction. Its 3-state outputs enable efficient bus sharing in various applications. This UVPROM is suitable for use in industrial control, telecommunications, and legacy system designs requiring non-volatile code storage.
