The Advanced Micro Devices AM27C49-55-B3A is a 64Kbit, CMOS UV Erasable Programmable Read-Only Memory (UVPROM) organized as 8K words by 8 bits. Featuring a maximum access time of 55ns, this component operates asynchronously and offers 3-state outputs. It is housed in a 28-lead Ceramic Chip Carrier (CQCC) package with a JEDEC code of S-CQCC-N28. The device supports a supply voltage range of 4.5V to 5.5V and operates across a wide industrial temperature range from -55°C to +125°C. Applications for this type of memory include industrial control systems and legacy equipment requiring non-volatile program storage.
