Advanced Micro Devices AM27H256-55PC is a 262144-bit, One-Time Programmable Read-Only Memory organized as 32K words by 8 bits. This CMOS device features a maximum access time of 55ns, enabling efficient data retrieval. The AM27H256 series operates asynchronously with common I/O and 3-state output characteristics, supporting parallel interfaces. It is housed in a 28-lead PDIP package with through-hole mounting, featuring a terminal pitch of 2.54mm. The component operates within a temperature range of 0°C to 70°C and requires a supply voltage between 4.5V and 5.5V, with a nominal voltage of 5V. Its typical applications span industrial control systems and consumer electronics where fixed program storage is required. Standby current is rated at 25mA maximum, and active supply current is 50mA maximum. The programming voltage is 12.75V.
