Microchip Technology AT27C256R-55RI is a 256Kbit Electrically Programmable Read-Only Memory (EPROM) device featuring a parallel interface. This non-volatile memory component offers an access time of 55 ns and is organized as 32K x 8. The AT27C256R-55RI utilizes OTP (One-Time Programmable) EPROM technology and operates within a supply voltage range of 4.5V to 5.5V. It is packaged in a 28-SOIC (Small Outline Integrated Circuit) format designed for surface mounting, with the specific case measuring 28-SOIC (0.342", 8.69mm Width). The device operates across an industrial temperature range of -40°C to 85°C (TC). This component is prevalent in industrial automation, consumer electronics, and automotive applications where reliable, non-volatile program storage is critical. The AT27C256R-55RI is supplied in a tube.
