Microchip Technology's AT27HC642-90PC is a 65,536-bit (8K x 8) CMOS One-Time Programmable (OTP) ROM. This component offers a maximum access time of 90 nanoseconds, suitable for applications requiring rapid data retrieval. The memory organization is 8K words by 8 bits, with common I/O. Fabricated using CMOS technology, it operates from a nominal supply voltage of 5V. The AT27HC642-90PC features 3-state outputs for flexible bus interfacing. It is housed in a 24-pin Plastic Dual In-line Package (PDIP) with through-hole mounting and a terminal pitch of 2.54mm. Typical applications include embedded systems, industrial control, and legacy system upgrades where non-volatile code or data storage is essential. Standby current is rated at 35mA maximum, with a maximum operating supply current of 83mA. The operating temperature range is 0°C to 70°C.
