The AT27C512R-90RC is an IC component produced by Atmel Corporation. It is a 512K (kilobit) read-only memory (ROM) chip with a 90ns access time. Here are the key features and specifications of the AT27C512R-90RC:
1. High Capacity: It has a storage capacity of 64K x 8 bits, which amounts to a total of 512K bits. This allows it to store a considerable amount of data or program code.
2. Read-Only Memory: AT27C512R-90RC is a ROM chip, meaning that it can only be read. It is not possible to write or modify the contents of the memory after programming.
3. Fast Access Time: The access time of 90ns indicates the time required for the processor or other devices to access the data stored in the chip. This chip provides fast access to the stored information.
4. High-Speed Operation: With an operating voltage range between 4.5V to 5.5V, it supports high-speed operation. The chip requires standard TTL input and output levels.
5. Low Power Consumption: The AT27C512R-90RC is designed to minimize power consumption by utilizing CMOS technology. It is suitable for power-sensitive applications
