The MR27V852E is an 8 Mbit electrically One Time Programmable Read-Only Memory (One Time PROM) with page mode. Its configuration can be electrically switched between 524,288-word × 16-bit and 1,048,576-word × 8-bit by the state of the BYTE pin. The MR27V852E supports high speed asynchronous read operation using a single 3.3V power supply.
The MR27V852E is a high-speed asynchronous Read-Only Memory (ROM) that supports a single 3.3V power supply. Its configuration can be electrically switched between 524,288-word × 16-bit and 1,048,576-word × 8-bit modes by the state of the BYTE pin.
The device features page mode operation with a page size of either 8-word x 16-Bit or 16-word x 8-Bit. It offers maximum access times of 100 ns for random access and 30 ns for page access, making it suitable for commercial applications such as office automation and communication equipment.
