The MR27V6466F is a 64 Mbit One Time Programmable Synchronous Read Only Memory that can be electrically switched between 4,194,304 x 16-bit (word mode) and 2,097,152 x 32-bit (double word mode) by the state of the WORD pin. The MR27V6466F supports high-speed synchronous read operation using a single 3.3 V power supply.
The document describes the MR27V6466F, a 64 Mbit One Time Programmable (OTP) Synchronous Read Only Memory. Its configuration can be electrically switched between 4,194,304 x 16-bit word mode and 2,097,152 x 32-bit double word mode by the state of the WORD pin.
The device supports high-speed synchronous read operation using a single 3.3 V power supply with speeds up to 100 MHz. It features dual electrically switchable configurations and includes burst length options of 4 or 8 cycles, as well as data scramble capabilities.
