The MR27V6466F supports high speed synchronous read operation using a single 3.3 V power supply. Features ON READ - - - - - 3.3 V power supply LVTTL patible with multiplexed address Dual electrically switchable configuration 4M x 16 (word mode) / 2M x 32 (double word mode) All inputs are sampled at the rising edge of the system clock. High speed read operation 100 MHz : CAS Latency = 5, 6 t RCD min: 2 clock cycles 66 MHz : CAS Latency = 5, 6 t RCD min: 2 clock cycles 50 MHz : CAS Latency = 4, 5, 6 t RCD min: 1 clock cycles Burst length (4, 8) Data scramble (sequential, interleave) DQM for data out masking No Precharge operation is required. No Refresh operation is required. No power on sequence is required. Mode register is automatically initialized to the default state after power on. “Row Active” or “Mode Register Set” mand is applicable as the first mand just after power on. Single Bank operation Package: TSOP(2)86-P-400-0.50-K (Product Name : MR27V6466FTA) - - - - - Features ON PROGRAMMING - - 8.0 V programming power supply Programming algorithm is patible with conventional asynchronous OTP. MR27V6466F can be programmed with conventional EPROM programmers. Synchronous Burst read or Static Programming Operation is selected by the state of STO pin. High STO level enables full static programming. (Program, Program Verify, Asynchronous Read) Low STO level enables synchronous burst read. Exclusive 86-pin socket adapters are available from OKI to support programming requirements. The socket...
