MR27V3266D

1 Semiconductor MR27V3266D 2M x16 / 1M x32 Synchronous OTP ROM DESCRIPTION The MR27V3266D is a 32Mbit One Time Programmable Synchronous Read Only Memory whose configuration can be electrically switched between 2,097,152 x16bit(word mode) and 1,048,576 x32bit(double word mode) by the state of the /WORD pin. The MR27V3266D supports high speed synchronous read operations using a single 3.3V power supply. FEATURES ON READ 3.3V power supply LVTTL compatible with multiplexed address Dual, electrically switchable configurations 2M x16(word mode) / 1M x32(double word mode) All inputs are sampled at the rising edge of the system clock High speed read operation 66MHz : CAS Latency=5 tRCDmin=2 Burst Length (4, 8) Data scramble (sequential, interleave) 50MHz : CAS Latency=4, 5 tRCDmin=1 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" command to read data is applicable as the first command just after power on. Single Bank operation Package : TSOP II 86-P-400-0.50-K - - FEATURES ON PROGRAMMING 9.75V programming Power supply Programming algorithm is compatible with conventional asynchronous 32M OTP. MR27V3266D can be programmed with conventional EPROM programmers. Synchronous Burst read or Static Programming Operation are selected by the state of STO pin. H...
