The V54C3128(16/80/40)4V(BGA) achieves high speed data transfer rates up to 166 MHz by employing a chip architecture that prefetches multiple bits and then synchronizes the output data to a system clock All of the control, address, data input and output circuits are synchronized with the positive edge of an externally supplied clock. Operating the four memory banks in an interleaved fashion allows random access operation to occur at higher rate than is possible with standard DRAMs. A sequential and gapless data rate of up to 166 MHz is possible depending on burst length, CAS latency and speed grade of the device. s s s s s s s s s Device Usage Chart Operating Temperature Range 0°C to 70°C Package Outline B - Access Time (ns) 6 - Power 8PC - 7PC - 7 - Std. - L - Temperature Mark Blank V54C3128(16/80/40)4V(BGA) Rev. 1.2 September 2001 MOSEL VITELIC V 54 MOSEL-VITELIC MANUFACTURED SYCHRONOUS DRAM FAMILY C = CMOS PROCESS 3.3V, LVTTL, INTERFACE V54C3128(16/80/40)4V(BGA) C 3 128404 V B SPEED 8Mbit x 16:...
