Description
The VB78L05S is an electronic component model categorized as an IC chip. Specifically, it is the V54C3128(16/80/40)4V(BGA), a four-bank Synchronous DRAM. It is organized as 4 banks x 2Mbit x 16, 4 banks x 4Mbit x 8, or 4 banks x 8Mbit x 4. The V54C3128(16/80/40)4V(BGA) achieves high-speed data transfer rates of up to 166 MHz by using a chip architecture that prefetches multiple bits and synchronizes the output data to a system clock. All control, address, data input, and output circuits are synchronized with the positive edge of an externally supplied clock.
