Description
The µPD45128163 is high-speed 134,217,728-bit synchronous dynamic random-access memory, organized as 2,097,152 ×16 ×4 (word ×bit ×bank). The synchronous DRAM achieved high-speed data transfer using the pipeline architecture. All inputs and outputs are synchronized with the positive edge of the clock. The synchronous DRAM is compatible with Low Voltage TTL (LVTTL).
This product is packaged in 54-pin TSOP (II).
