EM63A165TS-7G

The Etron Technology, Inc. EM63A165TS-7G is a high-speed CMOS synchronous DRAM with a density of 256 Mbits. It is internally configured as 4 banks of 4M word x 16-bit DRAM, featuring a synchronous interface where all signals are registered on the positive edge of the clock signal.

Key electrical specifications include a fast clock cycle time of 5 ns and an access time from clock of 4.5 ns. The device operates from a single +3.3V ±0.3V power supply and supports programmable mode registers for CAS Latency (2 or 3) and Burst Length (1, 2, 4, 8, or full page). It also features Auto Refresh and Self Refresh capabilities, with 8192 refresh cycles required every 64ms.

Available in two package types: a 54-pin 400 mil plastic TSOP II and a 54-ball 8.0 x 8.0 x 1.2mm (max) FBGA. Both package options are Pb-free and Halogen-free. The operating temperature range for this commercial-grade component is 0°C to 70°C.

This SDRAM is well-suited for applications requiring high memory bandwidth, particularly in high-performance PC applications. Its internal pipelined architecture and programmable features allow for optimized performance.
