DESCRIPTION
The TC5164(5)405BJ/BFT/BJS/BFTS is an EDO (hyper page) dynamic RAM organized as 16,777,216
words by 4 bits. TC5164(5)405BJ/BFT/BJS/BFTS utilizes TOSHIBA's CMOS silicon gate process
technology as well as advanced circuit techniques to provide wide operating margins, both internally
and to the system user. Multiplexed address inputs permit the TC5164(5)405BJ/BFT/BJS/BFTS to be
packaged in either a 32-pin plastic SOJ or a 32-pin plastic TSOP. The package size provides high
system bit densities and is compatible with widely available automated testing and insertion
equipment. Other features include a single power supply of 3.3V±0.3V tolerance and direct interfacing
with high performance logic families such as LVTTL.
