IS61C5128AL/AS IS64C5128AL/AS
Datasheet is here: http://www.issi.com/WW/pdf/61-64C5128AL.pdf
There are 7 versions of the chip, as described in the datasheet. 4 of them are actually different symbols (due to different pinout), 3 of them are aliases. Unfortunately, I haven't set the footprint and footprint filters, because I couldn't find the appropriate footprints in the KiCad library :( Maybe they are compatible with existing footprints with an existing name, but I don't have a lot of experience with these kind of SMD packages. I have added the names of the packages (as described in the datasheet) to the descriptions. These are: SOJ-36 TSOP II-44 TSOP II-32 SOP-32 STSOP I-32
