Each TMS41 64FPL is described in the datasheet and is fully electrically tested and processed accordingto Tl's MIL-STD-8838 (as ammended for commercialapplications) flows prior to assembly. Afterassembly onto the SIP, a further set of electrical testsis performed. The TM4164FL8 is rated for operationfrom OOC to 70°C.TM4164FL865,536 BY 8-BIT DYNAMIC RAM MODULEREAD,MODIFY,WRITECYCLE(MIN)260 ns285 ns345 ns3D-PINSINGLE-IN-L1NE PACKAGE(TOP VIEW)VDD (1)CAS (2)DQ1 (3)AO (4)A1 (5)DQ2 (6)A2 (7)A3 (8)Vss (9)DQ3 (10)A4 (11 )A5 (12)DQ4 (13)A6 (14)A7 (15)DQ5 (16)NC (17)NC (18)NC (19)DQ6 (20)W (21)VSS (22)DQ7 (23)NC (24)DQ8 (25)NC (26)RAS (27)NC (28)NC (29)VDD (30)NOVEMBER 19B3DoDoDoDoDoDoDoDoPIN NOMENCLATUREAO-A7 Address InputsCAS Column Address Str?beDQ1-DQ8 Data In/Data OutNC No ConnectionRAS Row Address StrobeVDD +5-V SupplyVSS GroundW Write EnableenQ):;"C0~~-CPRODUCT PREVIEWThis document contains information on a product underdevelopment.
