EDS6432AFBH Datasheet | Elpida Memory

Description The EDS6432AFBH, EDS6432CFBH are 64M bits SDRAMs organized as 524,288 words × 32 bits × 4 banks. All inputs and outputs are synchronized with .. the positive edge of the clock. Supply voltages are 3.3V (EDS6432AFBH) and 2.5V (EDS6432CFBH). They are packaged in 90-ball FBGA. Pin Configurations /xxx indicate active low signal. 90-ball FBGA 1 2 3 4 5 6 7 8 9 DQ26 DQ24 VSS VDD DQ23 DQ21 VDDQ VSSQ DQ19 DQ22 DQ20 VDDQ DQ17 DQ18 VDDQ NC A2 A10 NC BA0 /CAS DQ6 DQ1 DQ28 VDDQ VSSQ Features - - - - - 3.3V and 2.5V power supply Clock frequency: 166MHz/133MHz (max.)
