6 / 28 page  6.42 6 IDT71V3557, IDT71V3559, 128K x 36, 256K x 18, 3.3V Synchronous SRAMs with ZBT™ Feature, 3.3V I/O, Burst Counter, and Flow-Through Outputs Commercial and Industrial Temperature Ranges Absolute Maximum Ratings (1) 100 TQFP Capacitance(1) (TA = +25°C, F = 1.0MHZ) Pin Configuration 256K x 18 NOTES: 1. Pins14,64,and66donothavetobeconnecteddirectlytoVSS aslongastheinputvoltage is < VIL. 2. Pin 16 does not have to be connected directly to VDD as long as the input voltage is > VIH. 3. Pins 83 and 84 are reserved for future 8M and 16M respectively. 4. Pin 64 supports ZZ (sleep mode) for the latest die revisions. Top View 100 TQFP NOTE: 1. This parameter is guaranteed by device characterization, but not production tested. NOTES: 1. Stresses greater than those listed under ABSOLUTE MAXIMUM RATINGS may cause permanent damage to the device. This is a stress rating only and functional operation of the device at these or any other conditions above those indicated in the operational sections of this specification is not implied. Exposure to absolute maximum rating conditions for extended periods may affect reliability. 2. VDD terminals only. 3. VDDQ terminals only. 4. Input terminals only. 5. I/O terminals only. 6. This is a steady-state DC parameter that applies after the power supply has reached its nominal operating value. Power sequencing is not necessary; however, the voltage on any input or I/O pin cannot exceed VDDQ during power supply ramp up. 7. TA is the "instant on" case temperature. 100 999897 9695 94939291 90 8786858483 8281 89 88 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 NC NC VDDQ VSS NC I/OP2 I/O15 I/O14 VSS VDDQ I/O13 I/O12 VSS VDD I/O11 I/O10 VDDQ VSS I/O9 I/O8 NC NC VSS VDDQ NC NC 80 79 78 77 76 75 74 73 72 71 70 69 68 67 66 65 64 63 62 61 60 59 58 57 56 55 54 53 52 51 NC VDDQ VSS NC I/OP1 I/O7 I/O6 VSS VDDQ I/O5 I/O4 VSS VDD I/O3 I/O2 VDDQ VSS I/O1 I/O0 NC NC VSS VDDQ NC NC 5282 drw 02a VSS(1) NC NC VDD(2) NC NC VSS(1) A10 VSS/ZZ(1,4) , Symbol Rating Commercial & Industrial Values Unit VTERM (2) Terminal Voltage with Respect to GND -0.5 to +4.6 V VTERM (3,6) Terminal Voltage with Respect to GND -0.5 to VDD V VTERM (4,6) Terminal Voltage with Respect to GND -0.5 to VDD +0.5 V VTERM (5,6) Terminal Voltage with Respect to GND -0.5 to VDDQ +0.5 V TA(7) Commercial Operating Temperature -0 to +70 oC Industrial Operating Temperature -40 to +85 oC TBIAS Temperature Under Bias -55 to +125 oC TSTG Storage Temperature -55 to +125 oC PT Power Dissipation 2.0 W IOUT DC Output Current 50 mA 5282 tbl 06 Symbol Parameter (1) Conditions Max.
