AC Measurements assume tT = 5ns. 2. Assumes that tRCD<=tRCD(max) and tRAD<=tRAD(max). If tRCD or tRAD is greater than the maximum recommended value shown in this table, tRAC exceeds the value shown. 3. Measured with a load circuit equivalent to 2TTL loads and 100U. 4. Assumes that tRCD>=tRCD(max) and tRAD<=tRAD(max). 5. Assumes that tRCD<=tRCD(max) and tRAD>=tRAD(max). 6. tOFF(max) defines the time at which the output achieves the open circuit condition and is not referenced to output voltage levels. 7. VIH(min) and VIL(max) are reference levels for measuring timing of input signals. Also, transition times are measured between VIH and VIL. 8. Operation with the tRCD(max) limit insures that tRAC(max) can be met, tRCD(max) is specified as a reference point only; if tRCD is greater than the specified tRCD(max) limit, then access time is controlled exclusively by tCAC. 9. Operation with the tRAD(max) limit insures that tRAC(max) can be met, tRAD(max) is specified as a reference point only; if tRAD is greater than the specified tRAD(max) limit, then access time is controlled exclusively by tAA. 7 LG Semicon GM71C(S)4400C/CL 10. tWCS, tRWD, tCWD tCPW and tAWD are not restrictive operating parameters. They are included in the data sheet as electrical characteristics only; if tWCS >=tWCS(min), the cycle is an early write cycle and the data out pin will remain open circuit (high impedance) throughout the entire cycle; if tRWD>=tRWD(min), tCWD>=tCWD(min), tAWD>=tAWD(min) and tCPW>=tCPW(min), the cycle is a readmodify-write and the data output will contain data read from the selected cell; if neither of the above sets of conditions is satisfied, the condition of the data out (at access time) is indeterminate. 11. These parameters are referenced to CAS leading edge in early write cycles and to WE leading edge in delayed write or a read modify write cycle. 12. tRASP defines RAS pulse width in fast page mode cycles. 13. Access time is determined by the longer of tAA or tCAC or tACP. 14. An initial pause of 100us is required after power up followed by a minimum of eight initialization cycles (RAS only refresh cycle or CAS before RAS refresh cycle). If the internal refresh counter is used, a minimum of eight CAS before RAS refresh cycles is required. 15. In delayed write or read-modify-write cycles, OE must disable output buffer prior to applying data to the device. 16. Test mode operation specified in this data sheet is 2-bit test function controlled by control address bits - - - CA0. This test mode operation can be performed by WE-and-CAS-before-RAS (WCBR) refresh cycle. Refresh during test mode operation will be performed by normal read cycles or by WCBR refresh cycles. When the state of two test bits accord each other, the condition of the output data is low level. In order to end this test mode operation, perform a RAS only refresh cycle or a CAS-before-RAS refresh cycle. 17. In a test mode read cycle, the value of tRAC, tAA, tCAC, tOAC and tACP is delayed for 2ns to 5ns for the specified value. These parameters should be specified in test mode cycles by adding the above value to the specified value in this data sheet. 8 LG Semicon GM71C(S)4400C/CL Unit: Inches (mm) Package Dimension 20 (26) SOJ 0.025(0.63) MIN 0.039(1.00) MAX 0.305(7.75) MAX 0.340(8.64) MAX 0.260(6.60) MIN 0.275(6.99) MAX 0.008(0.20) 0.295(7.49) MIN 0.330(8.38) MIN 0.661(16.80) MIN 0.669(17.00) MAX 0.085(2.16) MIN 0.103(2.61) MAX 0.128(3.25) MIN 0.148(3.76) MAX 0.050(1.27) TYP 0.015(0.38) MIN 0.021(0. 53) MAX 0.026(0.66) MIN 0.036(0.91) MAX 20 (26) TSOP II 0~8 0.308(7.82) MAX 0.292(7.42) MIN o 0.012(0.30) MIN 0.028(0.70) MAX 0.009(0.22) MAX 0.667(16.94) MIN 0.690(17.54) MAX 0.041(1.03) MIN 0.048(1.23) MAX 0.012(0.30) MIN 0.020(0.50) MAX 0.050(1.27) TYP 0.001(0.03) MIN 0.009(0.23) MAX 0.371(9.42) MAX 0.355(9.02) MIN 23 |
