When A0 is low (VIL) the output data = 52h, a unique Mfr. code for Alliance Semiconductor Flash products. When A0 is high (VIH), DOUT represents the device code for the AS29LV160. Read mode Selected with CE = OE = L, WE = H. Data is valid in tACC time after addresses are stable, tCE after CE is low and tOE after OE is low. Standby Selected with CE = H. Part is powered down, and ICC reduced to <1.0 µA when CE = VCC ± 0.3V = RESET. If activated during an automated on-chip algorithm, the device completes the operation before entering standby. Output disable Part remains powered up; but outputs tri-stated with OE pulled high. Write Selected with CE = WE = L, OE = H. Accomplish all Flash erasure and programming through the command register. Contents of command register serve as inputs to the internal state machine. Address latching occurs on the falling edge of WE or CE, whichever occurs later. Data latching occurs on the rising edge WE or CE, whichever occurs first. Filters on WE prevent spurious noise events from appearing as write commands. Enable sector protect Hardware protection circuitry implemented with external programming equipment causes the device to disable program and erase operations for specified sectors. For in-system sector protection, refer to Sector protect algorithm on page 15. Sector unprotect Disables sector protection for all sectors using external programming equipment. All sectors must be protected prior to sector unprotection. For in-system sector unprotection, refer to Sector unprotect algorithm on page 15. |
