AS29F200 - Alliance Semiconductor

AS29F200 5V 256K x 8/128K x 8 CMOS FLASH EEPROM

Selected by A9 = VID(11.5–12.5V), CE = OE = A1 = A6 = L, enabling outputs. 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 AS29F200. Selected with CE = OE = L, WE = H. Data is valid in tACC time after addresses are stable, tCE after CE is .

Features

single 5.0V power supply operation for both read and write functions. Internally generated and regulated voltages are provided for the program and erase operations. A low VCC detector automatically inhibits write operations during power transtitions. The RY/BY pin, DATA polling of DQ7, or toggle bit (DQ6) may be used to detect end of program or erase operations. The device automatically resets to the read mode after program/erase operations are completed. The AS29F200 resists accidental erasure or spurious programming signals resulting from power transitions. Control register archi tecture per.
