Autoselect Mode

The autoselect mode provides manufacturer and device identification, and sector protection verification,

through identifier codes output on DQ7–DQ0. This mode is primarily intended for programming equipment to

automatically match a device to be programmed with its corresponding programming algorithm. However, the

autoselect codes can also be accessed in-system through the command register.

When using programming equipment, the autoselect mode requires VID on address pin A9. Address pins

must be as shown in Table 10.10 on page 40 and Table 10.11 on page 40. In addition, when verifying sector

protection, the sector address must appear on the appropriate highest order address bits (see Table 10.4

on page 21). Table 10.10 and Table 10.11 show the remaining address bits that are don’t care. When all

necessary bits have been set as required, the programming equipment may then read the corresponding

identifier code on DQ7–DQ0. However, the autoselect codes can also be accessed in-system through the

command register, for instances when the device is erased or programmed in a system without access to

high voltage on the A9 pin. The command sequence is illustrated in Table 15.1 on page 62. Note that if a

Bank Address (BA) (on address bits PL127J: A22–A20, PL129J and PL064J: A21–A19, PL032J: A20–A18) is

asserted during the third write cycle of the autoselect command, the host system can read autoselect data

that bank and then immediately read array data from the other bank, without exiting the autoselect mode.
