Autoselect Mode

The autoselect mode provides manufacturer and de-

vice identification, and sector protection verification,

through identifier codes output on DQ7–DQ0. This

mode is primarily intended for programming equip-

ment to automatically match a device to be pro-

grammed 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 (8.5 V to 12.5 V) on address A9.

Addresses A6, A1, and A0 must be as shown in

Table 4, on page 19. In addition, when verifying sector

protection, the sector address must appear on the ap-

propriate highest order address bits (see Table 2, on

page 11 and Table 3, on page 15). Table 4 shows the

remaining address bits that are don’t care. When all

necessary bits have been set as required, the pro-

gramming equipment may then read the correspond-

ing identifier code on DQ7–DQ0.

To access the autoselect codes in-system, the host

system can issue the autoselect command via the

command register, as shown in Table 10, on page 30.

This method does not require VID. Refer to the “Au-

toselect Command Sequence” on page 26 section for

more information.

Table 4. Am29LV652D Autoselect Codes, (High Voltage Method)

Legend: L = Logic Low = VIL, H = Logic High = VIH, SA = Sector Address, X = Don’t care.

Notes:

1. CE# can be replaced with CE2# when referring to the second die in the package.

2. The device ID’s used for the Am29LV652 are the same as the Am29LV065, because the Am29LV652 uses two Am29LV065

dice and appears to the system as two Am29LV065 devices.
