signature mode
The signature mode provides access to a binary code identifying the manufacturer and type. This mode is
activated when A9 ( pin 31 for the J package) is forced to 12 V. Two identifier bytes are accessed by toggling
A0. DQ0−DQ7 contain the valid codes. All other addresses must be held low. The signature code for these
devices is 9730. A0 low selects the manufacturer’s code 97 ( Hex), and A0 high selects the device code 30
( Hex), as shown in Table 3.
