8 / 39 page  8 P/N: PM0506 REV.1.7, JUN. 15, 2001 MX29F1610A DEVICE OPERATION SILICON ID READ The Silicon ID Read mode allows the reading out of a binary code from the device and will identify its manufacturer and type. This mode is intended for use by programming equipment for the purpose of automatically matching the device to be programmed with its corresponding programming algorithm. This mode is functional over the entire temperature range of the device. To activate this mode, the programming equipment must force VID (11.5V~12.5V) on address pin A9. Two identifier bytes may then be sequenced from the device outputs by toggling address A0 from VIL to VIH. All addresses are don't cares except A0 and A1. The manufacturer and device codes may also be read via the command register, for instances when the MX29F1610A is erased or programmed in a system without access to high voltage on the A9 pin. The command sequence is illustrated in Table 3. Byte 0 (A0=VIL) represents the manfacturer's code (MXIC=C2H) and byte 1 (A0=VIH) the device identifier code (MX29F1610A=FAH). The Silicon ID Read mode will be terminated after the following write command cycle. Table 4.
