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.
