NOTES:
1. In the write operation mode, BYTE/VPP should be set to 10V±0.5V.
2. 5555H and 2AAAH address command codes stand for Hex number starting from A0 to A14.
3. RA=Address of the memory location to be read.
RD=Data read from location RA during read operation.
PA=Address of the memory location to be programmed.
PO=Data to be programmed at location PA.

SILICON ID READ
The Silicon ID Read mode allows the reading out of a
binary code from the device and will identify its manu-
facturer and type. This mode is intended for use by
programming equipment for the purpose of automati-
cally matching the device to be programmed with its
corresponding programming algorithm. This mode is
functional over the entire temperature range of the de-
vice.
MX27C1610 Silion ID Codes
To activate this mode, the programming equipment must
force VID (10V±o.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
MX27C1610 is programmed in a system without access
to high voltage on the A9 pin.
