Publication Release Date: June 1999

Revision A1
Toggle Bit (DQ
6
)- Write Status Detection
In addition to data polling, the W49F201 provides another method for determining the end of a
program cycle. During the internal program or erase cycle, any consecutive attempts to read DQ
6
will
produce alternating 0's and 1's. When the program or erase cycle is completed, this toggling between
0's and 1's will stop. The device is then ready for the next operation.
Product Identification
The product ID operation outputs the manufacturer code and device code. Programming equipment
automatically matches the device with its proper erase and programming algorithms.
The manufacturer and device codes can be accessed by software or hardware operation. In the
software access mode, a six-word (or JEDEC 3-word) command sequence can be used to access the
product ID. A read from address 0000H outputs the manufacturer code, 00DA(hex). A read from
address 0001(hex) outputs the device code, 00AE(hex). The product ID operation can be terminated
by a three-word command sequence or an alternative one-word command sequence (see Command
Definition table).
In the hardware access mode, access to the product ID is activated by forcing CE and OE low, WE
high, and raising A9 to 12 volts.
