HY29F040A

protect and sector unprotect features can be en-

abled in a PROM programmer.

The HY29F040A needs a single 5.0 volt power-

supply for read, program and erase operation. In-

ternally generated and well regulated voltages are

provided for program and erase operation. A low

Vcc detector inhibits write operations on loss of

power. End of program or erase is detected by /Data

Polling of DQ7 or by the Toggle Bit feature on DQ6.

Once program or erase cycle is successfully com-

pleted, the device internally resets to the Read

mode.
