Type 1
The device is erased by executing the Erase command sequence; the device internally con-
trols the erase operation. The memory is divided into four blocks for erase operations. There
are two 4K word parameter block sections: the boot block, and the main memory array block.
The typical number of program and erase cycles is in excess of 10,000 cycles.
The optional 8K word boot block section includes a reprogramming lockout feature to provide
data integrity. This feature is enabled by a command sequence. Once the boot block program-
ming lockout feature is enabled, the data in the boot block cannot be changed when input
levels of 5.5 volts or less are used. The boot sector is designed to contain user secure code.
For the AT49F8192A(T), the BYTE pin controls whether the device data I/O pins operate in
the byte or word configuration. If the BYTE pin is set at a logic “1” or left open, the device is in
word configuration, I/O0 - I/O15 are active and controlled by CE and OE.
If the BYTE pin is set at logic “0”, the device is in byte configuration, and only data I/O pins
I/O0 - I/O7 are active and controlled by CE and OE. The data I/O pins I/O8 - I/O14 are tri-
stated and the I/O15 pin is used as an input for the LSB (A-1) address function.
