Five-volt-only commands determine the read and programming operation of the device. Reading data out of the device is similar to reading from an EPROM. Reprogramming the AT49F516 is performed by erasing a block of data entire chip or main memory block and then programming on a word by word basis. The typical word programming time is a fast 10 µs. The end of a program cycle can be optionally detected by the DATA polling fea- ture. Once the end of a byte program cycle has been detected, a new access for a read or program can begin. The typical number of program and erase cycles is in excess of 10,000 cycles. The optional 8K words boot block section includes a reprogramming write lock out feature to provide data integrity. The boot sector is designed to contain user secure code, and when the feature is enabled, the boot sector is permanently protected from being erased or reprogrammed. Block Diagram VCC GND OE WE CE ADDRESS INPUTS OE, CE, AND WE LOGIC Y DECODER X DECODER DATA INPUTS/OUTPUTS I/O15 - I/O0 DATA LATCH INPUT/OUTPUT BUFFERS Y-GATING MAIN MEMORY 24K WORDS OPTIONAL BOOT BLOCK 8K WORDS 7FFFH 2000H 1FFFH 0000H Device Operation READ The AT49F516 is accessed like an EPROM. When CE and OE are low and WE is high, the data stored at the memory location determined by the address pins is asserted on the outputs. The outputs are put in the high impedance state whenever CE or OE is high. This dual-line control gives designers flexibility in preventing bus contention. CHIP ERASE When the boot block programming lockout feature is not enabled, the boot block and the main memory block will erase together from the same chip erase command See command definitions table . If the boot block lockout function has been enabled, data in the boot section will not be erased. However, data in the main memory section will be erased. After a chip erase, the device will return to the read mode.
