Features
1. Description
The AT29C512 is a 5-volt only in-system Flash programmable and erasable read only
memory (PEROM). Its 512K of memory is organized as 65,536 words by 8 bits. Man-
ufactured with Atmel’s advanced nonvolatile CMOS technology, the device offers
access times to 70 ns with power dissipation of just 275 mW over the industrial tem-
perature range. When the device is deselected, the CMOS standby current is less
than 300µA. The device endurance is such that any sector can typically be written to
in excess of 10,000 times.
To allow for simple in-system reprogrammability, the AT29C512 does not require high
input voltages for programming. Five-volt-only commands determine the operation of
the device. Reading data out of the device is similar to reading from an EPROM.
Reprogramming the AT29C512 is performed on a sector basis; 128 bytes of data are
loaded into the device and then simultaneously programmed.
During a reprogram cycle, the address locations and 128 bytes of data are internally
latched, freeing the address and data bus for other operations. Following the initiation
of a program cycle, the device will automatically erase the sector and then program
the latched data using an internal control timer. The end of a program cycle can be
detected by DATA polling of I/O7. Once the end of a program cycle has been
detected, a new access for a read or program can begin.

... Device Operation 4.1 Read The AT29C512 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 high. This dual-line control gives designers flexibility in preventing bus contention ...

... Software Data Protection A software controlled data protection feature is available on the AT29C512. Once the software protection is enabled a software algorithm must be issued to the device before a program may be performed. The software protection feature may be enabled or disabled by the user; when shipped from Atmel, the software data protection feature is disabled. To enable the software data protection, a series of three program commands to specific addresses with specific data must be performed ...

... DATA Polling The AT29C512 features DATA polling to indicate the end of a program cycle. During a program cycle an attempted read of the last byte loaded will result in the complement of the loaded data on I/O7. Once the program cycle has been completed, true data is valid on all outputs and the next cycle may begin ...
