Description

The AT29C256 is a five-volt-only in-system Flash programmable and erasable read only memory (PEROM). Its 256K of memory is organized as 32,768 words by 8 bits. Manufactured with Atmel’s advanced nonvolatile CMOS technology, the device offers access times to 70 ns with power dissipation of just 275 mW. 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.

Block Diagram

To allow for simple in-system reprogrammability, the AT29C256 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 a static RAM. Reprogramming the AT29C256 is performed on a page basis; 64 bytes of data are loaded into the device and then simultaneously programmed. The contents of the entire device may be erased by using a six-byte software code (although erasure before pro­gramming is not needed).
During a reprogram cycle, the address locations and 64 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 page and then program the latched data using an internal control timer. The end of a program cycle can be detected by DATA access for a read, program or chip erase can begin.

Device Operation

READ: The AT29C256 is accessed like a static RAM. 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.
BYTE LOAD: A byte load is performed by applying a low pulse on the WE with CE edge of CE CE software codes for data protection and chip erasure.
or WE low (respectively) and OE high. The address is latched on the falling
or WE, whichever occurs last. The data is latched by the first rising edge of
or WE. Byte loads are used to enter the 64 bytes of a page to be programmed or the

page is to be changed, data for the entire page must be loaded into the device. Any byte that is not loaded during the programming of its page will be indeterminate. Once the bytes of a page are loaded into the device, they are simultaneously programmed during the internal programming period. After the first data byte has been loaded into the device, successive bytes are entered in the same manner. Each new byte to be pro­grammed must have its high-to-low transition on WE high transition of WE
(or CE) of the preceding byte. If a high-to-low transition is not detected within 150 µs of the last low-to-high transition, the load period will end and the internal programming period will start. A6 to A14 specify the page address. The page address must be valid during each high-to-low transition of WE the byte address within the page. The bytes may be loaded in any order; sequential loading is not required. Once a programming operation has been initiated, and for the duration of t
, a read operation will effectively be a polling operation.
WC
SOFTWARE DATA PROTECTION: A software controlled data protection feature is available on the AT29C256. 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. After the software data protection is enabled the same three program com­mands must begin each program cycle in order for the programs to occur. All software program commands must obey the page program timing specifications. Once set, the software data protection feature remains active unless its disable command is issued. Power transitions will not reset the software data protection feature, however the soft­ware feature will guard against inadvertent program cycles during power transitions.

Once set, software data protection will remain active unless the disable command sequence is issued.
After setting SDP, any attempt to write to the device without the three-byte command sequence will start the internal write timers. No data will be written to the device; how­ever, for the duration of t

PRODUCT IDENTIFICATION: The product identification mode identifies the device
and manufacturer and may be accessed by a hardware operation. For details, see Operating Modes or Product Identification.
DATA POLLING: The AT29C256 features DATA gram 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. DATA begin at any time during the program cycle.
TOGGLE BIT: In addition to DATA determining the end of a program or erase cycle. During a program or erase operation, successive attempts to read data from the device will result in I/O6 toggling between one and zero. Once the program cycle has completed, I/O6 will stop toggling and valid data will be read. Examining the toggle bit may begin at any time during a program cycle.
OPTIONAL CHIP ERASE MODE: The entire device can be erased by using a six-byte software code. Please see Software Chip Erase application note for details.
