1. Description  
AT49BV040A  
Not Recommended  
for New Design  
Contact Atmel to discuss  
the latest design in trends  
and options  
The AT49BV040A is a 2.7-volt-only in-system reprogrammable Flash Memory. Its  
4 megabits of memory is organized as 524,288 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 54 mW over the commercial temperature range.  
When the device is deselected, the CMOS standby current is less than 50 µA. To  
allow for simple in-system reprogrammability, the AT49BV040A does not require high  
input voltages for programming. Three-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; it has standard CE, OE, and WE inputs to avoid bus conten-  
tion. Reprogramming the AT49BV040A is performed by erasing a block of data and  
then programming on a byte by byte basis. The byte programming time is a fast 30 µs.  
The end of a program cycle can be optionally detected by the DATA polling feature.  
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 device is erased by executing the erase command sequence; the device inter-  
nally controls the erase operations. There are two 8K byte parameter block sections,  
eight main memory blocks, and one boot block.  
The device has the capability to protect the data in the boot block; this feature is  
enabled by a command sequence. The 16K-byte boot block section includes a repro-  
gramming 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 perma-  
nently protected from being reprogrammed.
