Rev. 1089B–10/98  
To allow for simple in-system reprogrammability, the  
AT49F516 does not require high input voltages for pro-  
gramming. 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 repro-  
gramming 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 perma-  
nently protected from being erased or reprogrammed.

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 conten-  
tion.  
cycle waveforms. The Main Memory Erase operation is  
internally controlled; it will automatically time to completion.  
WORD PROGRAMMING: Once the memory array is  
erased, the device is programmed (to a logical “0”) on a  
word-by-word basis. Please note that a data “0” cannot be  
programmed back to a “1”; only erase operations can con-  
vert “0”s to “1”s. Programming is accomplished via the  
internal device command register and is a 4 bus cycle  
operation (please refer to the Command Definitions table).  
The device will automatically generate the required internal  
program pulses.  
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 com-  
mand (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 sec-  
tion will be erased. After a chip erase, the device will return  
to the read mode.  
The program cycle has addresses latched on the falling  
edge of WE or CE, whichever occurs last, and the data  
latched on the rising edge of WE or CE, whichever occurs  
first. Programming is completed after the specified tBP cycle  
time. The DATA polling feature may also be used to indicate  
the end of a program cycle.  
MAIN MEMORY ERASE: As an alternative to the chip  
erase, a main memory block erase can be performed which  
will erase all bytes not located in the boot block region to an  
FFH. Data located in the boot region will not be changed  
during a main memory block erase. The Main Memory  
Erase command is a six bus cycle operation. The address  
(5555H) is latched on the falling edge of the sixth cycle  
while the 30H data input is latched on the rising edge of  
WE. The main memory erase starts after the rising edge of  
WE of the sixth cycle. Please see Main Memory Erase  
BOOT BLOCK PROGRAMMING LOCKOUT: The device  
has one designated block that has a programming lockout  
feature. This feature prevents programming of data in the  
designated block once the feature has been enabled. The  
size of the block is 8K words. This block, referred to as the  
boot block, can contain secure code that is used to bring up  
the system. Enabling the lockout feature will allow the boot  
code to stay in the device while data in the rest of the  
AT49F516

AT49F516  
device is updated. This feature does not have to be acti-  
vated; the boot block’s usage as a write protected region is  
optional to the user. The address range of the boot block is  
0000H to 1FFFH.  
grammer to identify the correct programming algorithm for  
the Atmel product.  
For details, see Operating Modes (for hardware operation)  
or Software Product Identification. The manufacturer and  
device code is the same for both modes.  
Once the feature is enabled, the data in the boot block can  
no longer be erased or programmed. Data in the main  
memory block can still be changed through the regular pro-  
gramming method and can be erased using either the chip  
erase or the main memory block erase command. To acti-  
vate the lockout feature, a series of six program commands  
to specific addresses with specific data must be performed.  
Please refer to the Command Definitions table.  
DATA POLLING: The AT49F516 features DATA polling to  
indicate the end of a program or erase cycle. During a pro-  
gram 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 polling  
may begin at any time during the program cycle.  
BOOT BLOCK LOCKOUT DETECTION: A software  
method is available to determine if programming of the boot  
block section is locked out. When the device is in the soft-  
ware product identification mode (see Software Product  
Identification Entry and Exit sections) a read from address  
location 0002H will show if programming the boot block is  
locked out. If the data on I/O0 is low, the boot block can be  
programmed; if the data on I/O0 is high, the program lock-  
out feature has been activated and the block cannot be  
programmed. The software product identification exit code  
should be used to return to standard operation.  
TOGGLE BIT: In addition to DATA polling the AT49F516  
provides another method for determining the end of a pro-  
gram 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.  
HARDWARE DATA PROTECTION: Hardware features  
protect against inadvertent programs to the AT49F516 in  
the following ways: (a) VCC sense: if VCC is below 3.8V (typ-  
ical), the program function is inhibited. (b) Program inhibit:  
holding any one of OE low, CE high or WE high inhibits  
program cycles. (c) Noise filter: Pulses of less than 15 ns  
(typical) on the WE or CE inputs will not initiate a program  
cycle.  
PRODUCT IDENTIFICATION: The product identification  
mode identifies the device and manufacturer as Atmel. It  
may be accessed by hardware or software operation. The  
hardware operation mode can be used by an external pro-
