16–Bit Flow–Through EDAC  
Error Detection And Correction unit  
1. Introduction  
The 29C516E Atmel EDAC is a very low power  
the corrupted data is placed on the output port and the

(EDAC) with two user data buses. The EDAC is used in more than two errors, then some bit patterns may appear

the 29C516E verifies the entire checkword and data  
The 29C516E acts as a data buffer for µP–memory  
interfacing. A flow–through EDAC is placed in the data

When the 29C516E uses 6–checkbit, it can detect any  
users of one memory space. So, it forms the interface

signaled to the master system (via 2 error Flags) in order  
create a dual port bus in front of memory space. The  
User–1(2) can transfer data from/to the memory or  
to allow the processor to make the required action.  
The 29C516E operates in two possible modes: corrected  
or detected mode. In the corrected mode, the single–bit in  
error is complemented (corrected). Then, the available  
entire data is placed on the output port and the Correctable  
Error Flag is set. In case of double–bit errors (or more),

read or write memory cycles processed by the User–1(2),  
the User–2(1) have the possibility to listen the  
transferred data.
