HCS515 DECODER
The HCS515 can be used in “ stand-alone mode ” , con-
The HCS515 is a low cost integrated K EE L OQ decoder
in a convenient 14-pin package.
The decoder contains non-volatile memory (EEPROM)
to store the Serial Number and Synchronization Infor-
mation of up to seven transmitters. There is also an
additional 1 Kbit of User storage space.
necting the S0:S1 outputs directly to system outputs, or
used in “ co-processor mode ” in conjunction with a
microcontroller when the CLOCK and DATA synchro-
nous communication lines are used.
The HCS515 decoder can be configured by the Evalu-
ation Kit software to perform Normal Learn or Secure
Learn operation using the Decrypt Algorithm as the Key
Generation algorithm.
FIGURE 7-6:
THE HCS515 CONFIGURATION DIALOG BOX.
In this dialog box the user can:
7.3
Demo Decoders Outputs
? assign text as a title or description of the decoder.
The entry will be recorded in the project configura-
tion file for documentation purposes.
? change the Manufacturer Code used for the Key
Generation process during Learning
? select the desired learning scheme among:
- Normal Learn
- Secure Learn - Decrypt
? enable the Repeat feature. Repeat instructs the
decoder to maintain the outputs active as long as
the user presses an encoder button.
S0:S3 – The outputs mirror the buttons pressed on a
learned transmitter.
LEARN OUT – The learn output gives the user feed-
back during a learn sequence. During normal operation
the LEARN LED flashes briefly whenever a K EE L OQ
transmission is received.
FUNC OK – The FUNC OK output is activated when
the received function code matches the function code
received when the decoder was learned
VLOW – The output is activated when the V LOW bit is
set in a transmission. A K EE L OQ encoder sets this bit
when the battery supply voltage drops below the prede-
termined threshold.
