HCS101
1.0
As indicated in the block diagram in Figure 1-1, the
HCS101 has a small EEPROM array, which must be
loaded with several parameters before use. These
parameters include:
• Two 32-bit serial numbers
• 16-bit counter value
• Additional 10-bit serial number
• Configuration data

Transmitted Information
The EEPROM data for each transmitter is programmed
by the manufacturer at the time of production.
Any type of controller may be used as a receiver, but it
is typically a microcontroller with compatible firmware
that allows the receiver to operate in conjunction with a
transmitter, based on the HCS101.
