DESCRIPTION
The HCS101 from Microchip Technology Inc. is a fixed
code encoder designed for remote control systems. It
provides a small package outline and low cost to make
this device a perfect solution for unidirectional remote
control systems.
It is also pin compatible with Microchip’s HCS201 Code
Hopping Encoder allowing easy upgrading to a more
secure remote keyless entry (RKE) system.

Preliminary
The 8-pin HCS101 operates over a wide voltage range
of 3.5V to 13.3V and has three button inputs allowing
the system designer the freedom to utilize up to 7 func-
tions. The only components required for device opera-
tion are the buttons and RF circuitry, allowing a very low
system cost.
