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.

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.
