HCS200

KEELOQ Code Hopping Encoder

FEATURES

Security

DESCRIPTION

The HCS200 from Microchip Technology Inc. is a code

hopping encoder designed primarily for Remote Key-

less Entry (RKE) systems. The device utilizes the

KEELOQ^®code hopping technology, incorporating high

security, a small package outline and low cost. The

HCS200 is a perfect replacement of fixed code devices

in unidirectional remote keyless entry systems and

access control systems.

• Programmable 28-bit serial number

• Programmable 64-bit crypt key

• Each transmission is unique

• 66-bit transmission code length

• 32-bit hopping code

• 28-bit serial number, 4-bit button status,

low battery indicator transmitted

Typical Applications

The HCS200 is ideal for Remote Keyless Entry (RKE)

applications. These applications include:

PWM

32-bit shift register

• Fixed code replacement

• Automotive RKE systems

• Automotive alarm systems

• Automotive immobilizers

• Gate and garage door openers

• Identity tokens

The HCS200 operates over a wide voltage range of

3.5 volts to 13.0 volts and has three button inputs in an

8-pin configuration. This allows the system designer

the freedom to implement up to seven functions. The

only components required for device operation are the

buttons and RF circuitry, allowing

system cost.
