HCS200/SN Description

Short technical summary and product information.

The HCS200/SN from Microchip Technology is a code hopping encoder utilizing KEELOQ® technology, offering high security for unidirectional remote keyless entry and access control systems. It is designed as a replacement for fixed code devices.

This specialized IC operates over a wide voltage range of 3.5V to 13.0V and features three button inputs, allowing for up to seven functions. The device transmits a 66-bit code word, combining a 32-bit hopping code with a 28-bit serial number and information bits, making each transmission unique and resistant to code scanning or capture.

The HCS200/SN is housed in an 8-SOIC package suitable for surface mounting. It requires minimal external components, primarily buttons and RF circuitry, contributing to a low system cost. The internal EEPROM stores programmable but read-protected crypt keys and synchronization data.

Typical applications include automotive RKE systems, alarm systems, immobilizers, gate and garage door openers, and identity tokens. The device supports selectable baud rates and features internal pull-down resistors on its button inputs.
