HCS300-I/SN (MICROCHIP)
Кодер KEELOQ со скачкообразным изменением кода, последовательный, 2В до 6.3В, SOIC-8
The HCS300-I/SN is a Code Hopping Encoder designed for secure remote keyless entry (RKE) systems. The HCS300 utilizes patented KEELOQ® hopping technology incorporates high security to make this device a perfect solution for unidirectional remote keyless entry systems and access control systems. The HCS300 combines a 32-bit hopping code generated by a non-linear encryption algorithm with a 28-bit serial number and 6 status bits to create a 66-bit transmission stream. The length of the transmission eliminates the threat of code scanning and the code hopping mechanism makes each transmission unique, thus rendering code capture and re-send (code grabbing) schemes useless. The encryption key, serial number and configuration data are stored in EEPROM, which is not accessible via any external connection. This makes the HCS300 a very secure unit.
