The HCS370T-I/ST from Microchip Technology is a secure code hopping encoder utilizing KEELOQ® technology. It is designed for unidirectional authentication and access control systems, offering high security with a small package outline and low cost.
This encoder operates within a voltage range of 2.05V to 5.5V and features six button inputs that provide 15 functions. It supports various modulation types including PWM, VPWM, PPM, and Manchester. The device includes on-chip EEPROM for storing programmable serial numbers, encoder keys, and seed values, with crypt keys being read-protected.
The HCS370T-I/ST is ideal for Remote Keyless Entry (RKE) applications such as automotive RKE systems, alarm systems, immobilizers, and gate or garage door openers. It is housed in a compact 14-TSSOP surface mount package, minimizing board space.
Key security features include unique transmissions for each code, a 67/69-bit transmission code length, and a 32-bit hopping code to prevent code scanning and grabbing. The device also transmits a battery low signal to the receiver and supports dual encoder functionality.
