The HCS101 from Microchip Technology Inc. is a fixed code encoder designed for remote control systems. It offers a small package size and low cost, making it an ideal solution for one-way remote control systems. The device is pin-compatible with Microchip's HCS201 hopping code encoder, facilitating upgrades to more secure RKE systems. The 8-pin HCS101 operates over a wide voltage range of 3.5V to 13.3V and features three button inputs, allowing system designers to utilize up to 7 functions. The only components required for device operation are buttons and an RF circuit, enabling very low system cost.
