Product Details
HCS300/SN - KEELOQ Code-Hopping Encoder
HCS300/SN from Microchip Technology is a programmable code-hopping encoder for unidirectional remote keyless-entry transmitters.
Specifications were checked against the manufacturer data sheet and current distributor listing.
Overview
HCS300 combines a nonlinear KEELOQ hopping-code generator, EEPROM, oscillator, four button inputs and PWM output in an 8-pin device.
Key Advantages
Makes each 66-bit transmission unique to resist code capture and replay.
Integrates timing, EEPROM, LED drive and button pull-downs.
Available in an established surface-mount or through-hole ordering format.
Electrical and environmental limits are defined by the official data sheet.
Feature Summary
