Product Details
HCS200/SN - KEELOQ Code-Hopping Encoder
HCS200/SN from Microchip Technology is a programmable code-hopping transmitter encoder for remote secure access and keyless-entry systems.
Specifications were checked against the manufacturer data sheet and current distributor listing.
Overview
HCS200 combines a programmable 64-bit encryption key, 28-bit serial number, synchronization counter and button inputs to produce a 66-bit hopping-code transmission.
Key Advantages
Changes the transmitted code after each activation to resist simple replay attacks.
Integrates button encoding, battery-low indication and nonvolatile synchronization data for compact transmitters.
Available in an established surface-mount or through-hole ordering format.
Electrical and environmental limits are defined by the official data sheet.
Feature Summary
Generation of KEELOQ rolling-code RF transmitter messages
Button inputs and a serial encoded-data output for an RF transmitter
3.5 V to 13.0 V operation; industrial remote-control applications
8-SOIC (0.154", 3.90mm Width)
Package & Footprint
This ordering code uses the 8-SOIC (0.154", 3.90mm Width) package.
Pin Functions
Confirm exact numbering and the latest land pattern before PCB release.
