Product Details
HCS101-I/SN - Fixed-Code Encoder
HCS101-I/SN from Microchip Technology is a fixed-code encoder for unidirectional remote-control transmitters in an 8-SOIC (0.154", 3.90mm Width) package.
Industrial-temperature, surface-mount ordering option. Check receiver design and code management before using it in a security-sensitive system.
Overview
HCS101 provides a 66-bit fixed-code transmission for remote-control systems. Three switch inputs provide seven button functions. On-chip EEPROM stores programmed serial-number and counter information; a compatible receiver and separate RF transmitter circuitry are still required.
Key Advantages
Operates from 3.5 V to 13.3 V.
S0, S1 and S2 permit seven input combinations.
Includes an oscillator, timing circuitry and code-word completion.
The -I ordering option is specified for -40°C to +85°C ambient operation.
Feature Summary
Two programmable 32-bit serial numbers plus a 10-bit serial-number field are described in the data sheet.
Nonvolatile 16-bit counter is part of the programmed transmitter data.
66-bit code word, selectable baud rate and automatic completion.
Battery-low status can be conveyed to the receiver.
Package & Footprint
The registered package is 8-SOIC (0.154", 3.90mm Width), corresponding to Microchip's 8-lead, 150-mil-body SN outline.
- Observe the top-view pin-1 marker.
- Confirm the current Microchip mechanical drawing and land pattern.
- Check the exact order code and tube handling with the supplier.
The registered local JPG is present; use the manufacturer drawing for dimensions.

Consult the full DC and timing tables for application-specific operating conditions.
Replacement Considerations
Microchip describes HCS101 as pin-compatible with the HCS201 code-hopping encoder, but HCS201 changes the security and receiver protocol. A package match does not make these devices functionally interchangeable. Check the complete ordering code, supply and temperature range, transmitter programming, receiver firmware and regulatory behavior before substitution.
No unverified internal substitute is linked here.
Manufacturer Information
Microchip Technology identifies HCS101 as a fixed-code encoder. The -I option identifies industrial temperature operation and SN identifies the narrow 8-lead SOIC outline. Verify current manufacturer notices and order availability before procurement.
Applications
Button encoding for a compatible unidirectional receiver.
Command data for an external RF stage.
Compact transmitter logic for simple control functions.
Fixed-code signaling where system-level security assessment permits it.
Quality & Authenticity
Verify the full HCS101-I/SN label, lot traceability and package marking. Confirm programmed identity and counter values under a controlled provisioning process, then test the complete transmitter and receiver pair.
FAQ
Is HCS101 a code-hopping encoder?
No. It transmits a fixed-code format; do not infer HCS201 security behavior.
Does the device transmit RF directly?
No. The DATA output feeds external transmitter circuitry.
What does -I mean?
It denotes the industrial ambient option, -40°C to +85°C.
Is a package illustration available?
Yes. The local registered 8-SOIC JPG is present.
Engineering Notice
Use Microchip's HCS101 data sheet for schematic, timing, programming and package design. Fixed-code systems require explicit replay-risk review. Distributor availability and pricing are time-sensitive and are maintained separately from these technical details.
