Product Details
HCS362T-I/SN - Tape-and-Reel Industrial KEELOQ Encoder
Microchip Technology HCS362T-I/SN is an industrial-temperature, four-button code-hopping encoder in an 8-lead plastic SOIC, supplied on tape and reel.
Device, pinout, and ordering characteristics follow Microchip HCS362 datasheet DS40189E.
Overview
The HCS362 produces a 69-bit transmission with a 32-bit encrypted hopping portion and a 37-bit fixed portion. Four switch inputs support up to 15 functions for remote-control systems. The HCS362T device designation specifies tape-and-reel ordering; I identifies −40 to +85 °C, and SN specifies the 8-lead plastic SOIC. A compatible receiver must learn the encoder key and maintain synchronization.
Key Advantages
The encrypted hopping field changes across transmissions to resist simple captured-code replay.
Four inputs allow up to 15 encoded functions.
Programmable keys and configuration are stored in on-chip EEPROM with read protection.
Tape-and-reel presentation accompanies the industrial −40 to +85 °C order grade.
Feature Summary
69 bits comprise 32 encrypted hopping bits and 37 fixed bits.
Two programmable 64-bit encryption keys and a 60-bit seed support the specified learning modes.
PWM or Manchester encoding and selectable timing support compatible RF circuitry.
Queue counter, timer bits, programmable timeout, and tunable oscillator are documented by Microchip.
Package & Footprint
SN denotes an 8-lead plastic SOIC with a nominal 150 mil body. The site's catalog specifies 8-SOIC, 0.154-inch width, matching its existing normalized package entry. The T in HCS362T specifies tape-and-reel ordering, not a different pinout. Confirm mechanical dimensions and pin-1 orientation against DS40189E.
- Use the manufacturer SOIC land pattern and top-view orientation.
- Connect DATA and RFEN according to the chosen transmitter interface.
- Provide local supply decoupling and correct switch-input wiring.
The registered package and local JPG were checked. This illustration is not a dimensional drawing.

Replacement Considerations
HCS362-I/SN is the separate non-T order form in the product database. Confirm packaging and assembly needs before selecting between order forms. Other HCS encoders are not automatically interchangeable; compare transmission format, pin functions, provisioning, synchronization, package, and temperature grade. No unverified internal alternative link is provided.
Manufacturer Information
Microchip Technology publishes HCS362 datasheet DS40189E with the encoder architecture, electrical characteristics, pinout, package, and product identification system. Its ordering table defines HCS362T as tape and reel, I as −40 to +85 °C, and SN as the 8-lead plastic SOIC.
Applications
Encode button commands for a matching receiver.
Support multiple enrolled remote functions.
Transmit configured actions for a security receiver.
Use a programmed encoder identity in a unidirectional link.
Quality & Authenticity
Verify the complete HCS362T-I/SN order code, SOIC marking, reel labeling, and lot traceability. Confirm secure key, serial-number, seed, and configuration programming through an authorized process and test against the intended receiver.
FAQ
What does HCS362T indicate?
It is the tape-and-reel ordering form of the HCS362 encoder.
What does I/SN identify?
I is the industrial −40 to +85 °C grade; SN is the 8-lead plastic SOIC.
Is a receiver integrated?
No. A compatible receiver and external RF transmitter circuitry are needed.
Engineering Notice
Code hopping requires protected key provisioning and correct receiver synchronization. Verify the multiplexed RFEN and LED pins, modulation, oscillator calibration, timing, supply conditions, and complete RF link against DS40189E before release.
