Microchip Technology HCS362T-I/ST

The HCS362 generates a 69-bit transmission containing a 32-bit encrypted hopping field and a 37-bit fixed field. Four button inputs permit up to 15 functions. The T-I/ST order code combines tape-and-reel supply, the industrial −40 to +85 °C grade, and an eight-lead plastic TSSOP. The TSSOP has its own pin assignment, which should be followed in schematic work.

Microchip's ST suffix specifies an eight-lead plastic TSSOP with a 4.4 mm body. The catalog's normalized package is 8-TSSOP. The T prefix identifies the tape-and-reel ordering form, not a change in the device pinout. Confirm the TSSOP mechanical drawing and pin-1 orientation before selecting a land pattern.

Layout checks

• Use the manufacturer TSSOP top-view pin diagram.
• Check DATA and RFEN connections to the transmitter stage.
• Place supply decoupling close to VDD and VSS.

The package image is pending; use the datasheet drawing for exact dimensions.

Confirm multiplexed functions and orientation against the TSSOP package diagram.

Receiver key learning and synchronization are system requirements.

HCS362-I/ST denotes the same device family and ST package without the T tape-and-reel ordering prefix, but assembly supply form differs. The SN SOIC variant is not footprint- or pin-map-equivalent to the ST TSSOP. Compare pinout, programming, modulation, receiver learning, and environmental grade before substitution. No unverified internal link is provided.

Microchip HCS362 datasheet DS40189E documents the transmission format, package-specific pin diagrams, electrical conditions, and product identification system. It defines HCS362T as tape and reel, I as −40 to +85 °C, and ST as the eight-lead, 4.4 mm plastic TSSOP.

Verify the HCS362T-I/ST order code, TSSOP marking, and lot traceability. Program keys, serial identity, seed, and configuration through an authorized process, then test against the intended receiver.

Protect manufacturing keys and verify TSSOP pinout, receiver synchronization, RFEN behavior, timing, oscillator calibration, supply range, and the complete RF link against DS40189E before release.
