HCS300T-I/SN

HCS300T-I/SN is a microcontroller device in the HCS300 family, designed for embedded real‑time control. It combines a CPU core with on‑chip memory and a range of peripherals to handle sensing, actuation, and communication tasks in a compact package. Typical features include on‑chip flash and RAM, timers/counters, ADC (and PWM), and serial interfaces (UART/SPI/I2C), plus low‑power sleep modes and flexible clock options. The I/SN suffix usually denotes industrial temperature rating and RoHS‑compliant, lead‑free packaging. It’s suitable for applications such as motor control, power management, sensor interfaces, and general embedded control in appliances and automotive equipment. For exact specifications (CPU speed, memory size, pin count, peripherals), consult the manufacturer’s datasheet for the specific variant, as features vary by package and revision. If you can share the manufacturer, I can provide a more precise summary.

Direct equivalents for HCS300T-I/SN do not exist; it’s a legacy Microchip HCS remote-entry transponder/encoder IC. The closest substitutes are other HCS family parts if electrical/functional specs match. For an official cross-reference, contact Microchip or check distributor cross-reference tools.

Pin count: 28 pins (28-pin package).
Function: An 8‑bit high‑security microcontroller with on‑chip ROM/RAM and cryptographic/secure features, designed for automotive immobilizer and remote keyless entry applications.

Application areas of HCS300T-I/SN (high‑speed CAN controller):
