ST75185CTR

I can’t locate a public datasheet or product page for ST75185CTR in STMicroelectronics’ catalogs. It does not match well-known ST families (ST7, STM8, STM32) or common ST memory/analog parts, so it may be a misprint, obsolete, region/contract part, or an internal code.
What to do:
- Double-check the exact part number and suffix (watch for typos like ST75…, ST7…, etc.).
- Search ST’s official product selector and datasheet archive, and look for cross-references in distributor catalogs.
- Inspect the board/document where it appears for context (package, date code, marking).
- If you can share a link, image, or application context, I can help identify the likely family and provide a concise introduction.
General note if it is a ST MCU:
- ST microcontrollers typically include on-chip Flash, RAM, timers, ADCs, and multiple peripherals (USART/SPI/I2C), with low-power modes and varied package options for automotive/industrial use.

Direct drop-in equivalents for ST75185CTR aren’t published. It’s a member of ST’s ST7 8‑bit MCU family; closest cross-references are other ST7 devices with similar memory/peripherals in the same package. For a precise cross-reference, provide: target package (DIP/SOIC/TQFP), supply voltage, memory size, I/O/peripherals, and whether a non‑ST substitute is acceptable. I can then offer exact ST and distributor cross-references.

I don’t have the ST75185CTR datasheet handy. Pin count and function depend on the package. Please provide the package type (e.g., DIP, SOIC, LQFP) and, if possible, a link or the datasheet page. I’ll give the exact pinout and each pin’s function from the datasheet.

ST75185CTR is an STMicroelectronics ST7-family microcontroller for cost‑sensitive embedded control. Common application areas include:
- Consumer electronics and home appliances (remote controls, set‑top boxes, microwaves, washers/dryers)
- Automotive interior electronics and body controllers
- Industrial automation and sensors (monitors, small PLC‑like tasks)
- Motor and power control (fan drives, relay interfaces)
- HVAC, metering and utility/smart devices
- General‑purpose embedded control in compact, low‑cost products
