Key Advantages

Robust operation across automotive and industrial temperatures

Runs from 5 V supplies while also supporting 3 V, simplifying legacy and mixed-voltage designs

Integrated CAN and LIN for vehicle and industrial networks

On-chip EEPROM for non-volatile data logging without external memory

Built-in safety blocks (WDT, POR, BOD) for reliable, fail-safe systems

Low-cost, low-power 8-bit platform with strong peripheral set

Flexible clocking with internal RC and external crystal options

Long-life STM8S platform with broad ecosystem and tooling

Packaging

Shipment type: Tape and Reel (TR) for automated SMT assembly

Package case: 48-LQFP (7x7 mm) square body, no exposed thermal pad

Pin count and layout: 48 leads, typical 0.5 mm pitch, 38 configurable GPIO

Materials: epoxy mold compound and copper leadframe, lead-free matte tin finish

Size and thickness: 7x7 mm body, typical thickness ~1.4 mm (check datasheet for exact values)

Thermal characteristics: ambient rating -40°C to +125°C, typical junction-to-ambient thermal resistance depends on PCB (refer to datasheet), no exposed pad

Electrical properties summary: 2.95 V to 5.5 V supply, up to 24 MHz, integrated ADC and communication interfaces

Moisture sensitivity: JEDEC MSL per ST datasheet (commonly MSL 3; confirm in datasheet)

Lifecycle

Status: Active and widely used in production. Not nearing discontinuation based on current market status.

Recommended equivalents and alternatives:

- STM8S208CBT6TR: Same family and package in tape and reel with alternate suffix (check temperature and finish codes)

- STM8S208CBT6: Same device family and package, different packing option

- STM8S208C8T6TR: Same package with 64 KB Flash (reduced memory)

- STM8S207CBT6: Close alternative if CAN is not required, same package family (verify pinout and peripheral set)

- STM8S208RBT6: Higher pin-count variant for more I/O (not pin-compatible; feature-compatible)

- 32-bit migration options: STM32G0 or STM32F0 series for higher performance while keeping low cost (not pin-compatible)

Note: Exact pin-for-pin compatibility and suffix meanings must be confirmed against the datasheet. If you need a precise drop-in or a vetted alternative, contact our sales team via the Y-IC website for expert guidance and the latest lifecycle data.
