Size and Package of STM8S103F3P6

The STM8S103F3P6 is packaged in a Thin Shrink Small Outline Package (TSSOP) and has 20 pins. The body and lead spacing are smaller than standard SOIC packages. A typical feature of TSSOP is the formation of pins around the packaged chip, which makes it suitable for mounting wiring on PCBs using SMT technology. When using TSSOP package, the parasitic parameters (output voltage disturbance caused by large changes in current) are smaller, so it is suitable for high-frequency applications. This kind of package is more convenient to operate and has higher reliability.

The TSSOP package has the following features:

• Small Pin Spacing: The pin spacing is generally 0.5mm or 0.65mm. Through the design of circuit board copper bars, more devices can be placed on the circuit board with the same area and size.

• Wide Scope of Application: It can be applied to various application fields such as microcontrollers, DSPs, memory chips, and power supply chips.

• High Pin Count: The number of pins is generally around 20 to 64, which can meet certain chip integration requirements.

• Small Package Size: Compared with ordinary Small Outline (SO) packages, its package size is smaller, thickness is thinner, and volume is smaller, making it suitable for packaging of high-density integrated circuits.

• High Performance: It adopts surface mount technology, has good conductivity and corrosion resistance, and can meet special requirements such as high speed, high frequency, miniaturization and so on.

Electrical Characteristics of STM8S103F3P6

Parameter Conditions

Unless otherwise specified, all voltages are referred to VSS.

Minimum and Maximum Limits

The minimum and maximum values are guaranteed under the most adverse conditions, encompassing ambient temperature, supply voltage, and frequencies. These guarantees are established through rigorous production tests performed on 100% of the devices, conducted at an ambient temperature of TA = 25°C and TA = TAmax (as defined by the chosen temperature range).

Values based on characterization results, design simulations, and/or technological characteristics are outlined in the table footnotes and have not undergone production testing. Regarding characterization, the minimum and maximum values pertain to sample assessments and signify the mean value with a range of plus or minus three times the standard deviation (mean±3Σ).

Typical Values

Unless explicitly stated otherwise, standard data are established with TA = 25°C, VDD = 5 V. These values are provided solely as design references and have not undergone testing.

The typical accuracy of ADC values is established through the characterization of a set of samples from a standard diffusion lot across the complete temperature range. In this context, 95% of the devices exhibit an error within the specified value (mean±2Σ).

Typical Curves

Unless specifically indicated, all standard graphs are intended solely as design references and have not been subject to testing.

Absolute Maximum Ratings

Exceeding the specified absolute maximum ratings can result in permanent damage to the device. These ratings solely indicate the limits of stress that the device can endure, and it is not implied that the device will function properly under these conditions. Exposure to conditions at or near the maximum ratings can adversely impact the device's reliability.

The device's mission profile, which outlines its application conditions, adheres to the JEDEC JESD47 Qualification Standard, with extended mission profiles available upon request.

Operating Conditions

VCAP External Capacitor

To achieve stability for the primary regulator, an external capacitor labeled CEXT should be connected to the VCAP pin. It's essential to ensure that the series inductance remains below 15 nH.

Supply Current Characteristics

The current consumption is measured as illustrated in the following picture.

Total Supply Current Consumption in Run Mode

The MCU is placed under the following conditions:

• All peripherals are disabled (clock stopped by peripheral clock gating registers) except if explicitly mentioned.

• All I/O pins in input mode with a static value at VDD or VSS (no load)

Subject to general operating conditions for VDD and TA.
