Device Structure

Built around a 32-bit RISC CPU (ARM Cortex-M0) with on-chip flash and RAM, multiple digital and analog peripherals, communication interfaces, and an internal oscillator. Housed in a plastic 48-lead LQFP package for surface mounting.

Performance Characteristics

Operates at up to 48MHz clock frequency providing efficient processing for real-time embedded control. Integrated 12-bit ADC allows fast and precise analog signal acquisition, and the 12-bit DAC enables analog signal output. The device features multiple communication channels, and uses low supply voltage for reduced power consumption.

Application Environments

Ideal for consumer electronics, industrial controls, automotive subsystems, communication equipment, home appliances, medical devices, and other embedded control systems requiring moderate computing power, mixed-signal capabilities and multiple interfaces in a compact form factor.

Selection Guidelines

Choose this model for applications that require:

Medium Flash and RAM memory

ARM Cortex-M0 performance

Multiple analog and digital peripherals

Up to 37 general-purpose I/Os

Compact, robust LQFP-48 packaging

Low voltage operation (down to 1.65V)

Broad communication protocol support (CAN, I2C, LIN, UART, SPI, IrDA)

ROHS and REACH environmental compliance

Verify the microcontroller’s peripherals and memory sizes match your application requirements.

Usage Considerations

Adhere to the supply voltage range (1.65V to 3.6V)

Respect the absolute maximum ratings for safe operation

Ensure correct PCB layout to manage 48-pin LQFP package

Account for moisture sensitivity (MSL 3 – keep dry before soldering)

Use proper ESD precautions when handling the device

Flash programming tools and debuggers must support ARM Cortex-M0

Potential Equivalent/Replacement Models

You can consider the following equivalent or alternative models:

STM32F098RCT6 (larger package, same core/peripherals)

STM32F091CCT6 (similar features, different communication interfaces)

STM32F103C8T6 (Cortex-M3, higher performance but different core)
