Debug and programming through SWD or JTAG depending on variant

Key Advantages

Balanced performance, memory, and peripherals for cost-sensitive designs

Mature toolchain and ecosystem around Cortex-M3 for easy development

Flexible peripheral mix to reduce external components

Low power consumption with multiple low-power modes

Strong reliability for industrial and commercial applications

Scalable within the same family for easy product upgrades

Packaging

Vendor package code 642. The CBT6 suffix commonly denotes an LQFP package style with 48 pins

Typical body size for LQFP-48 is about 7 mm by 7 mm with 0.5 mm pitch and gull-wing leads

Pin configuration 48 pins distributed on four sides with standard Cortex-M3 MCU pinout for GPIO and peripherals

Material lead-free RoHS compliant with matte tin finish

Moisture sensitivity generally MSL 3 for LQFP type devices. Follow JEDEC handling and baking guidelines

Thermal characteristics typical junction-to-ambient for LQFP-48 around 65 to 85 C per watt depending on PCB and airflow

Electrical properties typical supply range about 2.0 to 3.6 V. Selected I O lines may be 5 V tolerant in many family members. Exact limits and ESD ratings are defined in the official datasheet

Package or case identification 642 per manufacturer listing. Verify mechanical drawings in the datasheet before PCB layout
