Typical applications include digital power supplies (SMPS and power factor correction), brushless DC and PMSM motor control, and audio or sensor signal conditioning, where the 40 MIPS throughput and hardware DSP multiply-accumulate operations maintain loop bandwidth under load. Design consideration: the 28-SOIC package requires careful decoupling (100 nF ceramic at VDD/AVDD) and, because VDD and core supply share the 3.3 V rail in this family, verify Brown-out and POR settings for reliable startup.

Typical applications include digital power supplies and lighting control, motor control, audio signal processing, and industrial sensors where the combination of DSP math, general-purpose I/O, and on-chip analog reduces system BOM count. The 6x6 mm QFN-S package supports compact surface-mount designs in industrial and portable equipment. A key design consideration: the device operates only from a 3.0 V to 3.6 V supply, so 5 V systems require level shifting or a local 3.3 V regulator; plan decoupling on both VDD pins and reference the analog front end carefully to preserve signal integrity.

A key design consideration: keep ICSP (PGECx/PGEDx) programming trace lengths short, and always use a matched PGECx/PGEDx pair - if PGEC2 carries ICSPCLK, ICSPDAT must connect to PGED2. All VDD/VSS pins must be connected and decoupled.
