S3A7 microcontroller short-circuit
Hello, I try to use a S3A7 microcontroller 64pins and I have some troubles. There is a short-circuit between pin 4 (VBATT) and 5 (VCL). I designed the PCB for tieing VCL to GND through a capacitor and VBATT to VCC. I tested 2 microcontrollers on the same PCB ...

"Undefined Instruction" while trying to debug S3A7
Hello, I back with another issue. Now I try to load a program onto a S3A77C3A01CFB. My Program is almost empty, it consists only of one line to switch on a LED on my board and a while(1) loop. On every other board this works, but on my S3A7 ...

How do I measure MCU power dissipation on Synergy kits and correlate to data sheet values?
... instead, you will find power dissipation metrics correlate with the data sheet values. Without this approach the values will be higher. For example, on the S3A7 the data sheet 5.1mA number for High-Speed mode, Normal operation, at 16 MHz can be as much as 7.3 mA (also ...
