PSC3M3FDS2ACQ1

PSC3M3FDS2ACQ1 is an Infineon Technologies PSOC Control C3 Entry Line microcontroller for motor control and digital power, built around a 100 MHz Arm Cortex-M33 core with 256 KB Flash and 64 KB SRAM in an E-LQFP-64 package. It provides a 12-bit SAR ADC running at 6 Msps across 16 channels, a CORDIC math coprocessor, the MOTIF Hall and encoder interface, six serial communication blocks (SCB), and PSA L2 security. The benefit is the C3 control feature set at Entry Line positioning: hardware math and motor interfaces that keep field-oriented control responsive, at a lower core and ADC rate than the 180 MHz, 12 Msps Main Line M5 offered in the same 64-pin leaded package. For buyers, M3 versus M5 is the selection split when memory is already fixed at 256 KB: pick the M3 for cost-sensitive single-drive designs, and the M5 when the control loop needs the faster core and ADC. Evidence: the Infineon Entry Line family datasheet 002-36422 lists PSC3M3FDS2ACQ1 in E-LQFP-64 with active and preferred status and a -40 °C to +115 °C operating range.
