PSC3P5FDS2LGQ1

PSC3P5FDS2LGQ1 is an Infineon Technologies PSOC Control C3 Main Line microcontroller for compact digital power designs, built around a 180 MHz Arm Cortex-M33 core with 256 KB Flash and 64 KB SRAM in a VQFN-48 package. It provides a 12-bit 12 Msps SAR ADC with 12 channels and four serial communication blocks (SCB), with PSA L2 security applying to this 256 KB device; as the P5 power variant it has no CORDIC coprocessor and no MOTIF motor interface. The benefit is the full 256 KB Main Line power configuration in the family's smallest package, suited to compact chargers, auxiliary power stages, and dense converter boards where 12 analog channels and four serial blocks are enough. For buyers, the comparison against the 64-pin P5 code is channel and interface count, not memory: both carry 256 KB Flash, but the 48-pin form drops to 12 ADC channels and four SCB. Evidence: Infineon datasheet 002-36032 lists PSC3P5FDS2LGQ1 in VQFN-48 with active and preferred status and a -40 °C to +115 °C operating range. Selection advice: order the full PSC3P5FDS2LGQ1XQLA1 code including the XQLA1 suffix, which differs from the XQSA1 suffix on earlier PSC3 listings.
