It packs 32 KB of Flash program memory, 4K x 8 of RAM, and 1K x 8 of EEPROM — enough for a moderate firmware image with calibration constants stored separately. The 48-pin SSOP package gives you 25 general-purpose I/O lines, plus a 16-channel 12-bit ADC and a single 8-bit DAC on the analog side. The internal oscillator keeps the BOM lean; no external crystal needed for most control loops. What sets this part apart in the PSoC 3 family is the integrated CapSense peripheral — it handles capacitive touch sensing without a separate controller IC, which simplifies the PCB layout and reduces component count for panel interfaces. The connectivity set covers EBI/EMI, I²C, LINbus, SPI, and UART/USART, so it can talk to serial sensors, memory, and host controllers on the same bus. ## Industrial temperature range and supply flexibility Rated for -40°C to 85°C ambient. Supply voltage spans 1.71 V to 5.5 V. ## Lifecycle and sourcing — active, no LTB concern The CY8C3245PVI-134 carries an Active product status and is ROHS3 compliant. There is no last-time-buy notice or phase-out window on record, so it is safe to qualify into a new BOM today. The part ships in tubes; if your pick-and-place line prefers tape, verify the reel option with your distributor before ordering production quantities.","metaTitle":"CY8C3245PVI-134 Infineon PSoC 3 MCU, 8-Bit 8051, 50MHz","metaDescription":"CY8C3245PVI-134 PSoC 3 MCU: 8-bit 8051 core at 50MHz, 32KB Flash, 4K x 8 RAM, CapSense, industrial temp -40°C to 85°C.

The CY8C29466-24PVXI is an older PSoC 1 part with an M8C core at 24 MHz and different analog resources — not a pin-compatible drop-in.
