What sets this part apart in the 8051 space is the integrated programmable analog: a 16-channel 12-bit ADC and two 8-bit DACs, plus CapSense touch-sensing and an LCD controller, all in a single 48-pin SSOP package. That analog front-end saves a separate data-converter IC and its support passives for sensor interfaces, control loops, or human-machine panels. ## Where the 50 MHz and analog matter for your BOM The 50 MHz clock is the practical ceiling for this 8051 — at that speed, flash wait states need to be configured correctly in the PSoC Creator project or the first branch instruction will hard-fault. The 12-bit ADC with 16 multiplexed channels lets you sample multiple sensor inputs without an external mux; the two 8-bit DACs can generate analog setpoints or audio tones. The CapSense peripheral handles capacitive touch buttons and sliders directly, eliminating a dedicated touch controller IC. For a control panel or industrial sensor node, this part can replace an MCU plus an external ADC plus a touch chip — three ICs collapsed into one 48-pin package. The 48-SSOP package (0.295-inch body width, 7.50 mm) is a fine-pitch but hand-reworkable gull-wing — a hot-air station can lift it cleanly if you preheat the board to 100°C and work the flux under the leads. MSL 3 out of the bag — bake before reflow if the moisture-barrier bag has been open past the floor-life window. ## Lifecycle and sourcing posture No official second-source alternate is listed, but the PSoC Creator toolchain supports the whole CY8C34xx family, so a migration to a higher-density sibling within the series is straightforward if the BOM ever needs a Flash or I/O upgrade.","metaTitle":"CY8C3445PVI-094 Infineon PSoC 3 MCU, 8051 50MHz, 32KB Flash","metaDescription":"CY8C3445PVI-094 PSoC 3 8-bit MCU with 8051 core at 50MHz, 32KB Flash, 4Kx8 RAM, CapSense, 12-bit ADC, -40 to 85°C.
