8051 core at 50 MHz — what that buys you in a mixed-signal controller
The CY8C3445LTI-078 is an Infineon PSoC 3 device built around an 8051 CPU core running at 50 MHz. This is the part you pick when a design needs a single-chip solution for sensor measurement, capacitive touch buttons, and a small display — without adding separate ADC, touch controller, and LCD driver ICs.
Industrial temperature range — fits factory-floor and outdoor gear
The internal oscillator keeps the clock running without an external crystal, saving two pins and a few cents on the BOM.
Active lifecycle — still a current-production part
For a repair bench or a new design, this means you can source it without worrying about a looming EOL.
