PSoC 1 with 8 KB Flash and 24 MHz M8C core
It includes an internal oscillator, a 10-bit ADC, and peripherals such as LVD, POR, PWM, and WDT.
28 I/O, I²C and SPI, internal oscillator
With 28 I/O lines and serial interfaces for I²C and SPI, this MCU can handle sensor readout, simple display control, and actuator management without external glue logic. The 10-bit ADC provides basic analog measurement capability for voltage, current, or temperature sensing.
1.71 V supply – low-voltage operation
The supply voltage range down to 1.71 V allows direct battery operation from a single Li-ion or two alkaline cells without a boost regulator. This is a key differentiator versus many 8-bit MCUs that require a minimum of 2.7 V or higher.
