Vddd. Supply for all digital peripherals and digital core regulator.
Vddd must be less than or equal to Vdda.
Vssa. Ground for all analog peripherals.
Vssb. Ground connection for boost pump.
Vssd. Ground for all digital logic and I/O pins.
Vddio0, Vddio1, Vddio2, Vddio3. Supply for I/O pins. See
pinouts for specific I/O pin to Vddio mapping. Vddio must be less
than or equal to Vdda.

4.1 ARM Cortex-M3 CPU
The CY8C52 family of devices has an ARM Cortex-M3 CPU
core. The Cortex-M3 is a low power 32-bit three-stage pipelined
Harvard architecture CPU that delivers 1.25 DMIPS/MHz. It is
intended for deeply embedded applications that require fast
interrupt handling features.
