Specifications of CY8C5487LTI-007

• Lead Free Status / RoHS Status: Compliant

Vcca. Output of analog core regulator and input to analog core.
Requires a 1 µF capacitor to Vssa. Regulator output not for
external use.
Vccd. Output of digital core regulator and input to digital core.
The two Vccd pins must be shorted together, with the trace
between them as short as possible, and a 1 µF capacitor to Vssd;
see
use.
Vdda. Supply for all analog peripherals and analog core
regulator. Vdda must be the highest voltage present on the
device. All other supply pins must be less than or equal to
Vdda.
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. Each
Vddio must be tied to a valid operating voltage (1.71 V to 5.5 V),
and must be less than or equal to Vdda. If the I/O pins associated
with Vddio0, Vddio2 or Vddio3 are not used then that Vddio
should be tied to ground (Vssd or Vssa).
XRES (and configurable XRES). External reset pin. Active low
with internal pullup.
4. CPU
4.1 ARM Cortex-M3 CPU
The CY8C54 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.
