Electrical Specifications
This section presents the DC and AC electrical specifications of the enCoRe III LV device. For the most up to date electrical
specifications, check the latest data sheet by visiting the web at http://www.cypress.com.
Specifications are valid for 0°C ≤ T_A ≤ 70°C and T_J ≤ 85°C as specified, except where noted.
Refer to Table 20 on page 21 for the electrical specifications on the internal main oscillator (IMO) using SLIMO mode.

The allowable CPU operating region for 12 MHz has been extended down to 2.7V from the original 3.0V design target. The customer's
application is responsible for monitoring voltage and throttling back CPU speed in accordance with Figure 10 when voltage
approaches 2.7V. Refer to Table 18 for LVD specifications. Note that the device does not support a preset trip at 2.7V. To detect Vdd
drop at 2.7V, an external circuit or device such as the WirelessUSB LP - CYRF6936 must be employed; or if the design permits, the
nearest LVD trip value at 2.9V can be used.
