ESD (electrostatic discharge) sensitive device.
Charged devices and circuit boards can discharge
without detection. Although this product features
patented or proprietary protection circuitry, damage
may occur on devices subjected to high energy ESD.
Therefore, proper ESD precautions should be taken to
avoid performance degradation or loss of functionality.

reflect statistical variations and worst cases. Consequently, it is

Switching Characteristics specify how the processor changes its
signals. Circuitry external to the processor must be designed for
compatibility with these signal characteristics. Switching char-
acteristics describe what the processor will do in a given
circumstance. Use switching characteristics to ensure that any
timing requirement of a device connected to the processor (such

ABSOLUTE MAXIMUM RATINGS
Stresses greater than those listed in Table 11 may cause perma-
nent damage to the device. These are stress ratings only;
functional operation of the device at these or any other condi-
tions greater than those indicated in the operational sections of
this specification is not implied. Exposure to absolute maximum
rating conditions for extended periods may affect device
reliability.

as memory) is satisfied.
Timing Requirements apply to signals that are controlled by cir-
cuitry external to the processor, such as the data input for a read
operation. Timing requirements guarantee that the processor
operates correctly with other devices.
Core Clock Requirements
The processor’s internal clock (a multiple of CLKIN) provides
the clock signal for timing internal memory, processor core, and
serial ports. During reset, program the ratio between the proces-
sor’s internal clock frequency and external (CLKIN) clock
frequency with the CLK_CFG1–0 pins.
The processor’s internal clock switches at higher frequencies
than the system input clock (CLKIN). To generate the internal
clock, the processor uses an internal phase-locked loop (PLL,
see Figure 4 ). This PLL-based clocking minimizes the skew
between the system clock (CLKIN) signal and the processor’s
internal clock.
