Freescale Semiconductor
Preliminary
Electrical Characteristics
Table 10
gives details of the applied voltages to the i.MX31/i.MX31L Core Supply I/O versus the
frequencies of the ARM11 core.
Table 11
provides information for interface frequency limits. For more details about clocks characteristics,
see
Section 4.3.8, “DPLL Electrical Specifications
”
on page 82
.
Table 12
provides the DC absolute maximum operating conditions.
CAUTION
Stresses beyond those listed under
“DC Absolute Maximum Operating
Conditions,”
(
Table 12
) may cause permanent damage to the device. These
are stress ratings only. Functional operation of the device at these or any
other conditions beyond those indicated under “recommended operating
conditions” is not implied. Exposure to absolute-maximum-rated conditions
for extended periods may affect device reliability.
6
Recommended maximum OVDD operating voltage is 3.1 V for GPIO in either slow or fast mode. Switching duty cycles must
be limited to a cumulative duration of 1 year or less (20% duty cycle for a 5yr rated part) to sustain a MAX OVDD operating
voltage of 3.3V without significant device degradation. A switching cycle is defined as the period of time that the pad is powered
to OVDD and actively switching. Switching cycles exceeding this limit may affect device performance or cause permanent
damage to the device.
7
The performance at 1.8 V of GPIO devices that are operated at 3.3 V over an extended period of time (for example. 2 years or
longer at a 20% duty cycle) is not guaranteed. Reliability degradation may render the device too slow or inoperable.
8
Overshoot and undershoot conditions (transitions above OVDD and below OVSS) on switching pads must be held below 0.6 V,
and the duration of the overshoot/undershoot must not exceed 10% of the system clock cycle. Overshoot/undershoot must be
controlled through printed circuit board layout, transmission line impedance matching, signal line termination, or other methods.
Non-compliance to this specification may affect device reliability or cause permanent damage to the device.
9
For normal operating conditions, PLLs’ and core supplies must maintain the following relation: PLL
≥
Core – 100 mV. In other
words, for a 1.6 V core supply, PLL supplies must be set to 1.5 V or higher.
10
Providing a voltage that is lower than specified does not prevent the fuses from being blown if attempting to program a fuse.
