3 Electrical Characteristics
This section contains the electrical specifications and timing diagrams for the i.MX1 processor.
3.1 Maximum Ratings
Table 4 provides information on maximum ratings which are those values beyond which damage to the
device may occur. Functional operation should be restricted to the limits listed in Recommended Operating
Range Table 5 on page 23 or the DC Characteristics table.

1 _{A typical application with 30 pads simultaneously switching assumes the GPIO toggling and instruction fetches from the ARM}®
core-that is, 7x GPIO, 15x Data bus, and 8x Address bus.
2 _{A worst-case application with 70 pads simultaneously switching assumes the GPIO toggling and instruction fetches from the}
ARM core-that is, 32x GPIO, 30x Data bus, 8x Address bus. These calculations are based on the core running its heaviest OS
application at MHz, and where the whole image is running out of SDRAM. QVDD at V, NVDD and AVDD at 3.3V, therefore,
180mA is the worst measurement recorded in the factory environment, max 5mA is consumed for OSC pads, with each toggle
GPIO consuming 4mA.
3.2 Recommended Operating Range
Table 5 provides the recommended operating ranges for the supply voltages and temperatures. The i.MX1
processor has multiple pairs of VDD and VSS power supply and return pins. QVDD and QVSS pins are
used for internal logic. All other VDD and VSS pins are for the I/O pads voltage supply, and each pair of
VDD and VSS provides power to the enclosed I/O pads. This design allows different peripheral supply
voltage levels in a system.
Because AVDD pins are supply voltages to the analog pads, it is recommended to isolate and noise-filter
the AVDD pins from other VDD pins.
BTRFVDD is the supply voltage for the Bluetooth interface signals. It is quite sensitive to the data
transmit/receive accuracy. Please refer to Bluetooth RF spec for special handling. If Bluetooth is not used
