MHz. The same divisor will be from 2 to 16 when the PLL2 is running at 432 MHz, giving an
operating frequency in the range from 216 to 27 MHz.
The GPS baseband clock will be derived from the MCLK clock with a divider, internal to the
subsytem, by 1, 2,3 or 4, under ARM11 control. RFCLK is the clock received from the RF
front-end chip.
Touchscreen controller/ADC
STA2065 embeds a 4-wire Touch Screen Controller. The Touch Screen Controller main
characteristics are:
●
●
●
●
●
●
●
The ADC of the Touch Screen Controller can be also used for the conversion of external
analog signals. In this case the ADC has a 10-bit resolution (its native resolution).
Multisupply IO ring
STA2065 has multivoltage IOs capable of supporting 1.8V, 2.5V or 3.3V interfaces. The
rings are defined as follows:
●
●
●
●
●
The default voltage applied to each ring will be at reset time will be:
●
●
●
●
●
The “Always ON” ring remains separated as in the current STA2065 and supplied by V
Active Window Clip
Movements Tracking
12-bit SAR ADC resolution when used for Touch screen (with averaging)
Measurement oversampling from 2 to 8
Up to 128 coordinates FIFO, with programmable FIFO threshold
ADC minimum conversion time of 1 μs
Capability to support 4 additional analog inputs for auxiliary functions like battery
voltage monitoring and accessory control.
