8.7 CapSense
The CapSense system provides a versatile and efficient means
for measuring capacitance in applications such as touch sense
buttons, sliders, proximity detection, etc. The CapSense system
uses a configuration of system resources, including a few
hardware functions primarily targeted for CapSense. Specific
resource usage is detailed in the CapSense component in PSoC
Creator.
A capacitive sensing method using a delta-sigma modulator
(CSD) is used. It provides capacitance sensing using a switched
capacitor technique with a delta-sigma modulator to convert the
sensing current to a digital code.
8.8 Temp Sensor
Die temperature is used to establish programming parameters
for writing flash. Die temperature is measured using a dedicated
sensor based on a forward biased transistor. The temperature
sensor has its own auxiliary ADC.

8.9.1 Current DAC
The current DAC (IDAC) can be configured for the ranges 0 to
32 µA, 0 to 256 µA, and 0 to 2.048 mA. The IDAC can be
configured to source or sink current.
8.9.2 Voltage DAC
For the voltage DAC (VDAC), the current DAC output is routed
through resistors. The two ranges available for the VDAC are 0
to 1.024 V and 0 to 4.096 V. In voltage mode any load connected
to the output of a DAC should be purely capacitive (the output of
the VDAC is not buffered).
Document Number: 001-53304 Rev. *K
8.9 DAC
The CY8C34 parts contain two Digital to Analog Convertors
(DACs). Each DAC is 8-bit and can be configured for either
voltage or current output. The DACs support CapSense, power
supply regulation, and waveform generation. Each DAC has the
following features:
Adjustable voltage or current output in 255 steps
Programmable step size (range selection)
Eight bits of calibration to correct ± 25 percent of gain error
Source and sink option for current output
8 Msps conversion rate for current output
1 Msps conversion rate for voltage output
Monotonic in nature
Data and strobe inputs can be provided by the CPU or DMA,
or routed directly from the DSI
Dedicated low-resistance output pin for high-current mode

8.10 Up/Down Mixer
In continuous time mode, the SC/CT block components are used
to build an up or down mixer. Any mixing application contains an
input signal frequency and a local oscillator frequency. The
polarity of the clock, Fclk, switches the amplifier between
inverting or noninverting gain. The output is the product of the
input and the switching function from the local oscillator, with
frequency components at the local oscillator plus and minus the
signal frequency (Fclk + Fin and Fclk – Fin) and reduced-level
frequency components at odd integer multiples of the local
oscillator frequency. The local oscillator frequency is provided by
the selected clock source for the mixer.
Continuous time up and down mixing works for applications with
input signals and local oscillator frequencies up to 1 MHz.
