This section provides the block-level description of the PSoC 4000 Pioneer Kit, as illustrated in
Figure 4-4 .
Figure 4-4. Block Diagram
PSoC 4 is a new generation of programmable system-on-chip devices from Cypress for embedded
applications. The PSoC 4000 family is the smallest member of the PSoC 4 platform with CapSense,
TCPWM, I
2
C master or slave, and up to 20 GPIOs support. PSoC 4000 is a cost-optimized, entry-
level PSoC4 device targeted as socket replacements for obsolete and/or proprietary 8-bit and 16-bit
MCUs. PSoC 4000 with its ARM Cortex-M0 core brings 32 CapSense and programmable peripher-
als.
The kit features an onboard PSoC 5LP, which communicates through the USB to program and
debug the PSoC 4 using SWD. The PSoC 5LP also functions as a USB-I
2
C bridge and USB-UART
bridge. It can also be used to develop PSoC 5LP based applications (see Developing Applications
for PSoC 5LP on page 130 ).
The kit includes an RGB LED, a status LED, and a power LED. The RGB LED is connected to the
PSoC 4, and the status LED is connected to the PSoC 5LP. This kit also includes a Reset button that
connects to the PSoC 4 XRES, a CapSense proximity header, and a 6x5 elements Trackpad board
that is Arduino shield-compatible and can be used to develop touch-based applications. The PSoC 4
pins are brought out onto headers J1 to J4 on the kit to support Arduino shields. The PSoC 5LP pins
are brought out onto header J8 to enable using the onboard PSoC 5LP to develop custom applica-
tions.
The PSoC 4000 Pioneer Kit can be powered from the USB Mini-B, the Arduino compatible header,
an external power supply, or an optional coin cell battery. The input voltage is regulated by a low
drop out (LDO) regulator to 3.3 V. You can select between VBUS (5 V) and 3.3 V by suitably plug-
ging the jumper onto the voltage selection header J9. VDD can also be supplied by a coin cell bat-
tery placed in the BT1 coin cell holder. The voltage supplied by the coin cell is directly connected to
the VDD line through a diode, D11. Make sure that VDD does not exceed the device's VDD specifi-
cation (1.8 V to 5.5 V).
