Why do you prefer mcu’s from Silab over say, the PIC32’s from microchip? The extended interrupt handler provides 16 interrupt sources into the CIP as opposed to 7 for the stan- dardallowing numerous analog and digital peripherals to interrupt the controller.

The daughter card is pre-loaded with a game that requires you to mimic LED light sequences by entering the sequence via the capacitive touch sense pads.

The first is that by increasing the switch sensitivity, the switches can be used for proximity detection as well as being used as a standard switches. Once cleared to logic 0, a Flash bit must be erased to set it back to logic 1. The development kit contents may also be used to program and debug the device on the production PCB using the appropriate connections for the program- ming pins USB0 core registers and their indirect addresses. Why does EP1 allow faster transfer than EP2?

A capacitive touch sense solution is easily implemented on many Silicon Labs MCUs and offers many advantages including a low BOM cost, small Flash requirements less than byteslittle MCU overhead, low power requirements and does not require the MCU to use a precise voltage source. An interrupt will occur if enabled when either TI0 or RI0 is set. Fortunatelly all pins are usable. The sensitivity of the switches is also easily configurable in firmware which enables two useful features.


External RC Example network is used as an external oscillator source for the MCU, the circuit should be configured as shown in Figure Silicon Labs Capacitive Touch Sense Touch sensitive switches are found in a variety of consumer products including home appliances, MP3 players and cell phones.

The capacitor should be no greater than pF; however for very small capacitors, the total capacitance may be dominated by parasitic capacitance in the PCB layout. This bit sets the priority of the Timer 3 interrupt. This register serves as a second accumulator for certain arithmetic operations. MHz, disabling the Flash one-shot will increase system power consumption.

All other trademarks are the property of their respective owners. Flash bytes would typically be erased set to 0xFF before being reprogrammed. Touching this trace with a finger creates a change in capacitance, which is detectable using a variety datashewt techniques. Elcodis is a trademark of Elcodis Company Ltd. The Datasheft, data conversion modes, and window detector are datasheeh configurable under software control via the Special Function Registers shown in Figure These bits select the response time for Comparator1.

Comparator1 Negative Hysteresis Control Bits.

Typical C2 Pin Sharing If operating from the external oscillator, switch to the internal oscillator during Flash write or erase operations. And I very very darasheet, being able to go from idea to a functioning PCB not taking into account designing the PCB in under a day is extremely awesome! Silicon Labs’ capacitive touch sense solution uses the switch capacitor as part of a simple RC resistor-capacitor relaxation oscillator. Byte Sectors 0x 9.


Each of the serial buses is fully implemented in hardware and makes extensive use of the CIP’s interrupts, thus requiring very little CPU intervention. CFGQ datasheet and specification datasheet.

Suspend signaling is detected on the bus. C2 Interface Figure Disable all SMB0 interrupts. These are general purpose flags for use under software control. Any of the following may be selected as the positive input: So I fired up eagle and designed a breakout board for this chip and in 4 hours Eatasheet had the board ready to be used. In this mode, the ddatasheet packet size is halved and the FIFO may contain two packets at a time.

ACK cycle in this mode. Double-buffering disabled for the selected IN endpoint.

Two compar- ator outputs may be routed to a Port pin if desired: The crystal should be placed as close as possible to the XTAL pins on the device. SAR Conversion clock requirements darasheet given in Table The CF is a nice chip it needs only 4 Capacitors to work.

Flash Error system reset will be generated. Interrupt Register Descriptions The SFRs used to enable the interrupt sources and set their priority level are described below. I’ve added 2 resistor to be able to share the c2ck programming pin with a reset button. Home – IC Supply – Ratasheet. This bit sets the masking of the SMB0 interrupt. Last reset was a USB reset; Write:
