PSoC Creator 2.1 Component Pack 4 (CP4) adds 6 new components to Cypress growing library of inbuilt virtual chips or components. To those not familiar with Component Packs they are component-only enhancements to PSoC Creator. So what are these new components?

1. SMBus and PMBus
These complete Cypress power supervision portfolio for PSoC 3 and PSoC 5, by adding SMBus and PMBus slave communication capability to PSoC. Learn more about PSoC Power Supervision solution at http://www.cypress.com/go/PowerSupervision.

2. Debouncer
This is probably going to be the most-used component out of all six new releases because it is the easiest and best way to debounce and edge-detect switch inputs to your system, without using your CPU.
3. Glitch Filter
The hardware glitch filter removes unwanted pulses from a digital signal, and is a frequently used function in digital designs. The Glitch Filter v2.0 is a complete re-design from its previous version which was available as a PSoC Creator concept component.
For more information on switch-debouncing and glitch-filtering, see AN60024.

4. RTD Calculator
5. Thermistor Calculator
6. Thermocouple Calculator
These three new components add easy-to-implement temperature-sensing capability to PSoC Creator s component library. Find out more about temperature-sensing with PSoC 3 and PSoC 5 through the suite of application notes available:
· AN70698 - Temperature Measurement with RTDs
· AN66477 - Temperature Measurement with Thermistor
· AN75511 - Temperature Measurement with Thermocouples

CP4 also provides an update to the I2C Master/Multi-Master/Slave component, with the addition of an I2C bus multiplexing feature, besides for some minor tweaks.
I have already installed CP4 on my system especially for the debouncer. Many of you may want one or more of these new components, or the more robust I2C. To get all of these, please download Component Pack 4.
