Re-engineering Temperature Sensing
Every sensor requires a special analog IC, which adds cost
Companies are re-engineering older products to reduce costReplacing older analog ICs as they become obsolete
Consolidating platforms to reduce PCB variants
Designing new products in smaller enclosures
This is a great opportunity to reduce your BOM, manufacturing cost, and time-to-market for your product portfolio
Market Vision: To define the market opportunity. Presents compelling data and end product photos relevant to the local market. Should use compelling photographs of actual PSoC products.

Terms You Will Hear TodayTemperature Sensors − convert temperature to an analog signalThermocouple (e.g., type K, J, T): generates ~40 µV/ oC, requires ADC and a reference Temperature Sensor
RTD (Resistance Temperature Detector): changes ~0.387 Ω/ °C, requires current source and ADC
Thermistor: changes ~400 Ω/ °C at room temperature, requires voltage source and ADC
Temperature diode: ~250 µV/ oC, requires current source and ADC
Current/Voltage Sources for SensorsICs that generate precise voltage or current supplies for sensors
IDAC (Current Output Digital to Analog Converter)IC that generates programmable current sources for sensors
ADC (Analog to Digital Converter)IC that converts analog sensor signals, such as Temperature Sensor outputs, to digital for a microcontroller

Design Problems Engineers Face
Traditional Approach and Challenges: To present the traditional approach and the challenges engineers will face when using it to realize the Market Vision. Ends with a one-sentence segue clearly stating the benefit of the Cypress solution.
1. Temperature-sensing system requires multiple ICs ($)AFEs for each sensor
A microcontroller with firmware algorithms to convert and correct sensor outputs
and to communicate the temperature to other devices (e.g., displays)
2. Multiple-sensor interface design is complicated Single-IC obsolescence may cause redesign
PCB designs change every time a chip or wire changes
Sourcing ICs from multiple vendors complicates and slows development
3. Fitting products into small enclosures is challengingMultiple ICs require larger PCBs
PSoC overcomes these three problemsPSoC one-chip solution supports multiple Temperature Sensors (simultaneously)
PSoC Sensor Components provide algorithms and firmware for accurate sensor conversion
PSoC integrates the microcontroller and analog ICs with ADC and IDAC Components
PSoC enables fast, easy design modifications without PCB changes
PSoC simplifies design by integrating many ICs in a single chip
PSoC reduces PCB size and PCB layers, enabling smaller enclosures
PSoC is an easy-to-use, low-cost, one-chip temperature-sensing solution
Each design has different ICs and PCBs
Multiple AFE ICs
