Reduce Your Manufacturing Cost and Time-to-Market

PSoC 3 and PSoC 5LP For Temperature Sensing

001-76565 Rev *H


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
