5. Design Problems Engineers Face
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 challenging
Multiple ICs require larger PCBs
PSoC overcomes these three problems
PSoC 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
