• Manufacturer Part Number: cy8c20180
• Description: Capsense Express -8 Configurable Ios
• Manufacturer: Cypress Semiconductor Corporation.

The CapSense Analog System
The CapSense analog system contains the capacitive sensing
hardware. which supports CapSense Successive Approximation
(CSA) algorithm.This hardware performs capacitive sensing and
scanning without external components. Capacitive sensing is
configurable on each pin.
Additional System Resources
System resources provide additional capability useful to
complete systems. Additional resources are low voltage
detection and power on reset (POR).

An internal 1.8V reference provides a stable internal reference
so that capacitive sensing functionality is not affected by minor

CY8C201xx Register Reference
Higher storage temperatures reduce
data retention time. Recommended
storage temperature is +25°C ± 25°C
(0°C to 50°C). Extended duration
storage temperatures above 65°C
degrade reliability.
