CY8C20566A-24PVXIT

Application Specific Microcontrollers Overview

The CY8C20566A-24PVXIT is an 8-bit microcontroller from the PSoC 1 family, featuring an M8C CPU core with a maximum clock frequency of 24 MHz. It integrates CapSense technology for capacitive sensing and includes an Immersion TS2000 Haptics controller for ERM drive control. The device operates within a voltage range of 1.71 V to 5.5 V and supports up to 34 I/O pins in its SSOP-48 package. Memory resources include 8 kB of Flash program memory and 1 kB of SRAM data memory.

Application Specific Microcontrollers Feature Summary

• M8C CPU core operating at up to 24 MHz
• Integrated CapSense block for capacitive sensing applications
• Immersion TS2000 Haptics controller supporting up to 14 effects
• I2C slave and SPI master/slave communication interfaces
• Three 16-bit programmable timers and watchdog/sleep timers

Application Specific Microcontrollers Applications

• Capacitive touch sensing interfaces including buttons, sliders, and touchpads
• Haptic feedback systems using Eccentric Rotating Mass (ERM) motors
• Low-power embedded control systems requiring configurable analog and digital peripherals
• Devices requiring In-System Serial Programming (ISSP) capabilities

Application Specific Microcontrollers Procurement Notes

Verify the specific ordering suffix 'T' indicates tape-and-reel packaging if required by assembly equipment. Confirm the manufacturer designation as Infineon Technologies or Cypress Semiconductor depending on the production era. Ensure compatibility with the SSOP-48 package dimensions for PCB layout. Check for RoHS compliance status in the latest datasheet revision.

Application Specific Microcontrollers Selection Notes

Select this component when both CapSense functionality and haptic feedback control are required in a single chip. The 8 kB Flash and 1 kB SRAM sizes suit moderate complexity applications. The 24 MHz clock speed provides sufficient processing power for real-time sensor scanning and motor control loops. Consider the SSOP-48 package availability against alternative QFN options if space constraints differ.

Application Specific Microcontrollers Part Context

This part belongs to the CY8C20xx6A series of PSoC 1 devices. It shares architectural similarities with the CY8C20336H and CY8C20446H families but utilizes a different package configuration. The inclusion of the TS2000 Haptics controller distinguishes it from standard CapSense-only variants in the same processor family.

Application Specific Microcontrollers Replacement Considerations

Direct pin-compatible replacements may be limited due to the specific haptics integration. Review CY8C20536A or CY8C20446A variants for functional equivalence if haptic features are not utilized. Verify that any substitute maintains the 24 MHz clock capability and SSOP-48 footprint.
