CY8C20534-12PVXI

Overview

The CY8C20534-12PVXI is an 8-bit microcontroller from the PSoC 1 family, featuring the M8C processor core. It includes 8 KB of Flash program memory and 512 Bytes of SRAM data storage. The device supports a maximum clock frequency of 12 MHz and operates within a voltage range of 2.4 V to 5.25 V. It provides up to 28 general-purpose I/O pins in the SSOP-28 package. Key peripherals include CapSense capacitive sensing capabilities, I2C slave, and SPI master/slave interfaces.

Feature Summary

• Integrates a low-power CapSense block for configurable capacitive sensing elements including buttons, sliders, touchpads, and proximity sensors.
• Features a powerful M8C Harvard-architecture processor with speeds running up to 12 MHz and low power consumption at high speed.
• Includes flexible on-chip memory with 8 KB flash program storage supporting partial updates and 512 Bytes of SRAM data storage.
• Provides programmable pin configurations with selectable drive modes and access to analog inputs via a common internal analog bus.

Applications

• Capacitive sensing applications such as touch pads and proximity sensors
• Low power embedded control systems requiring industrial temperature range operation
• Systems utilizing I2C or SPI communication interfaces

Procurement Notes

Verify the manufacturer designation as Infineon Technologies, noting that Cypress Semiconductor products are now part of the Infineon portfolio. Confirm the specific ordering suffix PVXI corresponds to the SSOP-28 package and industrial temperature range. Ensure compatibility with existing design files if transitioning from legacy Cypress documentation.

Selection Notes

Select this component when a solution combining 8-bit processing with dedicated capacitive sensing hardware is required. The CY8C20534 variant specifically lacks the digital blocks found in other CY8C20x34 members, relying instead on the CapSense analog system. Consider the 12 MHz clock speed limit and the availability of free development tools like PSoC Designer for implementation.

Part Context

This device belongs to the CY8C20x34 series of PSoC Programmable System-on-Chips. These devices are designed to replace multiple traditional MCU-based components with a single chip. The CY8C20534 is distinguished by its specific memory configuration and lack of digital blocks, focusing on analog and CapSense resources alongside the M8C core.

Replacement Considerations

Consult the official datasheet for cross-referencing within the CY8C20x34 family. Other variants such as CY8C20434 or CY8C20634 may offer different digital/analog block counts but share the same core architecture. Verify package compatibility and electrical specifications before substituting.
