Overview
The CY8C21534B-24PVXI is an 8-bit microcontroller within the PSOC®1 CY8C21xxx series, manufactured by Infineon Technologies. It features an M8C core operating at a maximum frequency of 24MHz. The device includes 8KB of Flash program memory and 512 bytes of RAM. It integrates 28-channel 8-bit analog-to-digital converters and supports I2C, SPI, and UART/USART interfaces. Powered between 2.4V and 5.25V, it operates from -40°C to +85°C in a 28-pin SSOP package.
Feature Summary
- Integrates CapSensePLUS technology for capacitive touch sensing capabilities
- Combines digital processing with programmable analog blocks on a single chip
- Includes internal oscillator for clock generation without external components
- Supports standard serial communication protocols including I2C, SPI, and UART
Applications
- Capacitive touch interface implementations
- Mixed-signal embedded control systems
- Battery-powered devices requiring low power operation
- Industrial sensor nodes with analog signal conditioning
Procurement Notes
Verify the manufacturer designation as Infineon Technologies, reflecting the acquisition of Cypress Semiconductor Corp. Confirm the specific suffix PVXI corresponds to the 28-SSOP package and industrial temperature range. Ensure compatibility with PSoC Designer or Creator software tools for programming. Check for RoHS compliance documentation provided by the supplier.
Selection Notes
Select this component when both digital control and analog signal processing are required in a compact form factor. The integrated CapSensePLUS feature eliminates external touch controller hardware. Compare against CY8C21534 variants if different speed grades or packaging options are needed. Consider the 28-channel ADC resolution for precision measurement applications.
Part Context
This part belongs to the PSOC®1 family, which merges a processor with configurable analog and digital peripherals. The CY8C21534B variant specifically enhances the original CY8C21534 with improved CapSense functionality. It serves as a system-on-chip solution for applications needing mixed-signal processing without complex external circuitry.
Replacement Considerations
The CY8C21534-24PVXI is a predecessor model with similar specifications but lacks the 'B' revision enhancements. Verify pinout compatibility before substitution. Other members of the CY8C21xxx family may offer different I/O counts or memory sizes.
