CY8C21534-24PVXI

Overview

The CY8C21534-24PVXI is an 8-bit microcontroller IC from the PSoC 1 CY8C21xxx series, manufactured by Infineon Technologies (formerly Cypress Semiconductor). It features an M8C core processor operating at a maximum speed of 24MHz. The device includes 8KB of Flash program memory and 512 bytes of RAM. It supports a supply voltage range of 2.4V to 5.25V and operates within a temperature range of -40°C to 85°C. The component is housed in a 28-SSOP package with 24 programmable I/O lines.

Feature Summary

• Integrates configurable analog and digital peripherals within a mixed-signal array architecture for system-level flexibility.
• Supports standard communication interfaces including I2C, SPI, and UART/USART for versatile connectivity.
• Includes built-in hardware peripherals such as PWM generators, watchdog timers, and power-on reset circuits.

Applications

• Consumer electronics requiring low pin count and mixed-signal capabilities
• Industrial control systems utilizing programmable I/O and communication interfaces
• Embedded applications needing compact form factor solutions

Procurement Notes

Verify the manufacturer part number CY8C21534-24PVXI against official Infineon or Cypress documentation to ensure authenticity. Confirm that the 28-SSOP package matches your PCB footprint requirements. Check for specific suffix variations if tape-and-reel packaging is required instead of tube. Ensure compliance with RoHS standards if mandated by your project specifications.

Selection Notes

Select this component when an 8-bit MCU with integrated analog-digital programmability is required. The 24MHz clock speed and 8KB Flash are suitable for moderate processing tasks. Consider the 28-pin SSOP package constraints and 24 available I/O lines for interface planning. Verify that the 2.4V to 5.25V supply range aligns with your system power design.

Part Context

This device belongs to the PSoC 1 family, which combines an 8-bit CPU with configurable analog and digital blocks. It targets applications minimizing board space and component count. The CY8C21534 variant specifically offers 8KB Flash and 512 bytes RAM. It is designed for cost-sensitive embedded markets requiring flexible peripheral configuration.

Replacement Considerations

Check for CY8C21534-24PVXIT for tape-and-reel packaging variants. Review CY8C21534-12PVXE for lower clock speed alternatives within the same series. Consult official substitution guides for package or speed differences.
