CY8C21645-24PVXA

Overview

The CY8C21645-24PVXA is an 8-bit microcontroller from the PSoC 1 family, manufactured by Infineon Technologies. It features an M8C core with 16 kB of Flash program memory and 1024 bytes of SRAM data RAM. The device operates at a maximum clock frequency of 24 MHz and supports a supply voltage range of 2.4 V to 5.25 V. It includes a 10-bit ADC with 28 channels and provides 32 I/O pins in a 44-pin SSOP package. Operating temperatures range from -40°C to +85°C.

Feature Summary

• Integrates configurable analog and digital peripherals within a mixed-signal system-on-chip architecture.
• Supports multiple communication interfaces including I2C, SPI, and UART for versatile connectivity.
• Features a high-resolution 10-bit Analog-to-Digital Converter with extensive channel availability.

Applications

• Consumer electronics requiring low pin count and mixed-signal processing
• Industrial control systems utilizing programmable logic and analog inputs
• Embedded sensor nodes and IoT end-point devices

Procurement Notes

Verify the specific suffix 'A' against official Infineon documentation to confirm package type and temperature grade accuracy. Ensure compatibility with existing design constraints regarding the 44-pin SSOP footprint and 2.4V to 5.25V power supply requirements before finalizing procurement.

Selection Notes

Select this component when a design requires a balance of moderate Flash capacity and extensive analog input channels. The PSoC 1 architecture allows for hardware-level customization of peripherals, reducing external component count compared to standard MCU solutions.

Part Context

This part belongs to the CY8C21x34 series of PSoC 1 devices, which are designed to minimize board space and development time. The series combines an 8-bit processor with reconfigurable analog blocks, targeting applications that need flexible signal conditioning alongside digital control capabilities.

Replacement Considerations

Check for CY8C21645 variants with different suffixes (e.g., PVXI) if alternative packaging or commercial/industrial temperature grades are required. Verify pinout compatibility before substituting with other members of the CY8C21xxx family.
