CY8C4245PVI-482

Overview

The CY8C4245PVI-482 is an ARM Cortex-M0 microcontroller from the Infineon PSoC 4200 series, housed in a 28-pin SSOP package. It features 32 kB of Flash program memory and 4 kB of SRAM data RAM. The device operates with a maximum clock frequency of 48 MHz and supports a supply voltage range of 1.71 V to 5.5 V. It includes one 12-bit SAR ADC, two comparators, four timer/counters, and offers 24 general-purpose I/O pins. Communication interfaces include I2C, SPI, and UART.

Feature Summary

• Integrates an ARM Cortex-M0 processor core for efficient code execution within a programmable system-on-chip architecture.
• Provides flexible analog capabilities through a single-channel 12-bit successive approximation register (SAR) analog-to-digital converter.
• Includes dedicated hardware peripherals such as two digital comparators and multiple timer/counter/pulse width modulation blocks.
• Supports standard serial communication protocols via configurable serial communication blocks for interfacing with external devices.

Applications

• Battery-powered portable devices requiring low power consumption and small form factor
• Industrial control systems utilizing serial communication interfaces
• Consumer electronics incorporating sensor data acquisition via ADC

Procurement Notes

Verify the specific suffix '482' confirms the 48 MHz speed grade and 28-SSOP package variant during sourcing. Confirm RoHS compliance status and moisture sensitivity level requirements against project specifications. Ensure the ordering quantity aligns with tube packaging constraints if applicable. Cross-reference the manufacturer part number with official Infineon documentation to avoid confusion with similar PSoC 4 variants.

Selection Notes

Select this component when a balance of moderate processing speed and integrated analog peripherals is required. The wide supply voltage range facilitates direct interfacing with various logic levels without additional level shifters. Consider the limited DMA channels and absence of USB interface when designing complex data throughput applications. Evaluate pin count adequacy for the target application's I/O requirements before finalizing the design.

Part Context

This microcontroller belongs to the PSoC 4200 family, which combines a standard ARM Cortex-M0 core with Cypress/Infineon's programmable analog and digital block technology. This architecture allows customization of peripheral functions to reduce external component count. The CY8C4245PVI-482 represents a specific configuration within this family, optimized for cost-sensitive applications needing reliable MCU performance.

Replacement Considerations

Consult official Infineon cross-reference tools for verified substitutes. Variants within the CY8C4245 series may offer different memory sizes or package options. Ensure any replacement maintains compatibility with the 28-SSOP footprint and electrical characteristics if board space is constrained.
