CY8C27643-24PVXI

Overview

The CY8C27643-24PVXI is an 8-bit microcontroller within the PSoC 1 family, utilizing the M8C core and CMOS technology. It features 16 kB of Flash program memory and 256 B of SRAM data memory. The device operates with a supply voltage range of 3 V to 5.25 V and supports a maximum clock frequency of 24 MHz. It includes a 14-bit ADC with 12 channels, two timers/counters, and interfaces such as GPIO, I2C, SPI, and UART. Housed in a 48-pin SSOP package, it functions within a temperature range of -40°C to +85°C.

Feature Summary

• Integrates configurable analog and digital peripherals on a single chip for system-level flexibility.
• Combines an 8-bit microcontroller with embedded Flash, EEPROM, and SRAM memories.
• Supports multiple communication protocols including I2C, SPI, and UART.

Applications

• Wireless intrabody communication sensor nodes
• Signal synthesis using digital-to-analog conversion
• Consumer and industrial equipment control

Procurement Notes

Verify the specific suffix PVXI against official Infineon documentation to confirm pinout and package dimensions. Ensure compatibility with required operating temperatures and voltage levels. Confirm RoHS compliance status through current datasheets. Check for moisture sensitivity classification prior to surface mount assembly processes.

Selection Notes

Select this component when an 8-bit architecture with mixed-signal capabilities is required. The 16 kB Flash and 256 B RAM suit moderate complexity applications. The 48-pin SSOP package offers a balance of I/O count and board space. Consider the 24 MHz speed limit for timing-critical tasks.

Part Context

This part belongs to the Infineon (formerly Cypress) PSoC 1 series, designed as a programmable system-on-chip solution. It targets markets requiring design flexibility and reduced component counts by integrating analog and digital blocks.

Replacement Considerations

Consult official cross-reference guides for verified substitutes. Generic MCU replacements may lack the specific PSoC configurability.
