The CY8CPLC20-28PVXI is a programmable system-on-chip (PSoC) device from Infineon Technologies, designed for power line communication applications. It integrates an M8C CPU core with 32 kByte of Flash memory and 2408 bytes of SRAM. The component operates at a maximum frequency of 24 MHz and supports a data rate of up to 2400 bit/s. It features 24 general-purpose I/O pins and includes programmable interfaces such as I2C, SPI, and UART. The device functions within a voltage range of 4.75 V to 5.25 V and operates in temperatures from -40 °C to +85 °C. It is housed in a 28-lead SSOP package.
Verify the specific ordering suffix against official Infineon documentation to ensure correct package type and temperature grade. Confirm RoHS compliance status through current datasheets or product qualification reports. Check for moisture sensitivity level requirements during storage and handling procedures prior to assembly.
Select this component when a combined MCU and PLC transceiver solution is required on a single chip. Ensure the application utilizes the 24 I/O pins effectively given the limited pin count. Verify that the 2408 byte SRAM capacity meets the runtime data processing needs of the specific firmware implementation.
This part belongs to the CY8CPLC20 series of PSoC devices. It combines standard microcontroller functionality with specialized power line communication hardware. The series is designed to simplify integration of PLC capabilities into existing embedded systems without requiring external discrete components.
Consult official Infineon cross-reference guides for verified substitutes. Direct replacements must match the 28-lead SSOP package and maintain compatible electrical specifications.
