Procurement Notes
Verify the specific suffix M445 corresponds to the 64-TQFP(14x14) package and commercial temperature range (-40°C to +85°C). Confirm RoHS compliance status and moisture sensitivity level (MSL 3) requirements for your assembly process. Ensure the ordering part number matches the exact memory configuration and pinout defined in the official datasheet to avoid compatibility issues with existing PCB layouts.
Selection Notes
Select this component when a balance of processing speed and low power consumption is required for cost-sensitive embedded designs. The PSoC 4200M architecture offers flexibility through its programmable interconnects. Consider this MCU for projects needing moderate I/O counts and basic analog signal acquisition without external components. Evaluate the 48 MHz performance against application latency requirements.
Part Context
This part belongs to the PSoC 4200M family, designed for high-performance, low-power applications. It combines a standard ARM Cortex-M0 processor with Cypress/Infineon's proprietary programmable analog and digital block technology. This integration reduces system component count and board space compared to discrete solutions.
Replacement Considerations
Check for CY8C4246AXI-M445 if a different package or variant is needed. Verify cross-compatibility with other PSoC 4200M members sharing the same core and memory size but differing in package or peripheral availability.
