Microcontrollers Procurement Notes

Verify the specific suffix #50 indicates tape and reel packaging when ordering. Confirm the 64-LQFP package dimensions match your PCB footprint design. Ensure the -40°C to 105°C automotive-grade temperature rating aligns with your environmental requirements. Check for RoHS3 compliance status if required by your manufacturing standards. Validate pinout compatibility against your schematic before finalizing procurement.

Microcontrollers Selection Notes

Select this model when 32KB of Flash and 4KB of EEPROM are sufficient for application logic and data storage. Choose the 64-LQFP package if 48 I/O pins are required within a compact surface-mount form factor. Opt for this part over smaller variants if LINbus support and DMA functionality are necessary. Consider the 1.6V to 5.5V operating range for flexible power supply designs. Verify that the 32MHz clock speed meets your real-time processing constraints.

Microcontrollers Part Context

This component belongs to the RL78/G13 family, designed for automotive and industrial markets. It shares the core architecture with other G13 variants but differs in memory size and package options.
