Design & Procurement Notes

For new designs, the listed Obsolete status should be considered in lifecycle planning. The 100-LFQFP (14x14) package requires surface-mount assembly and a PCB footprint compatible with 100-LQFP. The 1.8V ~ 5.5V supply range should be matched to the board power rails, while the -20°C ~ 85°C (TA) range defines the specified ambient operating condition. Designers should verify that the 88 I/O, FLASH, RAM, EEPROM, internal oscillator, and available serial, LCD, PWM, POR, Voltage Detect, and WDT resources match the system requirements.
