Built-in brown-out detection, POR, and a watchdog timer reduce the external supervisor IC count. The internal oscillator means you can bring up a basic design without an external crystal, though the clock accuracy may limit high-precision timing applications. It's ROHS3 compliant, so no exemption paperwork for EU markets.","metaTitle":"Microchip AVR128DB28T-I/SS 8-bit MCU, 128KB Flash, 24MHz","metaDescription":"Microchip AVR128DB28T-I/SS 8-bit AVR MCU with 128KB Flash, 16K x 8 RAM, 24MHz, 23 I/O, 12-bit ADC, 10-bit DAC, -40°C to 85°C, 28-SSOP.
