Microchip Technology's AVR® ATtiny, Functional Safety (FuSa) series microcontroller, part number ATTINY45-20SI, features an 8-bit AVR core operating at up to 20MHz. This device offers 4KB of FLASH program memory and 256 bytes each of EEPROM and SRAM. Peripheral capabilities include a Universal Serial Interface (USI) for communication, four 10-bit Analog-to-Digital converters, and essential safety features such as Brown-out Detect/Reset, Power-On Reset (POR), Pulse Width Modulation (PWM), and Watchdog Timer (WDT). The ATTINY45-20SI is packaged in an 8-SOIC (0.209" width) surface-mount case, designed for operation within a 2.7V to 5.5V supply range and an ambient temperature range of -40°C to 85°C. Its internal oscillator simplifies design. This component finds application in various industrial and consumer electronics sectors requiring robust control and safety features.
