The ATTINY1616-SN is an 8-bit, 20MHz, SOIC 85C microcontroller manufactured by Microchip. It has a low-power real-time counter, six timer/counters, up to 60LCD driver gray codes, up to 16KB of flash program memory, up to 1KB of EEPROM data memory, and 8K-byte of RAM with external data memory expansion options. It also features full-scale and programmable analog-to-digital converter, up to 28-channel general purpose I/O, up to 16 event-based analog comparators, up to 14-channel SPI, USART and TWI. Furthermore, it has a two-phase pulse-width modulation controller, XMEGA Event System, on-chip debug, and clock prescaler to divide the system clock. The ATTINY1616-SN is packaged in a SOIC 85C green package.
