The ATTINY84A-SSFR from Microchip Technology is a low-power 8-bit AVR microcontroller designed for compact embedded control applications. It integrates 8KB of in-system programmable Flash memory, 512 bytes of SRAM and 512 bytes of EEPROM, with a maximum operating frequency of 20MHz.
The device provides up to 12 programmable I/O lines and an 8-channel 10-bit ADC for interfacing with sensors and other analog signals. Integrated peripherals include timers/counters, PWM functions, watchdog timer, brown-out detection/reset, power-on reset and an internal oscillator, helping reduce external component requirements in embedded designs.
The ATTINY84A also includes a Universal Serial Interface (USI) for serial communications and supports in-system programming. Its supply-voltage range is 1.8V to 5.5V, while the maximum clock frequency reaches 20MHz under the appropriate supply conditions specified in the device documentation.
The ATTINY84A-SSFR ordering code is supplied in a 14-lead SOIC package and is specified for an extended operating temperature range of -40°C to +125°C. It is supplied in 3000-piece tape-and-reel packaging, making it suitable for automated surface-mount production. Typical applications include sensor controllers, appliances, industrial controls, portable electronics, LED control and compact embedded systems.
