Overview

The ATTINY84A-SSFR is an 8-bit AVR microcontroller from Microchip Technology, featuring an advanced RISC architecture and running at up to 20MHz. It includes 8KB of Flash program memory, 512 bytes of SRAM, and 512 bytes of EEPROM. This microcontroller is designed for applications requiring a compact, low-power solution with a versatile set of peripherals.

Why Choose This Part

Engineers choose the ATTINY84A-SSFR for its balance of performance and efficiency in a small footprint. Its 8-bit AVR core, operating at up to 20MHz, offers sufficient processing power for many embedded tasks, while robust power management features enable extremely low sleep currents. The device also provides a rich set of non-volatile memory options, including 8KB Flash and 512 bytes of EEPROM, along with comprehensive debugging and programming features.

Applications

Compact Embedded Systems
Its small 14-SOIC package and integrated peripherals make it suitable for space-constrained designs where a full-featured microcontroller is not required.
Sensor Interfaces
The ATTINY84A can efficiently read and process data from various sensors due to its integrated ADC and support for pin change interrupts.
Low-Power Applications
With multiple low-power modes including Idle, ADC Noise Reduction, Power-down, and Standby, it can achieve sleep currents as low as 0.1uA, extending battery life in portable devices.
Peripheral Control
It offers multiple general-purpose I/O pins, internal and external interrupt sources, and an SPI port for interfacing with other ICs or modules.
DIY and Hobbyist Projects
Due to its simplicity, low cost, and robust AVR architecture, it is a popular choice for prototyping and educational projects.
