The ATTINY84A-MMHR is a surface-mount, high-performance microcontroller IC (integrated circuit) developed by Microchip Technology. It belongs to the ATTINY series of MCUs, which are low-power, high-performance chips commonly used in various embedded systems and IoT (Internet of Things) applications.
One of the key features of the ATTINY84A-MMHR is its small package size and low power consumption. It comes in a compact, 14-pin package (4mm x 4mm) and operates at low voltages, making it suitable for space-constrained designs and battery-powered devices.
The MCU is based on the AVR microcontroller architecture, which provides high-performance execution and low power consumption. It has a powerful CPU with 8-bit RISC (Reduced Instruction Set Computing) architecture, capable of executing instructions at high speeds.
The ATTINY84A-MMHR offers 8KB of flash memory, which allows storing program code and data. It also provides 512 Bytes of SRAM (Static Random Access Memory) for temporary storage during program execution. The MCU supports in-system programming, enabling users to update the firmware directly through the IC's pins, enhancing flexibility during development.
Additionally, the ATTINY84A-MMHR has a rich set of peripherals, including analog-to-digital converters (ADCs), pulse-width modulation (PWM) channels, and timers/counters
