ATTINY84A-CCU

Overview

The ATTINY84A-CCU is an 8-bit microcontroller based on the AVR enhanced RISC architecture, manufactured by Microchip Technology. It features 8K bytes of in-system programmable Flash memory, 512 bytes of EEPROM, and 512 bytes of SRAM. The device operates at a maximum clock frequency of 20 MHz with a supply voltage range of 1.8V to 5.5V. It includes twelve general-purpose I/O lines, an 8-channel 10-bit ADC with programmable gain, two timer/counters with PWM channels, and a universal serial interface. The component is housed in a 15-ball UFBGA package (15CC1) and supports industrial temperature ranges.

Feature Summary

• Executes powerful instructions in a single clock cycle for high throughput efficiency.
• Provides non-volatile memory segments with high endurance for Flash and EEPROM data retention.
• Integrates peripheral features including an analog comparator, watchdog timer, and pin change interrupts.
• Supports low power consumption through multiple software-selectable sleep modes.

Applications

• In-system programming via SPI port
• On-chip debug system support
• Touch sensing interfaces using QTouch Library

Procurement Notes

Verify the specific ordering code against the manufacturer's official documentation to ensure correct package type and speed grade. Confirm that the component meets RoHS compliance requirements as specified in the datasheet. Check for any recent product change notices regarding marking or manufacturing site updates before finalizing procurement specifications.

Selection Notes

Select this model when 8K Flash memory and a 15-ball UFBGA package are required for space-constrained designs. Ensure the application environment falls within the specified industrial temperature range and voltage limits. Consider the availability of development tools and libraries if touch sensing capabilities are needed for the project.

Part Context

This component belongs to the ATtiny24A/44A/84A family of low-power CMOS 8-bit microcontrollers. These devices are designed for applications requiring small size, fast processing, and energy efficiency. The family shares a common instruction set and peripheral structure, differing primarily in memory sizes and package options.

Replacement Considerations

Compatible substitutes include other variants within the ATtiny24A/44A/84A series, such as ATtiny84A-MU or ATtiny84A-MMH, provided the package footprint and pinout compatibility are verified. Cross-referencing the specific speed grade and temperature rating is essential for direct replacement.
