ATTINY84A-CCU

Overview

The ATTINY84A-CCU is an 8-bit AVR microcontroller featuring 8KB of in-system programmable Flash memory, 512 bytes of EEPROM, and 512 bytes of SRAM. It operates at clock frequencies up to 20MHz with a supply voltage range of 1.8V to 5.5V. The device includes eight 10-bit ADC channels, a universal serial interface (USI), and multiple timer/counters. It is housed in a 32-VFBGA package.

Feature Summary

• High-performance 8-bit AVR architecture with single-cycle instruction execution
• Integrated non-volatile memory for program storage and data retention
• Built-in analog-to-digital conversion with multiple input channels
• Supports low-power operation modes including idle and power-down

Applications

• Battery-powered consumer electronics
• Industrial control systems
• Smart home devices
• Sensor interfaces

Procurement Notes

Verify the specific suffix 'CCU' corresponds to the 32-VFBGA package and lead-free status as per Microchip documentation. Confirm RoHS compliance and operating temperature range (-40°C to +85°C) against project requirements. Ensure ESD handling procedures are followed during assembly due to the fine-pitch ball grid array packaging.

Selection Notes

Select this component when 8KB of Flash is required alongside 512 bytes of EEPROM and SRAM. The 32-VFBGA package suits applications needing high pin density in a small footprint. Consider the 20MHz maximum speed and 1.8V minimum supply voltage for low-power designs. Verify peripheral needs such as USI and ADC channel count match the application design.

Part Context

This part belongs to the ATtiny family of 8-bit AVR microcontrollers. It shares architectural similarities with the ATtiny24A and ATtiny44A but offers increased memory capacity. The 'A' suffix typically denotes enhanced features or updated manufacturing processes compared to earlier variants. It is designed for cost-sensitive applications requiring efficient code execution.

Replacement Considerations

Direct substitutes include other members of the ATtiny44/84 series with compatible pinouts and memory sizes. Verify package compatibility when replacing with similar parts from the same manufacturer. Cross-reference datasheets for any differences in peripheral configurations or electrical specifications before implementation.
