ATTINY84A-CCUR

Overview

The ATTINY84A-CCUR is an 8-bit microcontroller based on the AVR enhanced RISC architecture, manufactured by Microchip Technology. It features 8 Kbytes 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 1.8 V to 5.5 V. It includes 12 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 8-bit Timer/Counter, a 16-bit Timer/Counter, and a 10-bit ADC with differential channel pairs.
• Supports low power consumption through multiple software-selectable sleep modes.

Applications

• In-system programming via SPI port
• On-chip debug system using debugWIRE
• Touch sensitive interfaces utilizing QTouch Library

Procurement Notes

Verify the specific ordering code ATTINY84A-CCUR against official Microchip documentation to confirm the 15CC1 UFBGA package type and matte tin lead finish. Ensure compatibility with the required industrial temperature range and speed grade specifications before procurement. Cross-reference datasheet revision 8183FS for accurate electrical characteristics and pin configurations.

Selection Notes

Select this component when an 8-bit AVR core with 8 KB Flash and UFBGA packaging is required. Consider the 20 MHz speed grade and 1.8 V to 5.5 V operating voltage range. Evaluate the need for 12 I/O lines and the specific ADC resolution. Confirm that the 15-ball array package fits the board layout constraints compared to SOIC or QFN alternatives.

Part Context

This part belongs to the ATtiny24A/44A/84A family of low-power CMOS 8-bit microcontrollers. It shares the same core architecture and peripheral set as the ATtiny24A and ATtiny44A, differing primarily in memory capacity. The family utilizes Atmel's high density non-volatile memory technology and is supported by comprehensive development tools including C compilers and simulators.

FAQ

What is the pin configuration for the UFBGA package?

The 15CC1 package is a 15-ball (4 x 4 Array) with a 0.65 mm pitch and dimensions of 3.0 x 3.0 x 0.6 mm.

How does the device handle power-down mode?

In Power-down mode, registers retain their contents while all chip functions are disabled until the next interrupt or hardware reset occurs.

What is the data retention specification for the internal memory?

The data retention is specified as 20 years at 85°C or 100 years at 25°C.
