ATTINY24A-CCU

Overview

The ATTINY24A-CCU is an 8-bit AVR microcontroller featuring a RISC core with 2KB of in-system programmable Flash memory and 128 bytes of EEPROM. It operates at a maximum clock frequency of 20 MHz across a supply voltage range of 1.8V to 5.5V. The device includes 12 programmable I/O lines, two PWM channels, a 10-bit ADC, and a Universal Serial Interface (USI). It is housed in a 16-pin QFN package.

Feature Summary

• Advanced RISC architecture enabling most instructions to execute in a single clock cycle
• Non-volatile memory segments with high endurance for Flash and EEPROM data retention
• Integrated peripheral features including timers, ADC, and analog comparator
• Low power consumption with multiple idle and power-down modes

Applications

• Battery-powered embedded systems requiring low voltage operation
• Industrial control applications utilizing the USI interface
• Consumer electronics employing PWM for motor or LED control
• Sensor interfaces leveraging the internal 10-bit ADC

Procurement Notes

Verify the specific suffix 'CCU' against official Microchip documentation to confirm the exact package type and tape-and-reel configuration. Ensure the component matches the required operating temperature range and voltage specifications for your design. Cross-reference the datasheet revision to confirm pinout compatibility before integration.

Selection Notes

Select this component when a compact 8-bit MCU with integrated Flash and EEPROM is required. It is suitable for designs needing a balance of processing speed and low power consumption. Consider the 16-pin QFN package constraints for PCB layout. Verify that the 20 MHz speed grade meets the timing requirements of the target application.

Part Context

This part belongs to the ATtiny family of 8-bit AVR microcontrollers produced by Microchip Technology (formerly Atmel). The family is known for high performance and low power consumption. The ATTINY24A variant specifically offers 2KB of Flash memory, distinguishing it from other members with different memory capacities within the same series.

Replacement Considerations

Compatible substitutes include ATTINY24A-MFR and ATTINY24A-SSNR. Verify package compatibility and electrical specifications before substitution.
