ATTINY24A-CCUR

Overview

The ATTINY24A-CCUR is an 8-bit AVR microcontroller featuring 2KB of In-System Programmable Flash, 128 bytes of EEPROM, and 128 bytes of SRAM. It operates at a maximum clock frequency of 20 MHz with a supply voltage range of 1.8V to 5.5V. The device includes a 10-bit ADC with 8 single-ended channels and programmable gain for differential pairs, two PWM-capable timers, and a Universal Serial Interface. It is housed in a 15-ball UFBGA package (15CC1) and supports industrial temperature ranges.

Feature Summary

• Advanced RISC architecture executing most instructions in a single clock cycle
• Non-volatile memory segments with high endurance specifications
• Integrated analog-to-digital converter with programmable gain stages
• Multiple low-power operating modes including idle and power-down

Applications

• In-system programming via SPI interface
• Touch sensing applications using QTouch Library
• Industrial control systems requiring robust I/O lines
• Battery-powered devices utilizing low power consumption modes

Procurement Notes

Verify the specific speed grade suffix corresponds to the required operational frequency for your voltage conditions. Confirm the 'R' suffix indicates tape and reel packaging if automated assembly is planned. Ensure the UFBGA package dimensions match your PCB footprint requirements. Check RoHS compliance documentation for environmental regulations relevant to your region.

Selection Notes

Select this component when a compact 15-ball UFBGA package is necessary for space-constrained designs. Consider the 20 MHz performance limit relative to the 1.8V to 5.5V operating range. Evaluate the 128-byte SRAM capacity against application stack requirements. Verify that the industrial temperature range meets environmental exposure standards.

Part Context

This part belongs to the ATtiny24A/44A/84A family of low-power CMOS 8-bit microcontrollers based on the AVR enhanced RISC architecture. The family shares core peripherals such as timers, ADCs, and interrupt systems, differing primarily in memory sizes and package options. The CCUR suffix specifically denotes the UFBGA package variant with tape and reel delivery.

Replacement Considerations

ATtiny24A-CCU serves as the non-reel equivalent in the same package.
