ATTINY20-CCU

Overview

The ATTINY20-CCU is an 8-bit AVR microcontroller featuring 2 KB of in-system programmable Flash memory and 128 bytes of SRAM. It operates with a maximum clock frequency of 12 MHz and includes a 10-bit ADC. The device supports 12 I/O lines and functions within a supply voltage range of 1.8 V to 5.5 V. It is housed in a 15-UFBGA package and is rated for industrial temperature operation.

Feature Summary

• AVR RISC core architecture providing efficient single-cycle instruction execution
• Integrated 10-bit analog-to-digital converter for signal processing
• In-system programmable non-volatile Flash memory for code storage
• Supports standard communication interfaces including SPI and I2C

Applications

• Battery-powered embedded systems requiring low power consumption
• Industrial control modules operating in harsh environments
• Sensor interface circuits utilizing the onboard ADC
• General-purpose logic control in compact surface-mount designs

Procurement Notes

Verify component status as this specific part number may be marked as Not Recommended for New Designs (NRND). Confirm availability through authorized Microchip Technology distributors. Ensure the 15-UFBGA package footprint matches the design layout. Check for alternative recommended replacements if long-term supply stability is required for new production runs.

Selection Notes

Select this component when a compact 8-bit AVR solution with integrated ADC is needed. The 12 MHz speed grade suits applications not requiring higher frequencies. Consider the 1.8 V minimum supply voltage for compatibility with low-power logic levels. Evaluate the 12 I/O count against system pin requirements before finalizing the selection.
