ATTINY24-20PU

Overview

The ATTINY24-20PU is an 8-bit AVR microcontroller featuring a 14-pin PDIP package. It includes 2 KB of in-system programmable Flash memory, 128 bytes of EEPROM, and 128 bytes of SRAM. The device supports a maximum clock frequency of 20 MHz at operating voltages between 4.5 V and 5.5 V. It provides twelve programmable I/O lines and integrates an 8-channel 10-bit ADC with programmable gain.

Feature Summary

• Advanced RISC architecture executing most instructions in a single clock cycle
• In-system programmable non-volatile memory for program and data storage
• Integrated analog-to-digital converter with differential channel pairs and programmable gain
• On-chip debug system supporting serial programming via SPI interface

Applications

• Embedded control systems requiring low power consumption
• Sensor interfacing utilizing the integrated ADC capabilities
• Industrial applications within the specified temperature range

Procurement Notes

Verify the specific ordering code matches the required speed grade and voltage range. Confirm the package type corresponds to the design requirements. Check for any applicable RoHS compliance documentation. Ensure the component revision aligns with project specifications regarding errata conditions.

Selection Notes

Select this variant when a through-hole 14-pin package is necessary for the PCB layout. Consider the 20 MHz speed grade if operation occurs strictly above 4.5 V. Evaluate the memory size against application requirements before choosing higher capacity models in the series.
