ATTINY4313-PU

Overview

The ATtiny4313-PU is an 8-bit AVR microcontroller in a 20-pin PDIP package. It features 4K bytes of In-System Programmable Flash, 256 bytes of EEPROM, and 256 bytes of SRAM. The device operates at speeds up to 20 MHz with supply voltages between 1.8V and 5.5V. It includes 18 programmable I/O lines, two Timer/Counters, four PWM channels, a USART, USI, and an analog comparator.

Feature Summary

• Advanced RISC architecture achieving up to 20 MIPS throughput at 20 MHz
• In-system self-programmable Flash memory with high endurance
• On-chip debugging via debugWIRE interface
• Multiple low-power operating modes including Idle and Power-down

Applications

• Embedded control systems requiring non-volatile data storage
• Battery-powered applications utilizing low power consumption modes
• Industrial environments requiring industrial temperature range operation
• General-purpose digital logic interfacing via 18 I/O lines

Procurement Notes

Verify the ordering code matches the specific speed grade and package variant required for your design. Confirm that the industrial temperature range (-40°C to +85°C) aligns with your operational environment specifications. Ensure compatibility with existing programming interfaces such as SPI or debugWIRE before finalizing procurement.

Selection Notes

Select this component when 4K Flash and 256 bytes of RAM are necessary compared to the smaller ATtiny2313A variant. The PDIP package is suitable for through-hole prototyping or manufacturing. Consider the 20 MHz speed grade if higher processing throughput is needed within the 1.8V to 5.5V voltage range.

Part Context

This part belongs to the ATtiny family of 8-bit microcontrollers based on the AVR enhanced RISC architecture. It shares pinouts and peripheral sets with the ATtiny2313A but offers double the memory capacity. The -PU suffix specifically denotes the 20-lead Plastic Dual Inline Package format.

Replacement Considerations

ATtiny2313A-PU serves as a lower-memory alternative within the same package. Other variants like ATtiny4313-SU offer the same core functionality in a surface-mount SOIC package.
