ATTINY48-12PU

Overview

The ATtiny48-12PU is an 8-bit AVR microcontroller featuring 4KB of In-System Programmable Flash, 64 bytes of EEPROM, and 256 bytes of SRAM. It operates at speeds up to 12MHz within a voltage range of 1.8V to 5.5V. The device includes a 6-channel 10-bit ADC, two timer/counters, SPI, and I2C interfaces. It utilizes a 28-pin PDIP package and supports industrial temperatures from -40°C to +85°C.

Feature Summary

• Advanced RISC architecture with single-cycle execution for high throughput
• In-system programmable non-volatile memory segments
• Integrated analog-to-digital converter and analog comparator
• Multiple power-saving sleep modes including idle and power-down

Applications

• Embedded control systems requiring low power consumption
• Battery-operated devices utilizing extended data retention
• Industrial applications operating within wide temperature ranges

Procurement Notes

Verify the specific speed grade suffix matches the required operational frequency for your voltage conditions. Confirm package integrity upon receipt as the PDIP variant is susceptible to mechanical stress during insertion. Ensure compatibility with existing development tools, as this legacy device may require specific IDE configurations for programming.

Selection Notes

Select this component when 4KB program memory suffices for application logic. Compare against the ATtiny88 if larger memory capacity is needed, as they share identical pinouts and peripheral sets. Consider the 12MHz speed rating relative to the supply voltage to ensure timing requirements are met under all operating conditions.

Part Context

This part belongs to the ATtiny48/88 family, which shares architectural similarities but differs in memory size. The ATtiny48 specifically provides 4KB Flash compared to the 8KB found in the ATtiny88. Both variants utilize the same enhanced RISC core and peripheral configuration, differing primarily in storage capacity.

FAQ

How does the ATtiny48 differ from the ATtiny88?

The primary difference is memory size; the ATtiny48 has 4KB Flash and 256 bytes SRAM, while the ATtiny88 has 8KB Flash and 512 bytes SRAM.

What is the function of the PC6 pin?

PC6 serves as the reset input by default. If the RSTDISBL fuse is programmed, it functions as a general-purpose I/O pin.
