ATTINY48-PU

Overview

The ATTINY48-PU is an 8-bit AVR microcontroller featuring a picoPower architecture. It integrates 4KB of in-system programmable Flash memory, 256 bytes of SRAM, and 64 bytes of EEPROM. The device operates at clock speeds up to 12MHz with a supply voltage range of 1.8V to 5.5V. It includes six 10-bit analog-to-digital converters, I2C and SPI interfaces, and multiple peripherals such as watchdog timers and power-on reset circuits. The component is housed in a 28-pin PDIP package.

Feature Summary

• Integrates picoPower technology for ultra-low power consumption in active and standby modes.
• Features an enhanced RISC core delivering nearly 1 MIPS per MHz throughput.
• Includes flexible timer/counter modules and pulse width modulation capabilities.
• Supports in-system programming via standard serial programming protocols.

Applications

• Portable battery-powered consumer devices
• Remote control systems
• Small appliance controllers
• Low-power sensor nodes

Procurement Notes

Verify the specific suffix 'PU' confirms the 28-pin PDIP package type. Confirm the manufacturer designation, as Atmel was acquired by Microchip Technology; official documentation may reference Microchip. Check current production status, as legacy AVR devices may have end-of-life notices or be marked as not recommended for new designs. Ensure compatibility with existing development toolchains for older AVR families.

Selection Notes

Select this component when a robust 8-bit solution with moderate memory is required for cost-sensitive applications. The 28-pin DIP package facilitates prototyping on breadboards and through-hole PCB layouts. Consider the 1.8V minimum operating voltage for battery-driven projects. Evaluate if the integrated ADC channels and communication interfaces meet system requirements without external components.

Part Context

This part belongs to the ATtiny family of microcontrollers, specifically the tinyAVR series known for miniaturization and low power. The ATTINY48 shares architectural similarities with the ATtiny88 but offers reduced program memory capacity. It utilizes the standard AVR instruction set, ensuring code compatibility with other devices in the same family. The device represents a balance between processing capability and power efficiency for embedded control tasks.
