ATTINY12-8PU

Overview

The ATtiny12-8PU is an 8-bit microcontroller based on the AVR RISC architecture, manufactured by Microchip Technology. It features 1K byte of Flash program memory and 64 bytes of In-System Programmable EEPROM data memory. The device operates within a voltage range of 4.0V to 5.5V with a maximum clock frequency of 8 MHz. It includes 32 general-purpose working registers, six I/O lines, an 8-bit Timer/Counter, an analog comparator, and a programmable watchdog timer. The component is housed in an 8-pin PDIP package.

Feature Summary

• High-performance 8-bit RISC architecture with single-clock-cycle execution
• Nonvolatile memory with 1K Flash and 64B EEPROM for data retention
• Integrated peripherals including analog comparator and watchdog timer
• Low-power operation with idle and power-down modes

Applications

• Embedded control applications requiring low power consumption
• Systems utilizing internal calibrated RC oscillator
• Applications needing in-system programming via SPI port

Procurement Notes

Verify the specific ordering suffix 'PU' corresponds to the 8-lead Plastic Dual Inline Package (PDIP) as defined in the official ordering information tables. Confirm that the speed grade '8' indicates the 0-8 MHz operational range suitable for the intended application timing requirements. Ensure compliance with the specified 4.0V to 5.5V operating voltage constraints during system design validation.

Selection Notes

Select this component when a low-cost, 8-bit AVR microcontroller with EEPROM is required for simple embedded tasks. It is suitable for designs operating between 4.0V and 5.5V where up to 8 MHz processing speed is sufficient. Consider the 8-pin PDIP package if through-hole mounting is necessary for the PCB layout. Evaluate power consumption needs against the available idle and power-down modes.

Part Context

This part belongs to the ATtiny11/12 family of 8-bit microcontrollers. It shares the core AVR architecture with variants like ATtiny11 and other speed grades such as ATtiny12L-4. The family is characterized by high-density nonvolatile memory technology and a rich instruction set optimized for code efficiency and throughput relative to power consumption.
