ATTINY12V-1PI

Overview

The ATTINY12V-1PI is an 8-bit microcontroller based on the AVR RISC architecture, featuring 1K byte of Flash program memory and 64 bytes of In-System Programmable EEPROM. It operates within a voltage range of 1.8 to 5.5 volts with a maximum clock frequency of 1.2 MHz. The device includes 32 general-purpose working registers, one 8-bit Timer/Counter, an analog comparator, and a programmable Watchdog Timer. It supports SPI programming and offers low-power Idle and Power-down modes.

Feature Summary

• High-performance 8-bit RISC architecture executing most instructions in a single clock cycle
• Nonvolatile memory with 1K Flash and 64 bytes ISP EEPROM for data retention
• Integrated peripheral features including pin change interrupts and an analog comparator
• Low-power operation with selectable Idle and Power-down sleep modes

Applications

• Embedded control applications requiring low power consumption
• Systems utilizing In-System Programming via SPI port
• Applications necessitating interrupt-driven wake-up from power-down mode

Procurement Notes

Verify that the specific ordering code matches the required speed grade and package type. Confirm the industrial temperature range suitability for the intended environment. Check current product status as this family may be marked not recommended for new designs. Ensure compatibility with existing development tools and programming protocols.

Selection Notes

Select this component when a low-voltage operation down to 1.8V is required alongside minimal memory requirements. Consider the ATtiny12V variant over other speed grades if the system design prioritizes ultra-low power consumption at lower frequencies. Evaluate the availability of six I/O lines against specific interface needs.
