ATTINY12V-1SI

Overview

The ATTINY12V-1SI is an 8-bit microcontroller based on the AVR RISC architecture, featuring a 1K byte Flash program memory and 64 bytes of in-system programmable EEPROM. It operates within a voltage range of 1.8V to 5.5V 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.

Procurement Notes

Verify component authenticity through authorized Microchip Technology distributors or direct channels. Confirm package type matches the SOIC-8 specification required for your design. Check current lifecycle status as this series may be marked not recommended for new designs. Ensure environmental compliance documentation aligns with project requirements.

Selection Notes

Select this component when a low-voltage 1.8V operating range is necessary alongside minimal peripheral requirements. Consider the 1.2 MHz speed grade if processing demands are modest. Evaluate the trade-off between the integrated EEPROM and the simpler ATtiny11 variant if data retention is critical. Verify that the SOIC-8 package fits the available PCB footprint constraints.

Part Context
