ATTINY12-8SC

Overview

The ATTINY12-8SC is an 8-bit AVR microcontroller featuring a 1K byte Flash program memory and 64 bytes of EEPROM. It operates within a voltage range of 4.0 to 5.5V with a maximum clock frequency of 8 MHz. The device utilizes the high-performance, low-power AVR RISC architecture, executing most instructions in a single clock cycle. It includes 32 general-purpose working registers, an 8-bit Timer/Counter, an on-chip Analog Comparator, and a Programmable Watchdog Timer. The component is housed in an 8-lead SOIC package.

Feature Summary

• High-performance 8-bit RISC architecture achieving up to 8 MIPS throughput at 8 MHz
• Nonvolatile memory including 1K byte Flash and 64 bytes In-System Programmable EEPROM
• Integrated peripherals such as an 8-bit Timer/Counter, Analog Comparator, and Programmable Watchdog Timer
• Low-power operation with Idle and Power-down modes

Applications

• Embedded control applications requiring compact form factor
• Battery-powered systems utilizing low-power sleep modes
• Simple sensor interfaces using analog comparator and pin change interrupts

Procurement Notes

Verify the specific suffix 'SC' corresponds to the commercial temperature range (0°C to 70°C) and SOIC-8 package configuration. Confirm that the source documentation identifies this part as not recommended for new designs. Ensure compatibility with existing SPI programming interfaces if used for firmware updates.

Selection Notes

Select this component when a cost-effective 8-bit solution with minimal I/O is required. It is suitable for applications where code size fits within 1K bytes and data retention needs are met by 64 bytes of EEPROM. Consider the 4.0V minimum operating voltage constraint for power supply design.

Part Context

This device belongs to the ATtiny11/12 family manufactured by Microchip Technology (formerly Atmel). It shares architectural similarities with the ATtiny11 but adds EEPROM capabilities. The family is characterized by its small physical footprint and efficient instruction set designed for resource-constrained embedded environments.

Replacement Considerations

Public confirmed substitute part numbers: None.
