ATTINY12L-4PC

Overview

The ATTINY12L-4PC 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 2.7V to 5.5V and supports clock frequencies up to 4MHz. It includes 32 general-purpose working registers, six I/O lines, an 8-bit Timer/Counter, and an analog comparator. The component is housed in an 8-lead Plastic Dual Inline Package (PDIP) and is designated for industrial temperature operation.

Feature Summary

• Utilizes high-performance 8-bit RISC architecture with single-clock-cycle instruction execution
• Includes nonvolatile Flash and EEPROM memory with programming lock security
• Features low-power Idle and Power-down modes with pin change wake-up capability
• Integrates an internal calibrated RC oscillator and programmable Watchdog Timer

Applications

• Embedded control applications requiring low power consumption
• Battery-powered devices utilizing power-saving sleep modes
• Simple sensor interfaces using analog comparator and timer functions
• Cost-effective solutions for basic logic control tasks

Procurement Notes

Verify that the specific part number matches the required speed grade and package type. Confirm the operating temperature range aligns with industrial specifications. Check for current availability status as this series may be marked as not recommended for new design. Ensure compatibility with existing development tools and programming interfaces before procurement.

Selection Notes

Select this component when a low-cost 8-bit MCU with minimal I/O requirements is needed. Consider the ATTINY12L-4PC for designs prioritizing low active and standby power consumption. Evaluate the available Flash and EEPROM sizes against application memory needs. Verify that the 4MHz maximum frequency meets processing speed requirements.

Part Context

This device belongs to the ATtiny11/12 family of microcontrollers. It shares architectural similarities with the ATtiny11 but adds EEPROM and SPI programming capabilities. The 'L' suffix indicates a lower voltage operating range compared to standard variants. The '4' denotes the maximum clock frequency speed grade. The 'PC' suffix specifies the PDIP package and industrial temperature rating.

Replacement Considerations

Public confirmed substitute part numbers include ATTINY12L-4PI and ATTINY12L-4PU.
