Overview
The ATTINY12L-4PU is an 8-bit AVR microcontroller featuring 1KB of in-system programmable Flash memory and 64 bytes of EEPROM. It operates at a maximum frequency of 4MHz with a supply voltage range of 2.7V to 5.5V. The device includes 6 general-purpose I/O lines, an internal oscillator, and peripherals such as a Watchdog Timer and Power-on Reset. It is housed in a 14-pin PDIP package and supports industrial temperature ranges.
Feature Summary
- AVR RISC architecture for efficient code execution
- Non-volatile Flash and EEPROM memory for data retention
- Integrated analog comparator and timer/counter
- Low-power operation with idle and power-down modes
Applications
- Battery-powered sensor nodes
- Simple control loops in consumer electronics
- Low-pin-count interface management
- Basic signal monitoring systems
Procurement Notes
Verify the specific suffix '4PU' against official Microchip documentation to confirm the 4MHz speed grade and PDIP-14 package variant. Ensure compatibility with existing PCB footprints and programming interfaces. Check current availability status as older ATtiny variants may have limited stock or end-of-life implications.
Selection Notes
Select this component when minimal I/O count and low cost are prioritized over processing speed. It suits applications requiring basic logic control without complex communication protocols. Compare against ATTINY12L-4SUR if surface-mount assembly is required instead of through-hole mounting.
Part Context
This part belongs to the ATtiny12 family, designed for resource-constrained embedded applications. It shares core architectural features with other ATtiny devices but offers reduced pin counts and memory sizes. The 'L' suffix typically denotes low-voltage or low-power optimization within the series.
Replacement Considerations
ATTINY12L-4SUR serves as a direct surface-mount equivalent. Verify pinout compatibility before substitution. Other ATtiny12 variants may require firmware adjustments due to differing peripheral configurations.
