ATTINY12L-4PI

Overview

The ATTINY12L-4PI is an 8-bit microcontroller based on the AVR RISC architecture, manufactured by Microchip Technology. It features 1K byte of in-system programmable Flash program memory and 64 bytes of EEPROM data memory. The device operates within a voltage range of 2.7V to 5.5V with a maximum clock frequency of 4MHz. It includes 32 general-purpose working registers, six I/O lines, an 8-bit Timer/Counter, an analog comparator, and a programmable watchdog timer. The component is housed in an 8-pin PDIP package.

Feature Summary

• High-performance 8-bit RISC architecture with single-clock-cycle instruction execution
• Nonvolatile memory including 1K Flash and 64B EEPROM with high endurance ratings
• Integrated peripheral features such as an analog comparator and programmable watchdog timer
• Low-power operation with selectable idle and power-down sleep modes

Applications

• Embedded control applications requiring low power consumption
• Battery-powered devices utilizing internal RC oscillator
• Systems requiring in-system programming via SPI port

Procurement Notes

Verify that the specific ordering suffix corresponds to the industrial temperature range (-40°C to 85°C) and the PDIP package type. Confirm the speed grade matches the required operational frequency limits for your design. Ensure compliance with RoHS directives if lead-free packaging is specified. Cross-reference the manufacturer's current documentation to confirm the device status, as this family may be marked as not recommended for new designs.

Selection Notes

Select this component when a cost-effective 8-bit solution with minimal I/O requirements is needed. The ATtiny12L variant supports lower supply voltages compared to standard ATtiny12 models. Consider the available peripherals like the analog comparator and timer if signal conditioning or timing functions are required without external components. Evaluate the trade-off between processing speed and power consumption inherent to the AVR core architecture.

Part Context

This part belongs to the ATtiny11/12 family of 8-bit microcontrollers. These devices utilize Atmel's high-density nonvolatile memory technology combined with a RISC CPU. The family offers flexibility through various speed grades and voltage ranges, catering to different embedded control needs while maintaining compatibility across the series regarding instruction sets and register structures.

Replacement Considerations

Compatible substitutes include other variants from the ATtiny11/12 family such as ATtiny12L-4PU or ATtiny12L-4SI, provided the package and temperature range match. Verify pinout compatibility and electrical specifications before substitution.
