ATTINY28L-4PC

Overview

The ATtiny28L-4PC is an 8-bit microcontroller based on the AVR RISC architecture, manufactured by Microchip Technology. It features 2K bytes of Flash program memory with 1,000 write/erase cycle endurance and operates at speeds up to 4 MHz. The device supports a supply voltage range of 2.7V to 5.5V and includes 11 programmable I/O lines. Key peripherals include an 8-bit Timer/Counter, an on-chip Analog Comparator, a Programmable Watchdog Timer, and a high-current LED driver. It utilizes a 28-lead PDIP package.

Feature Summary

• Executes powerful instructions in a single clock cycle for efficient processing.
• Integrates a built-in high-current LED driver with programmable modulation capabilities.
• Supports low-power Idle and Power-down modes to optimize energy consumption.
• Features interrupt and wake-up functionality triggered by low-level inputs.

Applications

• Embedded control systems requiring low power consumption
• Applications utilizing the integrated high-current LED driver
• Systems requiring analog signal comparison via the on-chip comparator

Procurement Notes

Verify the specific speed grade and operating temperature range required for your application against the datasheet specifications. Confirm that the 28-lead PDIP package aligns with your PCB layout constraints. Ensure the 2.7V to 5.5V supply voltage range matches your system's power design before finalizing procurement.

Selection Notes

Select this component if your design requires a cost-effective 8-bit solution with integrated LED driving capabilities. Consider the ATtiny28L variant specifically for applications needing operation up to 4 MHz within the 2.7V to 5.5V voltage range. Evaluate the available I/O lines and peripheral set against your functional requirements.

Part Context

This part belongs to the ATtiny28 family of 8-bit microcontrollers. The 'L' suffix indicates the 2.7V to 5.5V operating voltage range, distinguishing it from the 'V' series which supports lower voltages down to 1.8V. The '4' denotes the maximum clock frequency of 4 MHz, while 'PC' specifies the 28-lead PDIP package type.
