Overview
The ATTINY28V-1MC is an 8-bit microcontroller based on the AVR RISC architecture, manufactured by Microchip Technology. It features 2K bytes of Flash program memory and operates within a voltage range of 1.8V to 5.5V. The device supports a maximum clock frequency of 1.2 MHz and includes 11 programmable I/O lines. It is housed in a 32-pad MLF package with dimensions of 5x5x1.0 mm body size and a lead pitch of 0.50mm.
Feature Summary
- Utilizes high-performance AVR RISC architecture with most instructions executing in a single clock cycle.
- Includes a built-in high-current LED driver with programmable modulation capabilities.
- Features interrupt and wake-up functionality triggered by low-level input signals.
- Integrates an on-chip analog comparator and a programmable watchdog timer.
Applications
- Embedded control applications requiring low power consumption
- Systems utilizing the high-current LED driver for display or indicator functions
- Battery-powered devices operating within the specified voltage range
Procurement Notes
Verify the specific ordering code ATTINY28V-1MC against official Microchip documentation to confirm package type and speed grade. Ensure compatibility with the required operating temperature range and voltage specifications before integration into the design.
Selection Notes
Select this component for designs requiring a cost-effective 8-bit solution with integrated LED driving capabilities. Consider the 1.2 MHz speed grade and 1.8V minimum supply voltage when evaluating system performance and power requirements.
Part Context
This part belongs to the ATtiny28 family, which also includes variants like the ATtiny28L. The 'V' suffix indicates the 1.8V - 5.5V operating voltage range, while '1M' denotes the 1.2 MHz speed grade. The 'C' suffix typically refers to the commercial temperature range (0°C to 70°C).
Replacement Considerations
Check for direct substitutes within the ATtiny28 series, such as ATTINY28V-1MU or ATTINY28V-1MC from other manufacturers if available. Verify pinout and electrical characteristics match exactly before substitution.
