ATTINY28V-1MI

Overview

The ATTINY28V-1MI 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 utilizes a 32-pad MLF package with dimensions of 5x5x1.0 mm and a lead pitch of 0.50mm. The component is rated for industrial operating temperatures ranging from -40°C to +85°C.

Feature Summary

• Executes powerful instructions in a single clock cycle for efficient processing
• Integrates nonvolatile Flash program memory with write/erase endurance
• Includes built-in high-current LED driver with programmable modulation
• Supports low-power Idle and Power-down modes for energy conservation

Applications

• Embedded control applications requiring low power consumption
• Systems utilizing interrupt and wake-up on low-level input
• Devices employing programmable watchdog timers with internal oscillators

Procurement Notes

Verify the specific ordering code ATTINY28V-1MI against official Microchip documentation to confirm package type and speed grade. Ensure compatibility with industrial temperature ranges (-40°C to +85°C) and voltage requirements (1.8V - 5.5V). Confirm that the 32-pad MLF package matches design constraints. Check for any RoHS compliance details or halide-free status if required by manufacturing standards.

Selection Notes

Select this component when a low-cost, low-power 8-bit solution is needed with integrated LED driving capabilities. The 1.2 MHz speed grade suits applications where minimal power usage is critical compared to higher-speed variants. Consider the MLF package for space-constrained designs requiring surface-mount assembly. Verify that the absence of ADC and limited timer count meets functional requirements.

Part Context

This part belongs to the ATtiny28 family, which combines an enhanced RISC 8-bit CPU with Flash memory on a monolithic chip. The V suffix indicates operation down to 1.8V, distinguishing it from the L variant which starts at 2.7V. The MI suffix denotes the industrial temperature range and MLF package. This family targets cost-effective embedded control solutions using the AVR architecture.
