ATTINY84-15MZ

Overview

The ATTINY84-15MZ is an 8-bit AVR microcontroller featuring 8KB of in-system programmable Flash memory, 512 bytes of EEPROM, and 512 bytes of SRAM. It operates at a maximum clock frequency of 15MHz with a supply voltage range of 1.8V to 5.5V. The device includes 12 I/O lines, an 8-channel 10-bit ADC, USI interface, and multiple timers. It is housed in a compact 20-VQFN package suitable for space-constrained applications.

Feature Summary

• High-performance 8-bit AVR architecture with single-cycle instruction execution
• Integrated non-volatile memory including Flash, EEPROM, and SRAM
• Built-in analog-to-digital converter with multiple channels
• Supports low-power operation modes and internal watchdog timer

Applications

• Battery-powered sensor nodes
• Simple motor control systems
• Consumer electronics peripherals
• Industrial monitoring devices

Procurement Notes

Verify the specific suffix '15MZ' against official Microchip documentation to confirm the exact speed grade and package variant. Ensure compatibility with existing PCB footprints for the 20-VQFN form factor. Confirm RoHS compliance status through current datasheets before finalizing procurement specifications.

Selection Notes

Select this component when a balance of processing speed and power efficiency is required for 8-bit control tasks. The 15MHz rating offers sufficient throughput for most embedded applications while maintaining low energy consumption. Consider the available I/O count and peripheral set against system requirements.

Part Context

This part belongs to the ATtiny family of 8-bit microcontrollers based on the AVR RISC core. It shares architectural similarities with other members like the ATtiny24/44 series but provides enhanced memory capacity. The family is known for high code density and efficient power management capabilities.

Replacement Considerations

Check for direct pin-compatible alternatives within the ATtiny series such as the ATtiny84A if higher speed grades are acceptable. Verify that any substitute maintains the same VQFN package dimensions and electrical characteristics.
