ATTINY807-MF

Overview

The ATtiny807-MF is an 8-bit microcontroller from the Microchip tinyAVR 0-series, featuring a hardware multiplier and operating at frequencies up to 20 MHz. It integrates 16 KB of in-system self-programmable Flash memory, 512 bytes of SRAM, and 256 bytes of EEPROM. The device utilizes a 24-pin VQFN package and supports industrial temperature ranges. Key specifications include a 10-bit ADC with multiple voltage references, a Real-Time Counter (RTC), and a single-pin Unified Program and Debug Interface (UPDI).

Feature Summary

• Features a flexible low-power architecture with Core Independent Peripherals (CIPs) and an Event System for CPU-independent inter-peripheral signaling.
• Includes Configurable Custom Logic (CCL) with programmable look-up tables and automated CRC memory scan capabilities.
• Supports three sleep modes: Idle, Standby, and Power-Down with full data retention.
• Provides versatile communication interfaces including USART, SPI, and TWI.

Applications

• Industrial control systems requiring reliable operation across wide temperature ranges.
• Battery-powered devices utilizing low-power architectures and sleep modes.
• Applications necessitating precise analog sensing via the integrated ADC and voltage references.
• Systems requiring robust memory integrity checks through automated CRC scanning.

Procurement Notes

Verify that the specific ordering suffix matches the required package type and temperature grade. Confirm the device status as active or recommended for new designs before procurement. Ensure compatibility with existing UPDI programming tools and debuggers. Check for any specific silicon errata documentation relevant to the manufacturing lot.

Selection Notes

Select this component when 16 KB of program memory and 256 bytes of EEPROM are required within a compact 24-pin footprint. Consider the ATtiny807-MF for applications needing high-speed processing up to 20 MHz alongside advanced analog features. Evaluate the power consumption characteristics against system requirements to optimize battery life.

Part Context

This part belongs to the tinyAVR 0-series family, designed for cost-sensitive and space-constrained embedded applications. It shares architectural similarities with other members like the ATtiny806 and ATtiny1607 but offers distinct memory configurations. The series emphasizes low power consumption and peripheral flexibility.

Replacement Considerations

Direct substitutes within the same package and pinout include the ATtiny806 and ATtiny1607, provided memory requirements align. Cross-referencing with the ATtiny3217 series may be necessary if additional I/O lines or different memory sizes are needed.
