ATTINY24V-10MU

Overview

The Atmel ATTINY24V-10MU is an 8-bit AVR microcontroller featuring a 20-pin MLF/QFN package. It includes 2 kB of in-system programmable Flash, 128 bytes of EEPROM, and 128 bytes of SRAM. The device supports a maximum clock frequency of 10 MHz with a supply voltage range of 1.8 V to 5.5 V. Key peripherals include one 8-bit timer/counter with two PWM channels, a 10-bit ADC with four single-ended channels, a USI interface supporting SPI/TWI protocols, and an on-chip analog comparator.

Feature Summary

• AVR enhanced RISC architecture with most instructions executing in a single clock cycle
• Integrated picoPower technology for dynamic low-power mode switching
• On-chip debugWIRE system for in-circuit debugging and programming
• Universal Serial Interface (USI) supporting both SPI and TWI communication protocols

Applications

• Battery-powered consumer electronics requiring extended standby life
• Industrial control systems operating within industrial temperature ranges
• Sensor management nodes utilizing the integrated ADC and comparators
• IoT terminal devices needing compact surface-mount packaging

Procurement Notes

Verify that the specific part number suffix corresponds to the MLF or QFN package variant, as pin counts and dimensions differ from SOIC or PDIP versions. Confirm the 'V' suffix indicates the 1.8V minimum operating voltage requirement rather than the standard 2.7V threshold. Ensure the order quantity matches distributor minimums and check for RoHS compliance documentation if required by your manufacturing standards.

Selection Notes

Select this component when a balance between code capacity and physical footprint is required. The 20-pin QFN/MLF form factor suits space-constrained designs compared to the 14-pin variants. Choose this model over higher-memory ATtiny series parts if the application logic fits within 2 kB of Flash. Verify that the 10-bit ADC resolution meets signal processing needs before considering alternatives with higher precision requirements.

Part Context

This microcontroller belongs to the ATtiny family, which utilizes the AVR core architecture known for high efficiency per megahertz. The ATTINY24V-10MU specifically targets applications where moderate program storage and I/O flexibility are necessary without the complexity of larger MCU families. It shares architectural similarities with the ATTINY25 and ATTINY261 but offers distinct pin configurations suitable for different board layouts.

Replacement Considerations

Publicly confirmed substitutes include ATTINY24A-10MU and ATTINY24V-10SU. Verify package compatibility when swapping between MLF/QFN and SOIC types. Cross-reference electrical specifications to ensure voltage thresholds align with existing power rails.
