ATTINY13V-10MU

Overview

The ATTINY13V-10MU is an 8-bit AVR microcontroller manufactured by Microchip Technology, formerly Atmel. It features a 1KB in-system programmable Flash memory, 64 bytes of EEPROM, and 64 bytes of SRAM. The device operates within a voltage range of 1.8V to 5.5V and supports a maximum clock frequency of 10MHz. It utilizes the picoPower technology for low-power consumption, offering idle, noise reduction, and power-down modes. The component includes a 4-channel 10-bit ADC, an 8-bit timer/counter with PWM capabilities, and SPI/TWI interfaces. It is housed in a 20-pin MLF/QFN package and supports industrial temperature ranges from -40°C to +85°C.

Feature Summary

• Integrates picoPower technology enabling dynamic clock frequency adjustment for optimized power-performance balance.
• Supports system-in-programming via SPI interface and on-chip debugging through debugWIRE functionality.
• Includes a 4-channel 10-bit analog-to-digital converter with internal voltage reference options.
• Features an 8-bit timer/counter with two PWM channels and a programmable watchdog timer.

Applications

• Low-power embedded control systems
• Battery-operated sensor nodes
• Simple motor control applications
• Consumer electronics requiring minimal I/O

Procurement Notes

Verify the specific suffix 'MU' corresponds to the 20-pin MLF/QFN package variant when sourcing. Confirm RoHS compliance status as required by project specifications. Ensure the supplier provides official datasheets matching the ATTINY13V-10MU designation to avoid confusion with other pinout configurations like PDIP or SOIC variants. Check for any end-of-life notices or obsolescence warnings directly from Microchip Technology before finalizing procurement plans.

Selection Notes

Select this component when a compact 20-pin surface-mount solution is required for basic AVR-based control tasks. It is suitable for designs needing multiple I/O lines compared to smaller packages while maintaining low power characteristics. Consider the 10MHz speed limit and limited memory if complex algorithms are anticipated. Evaluate the thermal performance of the MLF/QFN package against the application's environmental constraints.

Part Context

This part belongs to the ATtiny13 family of 8-bit AVR microcontrollers. It shares the same core architecture and peripheral set as other ATTINY13 variants but differs primarily in packaging and pin count. The 'V' indicates low-voltage operation capability, while '10' denotes the 10MHz speed grade. It serves as a cost-effective alternative to larger AVR families for simple standalone applications.

Replacement Considerations

Direct substitutes include ATTINY13V-10MMU (same package) or ATTINY13V-10SU (SOIC-8, requires schematic revision). Cross-referencing with ATTINY13A series may require firmware adjustments due to minor electrical characteristic differences. Verify pin compatibility before replacing ATTINY13V-10PU (PDIP) due to significant form factor changes.
