ATTINY48V-6MMU

Overview

The ATTINY48V-6MMU is an 8-bit AVR microcontroller featuring a 12 MHz RISC core, 4 KB in-system programmable Flash, 512 B EEPROM, and 512 B SRAM. It operates within a voltage range of 1.8 V to 5.5 V and supports up to 32 programmable I/O lines. The device integrates multiple peripherals including two 8-bit Timer/Counters with PWM, one 16-bit Timer/Counter, a 10-bit ADC with 8 channels, an analog comparator, and USI for SPI/TWI communication. It utilizes a 28-pin MLF/QFN package.

Feature Summary

• Integrates picoPower technology for low-power operation across various sleep modes.
• Includes enhanced on-chip debug capabilities via the debugWIRE interface.
• Features flexible non-volatile memory options with high endurance ratings.

Applications

• Battery-powered consumer electronics
• Industrial control systems
• Smart home devices

Procurement Notes

Verify the specific suffix 'V' indicates the extended 1.8V operating voltage range compared to standard variants. Confirm the 'MU' designation corresponds to the 28-lead MLF/QFN package type. Ensure the speed grade matches the required system clock frequency for your application design constraints.

Selection Notes

Select this component when a balance of processing power and peripheral integration is needed in a compact form factor. The 1.8V minimum supply voltage makes it suitable for battery-operated applications requiring extended runtime. Consider the available I/O count and ADC channels against project requirements before choosing alternative pin counts.

Part Context

This part belongs to the ATtinyAVR family, known for high performance and low power consumption. It represents a legacy device series from Atmel, now maintained by Microchip Technology. These controllers are widely used in cost-sensitive embedded applications where small size and efficient resource usage are critical design factors.

Replacement Considerations

Check for direct pin-compatible upgrades within the ATtiny48 series or newer AVR XMEGA families if enhanced features are required. Verify software compatibility when migrating between different AVR architectures.
