Overview
The AVR64DA48S-I/6MX is an 8-bit microcontroller from the AVR DA series, featuring a 64 kB Flash program memory and 8 kB SRAM. It operates with a maximum clock frequency of 24 MHz and supports a supply voltage range of 1.8 V to 5.5 V. The device includes a 12-bit ADC with multiple channels, three comparators, a DAC, six UARTs, two SPI interfaces, and TWI. It utilizes a 48-pin VQFN (6x6) package and functions within a temperature range of -40°C to +85°C.
Feature Summary
- Integrates high-resolution analog peripherals including a 12-bit ADC and DAC for precise signal processing.
- Provides extensive communication capabilities with multiple UART, SPI, and TWI interfaces.
- Features programmable logic blocks such as comparators and zero-crossing detectors for control applications.
Applications
- Industrial sensor nodes requiring multi-protocol connectivity
- Smart metering devices with analog input requirements
- Motor control systems utilizing zero-crossing detection
Procurement Notes
Verify the specific suffix 'S' indicates tube packaging when ordering, distinct from tape-and-reel variants. Confirm the operating temperature grade 'I' matches environmental requirements. Ensure the 48-pin VQFN footprint aligns with PCB design constraints. Cross-reference datasheet errata for any silicon revisions affecting peripheral behavior.
Selection Notes
Select this model for designs needing high I/O count in a compact surface-mount package. The 24 MHz speed and 64 kB memory suit complex logic tasks. Compare against AVR EA or DB series if extended temperature ranges or different analog features are required. Validate pin compatibility if migrating from other AVR DA family members.
Part Context
This component belongs to the Microchip AVR DA family, designed for cost-sensitive 8-bit applications. It shares architectural similarities with AVR EA and DB series but offers specific peripheral combinations like six UARTs. The DA series targets general-purpose control and communication tasks in consumer and industrial electronics.
Replacement Considerations
AVR64DA48-I/PT offers identical core specifications in a TQFP-48 package. AVR64DA48T-I/PT provides the same functionality in a tape-and-reel format. Verify package dimensions and pinout compatibility before substitution.
