AVR64DA28S-I/SP

Overview

The AVR64DA28S-I/SP is an 8-bit microcontroller from the AVR DA series, manufactured by Microchip Technology. It features a 28-pin SPDIP package and utilizes the AVR CPU core with a hardware multiplier. The device operates at clock speeds up to 24 MHz across a supply voltage range of 1.8V to 5.5V. Key specifications include 64kB of Flash program memory, 8kB of SRAM, and 512B of EEPROM. It integrates ten 12-bit ADC channels, one 10-bit DAC, three analog comparators, and multiple communication interfaces including USART, SPI, and TWI.

Feature Summary

Multi-voltage I/O capability allowing operation across the full 1.8V to 5.5V supply range without level shifting.
Integrated analog signal conditioning peripherals including programmable gain amplifiers and digital filters for precise sensor interfacing.
High-performance real-time control features supported by a hardware multiplier and advanced timer/counters with PWM outputs.

Applications

Industrial control systems requiring robust multi-voltage interface capabilities
Smart home appliances and IoT devices needing efficient power management and analog sensing
Automotive applications utilizing the wide operating temperature range and reliable MCU architecture

Procurement Notes

Verify the specific suffix 'S' in the part number against official Microchip documentation to confirm package type and availability. Ensure the industrial temperature grade (-40°C to +85°C) matches your environmental requirements. Cross-reference the datasheet revision date to confirm peripheral functionality and errata status before finalizing procurement plans.

Selection Notes

Select this component when a balance of moderate flash memory (64kB) and extensive analog peripherals is required. The AVR DA series is suitable for designs needing high-speed ADC sampling and flexible I/O voltage levels. Consider pin count and package constraints, as the 28-pin SPDIP limits available GPIOs compared to larger packages in the same family.

Part Context

This microcontroller belongs to the AVR DA family, which emphasizes analog performance and multi-voltage operation within the 8-bit AVR ecosystem. It shares architectural similarities with the DB series but offers distinct peripheral configurations tailored for cost-sensitive yet feature-rich embedded applications. The DA series targets modern industrial and consumer electronics markets.
