AVR16EB28T-I/STX

Overview

The AVR16EB28T-I/STX is an 8-bit microcontroller from the AVR EB Family, featuring a 16 KB Flash program memory, 2 KB SRAM, and 512 bytes of EEPROM. It operates at a maximum clock frequency of 20 MHz with a supply voltage range of 1.8 V to 5.5 V. The device includes a 12-bit differential ADC with 20 channels, two 16-bit Timer/Counters type B (TCB), one Timer/Counter type E (TCE) with Waveform Extension, and one Timer/Counter type F (TCF). Communication interfaces include USART, SPI, and TWI/I2C. It utilizes a VQFN-28 package and supports industrial temperature ranges.

Feature Summary

• Features a flexible low-power architecture with an Event System for CPU-independent inter-peripheral signaling.
• Includes accurate analog subsystems such as a 12-bit differential ADC with programmable gain amplifier and dual analog comparators.
• Supports vertical migration within the family without code modification due to full pin and feature compatibility.
• Provides advanced digital peripherals including Configurable Custom Logic Look-up Tables and automated CRC scan.

Applications

• General-purpose embedded control systems requiring multi-voltage I/O capabilities.
• Applications utilizing analog signal conditioning with differential ADC inputs.
• Industrial environments operating within specified temperature ranges.
• Systems requiring precise timing via hardware timers and waveform extension features.

Procurement Notes

Verify the specific ordering suffix STX corresponds to the VQFN-28 package style and T tape & reel carrier type as defined in the datasheet designation table. Confirm that the 'I' suffix indicates the Industrial temperature range (-40°C to +85°C). Ensure the component matches the preliminary data sheet specifications before integration into production designs.

Selection Notes

Select this model when 28 pins are required alongside 16 KB of Flash memory. It is suitable for designs needing multiple analog channels and advanced timer configurations. Consider the VQFN-28 package for space-constrained surface-mount applications. Verify compatibility with existing AVR EB Family codebases if migrating from other pin counts.

Part Context

This component belongs to the AVR16EB14/20/28/32 series within the AVR EB Family. These devices share a common core architecture and peripheral set, differing primarily in pin count and available I/O resources. The family emphasizes low power consumption and high performance through hardware acceleration features like the single-cycle multiplier.

Replacement Considerations

Devices within the same AVR EB Family offering different pin counts may serve as alternatives if I/O requirements change. Vertical migration allows code reuse across the series. Check specific pinout differences and peripheral availability on alternative models to ensure functional equivalence.
