AVR16EB28-E/STX

Overview

The AVR16EB28-E/STX is an 8-bit microcontroller from the AVR EB Family, featuring a 20 MHz AVR CPU with hardware multiplier. It includes 16 KB of Flash memory with read-while-write capability, 2 KB of SRAM, and 512 bytes of EEPROM. The device operates within a supply voltage range of 1.8 V to 5.5 V and supports extended temperature ranges up to +125°C. Key peripherals include a 12-bit ADC with PGA, two analog comparators, TWI/I2C, SPI, USART, and multiple timer/counters.

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 window compare functions.
Supports advanced digital peripherals including Configurable Custom Logic (CCL) Look-up Tables and Waveform Extension (WEX).
Provides single-pin Unified Program and Debug Interface (UPDI) for programming and debugging.

Applications

Industrial control systems requiring robust peripheral integration.
Battery-powered devices utilizing low-power sleep modes.
Sensor interfaces leveraging high-resolution ADC and analog comparators.
Communication nodes using USART, SPI, or TWI/I2C protocols.

Procurement Notes

Verify the specific ordering suffix 'E' confirms the extended temperature rating of -40°C to +125°C. Confirm the 'STX' suffix corresponds to the VQFN28 package style. Ensure compatibility with existing design footprints for the VQFN28 package. Check for any preliminary status updates in the latest datasheet revisions before finalizing procurement.

Selection Notes

Select this component when vertical migration within the AVR EB family is required without code modification. Choose this part if an extended temperature range up to +125°C is necessary for the application environment. Consider this device for designs needing a balance of analog precision with a 12-bit ADC and digital flexibility via CCL.

Part Context

This device belongs to the AVR EB Family, which offers pin and feature compatibility across variants. It shares architectural similarities with other members like the AVR16EB32 and AVR32EB28, allowing for horizontal or vertical migration based on pin count and memory requirements.
