AVR16EB32-E/PT

Overview

The AVR16EB32-E/PT is an 8-bit microcontroller from the AVR EB family, featuring a 16 KB Flash memory with read-while-write capability, 2 KB SRAM, and 512 bytes of EEPROM. It operates at a maximum clock frequency of 20 MHz and supports a supply voltage range of 1.8 V to 5.5 V. The device includes a 12-bit ADC with 24 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 is housed in a TQFP-32 package and rated for extended temperature operation from -40°C to +125°C.

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 AVR EB family without code modification due to full pin and feature compatibility.
• Provides advanced digital peripherals including Configurable Custom Logic (CCL) with Look-up Tables and CRCSCAN.

Applications

• Industrial control systems requiring extended temperature stability
• Battery-powered devices utilizing low-power sleep modes
• Sensor interface applications using the high-resolution ADC
• Motor control implementations leveraging TCE and WEX

Procurement Notes

Verify the ordering suffix 'E' confirms the extended temperature range (-40°C to +125°C) and 'PT' indicates the TQFP-32 package. Confirm the datasheet revision matches the design requirements, as preliminary documents may undergo updates. Ensure the specific variant aligns with the required I/O count and peripheral availability for the target application.

Selection Notes

Select this component when extended industrial temperature ratings are necessary compared to the standard industrial version. The 16 KB Flash size suits applications with moderate code complexity. Consider the TQFP-32 package if through-hole or larger pitch surface-mount assembly is preferred over VQFN options available in the same family.

Part Context

This part belongs to the AVR EB family, which shares architectural similarities with other AVR microcontrollers but introduces enhanced features like the Event System and CCL. It offers horizontal and vertical migration paths within the family, allowing designers to scale pin counts and memory sizes while maintaining software compatibility across different package types.

Replacement Considerations

AVR16EB32-I/PT serves as the industrial temperature variant replacement. For package changes, AVR16EB32-E/RXB provides the same electrical specifications in a VQFN-32 package.
