AVR16EB20-I/SS

Overview

The AVR16EB20-I/SS is an 8-bit microcontroller from the AVR EB family, featuring a 20-pin SSOP package and industrial temperature range (-40°C to +85°C). It utilizes an AVR CPU with hardware multiplier running at up to 20 MHz. Memory includes 16 KB of Flash with read-while-write capability, 2 KB of SRAM, and 512 bytes of EEPROM. The device provides 17 general-purpose I/O pins and integrates a 12-bit differential ADC with 14 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.

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 analog comparators.
• Supports vertical migration within the AVR EB family without code modification due to full pin and feature compatibility.
• Integrates advanced digital peripherals including Configurable Custom Logic Look-up Tables and automated CRC Flash program memory scan.

Applications

• Embedded systems requiring low-power operation and high precision analog signal processing.
• Industrial control applications utilizing the event system for predictable peripheral interaction.
• Prototyping and development using vertically compatible AVR EB family devices.

Procurement Notes

Verify the specific ordering suffix against official Microchip documentation to confirm package type and temperature rating. Ensure the component matches the required industrial specifications for your application environment. Cross-reference the datasheet revision to confirm all technical parameters align with current manufacturing standards before finalizing procurement decisions.

Selection Notes

Select this model when a 20-pin SSOP package is required for the AVR EB family. It is suitable for designs needing 16 KB of Flash and 17 I/O pins. Consider the extended temperature variant if ambient conditions exceed standard industrial limits. Verify that the 12-bit ADC resolution meets the specific signal acquisition requirements of the target application.
