AVR16EB28-I/SP

Overview

The AVR16EB28-I/SP is an 8-bit microcontroller from the AVR EB Family, utilizing the AVR CPU with a hardware multiplier. It features 16 KB of Flash memory, 2 KB of SRAM, and 512 bytes of EEPROM. The device operates at clock speeds up to 20 MHz within a supply voltage range of 1.8 V to 5.5 V. It includes a 12-bit differential ADC with 20 channels, two analog comparators, and multiple timers including TCB, TCE, TCF, and RTC. The component is housed in a 28-pin SPDIP package and supports industrial temperature ranges.

Feature Summary

• Supports vertical migration without code modification across the AVR EB family due to pin and feature compatibility.
• Integrates an Event System for CPU-independent inter-peripheral signaling and Configurable Custom Logic (CCL).
• Features a 12-bit differential ADC with programmable gain amplifier and dual-mode TWI/I2C interface.
• Includes a single-pin Unified Program and Debug Interface (UPDI) for programming and debugging.

Applications

• Low-power embedded control systems requiring vertical migration capabilities.
• Applications utilizing event-driven architectures for predictable peripheral signaling.
• Systems requiring precise analog signal conditioning with differential ADC inputs.
• Industrial environments operating within extended temperature ranges.

Procurement Notes

Verify the specific ordering suffix against official Microchip documentation to confirm package style and temperature range. Ensure the procurement channel sources genuine components matching the datasheet specifications. Confirm availability of technical support resources such as datasheets and errata sheets for the AVR16EB28-I/SP variant prior to finalizing acquisition.

Selection Notes

Select this component when a 28-pin through-hole package is required for the AVR EB family. Choose this model over variants with different pin counts if the application demands the specific I/O count and peripheral set provided by the 28-pin configuration. Consider the industrial temperature rating and SPDIP form factor for prototyping or legacy board designs.

Part Context

This part belongs to the AVR EB Family, which emphasizes low power consumption and flexible architecture. The family allows horizontal migration to reduce pin counts or vertical migration to increase them while maintaining software compatibility. The AVR16EB28 specifically bridges the gap between smaller 20-pin devices and larger 32-pin options in terms of I/O availability.
