AVR128DB32-I/PT

Overview

The AVR128DB32-I/PT is an 8-bit microcontroller from the AVR DB family, featuring a hardware multiplier CPU running at up to 24 MHz. It includes 128 KB of Flash memory, 16 KB of SRAM, and 512 bytes of EEPROM. The device operates within a supply voltage range of 1.8V to 5.5V and supports industrial temperatures from -40°C to 85°C. It provides up to 55 programmable I/O pins in a 32-pin TQFP package.

Feature Summary

Features Multi-Voltage I/O (MVIO) on Port C with selectable input voltage thresholds for flexible interfacing.
Integrates advanced analog subsystems including a differential ADC, op amps, and configurable custom logic.
Supports CPU-independent inter-peripheral signaling through a dedicated Event System.

Applications

Embedded systems requiring multi-voltage I/O compatibility
Applications utilizing analog signal conditioning and precision measurement
Industrial control designs needing robust peripheral integration

Procurement Notes

Verify the specific ordering suffix against official Microchip documentation to confirm package type and temperature grade. Ensure the component matches the required pin count and memory configuration for your design. Cross-reference datasheet revision numbers to validate feature availability and errata status before finalizing procurement.

Selection Notes

Select this model when 128 KB of program memory and 16 KB of data RAM are required alongside a 32-pin footprint. It is suitable for designs needing high-speed analog peripherals and event-driven processing without external components. Verify that the 24 MHz clock speed meets the timing requirements of the target application.

Part Context

This component belongs to the AVR DB family, which offers vertical migration capabilities without code modification across different pin counts. It shares architectural similarities with other devices in the series but is distinguished by its specific 128 KB Flash capacity and 32-pin physical interface.
