Overview
The AVR128DB48T-I/6LX is an 8-bit microcontroller from the AVR DB family, featuring a 128 KB Flash program memory, 16 KB SRAM, and 512 bytes of EEPROM. It operates at clock speeds up to 24 MHz with a supply voltage range of 1.8 V to 5.5 V. The device includes a 12-bit differential ADC with 18 channels, a 10-bit DAC, three analog comparators, and multiple timers including TCA, TCB, and TCD. Communication interfaces include USART, SPI, and TWI/I2C.
Feature Summary
- Multi-Voltage I/O (MVIO) on Port C allows flexible input voltage thresholds for mixed-voltage systems.
- Configurable Custom Logic (CCL) provides programmable Look-up Tables for custom digital logic without CPU intervention.
- Event System enables CPU-independent inter-peripheral signaling for predictable and efficient data transfer.
Applications
- Industrial control systems requiring multi-voltage I/O compatibility
- Battery-powered devices utilizing low-power sleep modes and RTC
- Applications needing precise analog signal conditioning with differential ADC
Procurement Notes
Verify the specific ordering suffix against official Microchip documentation to confirm package type and temperature grade. Ensure the component matches the required industrial temperature range and pinout configuration for your PCB design. Cross-reference the datasheet revision to confirm peripheral availability and electrical characteristics.
Selection Notes
Select this model when 128 KB of Flash and 16 KB of SRAM are required within a 48-pin package. Consider the AVR128DB48 variant if vertical migration within the DB family is needed. Evaluate the MVIO capabilities if interfacing with different voltage domains is necessary.
Part Context
This component belongs to the AVR128DB series, part of the broader AVR DB family. These devices share a common architecture with varying pin counts and memory sizes, allowing for horizontal and vertical migration. The 48-pin version offers a balance between I/O count and memory capacity.
