AVR16EB28T-E/STX

Overview

The AVR16EB28T-E/STX is an 8-bit microcontroller from the AVR EB Family, featuring a 20 MHz AVR CPU with hardware multiplier. It includes 16 KB of Flash memory with read-while-write capability, 2 KB of SRAM, and 512 bytes of EEPROM. The device operates within a supply voltage range of 1.8 V to 5.5 V and supports extended temperature ranges (-40°C to +125°C). Key peripherals include a 12-bit differential ADC with PGA, two analog comparators, multiple timers (TCB, TCE, TCF), USART, SPI, TWI/I2C, and a Configurable Custom Logic block.

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 functions.
• Supports vertical migration without code modification due to full pin and feature compatibility within the family.
• Provides advanced digital peripherals including Waveform Extension (WEX) and Configurable Custom Logic Look-up Tables.

Applications

• Embedded control systems requiring low-power operation
• Applications utilizing precise analog signal processing with differential ADC inputs
• Industrial environments necessitating extended temperature range reliability
• Systems requiring flexible peripheral configuration via Event System and CCL

Procurement Notes

Verify the specific ordering suffixes against official Microchip documentation to confirm package type and temperature rating. Ensure that the 'T' suffix indicates tape and reel packaging and 'STX' denotes the VQFN28 package. Confirm that the 'E' suffix corresponds to the extended industrial temperature range specifications required for your application environment before finalizing procurement.

Selection Notes

Select this component when an 8-bit AVR solution with high analog precision and event-driven architecture is needed. Consider the 28-pin VQFN package for space-constrained designs. Evaluate the need for read-while-write Flash operations and the specific I/O count provided by the 28-pin variant compared to other family members like the AVR16EB20 or AVR16EB32.

Part Context

This part belongs to the AVR EB Family, which utilizes the latest technology from Microchip Technology. The family emphasizes flexibility through vertical and horizontal migration capabilities. The AVR16EB28 specifically offers a balance of memory size and I/O availability in a compact 28-pin form factor, sharing core architectural features with the AVR16EB14, AVR16EB20, and AVR16EB32 devices.

Replacement Considerations

For pin-compatible replacements within the same family, consider the AVR16EB28-I/STX for industrial temperature range applications. Verify that any substitute maintains the same package style (VQFN28) and memory configuration (16 KB Flash, 2 KB SRAM).
