AVR16EB14T-E/ST

Overview

The AVR16EB14T-E/ST is an 8-bit microcontroller from Microchip Technology featuring the AVR core. It integrates 16 KB of Read-While-Write flash memory and 2 KB of SRAM within a TSSOP-14 package. The device supports a maximum clock frequency of 20 MHz and operates on a supply voltage range of 1.8 V to 5.5 V. Key peripherals include a 12-bit ADC, Programmable Gain Amplifier (PGA), UART, SPI, I2C interfaces, two Timer/Counter B modules, and Windowed Extended Watchdog features.

Feature Summary

• Integrates 12-bit Analog-to-Digital Converter with Programmable Gain Amplifier for high-resolution signal acquisition.
• Supports Read-While-Write execution to maintain code continuity during flash memory modifications.
• Includes multiple communication interfaces such as UART, SPI, and I2C for versatile system connectivity.
• Features specialized timer modules including Timer/Counter B and Windowed Extended Watchdog for precise control.

Applications

• Industrial sensor nodes requiring high-resolution analog input processing
• Battery-powered devices utilizing low-voltage operation capabilities
• Embedded systems needing non-volatile data storage with runtime updates
• Communication gateways utilizing serial interface protocols

Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging when ordering. Confirm the '-E' designation corresponds to the extended temperature range specifications required for your application environment. Ensure compatibility with the TSSOP-14 footprint during PCB layout finalization. Cross-reference the latest datasheet revision for any silicon errata or functional clarifications before production implementation.

Selection Notes

Select this component when a balance of moderate program memory and high-resolution analog conversion is required in a compact package. The inclusion of PGA allows for direct amplification of small sensor signals without external components. Consider the 20 MHz performance limit against your processing requirements. Evaluate the availability of sufficient I/O pins within the 14-pin constraint for your peripheral connections.

Part Context

This part belongs to the AVR EB series, designed for cost-sensitive applications requiring enhanced analog features. It shares architectural similarities with other members like the AVR16EB20 and AVR32EB families but offers a distinct pin count and memory configuration. The series emphasizes energy efficiency and integrated analog front-end capabilities for modern embedded designs.

Replacement Considerations

Direct pin-compatible alternatives within the same family include the AVR16EB14-I/ST for industrial temperature ranges. For different packaging, check the tube version AVR16EB14-E/ST. Verify that substitute parts match the exact memory size and peripheral set to ensure software compatibility.
