AVR16EB14T-I/ST

Overview

The AVR16EB14T-I/ST is an 8-bit microcontroller from Microchip Technology, based on the AVR core architecture. It features 16 KB of Read-While-Write (RWW) Flash program memory and 2 KB of data RAM. The device operates with a maximum clock frequency of 20 MHz and includes a 12-bit Analog-to-Digital Converter (ADC). It supports multiple communication interfaces including UART, SPI, and I2C. Additional peripherals consist of two Timer/Counter B (TCB) units, TCEX, TCF, and WEX modules. The component is housed in a TSSOP-14 package and functions within a supply voltage range of 1.8 V to 5.5 V.

Feature Summary

• Integrates 12-bit ADC with Programmable Gain Amplifier (PGA) for high-resolution analog signal acquisition.
• Features Read-While-Write (RWW) Flash technology allowing code execution while other memory sections are being modified.
• Includes dedicated hardware acceleration modules such as TCEX, TCF, and WEX for efficient peripheral management.

Applications

• Battery-powered sensor nodes requiring low power consumption and long data retention.
• Industrial control systems utilizing I2C and SPI communication protocols.
• Embedded applications needing precise analog input processing via the 12-bit ADC.

Procurement Notes

Verify the specific suffix 'I/ST' against official Microchip documentation to confirm the industrial temperature grade and tape-and-reel packaging format. Ensure compatibility with existing PCB footprints for the TSSOP-14 package. Cross-reference the datasheet revision date to validate pinout and electrical characteristics before finalizing procurement orders.

Selection Notes

Select this component when a balance of moderate memory capacity and rich peripheral integration is required in a compact 14-pin form factor. The inclusion of PGA-enhanced ADC makes it suitable for precision measurement tasks. Consider the RWW capability if background memory updates are necessary during active code execution without system interruption.

Part Context

This part belongs to the AVR EB series, which represents Microchip's newer generation of 8-bit microcontrollers. The EB series builds upon previous AVR architectures by integrating advanced analog peripherals and enhanced security features. It targets applications demanding higher performance and lower power consumption compared to legacy AVR devices, offering improved efficiency for modern embedded designs.

Replacement Considerations

Direct replacements within the same family include the AVR16EB14-M/ST or AVR16EB14-P/PT, depending on required package type and temperature range. Verify pin compatibility and software register mapping when substituting with other AVR EB series variants.
