AVR16EB14-I/ST

Overview

The AVR16EB14-I/ST is an 8-bit microcontroller from the AVR EB Family, utilizing the AVR CPU with a hardware multiplier. It features 16 KB of Flash memory with read-while-write capability, 2 KB of SRAM, and 512 bytes of EEPROM. The device operates at clock speeds up to 20 MHz within a supply voltage range of 1.8 V to 5.5 V. It includes a 12-bit differential ADC with a programmable gain amplifier, two analog comparators, and multiple digital peripherals such as USART, SPI, and TWI/I2C interfaces.

Feature Summary

• Supports vertical migration without code modification across the AVR EB family due to full pin and feature compatibility.
• Integrates an Event System for CPU-independent and predictable inter-peripheral signaling.
• Includes Configurable Custom Logic (CCL) with programmable Look-up Tables for flexible logic implementation.
• Features automated Cyclic Redundancy Check (CRC) scanning for Flash program memory integrity verification.

Applications

• Low-power embedded control systems requiring in-system reprogrammability
• Signal measurement applications utilizing input capture capabilities
• Industrial monitoring using differential ADC and analog comparators
• Communication interfaces via USART, SPI, and TWI/I2C

Procurement Notes

Verify the specific ordering suffix against official Microchip documentation to confirm package style and temperature range. The 'I' suffix indicates industrial temperature operation, while 'ST' denotes the TSSOP14 package. Ensure that any additional characters correspond strictly to carrier types defined in the datasheet to avoid functional mismatches.

Selection Notes

Select this component when a compact 14-pin solution is required alongside standard AVR EB family features. It provides sufficient memory and peripheral density for basic control tasks while maintaining compatibility with larger pin-count variants for future design scaling. Consider the 12-bit ADC resolution and event system requirements for signal processing needs.

Part Context

This part belongs to the AVR EB Family, which shares a common architecture and instruction set. Devices in this family offer horizontal migration options by reducing pin counts and associated features. The AVR16EB14 represents the entry-level pin count variant within the 16 KB Flash memory segment of the series.
