AVR16EB14-E/ST

Overview

The AVR16EB14-E/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 PGA, two analog comparators, and multiple timers including TCB, TCE, TCF, and RTC. The component is housed in a 14-pin TSSOP package and supports an extended industrial temperature range of -40°C to +125°C.

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 inter-peripheral signaling and Configurable Custom Logic (CCL) with Look-up Tables.
• Features a single-pin Unified Program and Debug Interface (UPDI) for programming and debugging.
• Includes advanced analog subsystems such as a 12-bit differential ADC with programmable gain amplifier and window compare functions.

Applications

• Low-power embedded control systems requiring extended temperature operation
• Applications utilizing event-driven peripheral communication
• Systems requiring precise analog signal acquisition with differential ADC inputs
• Industrial monitoring devices needing robust I/O and timer capabilities

Procurement Notes

Verify that the ordering suffix 'E' corresponds to the extended temperature range (-40°C to +125°C) and 'ST' indicates the TSSOP-14 package. Confirm the datasheet revision matches the required specifications, as preliminary documents may undergo updates. Ensure the source document explicitly lists this part number to validate availability and technical accuracy before procurement.

Selection Notes

Select this model when an extended operating temperature range is required compared to the industrial variant. The 14-pin form factor limits available I/O pins; verify that the 11 general-purpose I/O pins meet system requirements. Consider the 16 KB Flash size for application code constraints. Evaluate if the specific peripheral mix, including the 12-bit ADC and dual comparators, aligns with design needs.

Part Context

This component belongs to the AVR EB Family, which shares architectural similarities with other members like the AVR16EB20 or AVR32EB14. These devices offer horizontal and vertical migration paths. The AVR16EB14 specifically provides the lowest pin count in the 16 KB Flash segment of this family, making it suitable for compact designs.

Replacement Considerations

AVR16EB14-I/ST offers identical functionality with an industrial temperature range (-40°C to +85°C). For higher pin counts, consider AVR16EB20-E/REB or AVR16EB28-E/STX. For increased memory, the AVR32EB14 series provides 32 KB Flash while maintaining pin compatibility.
