AVR16EA48-I/PT

Overview

The AVR16EA48-I/PT is an 8-bit microcontroller from the AVR EA 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 industrial temperatures from -40°C to +85°C. Key peripherals include a 12-bit differential ADC with PGA, a 10-bit DAC, two analog comparators, three USARTs, SPI, TWI/I2C, and an event system for inter-peripheral signaling.

Feature Summary

• Features a flexible low-power architecture with an Event System for CPU-independent 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 across the AVR EA family due to full pin and feature compatibility.
• Integrates Configurable Custom Logic (CCL) with programmable Look-up Tables for custom digital logic implementation.

Applications

• Industrial control systems requiring robust analog signal processing
• Battery-powered devices utilizing low-power sleep modes
• Smart sensors with integrated event-driven logic
• General-purpose embedded applications needing versatile communication interfaces

Procurement Notes

Verify the specific ordering suffix against official Microchip documentation to confirm package type and temperature grade. Ensure the procurement channel sources genuine components to avoid counterfeit risks. Confirm that the requested variant matches the required industrial temperature range and pin count specifications before finalizing orders.

Selection Notes

Select this component when a balance of moderate memory capacity and advanced analog features is required. It is suitable for designs needing high-speed ADC conversion with programmable gain or precise timing via multiple timers. Consider the AVR EA family's upward compatibility if future scalability beyond 16 KB Flash might be necessary.

Part Context

This part belongs to the AVR16EA28/32/48 series within the broader AVR EA Family. It shares architectural similarities with higher-memory variants like the AVR32EA48 and AVR64EA48, allowing for potential code reuse. The 'I' suffix denotes the industrial temperature range, while 'PT' indicates the TQFP-48 package.

Replacement Considerations

AVR32EA48-I/PT and AVR64EA48-I/PT are vertically compatible upgrades within the same family. For downward migration, verify pin count constraints as smaller packages may offer fewer I/O options.
