Overview
The AVR64EA48-E/PT is an 8-bit AVR microcontroller featuring a CPU with hardware multiplier running at up to 20 MHz. It includes 64 KB of Flash memory, 6 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 an industrial temperature range of -40°C to +85°C. It provides 42 programmable I/O pins in a TQFP-48 package.
Feature Summary
- Features a flexible low-power architecture with Event System and accurate analog subsystems
- Includes a 12-bit differential ADC with Programmable Gain Amplifier (PGA) for precise signal measurement
- Supports simultaneous host and client operation on the TWI/I2C interface
- Offers Configurable Custom Logic (CCL) with multiple Look-up Tables for independent peripheral signaling
Applications
- Real-time control systems
- Sensor nodes
- Secondary safety monitoring equipment
- Closed-loop control system design
Procurement Notes
Verify the ordering suffix 'E' confirms the extended temperature rating of -40°C to +125°C if required, though datasheet specifications list this specific part under industrial ranges. Confirm the '/PT' suffix indicates the TQFP-48 package type. Ensure compatibility with existing designs by checking pin and feature compatibility within the AVR EA family for vertical migration without code modification.
Selection Notes
Select this component when high-speed integrated analog peripherals are needed alongside low-power performance. The inclusion of a hardware multiplier and single-cycle I/O register access supports efficient real-time processing. Consider the 48-pin form factor for applications requiring extensive GPIO availability and multiple communication interfaces like USART, SPI, and TWI.
Part Context
This device belongs to the AVR® EA Family, which utilizes the latest Microchip technologies for flexible and low-power architectures. The family allows for vertical migration without code modifications across different pin counts and memory sizes. The AVR64EA48 variant specifically offers the highest pin count and memory capacity within the 64 KB Flash segment of the series.
