1.1 AVR16EB32 Key Features

The AVR® EB family integrates real-time control and drive functionality into the AVR’s functionality.

Featuring the latest Core Independent Peripherals (CIPs), these microcontrollers (MCUs) excel as

stand-alone processors that will be valuable additions to any modern embedded design.

• Up to 32 KB in-system-programmable Flash memory with a true read-while-write operation

• Programming and Debug Interface Disable (PDID) Security Functionality

• One 16-bit Timer/Counter type E (TCE) with four compare channels for PWM generation and

Waveform Extension (WEX)

• One 24-bit Timer/Counter type F (TCF) for frequency generation

• One 16-bit Real-Time Counter (RTC) that can run from an external crystal or internal oscillator

• One 12-bit, 300 ksps, differential Analog-to-Digital Converter (ADC) with a programmable gain

amplifier (PGA)

• Two Analog Comparators (ACs) with window compare functions

• Configurable Custom Logic (CCL) with up to four programmable Look-up Tables (LUTs)

• Event System for CPU-independent and predictable inter-peripheral signaling

• Configurable, internally generated reference voltage
