概要

Description

The ATxmega128B1-AU is an AVR XMEGA B1 family microcontroller from Microchip (Atmel). It combines a high-performance 8/16-bit AVR core with: 128 KB Flash, 8 KB EEPROM, 8 KB RAM; runs up to about 32 MHz from a 1.6–3.6 V supply. Peripherals include multiple serial interfaces (USART, SPI, I2C/TWI), a 12-bit ADC with multiple channels, timers/counters with PWM, a DMA controller, and the XMEGA Event System for peripheral-to-peripheral routing. It also provides analog features (comparators), watchdog, brown-out detect, and other control-oriented peripherals. The “AU” suffix indicates the packaging type (typically a 64-pin TQFP). Supported development tools include Atmel Studio and the GCC-based toolchain (Microchip MPLAB X/AVR toolchain). Typical uses: embedded control, data acquisition, sensor interfacing, and motor control. For exact pinout and feature details, consult the official datasheet and product overview.

Features

Here are the key features of ATXMEGA128B1-AU (AVR XMEGA family):
- Architecture: AVR XMEGA 8/16-bit core with a rich event-driven design.
- Memory: 128 KB Flash program memory, 8 KB SRAM, 1 KB EEPROM (on-chip).
- Clock: Up to about 32 MHz operation with flexible clock sources.
- Peripherals: Multiple serial interfaces (generally 4 USARTs, SPI, TWI/I2C).
- Analog: 12-bit ADC with multiple input channels and internal references.
- Timers: Several 16-bit Timer/Counters with PWM capabilities.
- DMA/Event System: DMA controller and an event routing system for peripherals.
- Other: Hardware CRC engine; programmable I/O multiplexing for flexible peripheral mapping.
- Power: Low-power sleep modes, brown-out detector for surges/crashes.
- Debug/Package: On-chip debug support; packaged in AU (typical industrial-temp) variant suitable for -40 to 85°C environments.
Note: exact counts of I/O pins, ADC channels, and some peripherals can vary by package/revision; consult the datasheet for precise specs.
