ATXMEGA128B1-CU Description

Short technical summary and product information.

The ATXMEGA128B1-CU is a high-performance, low-power AVR XMEGA 8/16-bit microcontroller from Microchip Technology. It features 128KB of in-system self-programmable flash memory, 8KB of internal SRAM, and 2KB of EEPROM. The device operates at up to 32 MHz with a supply voltage range of 1.6V to 3.6V, making it suitable for battery-powered and low-power applications.

 

This microcontroller integrates a rich set of peripherals including a two-channel DMA controller, four-channel event system, three 16-bit timer/counters, a USB 2.0 full-speed device interface, two USARTs with IrDA support, SPI, I2C, and a 16-channel 12-bit ADC. It also includes a liquid crystal display (LCD) controller capable of driving up to 4x40 segments, an AES and DES crypto engine, and a CRC generator.

 

The ATXMEGA128B1-CU comes in a 100-CBGA (9x9) surface mount package and is rated for an operating temperature range of -40°C to 85°C. It supports JTAG and PDI programming/debug interfaces and includes features such as brown-out detection, power-on reset, and programmable watchdog timer.
