AT40K40-2BQI

The AT40K40-2BQI is a CMOS-based integrated circuit (IC) developed by Atmel Corporation. It is a low-power, high-performance, single-chip microcontroller (MCU) designed for use in embedded control applications. The AT40K40-2BQI is based on the AT40K architecture, which combines a 32-bit RISC processor core with a wide range of peripherals and memory. The processor core is a 32-bit ARM Cortex-M4 with a maximum clock speed of up to 40 MHz. It has a 2Kbyte of internal SRAM and 128Kbyte of embedded Flash memory, making it ideal for low-power, high-performance embedded control applications.

The AT40K40-2BQI also features a wide range of peripherals, including a 10-bit Analog-to-Digital Converter (ADC), a 16-bit Timer/Counter, a 16-bit Pulse-Width Modulation (PWM) module, a UART, an I2C interface, and a SPI interface. It also includes an on-chip temperature sensor and a real-time clock (RTC). Additionally, the AT40K40-2BQI includes an on-chip debug interface, making it easy to debug and develop applications.

The AT40K40-2BQI is suitable for a wide range of embedded control applications, including industrial automation, motor control, sensing and monitoring, and consumer electronics. It is also well-suited for battery-powered applications, as it has a low power consumption of only 14 mW. The AT40K40-2BQI is available in a 48-pin LQFP package and is RoHS-compliant.
