Product Information

The ATmega32A is a low-power CMOS 8-bit microcontroller based on the AVR® enhanced RISC architecture. By executing powerful instructions in a single clock cycle, the ATmega32A achieves throughputs close to 1MIPS per MHz. This empowers system designer to optimize the device for power consumption versus processing speed.

ATMEGA32A Architecture

Discover the potential of the Atmel AVR microcontroller with its 131 powerful instructions executed in a single-clock cycle. Boasting 32 × 8 general-purpose working registers and fully static operation, it achieves up to 16 MIPS throughput at 16 MHz. The inclusion of on-chip 2-cycle multiplier and high-endurance non-volatile memory segments, including in-system self-programmable Flash, EEPROM, and internal SRAM, ensures reliability and flexibility in programming.

Efficient Programming and Debugging

Unlock the microcontroller’s full potential with its optional boot code section, in-system programming through on-chip boot program, and true read-while-write operation. Leverage the JTAG interface, boundary-scan capabilities, and on-chip debug support for seamless programming of Flash, EEPROM, fuses, and lock bits.

Sensory Capabilities

Experience the Atmel QTouch® library support, enabling capacitive touch buttons, sliders, and wheels with up to 64 sense channels. Enhance user interaction and interface design with this cutting-edge technology.

Peripheral Features

Explore the microcontroller’s peripheral features, including two 8-bit Timer/Counters, one 16-bit Timer/Counter, a real-time counter, and four PWM channels. With an 8-channel, 10-bit ADC supporting both single-ended and differential channels, the microcontroller ensures accurate data acquisition. Communicate seamlessly using the byte-oriented two-wire serial, programmable serial USART, and master/slave SPI serial interfaces.

Optimized Power Consumption

Take advantage of the microcontroller’s special features, such as power-on reset, programmable brown-out detection, internal calibrated RC oscillator, and six sleep modes catering to different power optimization needs. With 32 programmable I/O lines, the microcontroller is available in various packages, operating at voltages ranging from 2.7 to 5.5V and speed grades from 0 to 16 MHz.

Smart Power Management

Understand the power consumption nuances at different states: active (0.6mA), idle mode (0.2mA), and power-down mode (< 1μA). Witness a balance between performance and efficiency with the Atmel AVR 8-bit Microcontroller.
