ATMEGA32M1-AU Datasheet PDF - Microchip

●The ATMEGA32M1-AU is a high-performance, low-power 8-bit AVR RISC-based Microcontroller combines 32kb ISP flash memory with read-while-write capabilities, 1kb EEPROM, 27 general purpose I/O lines, 32 general purpose working registers, one motor power stage controller, two flexible timer/counters with compare modes and PWM, UART with HW LIN, 11-channel 10-bit A/D converter with two differential programmable gain input stages, 10-bit D/A converter, programmable watchdog timer with internal individual oscillator, SPI serial port, on-chip debug system and four software selectable power saving modes. The device operates between 2.7 to 5.5V. By executing powerful instructions in a single clock cycle, the device achieves throughputs approaching 1 MIPS per MHz, balancing power consumption and processing speed.
