MCU , 8BIT, ATMEGA, 20MHZ, DIP-40

The ATMEGA164A-PU is a high-performance 8-bit AVR RISC-based Microcontroller combines 16kB ISP flash memory with read-while-write capabilities, 512byte EEPROM, 1kB SRAM, 32 general purpose I/O lines, 32 general purpose working registers, a real time counter, three flexible timers/counters with compare modes and PWM, two USARTs, a byte oriented 2-wire serial interface, a 8-channel 10-bit A/D converter with optional differential input stage with programmable gain, programmable watchdog timer with internal oscillator, SPI serial port, a JTAG (IEEE 1149.1 compliant) test interface for on-chip debugging and programming and six software selectable power saving modes. The device operates between 1.8 to 5.5V. By executing powerful instructions in a single clock cycle, the device achieves throughputs approaching 1MIPS per MHz, balancing power consumption and processing speed.

• Advanced RISC architecture
• Power-on reset and programmable brown-out detection
• Internal calibrated RC oscillator
• External and internal interrupt sources
• Six sleep modes - idle, ADC noise reduction, power-save, power-down, standby and extended standby
• 131 Powerful instructions-most single clock cycle execution
• 32 x 8 General purpose working registers
• Fully static operation
• Up to 20MIPS throughput at 20MHz
• On-chip 2-cycle multiplier

• QTouch® library support
• JTAG (IEEE std. 1149.1 compliant) interface
• Programmable watchdog timer with separate on-chip oscillator
• On-chip analog comparator
• Interrupt and wake-up on pin change
