Microchip (ATMEGA164PA-AU) 8 Bit MCU, 20 MHz, 16 KB, 44 Pins, TQFP

8 Bit MCU, AVR ATmega Family ATmega16X Series Microcontrollers, 20 MHz, 16 KB, 44 Pins, TQFP Product Overview The ATMEGA164PA-AU is a 8-bit high-performance picoPower AVR RISC-based Microcontroller combines 16kB ISP flash memory with read-while-write capabilities, 512B EEPROM, 1kB SRAM, 32 general purpose I/O lines, 32 general purpose working registers, a real time counter, three flexible timer/counters with compare modes and PWM, two USARTs, a byte oriented 2-wire serial interface, an 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 1 MIPS per MHz, balancing power consumption and processing speed. Advanced RISC architecture - On-chip 2-cycle multiplier High endurance, non-volatile memory segments QTouch® library support - Capacitive touch buttons, sliders and wheels JTAG (IEEE 1149.1 compliant) interface Peripheral features - Real time counter with separate oscillator Power-on reset (POR) 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 32 Programmable I/O lines Applications Industrial, Computers & Computer Peripherals Product Information Product Range: AVR ATmega Family ATmega16X Series Microcontrollers CPU Speed: 20MHz Program Memory Size: 16KB Operating Frequency Max: 20MHz RAM Memory Size: 1KB No. of Pins: 44Pins MCU Case Style: TQFP IC Case / Package: TQFP No. of I/O's: 32I/O's Embedded Interface Type: I2C, SPI, UART Interfaces: I2C, SPI, UART Supply Voltage Min: 1.8V Supply Voltage Max: 5.5V MCU Family: AVR ATmega MCU Series: ATmega16X Operating Temperature Min: -40°C Operating Temperature Max: 85°C IC Mounting: Surface Mount
