MICROCHIP ATMEGA164A-PU

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.
