Microchip ATMEGA162V-8AU, 8bit AVR Microcontroller, Microcontrollers, 20MHz, 16 kB Flash, 44-Pin TQFP

The Microchip ATMEGA162 CMOS 8-bit microcontroller is based on the AVR enhanced RISC architecture. It features 16K bytes of In-System programmable flash with read while-write capabilities, 512 bytes EEPROM, 1K bytes SRAM, an external memory interface, 35 general purpose I/O lines, 32 general purpose working registers, a JTAG interface for Boundary-scan, On-chip debugging support and programming, four flexible Timer/Counters with compare modes, internal and external interrupts, two serial programmable USARTs, a programmable watchdog timer with internal oscillator, an SPI serial port, and five software selectable power saving modes. The Idle mode stops the CPU while allowing the SRAM, Timer/Counters, SPI port, and interrupt system to continue functioning. The Power-down mode saves the register contents but freezes the oscillator, disabling all other chip functions until the next interrupt or Hardware Reset. In Power-save mode, the asynchronous timer continues to run, allowing the user to maintain a timer base while the rest of the device is sleeping. In standby mode, the crystal/resonator oscillator is running while the rest of the device is sleeping.
