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.Up to 16 MIPS throughput at 16 MHz Programming lock for software security On-chip analog comparator Power-on reset and programmable brown-out detection Two 8-bit Timer/Counters with separate prescalers and compare modes Two 16-bit Timer/Counters with separate prescalers, compare modes, and capture modes Internal calibrated RC oscillator External and internal interrupt sources More information:  | | Family Name: | Microcontrollers | Package Type: | TQFP | Mounting Type: | Surface Mount | Pin Count: | 44 | Device Core: | AVR | Data Bus Width: | 8bit | Program Memory Size: | 16 kB | Maximum Frequency: | 20MHz | RAM Size: | 1 kB | USB Channels: | 0 | Number of PWM Units: | 1 | Number of SPI Channels: | 1 | Number of CAN Channels: | 0 | Number of I2C Channels: | 0 | Number of UART Channels: | 0 |
