All the 32 registers are directly connected to the Arithmetic Logic Unit (ALU), allowing two independent registers to be accessed in one single instruction executed in one clock cycle. The resulting architecture is more code efficient while achieving throughputs up to ten times faster than conventional CISC microcontrollers. RESET XTAL1 XTAL2 5 7593GS–AVR–03/08 The AT90USB64/128 provides the following features: 64/128K bytes of In-System Programmable Flash with Read-While-Write capabilities, 2K/4K bytes EEPROM, 4K/8K bytes SRAM, 48 general purpose I/O lines, 32 general purpose working registers, Real Time Counter (RTC), four flexible Timer/Counters with compare modes and PWM, one USART, a byte oriented 2-wire Serial Interface, a 8-channels, 10-bit ADC with optional differential input stage with programmable gain, programmable Watchdog Timer with Internal Oscillator, an SPI serial port, IEEE std. 1149.1 compliant JTAG test interface, also used for accessing the On-chip Debug system and programming and six 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. The ADC Noise Reduction mode stops the CPU and all I/O modules except Asynchronous Timer and ADC, to minimize switching noise during ADC conversions. In Standby mode, the Crystal/Resonator Oscillator is running while the rest of the device is sleeping. This allows very fast start-up combined with low power consumption. In Extended Standby mode, both the main Oscillator and the Asynchronous Timer continue to run. The device is manufactured using Atmel’s high-density nonvolatile memory technology. The Onchip ISP Flash allows the program memory to be reprogrammed in-system through an SPI serial interface, by a conventional nonvolatile memory programmer, or by an On-chip Boot program running on the AVR core. The boot program can use any interface to download the application program in the application Flash memory. Software in the Boot Flash section will continue to run while the Application Flash section is updated, providing true Read-While-Write operation. By combining an 8-bit RISC CPU with In-System Self-Programmable Flash on a monolithic chip, the Atmel AT90USB64/128 is a powerful microcontroller that provides a highly flexible and cost effective solution to many embedded control applications. The AT90USB64/128 AVR is supported with a full suite of program and system development tools including: C compilers, macro assemblers, program debugger/simulators, in-circuit emulators, and evaluation kits. 2.2 2.2.1 Pin Descriptions VCC Digital supply voltage. 2.2.2 GND Ground. 2.2.3 Port A (PA7..PA0) Port A is an 8-bit bi-directional I/O port with internal pull-up resistors (selected for each bit).

For compatibility with future devices, reserved bits should be written to zero if accessed. Reserved I/O memory addresses should never be written. 2. I/O registers within the address range $00 - $1F are directly bit-accessible using the SBI and CBI instructions. In these registers, the value of single bits can be checked by using the SBIS and SBIC instructions. 3. Some of the status flags are cleared by writing a logical one to them. Note that the CBI and SBI instructions will operate on all bits in the I/O register, writing a one back into any flag read as set, thus clearing the flag. The CBI and SBI instructions work with registers 0x00 to 0x1F only. 4. When using the I/O specific commands IN and OUT, the I/O addresses $00 - $3F must be used. When addressing I/O registers as data space using LD and ST instructions, $20 must be added to these addresses. The AT90USB64/128 is a complex microcontroller with more peripheral units than can be supported within the 64 location reserved in Opcode for the IN and OUT instructions. For the Extended I/O space from $60 - $1FF in SRAM, only the ST/STS/STD and LD/LDS/LDD instructions can be used. 13 7593GS–AVR–03/08 5.

AT90USB647/6 Errata. • USB Eye Diagram violation in low-speed mode • Transient perturbation in USB suspend mode generates over consumption • Spike on TWI pins when TWI is enabled • High current consumption in sleep mode • Async timer interrupt wake up from sleep generate multiple interrupts 5. USB Eye Diagram violation in low-speed mode The low to high transition of D- violates the USB eye diagram specification when transmitting with low-speed signaling. Problem fix/workaround None. 4. Transient perturbation in USB suspend mode generates overconsumption In device mode and when the USB is suspended, transient perturbation received on the USB lines generates a wake up state. However the idle state following the perturbation does not set the SUSPI bit anymore. The internal USB engine remains in suspend mode but the USB differential receiver is still enabled and generates a typical 300µA extra-power consumption. Detection of the suspend state after the transient perturbation should be performed by software (instead of reading the SUSPI bit). Problem fix/workaround USB waiver allows bus powered devices to consume up to 2.5mA in suspend state. 3. Spike on TWI pins when TWI is enabled 100 ns negative spike occurs on SDA and SCL pins when TWI is enabled. Problem Fix/workaround No known workaround, enable AT90USB64/128 TWI first versus the others nodes of the TWI network. 2. High current consumption in sleep mode If a pending interrupt cannot wake the part up from the selected mode, the current consumption will increase during sleep when executing the SLEEP instruction directly after a SEI instruction. Problem Fix/workaround Before entering sleep, interrupts not used to wake up the part from the sleep mode should be disabled. 1. Asynchronous timer interrupt wake up from sleep generates multiple interrupts 27 7593GS–AVR–03/08 If the CPU core is in sleep and wakes-up from an asynchronous timer interrupt and then go back in sleep mode again it may wake up several times.
