7593JS–AVR–03/09
The AVR core combines a rich instruction set with 32 general purpose working registers. 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.
The ATmega32U6/AT90USB64/128 provides the following features: 32/64/128K bytes of InSystem Programmable Flash with Read-While-Write capabilities, 1K/2K/4K bytes EEPROM,
2.5K/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 Powersave 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 ATmega32U6/AT90USB64/128 is a powerful microcontroller that provides a highly
flexible and cost effective solution to many embedded control applications.
The ATmega32U6/AT90USB64/128 AVR is supported with a full suite of program and system
development tools including: C compilers, macro assemblers, program debugger/simulators, incircuit emulators, and evaluation kits.

3. About Code Examples
This documentation contains simple code examples that briefly show how to use various parts of
the device. Be aware that not all C compiler vendors include bit definitions in the header files
and interrupt handling in C is compiler dependent. Please confirm with the C compiler documentation for more details.
These code examples assume that the part specific header file is included before compilation.
For I/O registers located in extended I/O map, "IN", "OUT", "SBIS", "SBIC", "CBI", and "SBI"
instructions must be replaced with instructions that allow access to extended I/O. Typically
"LDS" and "STS" combined with "SBRS", "SBRC", "SBR", and "CBR".

Note:
Page
1. 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
ATmega32U6/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.

• Incorrect CPU behavior for VBUSTI and IDTI interrupts routines
• USB Eye Diagram violation in low-speed mode
• Transient perturbation in USB suspend mode generates over consumption
• VBUS Session valid threshold voltage
• USB signal rate
• VBUS residual level
• Spike on TWI pins when TWI is enabled
• High current consumption in sleep mode
• Async timer interrupt wake up from sleep generate multiple interrupts
9.
Incorrect CPU behavior for VBUSTI and IDTI interrupts routines
The CPU core may incorrectly execute the interrupt vector related to the VBUSTI and IDTI
interrupt flags.
Problem fix/workaround
Do not enable these interrupts, firmware must process these USB events by polling VBUSTI
and IDTI flags.
8.
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.
7.
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
26
ATmega32U6/AT90USB64/128
7593JS–AVR–03/09
ATmega32U6/AT90USB64/128
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.
6.
VBUS Session valid threshold voltage
The VSession valid threshold voltage is internally connected to VBus_Valid (4.4V approx.).
That causes the device to attach to the bus only when Vbus is greater than VBusValid
instead of V_Session Valid. Thus if VBUS is lower than 4.4V, the device is detached.
Problem fix/workaround
According to the USB power drop budget, this may require connecting the device toa root
hub or a self-powered hub.
5.
UBS signal rate
The average USB signal rate may sometime be measured out of the USB specifications
(12MHz ±30kHz) with short frames. When measured on a long period, the average signal
rate value complies with the specifications. This bit rate deviation does not generates communication or functional errors.
Problem fix/workaround
None.
4.
VBUS residual level
In USB device and host mode, once a 5V level has been detected to the VBUS pad, a residual level (about 3V) can be measured on the VBUS pin.
Problem fix/workaround
None.
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 ATmega32U6/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
7593JS–AVR–03/09
If the CPU core is in sleep and wakes-up from an asynchronous timer interrupt and then go
back in sleep again it may wake up multiple times.
Problem Fix/workaround
A software workaround is to wait with performing the sleep instruction until
TCNT2>OCR2+1.

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. 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 ATmega32U6/AT90USB64/128 TWI first, before 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 sleep mode should be
disabled.
1. Asynchronous timer interrupt wake up from sleep generates multiple interrupts
If the CPU core is in sleep mode and wakes-up from an asynchronous timer interrupt and
then goes back into sleep mode, it may wake up multiple times.
Problem Fix/workaround
31
7593JS–AVR–03/09
A software workaround is to wait beforeperforming the sleep instruction: until
TCNT2>OCR2+1.
9. AT90USB647/6 Errata.
• Incorrect interrupt routine exection for VBUSTI, IDTI interrupts flags
• 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
6.
Incorrect CPU behavior for VBUSTI and IDTI interrupts routines
The CPU core may incorrectly execute the interrupt vector related to the VBUSTI and IDTI
interrupt flags.
Problem fix/workaround
Do not enable these interrupts, firmware must process these USB events by polling VBUSTI
and IDTI flags.
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 ATmega32U6/AT90USB64/128 TWI first versus the others
nodes of the TWI network.
2. High current consumption in sleep mode

1. Asynchronous timer interrupt wake up from sleep generates multiple interrupts
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.
Problem Fix/workaround
A software workaround is to wait with performing the sleep instruction until
TCNT2>OCR2+1.
