Part Desription
The AT90CAN32/64 is a low-power CMOS 8-bit microcontroller based on the AVR enhanced
RIS C architecture. By executing powerful instructions in a single clock cycle, the
AT90CAN32/64 achieves throughputs approaching 1 MIPS per MHz allowing the system
designer to optimize power consumption versus processing speed.
The AVR core combines a rich instruction set with 32 general purpose working registers. All 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 AT90CAN32/64 provides the following features: 32K/64K bytes of In-System Programmable
Flash with Read-While-Write capabilities, 1K/2K bytes EEPROM, 2K/4K bytes SRAM, 53 general purpose I/O lines, 32 general purpose working registers, a CAN controller, Real Time
Counter (RTC), four flexible Timer/Counters with compare modes and PWM, 2 USARTs, a byte
oriented Two-wire Serial Interface, an 8-channel 10-bit ADC with optional differential input stage
with programmable gain, a 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 five software selectable power saving modes.
The Idle mode stops the CPU while allowing the SRAM, Timer/Counters, SPI/CAN ports 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.
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,

resistors are activated. The Port A pins are tri-stated when a reset condition becomes active,
even if the clock is not running.

I/O-Ports paragraph of the complete Datasheet.
2.5.4

Port B output buffers have symmetrical drive characteristics with both high sink and source
capability. As inputs, Port B pins that are externally pulled low will source current if the pull-up
resistors are activated. The Port B pins are tri-stated when a reset condition becomes active,
even if the clock is not running.

I/O-Ports paragraph of the complete Datasheet.
2.5.10
RESET
Reset input. A low level on this pin for longer than the minimum pulse length will generate a
reset. The minimum pulse length is given in characteristics. Shorter pulses are not guaranteed
to generate a reset. The I/O ports of the AVR are immediately reset to their initial state even if
the clock is not running. The clock is needed to reset the rest of the AT90CAN32/64.

AVCC
AVCC is the supply voltage pin for the A/D Converter on Port F. It should be externally connected to VCC, even if the ADC is not used. If the ADC is used, it should be connected to VCC
through a low-pass filter.

Notes:
Comment
1. Address bits exceeding PCMSB (c.f complete Datasheet) are don’t care.
2. Address bits exceeding EEAMSB (c.f complete Datasheet) are don’t care.
3. For compatibility with future devices, reserved bits should be written to zero if accessed. Reserved I/O memory addresses
should never be written.
4. I/O Registers within the address range 0x00 - 0x1F 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.
5. Some of the status flags are cleared by writing a logical one to them. Note that, unlike most other AVRs, the CBI and SBI
instructions will only operate on the specified bit, and can therefore be used on registers containing such status flags. The
CBI and SBI instructions work with registers 0x00 to 0x1F only.
6. When using the I/O specific commands IN and OUT, the I/O addresses 0x00 - 0x3F must be used. When addressing I/O
Registers as data space using LD and ST instructions, 0x20 must be added to these addresses. The AT90CAN32/64 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 0x60 - 0xFF in SRAM, only the ST/STS/STD and LD/LDS/LDD
instructions can be used.
