Part Description

The AT90CAN32/64/128 is a low-power CMOS 8-bit microcontroller based on the AVR

enhanced RISC architecture. By executing powerful instructions in a single clock cycle, the

AT90CAN32/64/128 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 con-

ventional CISC microcontrollers.

The AT90CAN32/64/128 provides the following features: 32K/64K/128K bytes of In-System Pro-

grammable Flash with Read-While-Write capabilities, 1K/2K/4K bytes EEPROM, 2K/4K/4K

bytes SRAM, 53 general purpose I/O lines, 32 general purpose working registers, a CAN con-

troller, 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 differ-

ential 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 sav-

ing 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 main-

tain 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 On-

chip 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
