The AT90CAN64-16AU is a member of the megaAVR family from Microchip Technology, designed for applications requiring CAN bus communication. It features an 8-bit AVR RISC core operating at up to 16 MHz, delivering throughputs approaching 1 MIPS per MHz. The device integrates 64KB of in-system programmable flash with read-while-write capability, 4KB SRAM, and 2KB EEPROM for data storage. The on-chip CAN controller is fully compliant with CAN specification V2.0A and V2.0B, supporting both standard and extended message frames with 15 message objects, each with its own identifier mask. The device also includes an 8-channel 10-bit ADC, two USARTs, an SPI port, and an I2C-compatible two-wire serial interface, making it a comprehensive solution for embedded control and communication applications.

The AT90CAN64-16AU operates around three primary subsystems: (1) The AVR CPU core executes instructions from the 64KB flash memory with a single-cycle execution model for most instructions, accessing 32 general-purpose working registers and peripheral control registers. (2) The CAN controller subsystem manages message transmission and reception according to the CAN 2.0A/2.0B protocol, handling bit timing, arbitration, error detection, and message filtering through 15 configurable message objects with individual identifier masks. (3) The peripheral subsystem provides timer/counter functions with PWM generation, analog-to-digital conversion through the 10-bit ADC with optional differential input, and serial communication via SPI, I2C, and dual USART channels. An internal oscillator, watchdog timer, and five power-saving modes (Idle, ADC Noise Reduction, Power-save, Power-down, and Standby) support flexible power management.
