AT90CAN32-15AZ Visão geral
An 8-bit AVR microcontroller is a Harvard-architecture, single-cycle RISC processor optimized for deterministic embedded control. AVR MCUs belong to the broader category of microcontrollers (MCU) -> embedded processors -> semiconductors. The AT90CAN32-15AZ specifically belongs to the AT90CAN family, distinguished by an integrated CAN 2.0A/V2.0B (V2.0B compliant) controller that differentiates it from general-purpose AVR chips such as the ATmega series.
Key features of the AT90CAN32-15AZ include: 53 general-purpose I/O lines, 32 general-purpose working registers, an 8-channel 10-bit ADC, advanced communication peripherals (CAN, I2C, SPI, UART/USART), and standard AVR on-chip peripherals including Brown-out Detect/Reset, Power-on Reset, PWM, and a Watchdog Timer. The CAN controller provides hardware frame handling, reducing host CPU overhead in distributed control networks.
The AVR enhanced RISC architecture executes most instructions in a single clock cycle, delivering throughput approaching 1 MIPS per MHz. The automotive-grade designation (-AZ suffix) reflects qualification to AEC-Q100 standards, enabling deployment in powertrain, body, and chassis electronic control units. The wide supply voltage range allows direct operation from both 3.3V and 5V rails commonly found in automotive ECUs.
Typical applications include automotive body control modules, CAN-based sensor networks, industrial CAN nodes, vehicle lighting controllers, and HVAC actuators. The integrated CAN peripheral eliminates the need for an external CAN controller, reducing BOM cost and PCB area in space-constrained modules.
When designing with this device, ensure proper decoupling (100nF + 10uF) near the AVCC/AVSS analog supply pins, follow Microchip AN2461 for CAN bus termination, and verify the JTAG/debug pin assignments before laying out the PCB to avoid conflicts with general-purpose I/O.

Aplicações típicas
AT90CAN32-15AZ é adequado para 6 aplicaçãos: Automotive Body Control Module, Industrial CAN Node (CANopen / DeviceNet), Automotive Lighting Controller, HVAC Actuator Module, Battery Management CAN Slave, Agricultural Equipment CAN Node.
Automotive Body Control Module
The AT90CAN32-15AZ is well-suited for automotive body control modules because of its integrated CAN 2.0A/V2.0B controller, automotive AEC-Q100 qualification, and 32KB Flash that fits typical BCM firmware. With 53 GPIO lines and 16MHz throughput approaching 1 MIPS/MHz, it handles body-comfort tasks such as window lifters, mirror control, and central locking with deterministic latency. The 2.7V to 5.5V supply range allows power-rail sharing with neighbouring 5V loads.
Recomendado
Industrial CAN Node (CANopen / DeviceNet)
The AT90CAN32-15AZ provides a compact CANopen or DeviceNet slave node for industrial automation, where the on-chip CAN 2.0A/V2.0B controller reduces BOM cost by eliminating an external CAN IC. The 32KB Flash is sufficient for lightweight CANopen stack (CiA 301) implementations. Operating from 2.7V to 5.5V with -40 to +125C temperature range, it tolerates industrial cabinet thermal swings. The 8-channel 10-bit ADC handles typical analog sensor inputs.
Recomendado
Automotive Lighting Controller
The AT90CAN32-15AZ drives automotive exterior and interior lighting where CAN communication enables body-network integration. The on-chip PWM peripheral and 53 GPIO allow direct driving of LED matrices, headlamp assemblies, or sequential turn indicators without external PWM controllers. The AEC-Q100 grade qualification supports under-hood and exterior lighting requirements. The 32KB Flash accommodates DRL/AFS algorithms and CAN-based diagnostic routines.
Recomendado
HVAC Actuator Module
For HVAC actuators in vehicles, the AT90CAN32-15AZ provides LIN/CAN connectivity with sufficient Flash for airflow calibration curves. The integrated CAN controller interfaces with the body-network gateway, while the 10-bit ADC reads damper position feedback. The 53 GPIO handles multiple motor drivers and sensor inputs per damper assembly. The automotive temperature grade supports under-dash operating environments.
Recomendado
Battery Management CAN Slave
In distributed battery management systems, the AT90CAN32-15AZ acts as a cell-module slave node. The on-chip CAN controller reports per-module voltage, temperature, and balancing status to a master BMS over CAN. The 32KB Flash supports simple state-machine firmware for cell monitoring. The wide 2.7V-5.5V supply accepts common 5V cell-board rails. The 8-channel ADC reads cell voltages and thermistors directly.
Recomendado
Agricultural Equipment CAN Node
The AT90CAN32-15AZ provides rugged CAN connectivity in agricultural vehicles (tractors, harvesters) where environmental temperatures and supply voltages exceed consumer ranges. The -40C to +125C operating range and 2.7V-5.5V supply tolerate 12V/24V agricultural battery systems with simple regulators. The 32KB Flash supports ISOBUS-style message handling for implement communication, and the CAN 2.0B controller accepts 29-bit extended identifiers used in agricultural networks.

Notas de projeto
Decouple the AT90CAN32-15AZ VCC and AVCC pins with a 100nF ceramic capacitor placed within 5mm of each supply pin, and add a bulk 10uF tantalum or ceramic capacitor at the chip supply entry point. Per the manufacturer datasheet, the AVCC pin must be connected to VCC even if the ADC is unused - leave it floating can cause erratic behaviour on adjacent pins. Place a ferrite bead between VCC and AVCC if ADC noise exceeds 5ppm.
Place a 120-ohm CAN bus termination resistor at each end of the CAN bus segment, NOT at the AT90CAN32-15AZ side. Keep the CANTX/CANRX traces short and route them away from noisy traces such as PWM motor outputs. Use a 4-layer PCB with a dedicated ground plane underneath the part; the TQFP-64 thermal pad (or exposed pad) should connect to the ground plane via multiple vias for thermal dissipation.
Do not forget to add a pull-up resistor (typically 4.7k to 10k) on the RESET pin if not using a supervisor IC, otherwise spurious resets may occur during power-up. Configure the JTAGEN fuse before relying on the JTAG pins as GPIO, otherwise the debug interface may interfere with application code. Ensure the CAN bus topology does not exceed 1 Mbps at bus lengths above 40 meters without proper termination.
The CAN bus must use twisted-pair cabling with 120-ohm characteristic impedance. CANTX and CANRX traces on the PCB should be routed as a differential pair with 100-ohm differential impedance for lengths above 25mm. Per Microchip AN2461, keep stub lengths to the AT90CAN32-15AZ below 1/3 of the signal rise time to avoid reflections. Add common-mode chokes near the bus connector for EMI compliance.
