AT90CAN64-15AZ - 64KB 15MHz CAN AVR MCU | Microchip
Référence : AT90CAN64-15AZ ✓ ActifAT90CAN64-15AZ Présentation
An 8-bit AVR microcontroller is a reduced-instruction-computer device whose registers, arithmetic unit, and instruction set are optimized for efficient embedded control. The AVR architecture executes many instructions in a single clock cycle, while the AT90CAN64 family adds a CAN 2.0A/2.0B controller for communication between embedded nodes. This places the device within the hierarchy of semiconductor, microcontroller, embedded processor, and CAN-capable embedded controller.
Key device attributes include 64KB of ISP flash memory with read-while-write capability, 2KB of EEPROM, 4KB of SRAM, and an integrated CAN controller. The -15 speed designation corresponds to a 15 MHz operating frequency. The 64-pin TQFP package provides a conventional surface-mount footprint with gull-wing leads, while the integrated CAN controller reduces the need for a separate protocol controller in connected industrial, automotive, or equipment-control designs.
The AT90CAN64 family uses the AVR enhanced RISC architecture and provides general-purpose registers, timer resources, serial interfaces, and programmable I/O for embedded-control tasks. Its CAN controller supports CAN 2.0A and CAN 2.0B message formats, allowing the MCU to participate in standardized controller-area-network communication while local firmware handles acquisition, actuation, diagnostics, and system supervision.
Typical uses include industrial machine controllers, automotive body and accessory modules, CAN-based sensor gateways, industrial communication adapters, and compact embedded control boards. These applications benefit from the combination of local flash execution, EEPROM for persistent configuration, SRAM for working data, and integrated CAN handling. A separate CAN transceiver is still required to connect the MCU's logic-level CAN pins to a physical CAN bus.
Design around the 4.5 V to 5.5 V supply range, provide all specified decoupling and clock circuitry, and use the manufacturer pin-description table when assigning PCB tracks. Because the CAN interface operates through a bus transceiver, its pin voltage ratings, termination strategy, isolation requirements, and grounding scheme must be handled separately from the MCU supply design.
This product page combines the manufacturer's device information with practical package, power, communication, and selection guidance. It also distinguishes speed and temperature-grade alternatives while keeping every proposed replacement tied to the same 64-pin TQFP footprint.

Applications typiques
AT90CAN64-15AZ convient pour 6 applications: Industrial CAN Control Node, Automotive Body Control Module, CAN Sensor Gateway, CAN Communication Adapter, Machine Monitoring Controller, Low-Power Embedded Control Board.
Industrial CAN Control Node
The AT90CAN64-15AZ fits an industrial CAN node that performs local acquisition, control logic, diagnostics, and supervisory communication. Its 64KB ISP flash provides room for application firmware and boot code, while 4KB of SRAM supports active control buffers and 2KB of EEPROM preserves configuration values across power cycles. The integrated CAN 2.0A/2.0B controller reduces protocol overhead compared with a host-based implementation. At 15 MHz, the AVR core provides deterministic embedded processing, while the 64-pin TQFP package leaves ample board area for a transceiver, isolation, protection, and connectors.
Recommandé
Automotive Body Control Module
The AT90CAN64-15AZ can support distributed body-control functions that exchange switch, sensor, actuator, and diagnostic information over CAN. Its 64KB flash accommodates embedded control firmware, 4KB of SRAM handles active tasks, and 2KB of EEPROM supports persistent calibration or configuration. The integrated CAN controller is suitable for CAN 2.0A/2.0B message handling, while the 15 MHz AVR core manages real-time control work. Before automotive deployment, verify the exact AT90CAN64-15AZ temperature grade, qualification status, transient requirements, and CAN transceiver protection against the vehicle interface.
Recommandé
CAN Sensor Gateway
The AT90CAN64-15AZ is appropriate for a compact gateway that receives sensor information, applies filtering or scaling, and publishes results on a CAN network. Its 2KB of EEPROM can retain gateway configuration and calibration parameters, while 4KB of SRAM accommodates message buffers and working state. The 64KB flash capacity leaves space for protocol handling, diagnostics, and application firmware. The integrated CAN controller operates alongside the MCU peripherals, and the 64-pin TQFP package provides enough pins for sensing inputs, status indicators, and a separate communications transceiver in a maintainable surface-mount layout.
Recommandé
CAN Communication Adapter
A communication adapter based on the AT90CAN64-15AZ can bridge equipment controls, diagnostic tools, and peripheral subsystems over a CAN bus. The microcontroller's CAN 2.0A/2.0B controller provides a dedicated protocol engine, leaving the AVR core available for framing, filtering, status reporting, and configuration. Its 15 MHz clock supports responsive service handling, and 64KB of ISP flash permits field-updatable firmware. The 64-pin TQFP package also provides a practical route to separate CAN and logic-ground routing. Production designs still require an appropriate transceiver, bus protection, termination, and optional galvanic isolation.
Recommandé
Machine Monitoring Controller
The AT90CAN64-15AZ can supervise a connected machine by evaluating digital and analog inputs, coordinating actuators, tracking faults, and publishing operating state over CAN. Four kilobytes of SRAM provides workspace for timers, counters, and sampled data, while 2KB of EEPROM can store thresholds and setup parameters. The dedicated CAN controller allows the monitoring function to coexist with real-time embedded tasks without requiring a separate protocol IC. Its 15 MHz operation and 64-pin TQFP package are appropriate for industrial controller layouts that need communication, control I/O, and serviceable flash programming.
Recommandé
Low-Power Embedded Control Board
The AT90CAN64-15AZ supports compact embedded-control boards that combine local decision-making with CAN telemetry. The AVR architecture provides efficient register-based execution, 64KB of ISP flash for firmware, and 4KB of SRAM for active data, allowing the board to perform useful work between communication intervals. EEPROM can preserve calibration and operating parameters. A 15 MHz operating point simplifies timing analysis for many control loops, and the 64-pin TQFP package permits a conventional reflow assembly. Designers should use the manufacturer clock and decoupling guidance, implement reset and programming access, and evaluate sleep-mode behavior against the system's duty cycle.

Notes de conception
Design the AT90CAN64-15AZ supply for the documented 4.5 V to 5.5 V range. Place the manufacturer-recommended bypass capacitors close to the supply and ground pins, minimize loop area, and keep the CAN transceiver supply filtering separate enough to prevent switching or transient noise from coupling into the MCU rails. Do not power the device from an unregulated CAN-bus tap; provide a stable local source with appropriate startup and fault behavior.
Use the manufacturer pin-description table for every TQFP-64 assignment, especially pins carrying oscillator, programming, reset, or alternate peripheral functions. Keep the clock loop compact and route it away from CAN TX/RX and switching-power nodes. Preserve access to ISP programming and reset through the board layout, and provide test points that do not disturb high-impedance or timing-sensitive nets.
The MCU's integrated CAN controller does not directly drive a physical CAN bus. A compatible CAN transceiver is required for CANH and CANL, together with bus protection, termination, fault handling, and any required isolation. Also verify the exact operating-temperature suffix before assembly. Although some family listings describe a 16 MHz rating, the -15 ordering code is the 15 MHz part and should not be substituted without reviewing firmware timing.
Do not rely on a general AT90CAN128-family I/O count when allocating a 64-pin AT90CAN64 board. Peripheral multiplexing and package constraints determine which functions are simultaneously available. Review the AT90CAN64-specific pin table, alternate-function priorities, port-drive limits, and external interrupt requirements. Firmware should also include a safe state for reset and CAN bus-off conditions so the external transceiver and actuators remain controlled.
Informations de conformité
The lifecycle stage is listed as ACTIVE. The exact environmental, temperature-grade, and automotive qualification status must be confirmed for the exact ordering code before regulated deployment.
