AT90CAN64-15MZ 15MHz 128KB Flash CAN MCU 64-QFN
料号： AT90CAN64-15MZ ✓ 量产中AT90CAN64-15MZ 概述
An 8-bit AVR microcontroller is a compact embedded-processing device that combines a RISC processor core, program memory, data memory, peripherals, and I/O in one integrated circuit. The AT90CAN64 family belongs to the AVR embedded-controller hierarchy and is designed for control systems that need deterministic peripheral handling together with embedded serial communication.
Key features include 128 KB of ISP flash, 2 KB of EEPROM, 4 KB of SRAM, 53 general-purpose I/O lines, 32 general-purpose working registers, 133 powerful instructions, and a CAN controller identified as compliant with CAN V2.0A and V2.0B. The 15 MHz grade provides the device's stated clock-speed class, while the broad I/O count supports external sensors, actuators, communication transceivers, and human-interface circuitry.
The MCU architecture supports single-clock-cycle execution for many instructions and provides a close relationship between the AVR processor, the CAN peripheral, and embedded serial programming. This combination makes the device useful in industrial control, automotive communication modules, building equipment, instrumentation, and other CAN-connected embedded products where an 8-bit controller is sufficient.
Typical designs use the CAN controller with an external CAN transceiver, connect programming signals through ISP, and route the 53 I/O lines to application-specific interfaces. The 4.5 V to 5.5 V operating range is compatible with conventional 5 V embedded systems, although designers should confirm all timing, peripheral, and communication requirements against the manufacturer datasheet before production release.
A key design consideration is to preserve clean supply and ground distribution around the 64-QFN device. Place decoupling capacitance close to the supply pins, route high-current and switching nodes away from sensitive inputs, and validate CAN bus termination, transceiver standby behavior, and firmware timing in the complete system rather than relying only on the MCU block diagram.
This page combines manufacturer specifications, application guidance, verified comparison options, and practical design considerations to help engineers evaluate the AT90CAN64-15MZ for embedded CAN systems.

典型应用
AT90CAN64-15MZ 适用于 6 应用s: Industrial CAN Control, Automotive Communication Modules, Building and HVAC Equipment, CAN-Based Motor and Actuator Control, Instrumentation and Data Acquisition, IoT Gateways and Edge Nodes.
Industrial CAN Control
The AT90CAN64-15MZ fits industrial CAN control nodes that need local logic and network communication in one device. Its 128 KB ISP flash, 4 KB SRAM, 2 KB EEPROM, and 53 general-purpose I/O lines allow firmware to coordinate sensors, relay outputs, status indicators, and service interfaces. The integrated CAN controller supports CAN V2.0A/V2.0B protocols, while the 4.5 V to 5.5 V supply range supports conventional 5 V equipment. Place an external transceiver between the MCU and the bus, and validate termination, protection, timing, and grounding in the final network.
推荐
Automotive Communication Modules
The AT90CAN64-15MZ is suitable for CAN-connected modules that combine protocol handling with discrete control functions. Its AVR architecture, 53 I/O lines, and CAN controller allow a compact module to monitor inputs, report status, and drive outputs without adding a separate communication processor. The 15 MHz ordering grade and 4.5 V to 5.5 V operating range are useful for conventional automotive electronics architectures, but environmental qualification must be confirmed separately. The final design should include a qualified transceiver, transient protection, proper bus termination, and EMC validation.
推荐
Building and HVAC Equipment
The AT90CAN64-15MZ can serve as the central controller in HVAC, access-control, and building-automation equipment where several local signals must be coordinated over a CAN network. Its 128 KB of ISP flash supports protocol stacks and application firmware, while 4 KB of SRAM and 2 KB of EEPROM provide working and nonvolatile data space. The 53 I/O lines can interface with temperature sensors, switches, relays, displays, and actuators. Use the MCU for deterministic supervisory logic and select an external CAN transceiver with the required isolation, protection, and speed characteristics.
推荐
CAN-Based Motor and Actuator Control
The AT90CAN64-15MZ is appropriate for distributed motor, valve, and actuator nodes that accept commands over CAN and supervise local equipment. Its 53 I/O lines can connect position or limit switches, fault inputs, and drive-control signals, while the CAN controller handles remote command reception and status reporting. The 128 KB flash area provides room for control algorithms and diagnostics, and ISP supports in-circuit firmware updates. A practical implementation should separate noisy motor-drive paths from sensitive MCU traces, use suitable bus protection, and validate timing under worst-case bus loading.
推荐
Instrumentation and Data Acquisition
The AT90CAN64-15MZ supports compact instrumentation nodes that acquire local signals and forward measurements through a CAN network. Its 4 KB SRAM can hold working buffers, 2 KB of EEPROM can retain calibration or configuration data, and the 53 I/O lines simplify connection to sensors, switches, and status logic. The CAN controller adds efficient multi-node communication without requiring a separate communications processor. For accurate measurement systems, use appropriate analog front-end circuitry, isolate sensitive routes from digital switching, and confirm ADC, timer, and communication timing requirements in the manufacturer datasheet.
推荐
IoT Gateways and Edge Nodes
The AT90CAN64-15MZ can act as a compact edge node between CAN-connected equipment and a higher-level embedded controller. Firmware can validate local alarms, maintain operating state, and forward selected data while the 53 I/O lines handle discrete sensors and outputs. Its 128 KB ISP flash and 4 KB SRAM support moderate protocol and application workloads without a separate logic device. The 4.5 V to 5.5 V range integrates naturally with 5 V industrial subsystems, but a gateway design should use a regulated supply, add CAN bus protection, and verify bootloader and communications timing across worst-case operating conditions.

设计说明
Place the required decoupling capacitors close to the AT90CAN64-15MZ supply and ground pins, with the shortest practical return path to the ground plane. Keep the 64-QFN exposed pad and thermal-via arrangement consistent with the manufacturer's package drawing and assembly process. Route CAN transceiver, protection, and connector ground returns directly to the power-entry ground structure rather than through sensitive signal traces.
Keep the CAN TX and RX routing short and controlled, and place the external transceiver close to the bus connector where practical. Use protection components that are compatible with the transceiver's signal levels and CAN bit rate. Do not treat the MCU CAN pins as direct bus connections; the external transceiver provides the physical-layer drive, receive thresholds, isolation where selected, and bus protection interface.
Check the complete ordering code before substituting an AT90CAN64-family part. The family is hardware- and software-compatible according to Microchip, but speed grade, package suffix, supply range, temperature range, and qualification can differ. After replacement, revalidate startup timing, CAN bit timing, ISP programming, brownout behavior, and any firmware assumptions tied to the original clock configuration.
