TMS5704357BZWTQQ1 Technical Specifications

TMS5704357BZWTQQ1 Key Features

• Real-time dual-core ARM Cortex-R5F processing for deterministic control and higher throughput.
• Large integrated Flash (2 MB) and SRAM (256 KB) to host expanded firmware and multiple safety stacks, reducing external memory needs.
• Automotive-grade qualification (Q1) and extended temperature rating for reliable operation in demanding vehicle environments.
• Multiple CAN FD interfaces and on-chip peripherals to simplify integration with vehicle networks and sensors.

Typical Applications

• Powertrain and engine control systems that demand deterministic response times and robust isolation of safety functions to meet functional-safety targets in road vehicles.
• Safety-domain controllers where redundant processing and larger local memory enable over-the-air updates and diagnostic logging with minimal external components.
• Electric vehicle motor control and inverter management that need higher compute per channel for advanced torque and field-oriented control algorithms.
• Advanced driver assistance subsystems that require multiple CAN FD buses and real-time task scheduling for sensor fusion and actuator coordination.

TMS5704357BZWTQQ1 Advantages vs Typical Alternatives

The device offers stronger deterministic performance and more on-chip memory compared with many general-purpose microcontrollers, enabling larger safety stacks and faster control loops without adding external flash. Its dual-core Cortex-R5F architecture provides better isolation and redundancy than single-core MCUs, while automotive-grade (Q1) qualification and extended temperature rating give higher reliability for vehicle-level deployments. These factors yield lower system complexity and fewer discrete components versus typical alternative solutions.
