FAQ
What is the maximum operating frequency of the SPC561MVR56D?
The SPC561MVR56D operates at a maximum CPU frequency of 64 MHz using its e200z0h Power Architecture® core. This clock speed is fully supported across the full industrial temperature range (-40°C to +125°C) and enables deterministic execution of complex engine control algorithms with sub-millisecond loop times. The SPC561MVR56D achieves this performance while maintaining strict power budget limits required for automotive ECU applications.
Does the SPC561MVR56D support AEC-Q100 qualification?
Yes, the SPC561MVR56D is qualified to AEC-Q100 Grade 1 standards, meaning it is rated for operation from -40°C to +125°C ambient temperature and has passed stress tests including HTOL, TC, and ESD. This qualification is documented in STMicroelectronics' official automotive reliability reports and is essential for use in engine bay applications. The SPC561MVR56D's qualification status is maintained through ST's certified automotive manufacturing flow.
How many CAN interfaces does the SPC561MVR56D include?
The SPC561MVR56D integrates three independent TouCAN 2.0B controller modules, each supporting bit rates up to 1 Mbps and full ISO 11898-1 compliance. These controllers operate concurrently and feature dedicated message buffers, FIFOs, and error counters - enabling seamless integration into multi-domain vehicle networks. All three CAN interfaces are accessible on the SPC561MVR56D's 144-pin LQFP package with dedicated TX/RX pins per channel.
What type of analog-to-digital converter is integrated into the SPC561MVR56D?
The SPC561MVR56D features two QADC64E modules, each providing 12-bit resolution, 16 input channels, and a minimum conversion time of 1.2 µs. These modules support simultaneous sampling, programmable gain, and hardware-triggered conversions synchronized to timer events - critical for high-fidelity sensor acquisition in engine knock detection and wideband lambda control. The QADC64E architecture is explicitly documented in the SPC561MVR56D reference manual and datasheet.
Is the SPC561MVR56D pin-compatible with other SPC56x series devices?
No, the SPC561MVR56D is not pin-compatible with other SPC56x series devices such as the SPC564A70L7 or SPC560B50L5. While sharing the same 144-pin LQFP package outline, pin functions differ significantly due to variations in peripheral integration, memory mapping, and power domain organization. Hardware migration between these devices requires PCB redesign. The SPC561MVR56D's pinout is unique to its specific feature set and must be verified against its official datasheet before layout.
