FAQ

What is the maximum operating frequency and corresponding instruction cycle time?

The XC2267M72F80LAAKXUMA1 operates at a maximum CPU clock frequency of 80 MHz, delivering a 12.5 ns instruction cycle time for single-cycle execution of most arithmetic and logical operations. This timing is guaranteed under specified voltage (3.0–5.5 V) and temperature (−40 °C to +125 °C) conditions per datasheet Section 4.1.2.

Does this microcontroller support functional safety standards like ISO 26262?

Yes-XC2267M72F80LAAKXUMA1 includes hardware features required for ASIL-B compliance: ECC-protected Flash and SRAM, Memory Protection Unit (MPU), hardware CRC checker, lockstep-capable peripherals, and diagnostic libraries provided by Infineon's SafeTcore toolkit. Full qualification requires system-level integration and validation per ISO 26262 Part 6.

Can the on-chip ADCs perform simultaneous sampling across multiple channels?

Yes-the two integrated 10-bit ADCs can be synchronized to sample up to 16 channels concurrently with ≤1 μs conversion time per channel. Synchronization is controlled via the CAPCOM2 unit or CCU6x trigger signals, enabling precise phase-current acquisition in motor control applications without external timing circuitry.

Is external memory expansion supported, and what bus configurations are available?

Yes-the External Bus Controller supports up to 12 MB external address space with programmable bus characteristics. It allows multiplexed or demultiplexed 8-bit/16-bit data buses, selectable address bus width, and four chip-select signals for interfacing with SRAM, NOR Flash, or FPGA peripherals, as detailed in datasheet Section 3.2 and Table 4-32.
