Frequently Asked Questions

What is the maximum clock frequency of the COP8SAA728M8CHSXXX core, and how does it affect throughput?

The COP8SAA728M8CHSXXX core operates at up to 10 MHz, executing most instructions in a single clock cycle to deliver approximately 10 MIPS of throughput. This deterministic single-cycle execution is important for real-time control loops in motor drives and sensor polling applications. Combined with 512 bytes of on-chip RAM and 32 KB of ROM, the device handles moderate data-processing tasks without external memory, keeping the system cost low.

Which serial protocol does the COP8SAA728M8CHSXXX support, and what peripheral devices can it communicate with?

The COP8SAA728M8CHSXXX includes a MICROWIRE/PLUS serial interface, which is compatible with SPI-like 3-wire or 4-wire devices. This allows the MCU to communicate directly with serial EEPROMs, DACs, and ADC expanders at clock rates up to 4 MHz. For applications needing I2C or full-duplex UART communication, an additional software bit-bang implementation is feasible given the 10 MHz core speed.

How does the supply voltage range of COP8SAA728M8CHSXXX compare to competing 8-bit MCUs in battery applications?

The COP8SAA728M8CHSXXX operates from 2.5 V to 5.5 V, covering both 3.3 V regulated and 2-cell AA battery (approximately 3 V fresh, down to 2.5 V at end-of-life) power scenarios. This 2.5 V minimum is lower than older 8-bit families requiring 4.5 V minimum, allowing extended runtime on the same battery pack. Current consumption in active mode at 5 V is typically below 15 mA, making it suitable for coin-cell and alkaline battery designs.
