FAQ

What is the maximum operating frequency of the UPD78F1828AGAA-GAM-G?

The UPD78F1828AGAA-GAM-G supports a maximum CPU operating frequency of 20 MHz when using the on-chip PLL. Without PLL, the maximum frequency is 16 MHz using the main system clock. This timing performance enables sub-microsecond interrupt latency and deterministic execution of real-time control loops in applications such as motor drive and sensor acquisition.

Does the UPD78F1828AGAA-GAM-G include an integrated CAN transceiver?

No, the UPD78F1828AGAA-GAM-G integrates a CAN 2.0B protocol controller but requires an external CAN transceiver (e.g., SN65HVD230 or TJA1042) for physical layer signaling. The CANTX0 and CANRX0 pins provide differential logic-level outputs/inputs compatible with industry-standard transceivers, enabling flexible bus termination and ESD protection design.

What is the Flash memory endurance specification for the UPD78F1828AGAA-GAM-G?

The UPD78F1828AGAA-GAM-G specifies 100,000 write/erase cycles for its 256 KB on-chip Flash memory. This endurance rating applies under standard operating conditions (−40°C to +85°C) and supports field firmware updates via CAN or UART-based bootloader implementations without premature wear-out concerns in typical industrial deployment scenarios.

How many analog input channels does the UPD78F1828AGAA-GAM-G support?

The UPD78F1828AGAA-GAM-G features a 12-bit successive-approximation ADC with 16 selectable analog input channels. These channels are mapped across multiple I/O ports (P10–P17, P30–P32, P40–P47, etc.) and support simultaneous sampling triggers from timers or external events, enabling synchronized current/voltage measurement in motor control applications.

Is the UPD78F1828AGAA-GAM-G pin-compatible with other 78K0R/FC3 devices?

Yes, the UPD78F1828AGAA-GAM-G shares the same 48-pin LQFP package and pin assignment with other 78K0R/FC3 48-pin variants (e.g., UPD78F1826AGAA-GAM-G, UPD78F1827AGAA-GAM-G, UPD78F1829AGAA-GAM-G). This allows drop-in replacement within the FC3 family for memory or peripheral scaling, provided software configuration matches the selected variant's resource map.
