FAQ

What is the maximum operating frequency of the UPD78F1518AGF(S)-GAT-AX?

The UPD78F1518AGF(S)-GAT-AX operates at a maximum CPU clock frequency of 20 MHz with an internal high-speed oscillator option. Its peripheral clocks-including CAN, ADC, and TAU-are derived from this base clock with programmable prescalers, ensuring synchronized timing across all subsystems without external clock tree complexity. The UPD78F1518AGF(S)-GAT-AX maintains full specification compliance across its rated industrial temperature range (−40°C to +85°C) at this frequency.

Does the UPD78F1518AGF(S)-GAT-AX support CAN FD?

No, the UPD78F1518AGF(S)-GAT-AX implements CAN 2.0B only, supporting standard and extended frame formats at bit rates up to 1 Mbps. It does not include CAN FD features such as flexible data-rate switching or enhanced payload length. For CAN FD capability, Renesas offers later-generation RL78/F1x or RA6Mx devices. The UPD78F1518AGF(S)-GAT-AX remains fully compliant with ISO 11898-1:2003 for classical CAN networks used in industrial automation.

How many ADC input channels does the UPD78F1518AGF(S)-GAT-AX provide?

The UPD78F1518AGF(S)-GAT-AX integrates a 12-bit successive approximation ADC with 24 selectable input channels, mapped across ports P2, P3, P4, and P5. These include dedicated analog inputs and multiplexed I/O pins with internal sample-and-hold. The UPD78F1518AGF(S)-GAT-AX supports simultaneous sampling of up to two channels using dual ADC triggers, enabling accurate phase current measurement in motor control applications.

Is the UPD78F1518AGF(S)-GAT-AX pin-compatible with other 78K0R/LH3 devices?

Yes, the UPD78F1518AGF(S)-GAT-AX shares identical pinout and package (100-pin LQFP) with other 78K0R/LH3 members including μPD78F1506A, 78F1507A, and 78F1516A. This allows direct substitution within the same footprint when upgrading Flash/RAM capacity or peripheral configuration-provided external circuitry matches the enabled features (e.g., CAN transceivers, ADC references). The UPD78F1518AGF(S)-GAT-AX retains full electrical and mechanical compatibility across the LH3 group.

What debug interface does the UPD78F1518AGF(S)-GAT-AX support?

The UPD78F1518AGF(S)-GAT-AX supports Renesas' on-chip debug interface compliant with IEEE 1149.1 (JTAG) and SWD protocols, enabling full-featured debugging via QB-MINI2 or QB-78K0RLX3 emulators. It provides real-time trace, hardware breakpoints, and memory access without halting CPU execution. The UPD78F1518AGF(S)-GAT-AX requires no external debug header-debug signals share dedicated pins (TCK, TMS, TDI, TDO, TRST) routed internally to the debug module.
