FAQ
What is the maximum operating frequency of the UPD78F1167AGF-GAS-AX?
The UPD78F1167AGF-GAS-AX operates at a maximum system clock frequency of 20 MHz, delivering a 50 ns instruction cycle time. This frequency is supported across the full industrial temperature range (−40 °C to +85 °C) and 4.5–5.5 V supply voltage. The UPD78F1167AGF-GAS-AX uses an on-chip oscillator circuit that eliminates the need for external crystals in many applications, though external clock sources are also supported via the X1/X2 pins.
Does the UPD78F1167AGF-GAS-AX include an integrated voltage regulator?
Yes, the UPD78F1167AGF-GAS-AX features an internal voltage regulator controlled by the REGC pin. When enabled, it generates a stable 3.3 V supply for the CPU core from the main 5 V VDD rail. An external 1 μF capacitor must be connected between REGC and EVSS for proper regulation. This function is documented in Renesas User's Manual U17854EJ9V0UD Section 2.2.15 and allows single-supply operation without external LDOs.
How many ADC channels does the UPD78F1167AGF-GAS-AX support?
The UPD78F1167AGF-GAS-AX integrates a 12-bit successive approximation ADC with 12 selectable input channels (AN0–AN11), mapped across ports P2 and P4. Conversion time is 1.1 μs per sample, and hardware triggers from timers or external events enable synchronized sampling. This ADC capability is confirmed in the electrical specifications table and pin function descriptions of Renesas User's Manual U17854EJ9V0UD.
Is the UPD78F1167AGF-GAS-AX pin-compatible with other 78K0R/KE3 devices?
The UPD78F1167AGF-GAS-AX shares the same 80-pin LQFP package and pin configuration with other members of the 78K0R/KE3 family, including UPD78F1142AGF-GAS-AX through UPD78F1146AGF-GAS-AX. Pin functions for ports, power, reset, and peripherals are consistent across these variants, enabling PCB reuse when migrating between memory sizes - provided firmware and peripheral usage align with the target device's resource allocation.
What debug tools are supported for the UPD78F1167AGF-GAS-AX?
The UPD78F1167AGF-GAS-AX supports on-chip debugging via Renesas QB-MINI2 and QB-78K0RKX3 emulators, using the built-in debug interface compliant with the 78K0R standard. No external JTAG adapter is required. Development is supported by RA78K0R assembler and CC78K0R C compiler toolchains, with full register visibility, breakpoint control, and real-time variable monitoring - all verified in Renesas User's Manual U17854EJ9V0UD and tool documentation.
