Technical Context

The UPD78F0547AGK(R)-GAK-E1-AX implements the 78K0S CPU core with 16-bit address space and 8-bit data path, executing instructions in one to four CPU cycles. It integrates a 16-bit multifunction timer (TM00–TM03) with input capture, output compare, and PWM generation, plus a 16-bit watchdog timer with independent clock source.

Peripheral resources include a UART (ch0/ch1), CSI (ch0/ch1), I²C-compatible serial interface (SI), 10-bit A/D converter with programmable sample-and-hold timing, and a voltage regulator controller (REGC) supporting low-power modes. All peripherals are clocked from selectable internal or external sources with configurable prescalers.

FAQ

What is the maximum operating frequency of the UPD78F0547AGK(R)-GAK-E1-AX?

The UPD78F0547AGK(R)-GAK-E1-AX supports a maximum CPU clock frequency of 20 MHz. This can be achieved using either the internal high-speed oscillator (HOC) or an external crystal/resonator connected to the X1/X2 pins. The device maintains full peripheral functionality-including A/D conversion, UART, and timer operations-at this frequency, with timing parameters fully specified in the hardware manual Rev.4.01.

Does the UPD78F0547AGK(R)-GAK-E1-AX support in-system programming?

Yes, the UPD78F0547AGK(R)-GAK-E1-AX supports in-system programming via its on-chip Flash memory and included self-programming library. The UPD78F0547AGK(R)-GAK-E1-AX allows firmware updates in the target application using standard I/O pins and internal routines-no external programmer required. This capability is validated in Application Note U17516E and requires proper initialization of the Flash control registers before write/erase operations.

What package type and pin count does the UPD78F0547AGK(R)-GAK-E1-AX use?

The UPD78F0547AGK(R)-GAK-E1-AX uses a 100-pin LQFP package (14 mm × 14 mm, 0.5 mm pitch) with exposed thermal pad. This matches the standard 78K0/KF2 mechanical outline defined in Renesas documentation. Pin assignments-including VDD/EVDD separation, dedicated REGC control, and SWD debug interface-are fixed per the hardware manual and verified in the pin function list section 2.1.5.

How many A/D input channels does the UPD78F0547AGK(R)-GAK-E1-AX support?

The UPD78F0547AGK(R)-GAK-E1-AX supports 16 analog input channels for its 10-bit successive-approximation A/D converter. These channels map to dedicated pins across ports P0 through P14, with flexible software-selectable channel sequencing and scan mode. Conversion time is guaranteed at 1.2 μs minimum under 20 MHz CPU clock conditions, as confirmed in the electrical characteristics table of the hardware manual.

Is the UPD78F0547AGK(R)-GAK-E1-AX qualified for automotive applications?

No, the UPD78F0547AGK(R)-GAK-E1-AX is classified as a Standard quality grade device per Renesas' quality grading system and is intended for industrial, office, and consumer equipment-not automotive or safety-critical systems. Its qualification excludes AEC-Q100 testing and automotive temperature range (-40°C to +125°C); the specified operating range is -20°C to +75°C ambient, as documented in Section 7 of the User's Manual Rev.4.01.
