For engineers reviewing the UPD78F0547AGC(R)-GAD-AX datasheet, UPD78F0547AGC(R)-GAD-AX pinout, UPD78F0547AGC(R)-GAD-AX application, or UPD78F0547AGC(R)-GAD-AX equivalent, key selection criteria include Flash endurance (100,000 write/erase cycles), A/D conversion time (1.1 μs typical), and support for expanded-specification timing characteristics including enhanced X1 oscillator stability and reduced interrupt response latency for self-programming routines.

Technical Context

The UPD78F0547AGC(R)-GAD-AX implements the 78K0 CPU core with 16-bit address space, supporting both conventional- and expanded-specification modes. Its peripheral set includes three 16-bit timer arrays (each with capture/compare/PWM functions), a watchdog timer, and a real-time clock with calendar function.

It supports dual power domains (VDD/EVDD) for analog/digital separation, features dedicated AVREF/AVSS pins for high-precision A/D reference, and uses SuperFlash® technology licensed from SST for reliable flash programming with built-in erase/write verification logic.

Key Specifications

Pinout & Package

FAQ

What is the maximum operating frequency of the UPD78F0547AGC(R)-GAD-AX?

The UPD78F0547AGC(R)-GAD-AX operates at a maximum frequency of 20 MHz using the main system clock (X1 oscillator). This frequency is supported across its full operating voltage range (2.7 V to 5.5 V) and ambient temperature range (−40°C to +85°C), enabling deterministic real-time control with 1.1 μs instruction cycle time. The device also supports sub-clock mode (32.768 kHz) for low-power RTC operation independent of main clock domain.

Does the UPD78F0547AGC(R)-GAD-AX support in-system programming (ISP)?

Yes, the UPD78F0547AGC(R)-GAD-AX supports in-system programming via its on-chip debug interface and Renesas-provided self-programming library (U17516E). This allows firmware updates in the field without removing the device from the target board. Programming requires only the standard UART or CSI interface and adheres to the 100,000-cycle endurance specification for Flash memory, with verified data retention exceeding 100 years at 85°C.

How many A/D input channels does the UPD78F0547AGC(R)-GAD-AX have, and what is their resolution?

The UPD78F0547AGC(R)-GAD-AX integrates a 10-bit successive-approximation A/D converter with 24 configurable input channels (AN0–AN23). These channels are multiplexed across multiple I/O ports and support both single-ended and differential input configurations. Conversion time is guaranteed at 1.1 μs under expanded-specification conditions, and the A/D module includes dedicated AVREF and AVSS pins for improved noise immunity in mixed-signal applications.

Is the UPD78F0547AGC(R)-GAD-AX pin-compatible with other 78K0/KF2 microcontrollers?

The UPD78F0547AGC(R)-GAD-AX is pin-compatible with other 100-pin LQFP variants in the 78K0/KF2 family, including UPD78F0544AGC(R)-GAD-AX, UPD78F0545AGC(R)-GAD-AX, and UPD78F0546AGC(R)-GAD-AX. Pin mapping for power, reset, clocks, and peripheral signals remains consistent across these parts. However, differences in Flash size (96 KB to 128 KB) and RAM (6 KB to 8 KB) do not affect physical pinout, enabling flexible design reuse and migration paths.

What development tools are officially supported for the UPD78F0547AGC(R)-GAD-AX?

Renesas officially supports the QB-MINI2 on-chip debug emulator and the RA78K0 assembler (Ver. 4.01) for the UPD78F0547AGC(R)-GAD-AX. Additional validated tools include the CC78K0 C compiler (Ver. 4.00), ID78K0-QB integrated debugger, and PM+ Ver. 6.30 IDE. Flash programming is supported via PG-FP5 programmer or in-circuit via UART using the self-programming library documented in U17516E.
