FAQ
What is the maximum operating frequency of the UPD78F1501AGK-GAK-X3-AX?
The UPD78F1501AGK-GAK-X3-AX operates at a maximum system clock frequency of 20 MHz, achievable using an external crystal (1–20 MHz range) or the internal high-speed oscillator. This frequency governs instruction execution speed, peripheral timing, and ADC conversion rate - all verified in Section 1.1 and electrical specifications tables of the Rev.5.01 Hardware User's Manual.
Does the UPD78F1501AGK-GAK-X3-AX include an integrated voltage regulator?
Yes, the UPD78F1501AGK-GAK-X3-AX features an internal voltage regulator controlled via the REGC pin. When REGC is connected to VDD, the device generates a regulated 3.3 V supply (VCC33) for internal analog circuits and I/O buffers. A 1 µF ceramic capacitor must be placed between VCC33 and VSS per Renesas design guidelines in Section 2.2.23.
How many ADC channels does the UPD78F1501AGK-GAK-X3-AX support, and what is its resolution?
The UPD78F1501AGK-GAK-X3-AX integrates a 12-bit successive approximation ADC with 16 input channels (AN00–AN15), confirmed in Section 2.2.20 and Table 2.1 of the Hardware User's Manual. Its effective resolution maintains ±1 LSB integral nonlinearity across the full 0–VREF range, supporting precision sensor interfacing without external signal conditioning.
Is the UPD78F1501AGK-GAK-X3-AX pin-compatible with other members of the 78K0R/LF3 group?
Yes, the UPD78F1501AGK-GAK-X3-AX shares identical pin configuration and function mapping with other 78K0R/LF3 devices in LQFP-100 packaging, including UPD78F1500A and UPD78F1502A. Pin compatibility is explicitly documented in Section 1.3.1 (Pin Configuration) and Section 2.1.1 (Pin Function List) of the Rev.5.01 manual.
What debug tools are supported for the UPD78F1501AGK-GAK-X3-AX?
The UPD78F1501AGK-GAK-X3-AX supports on-chip debugging via Renesas' QB-MINI2 On-Chip Debug Emulator (document U18371E) and QB-78K0RLX3 In-Circuit Emulator (U19336E). These tools connect through the dedicated 4-pin debug interface (CLK, RST, TDI, TDO) and enable full breakpoint, watchpoint, and register inspection capabilities without requiring additional debug firmware.
