FAQ

What is the maximum operating frequency of the UPD78F1501AGK-GAK-E3-AX?

The UPD78F1501AGK-GAK-E3-AX supports a maximum CPU clock frequency of 20 MHz when powered within its specified 2.7–5.5 V supply range. This frequency is achieved using the on-chip high-speed oscillator or an external crystal up to 20 MHz, and is confirmed in Section 1.1 (Features) and Section 3.1.1 (Internal program memory space) of the 78K0R/Lx3 Hardware User's Manual Rev.5.01.

Does the UPD78F1501AGK-GAK-E3-AX include an on-chip voltage regulator?

Yes, the UPD78F1501AGK-GAK-E3-AX includes an on-chip voltage regulator controlled by the REGC pin. When VDD is ≥ 4.0 V, enabling REGC allows the device to generate a stable 3.3 V internal supply for core logic - eliminating the need for an external LDO in many 5 V system designs, as documented in Section 2.2.23 and Section 1.1 of the 78K0R/Lx3 Hardware User's Manual.

How many ADC channels does the UPD78F1501AGK-GAK-E3-AX support, and what is the resolution?

The UPD78F1501AGK-GAK-E3-AX supports 24 analog input channels with 10-bit resolution. The ADC features an internal reference voltage and programmable sampling time, enabling accurate sensor measurements across industrial temperature ranges. This specification is explicitly listed in Section 1.1 (Features) and detailed in Section 2.2.20 of the 78K0R/Lx3 Hardware User's Manual Rev.5.01.

What communication interfaces are integrated into the UPD78F1501AGK-GAK-E3-AX?

The UPD78F1501AGK-GAK-E3-AX integrates I²C, UART (2 channels), and CSI (2 channels) interfaces. These peripherals support standard serial communication protocols for sensor interfacing, host connectivity, and display control. Their pin assignments and functional modes are fully described in Sections 2.1.1 (Pin Function List) and 4.1 (Port Functions) of the official Renesas hardware manual.

Is the UPD78F1501AGK-GAK-E3-AX pin-compatible with other members of the 78K0R/LF3 family?

Yes, the UPD78F1501AGK-GAK-E3-AX shares identical pin configuration and function mapping with other 78K0R/LF3 devices such as μPD78F1500A and μPD78F1502A in the 64-pin LQFP package, as confirmed in Section 1.3.1 (78K0R/LF3) and Section 2.1.1 of the 78K0R/Lx3 Hardware User's Manual Rev.5.01 - enabling drop-in replacement within the same package variant.
