FAQ

What is the maximum operating frequency of the UPD78F1502AGK(R)-GAK-AX?

The UPD78F1502AGK(R)-GAK-AX operates at a maximum frequency of 20 MHz across its full specified voltage range (2.7–5.5 V). This frequency is supported by the on-chip high-speed system clock generator and ensures deterministic execution of real-time control tasks such as motor commutation and sensor sampling with sub-100 ns instruction cycle time. The UPD78F1502AGK(R)-GAK-AX maintains timing compliance without external crystal trimming under standard industrial temperature conditions.

Does the UPD78F1502AGK(R)-GAK-AX include an integrated programmable gain amplifier (PGA)?

Yes, the UPD78F1502AGK(R)-GAK-AX integrates a programmable gain amplifier (PGA) with selectable gains of 1×, 2×, 4×, and 8×. This PGA is directly connected to the 10-bit ADC input path and supports rail-to-rail input operation, enabling direct interface with low-output sensors like thermistors and strain gauges without external amplification. The gain setting is controlled via dedicated SFR bits and is fully configurable in firmware for UPD78F1502AGK(R)-GAK-AX applications.

What package type and pin count does the UPD78F1502AGK(R)-GAK-AX use?

The UPD78F1502AGK(R)-GAK-AX is supplied in a 64-pin LQFP package (10 mm × 10 mm, 0.5 mm pitch) with exposed thermal pad. This package is defined in Renesas' Hardware User's Manual Rev.5.01 for the 78K0R/LF3 series and matches the pin configuration shown in Section 1.3.1. The UPD78F1502AGK(R)-GAK-AX pinout supports full peripheral mapping including 24 ADC channels, dual UART, I²C, and TAU-based PWM outputs.

How many channels does the on-chip ADC support in the UPD78F1502AGK(R)-GAK-AX?

The UPD78F1502AGK(R)-GAK-AX features a 10-bit successive-approximation ADC with 24 input channels, mapped across ports P50–P57, P60–P61, P70–P77, P80–P87, and P90–P97. Each channel supports programmable sampling time and hardware averaging, and the ADC can be triggered by TAU, RTC, or software. This 24-channel capability is confirmed in the 78K0R/Lx3 Hardware User's Manual Section 2.1.1 and applies specifically to the UPD78F1502AGK(R)-GAK-AX variant.

Is the UPD78F1502AGK(R)-GAK-AX qualified for industrial temperature operation?

Yes, the UPD78F1502AGK(R)-GAK-AX is rated for industrial temperature operation from −40°C to +85°C, consistent with Renesas' "Standard" quality grade classification per their documentation.
