FAQ

What is the maximum operating frequency and voltage range for the UPD78F1500AGK(R)-GAK-AX?

The UPD78F1500AGK(R)-GAK-AX operates at a maximum frequency of 20 MHz across its full supply voltage range of 2.7 V to 5.5 V. This allows consistent real-time performance in diverse industrial environments without voltage scaling. The device maintains full functionality-including ADC accuracy and timer resolution-across this entire range, and the UPD78F1500AGK(R)-GAK-AX datasheet specifies timing parameters under worst-case conditions at both extremes.

Does the UPD78F1500AGK(R)-GAK-AX support in-circuit debugging, and what tools are compatible?

Yes, the UPD78F1500AGK(R)-GAK-AX supports full-speed background debugging via its single-wire debug interface, compatible with Renesas QB-MINI2 and third-party SWD-compliant debuggers. The UPD78F1500AGK(R)-GAK-AX implements the RA78K0R debug specification, enabling breakpoints, live register inspection, and flash programming without halting peripheral operation. No external debug header is required-the interface uses dedicated pins P10 and P11.

How many ADC channels does the UPD78F1500AGK(R)-GAK-AX have, and what is their resolution?

The UPD78F1500AGK(R)-GAK-AX integrates a 10-bit successive-approximation ADC with 16 selectable input channels. It supports hardware-triggered scanning across all channels with programmable sample-and-hold timing, and includes built-in offset/gain calibration registers. The UPD78F1500AGK(R)-GAK-AX ADC achieves effective resolution of 9.5 ENOB at 100 kSPS with AVDD = 5.0 V and proper PCB layout.

What package type and pin count does the UPD78F1500AGK(R)-GAK-AX use?

The UPD78F1500AGK(R)-GAK-AX is supplied in a 64-pin LQFP package (10 mm × 10 mm, 0.5 mm pitch) with an exposed thermal pad. This JEDEC MS-026-compliant package provides mechanical stability and thermal dissipation suitable for industrial convection-cooled environments. The UPD78F1500AGK(R)-GAK-AX pinout is identical across all 78K0R/LF3 variants, enabling footprint reuse in scalable designs.

Is the UPD78F1500AGK(R)-GAK-AX qualified for industrial temperature operation?

Yes, the UPD78F1500AGK(R)-GAK-AX is rated for industrial temperature operation from −40°C to +85°C and is classified as "Standard" quality grade per Renesas documentation. It has been characterized and tested across this full range for all electrical parameters-including Flash write endurance, ADC linearity, and clock stability-and the UPD78F1500AGK(R)-GAK-AX meets all specifications without derating.
