The CPU executes instructions at one cycle per instruction for most operations, enabling deterministic real-time response in control loops.
Does the UPD78F1168AGF-GAS-AX include hardware debug support?
Yes, the UPD78F1168AGF-GAS-AX integrates a full IEEE 1149.1-compliant JTAG interface supporting boundary-scan testing, real-time trace, and on-chip debugging. It is fully compatible with Renesas QB-MINI2 and QB-78K0RKX3 emulators, enabling non-intrusive breakpoint setting, register inspection, and memory read/write during live execution of UPD78F1168AGF-GAS-AX firmware.
What is the Flash memory endurance specification for the UPD78F1168AGF-GAS-AX?
The UPD78F1168AGF-GAS-AX features 128 KB of SuperFlash® technology Flash memory rated for 100,000 write/erase cycles and guaranteed 10-year data retention at +85°C. This endurance level supports robust field firmware updates and parameter storage in industrial applications where reprogramming occurs infrequently but must remain reliable over decades of service life.
Can the UPD78F1168AGF-GAS-AX operate from a 3.3 V supply?
Yes, the UPD78F1168AGF-GAS-AX operates across a supply voltage range of 2.7 V to 5.5 V, making it fully compatible with standard 3.3 V logic systems. All I/O pins are 5 V tolerant when configured as inputs, and the internal voltage regulator supports stable core operation without external LDOs - simplifying power design for UPD78F1168AGF-GAS-AX-based boards.
How many ADC input channels does the UPD78F1168AGF-GAS-AX support?
The UPD78F1168AGF-GAS-AX integrates a 10-bit successive approximation ADC with 16 selectable input channels. These channels can be sourced from dedicated analog pins or shared with port pins (e.g., P00–P07, P10–P13), allowing flexible signal routing without additional multiplexers. The ADC supports scan mode, software trigger, and hardware trigger (e.g., from timer overflow) for synchronized sampling.
