The UPD78F1156AGK-GAK-AX supports a maximum system clock frequency of 20 MHz, achieved using an external crystal oscillator or ceramic resonator connected to the X1/X2 pins. This frequency enables a 50 ns instruction cycle time for time-critical control tasks, and the device maintains full functionality across its specified −40°C to +85°C operating temperature range at this speed.
Does the UPD78F1156AGK-GAK-AX include hardware debugging support?
Yes, the UPD78F1156AGK-GAK-AX features a dedicated on-chip debug interface compatible with Renesas' QB-MINI2 emulator and RA78K0R development environment. It supports single-step execution, breakpoint setting, register inspection, and Flash memory programming through a 2-pin SWD (Serial Wire Debug) connection, eliminating the need for additional debug circuitry on the target board.
What type of Flash memory technology is used in the UPD78F1156AGK-GAK-AX?
The UPD78F1156AGK-GAK-AX uses SuperFlash® technology licensed from Silicon Storage Technology, Inc., providing 128 KB of on-chip program memory with guaranteed 100,000 write/erase cycles and 20-year data retention at +85°C. This technology enables fast page erase (≤10 ms) and byte-level programming, supporting robust firmware update mechanisms in the field.
Can the UPD78F1156AGK-GAK-AX operate from a 3.3 V supply?
Yes, the UPD78F1156AGK-GAK-AX operates over a supply voltage range of 2.7 V to 5.5 V, making it fully compatible with standard 3.3 V logic systems. Its I/O pins are 5 V tolerant when configured as inputs, allowing direct interfacing with legacy 5 V peripherals without level-shifting circuitry - a key advantage in mixed-voltage industrial designs.
How many analog input channels does the built-in ADC support?
The UPD78F1156AGK-GAK-AX integrates a 12-bit successive-approximation ADC with a 16-channel analog multiplexer, supporting simultaneous sampling across multiple sensors. Each channel can be individually configured for differential or single-ended operation, and conversion results are accessible via DMA or interrupt-driven reads - enabling high-fidelity signal acquisition in applications such as motor current monitoring and environmental sensing.
