FAQ

What is the maximum operating frequency of the UPD78F1515AGC(R)-UEU-AX?

The UPD78F1515AGC(R)-UEU-AX supports a maximum main system clock frequency of 20 MHz using an external crystal or ceramic resonator. It also includes an internal high-speed oscillator (HOCO) rated at 20 MHz with ±2% accuracy over temperature and voltage, enabling reliable operation without external timing components in less demanding applications. The CPU executes instructions at one cycle per instruction for most operations.

Does the UPD78F1515AGC(R)-UEU-AX include on-chip debug capability?

Yes, the UPD78F1515AGC(R)-UEU-AX integrates a full IEEE 1149.1-compliant JTAG debug interface supporting real-time breakpoints, register inspection, and flash programming without requiring external emulator hardware. This on-chip debug circuit is enabled by default and requires only a standard JTAG adapter (e.g., E2 emulator) for development - no additional debug pins or configuration fuses are needed beyond the standard TCK/TMS/TDO/TDI connections.

What is the Flash memory endurance specification for the UPD78F1515AGC(R)-UEU-AX?

The UPD78F1515AGC(R)-UEU-AX guarantees 100,000 write/erase cycles for its 128 KB on-chip Flash memory under industrial temperature conditions (−40°C to +85°C). This endurance rating applies to both block erase and page write operations and is validated per JEDEC standards. Field firmware updates using in-application programming (IAP) remain viable across the full product lifetime when wear-leveling is implemented in host software.

Can the UPD78F1515AGC(R)-UEU-AX operate from a 3.3 V supply?

Yes, the UPD78F1515AGC(R)-UEU-AX operates across a supply voltage range of 2.7 V to 5.5 V, fully supporting standard 3.3 V systems. All I/O pins are 5 V tolerant when configured as inputs, allowing direct interface with legacy 5 V peripherals without level-shifting circuitry. Internal voltage regulators maintain stable core and analog domain voltages across this range, ensuring consistent ADC accuracy and timing performance at 3.3 V operation.

How many ADC input channels does the UPD78F1515AGC(R)-UEU-AX support?

The UPD78F1515AGC(R)-UEU-AX integrates a 10-bit successive-approximation ADC with 16 selectable input channels (AN0 through AN15), accessible via Port 2 (P20–P27), Port 4 (P40–P41), and Port 15 (P150–P152, P157). The ADC includes built-in sample-and-hold, programmable conversion clock prescaler, and automatic channel scanning mode - enabling continuous monitoring of multiple analog sensors with minimal CPU overhead.
