FAQ

What is the maximum operating frequency of the UPD78F1504AGC-UEU-E2-AX?

The UPD78F1504AGC-UEU-E2-AX supports a maximum system clock frequency of 20 MHz using its internal high-speed oscillator (HOCO) or an external crystal. When configured with the on-chip PLL, the core can operate at up to 20 MHz while maintaining stable timing margins across voltage and temperature ranges. This frequency enables real-time execution of motor control algorithms and sensor fusion tasks without external clock synthesis.

Does the UPD78F1504AGC-UEU-E2-AX include on-chip debug capability?

Yes, the UPD78F1504AGC-UEU-E2-AX includes full on-chip debug support compliant with Renesas' standard debug interface. It works natively with the QB-MINI2 on-chip debugger, enabling breakpoints, real-time variable watch, and instruction trace without requiring external JTAG adapters. Debug functionality remains active even during low-power stop modes with RTC enabled, allowing deep sleep validation.

What is the Flash memory endurance specification for the UPD78F1504AGC-UEU-E2-AX?

The UPD78F1504AGC-UEU-E2-AX specifies 100,000 write/erase cycles for its 128 KB on-chip Flash memory, verified per JEDEC JESD22-A117. Each 128-byte page can be independently erased, supporting robust firmware update mechanisms. Data retention is guaranteed for 20 years at 85°C ambient, making it suitable for field-deployed devices requiring long-term reliability without external nonvolatile storage.

How many analog input channels does the UPD78F1504AGC-UEU-E2-AX support?

The UPD78F1504AGC-UEU-E2-AX integrates a 10-bit successive-approximation ADC with 24 configurable analog input channels. These channels map across multiple port pins (e.g., P00–P07, P10–P17, P50–P57) and support simultaneous sampling when used with the internal sample-and-hold circuit. Input voltage range is programmable from 0–VREFP or 0–AVDD, with optional PGA gain settings for low-level signal conditioning.

What package type and pin count does the UPD78F1504AGC-UEU-E2-AX use?

The UPD78F1504AGC-UEU-E2-AX is supplied in a 100-pin LQFP package (14 mm × 14 mm, 0.5 mm pitch) with exposed thermal pad (EP). This JEDEC-standard MS-026BAC footprint supports automated optical inspection and reflow soldering. Pin assignments match Renesas' 78K0R/LG3 family layout, ensuring PCB design reuse across variants like UPD78F1503A and UPD78F1505A.
