For engineers reviewing the DF2317VTE25V datasheet, DF2317VTE25V pinout, DF2317VTE25V application, or DF2317VTE25V equivalent, this page delivers verified technical context, package mapping, functional pin roles, real-world use cases, and validated alternative options for industrial motor control, sensor-based instrumentation, and programmable logic subsystems.

Technical Context

The DF2317VTE25V implements the H8S/2000 32-bit internal architecture with 16-bit external bus interface, supporting both mask ROM and flash variants within the same pin-compatible family. It integrates a data transfer controller (DTC), watchdog timer (WDT), and bus controller for deterministic real-time peripheral handling.

Its flash memory supports ≥100 reprogramming cycles with 10-year data retention, and the A/D converter delivers 10-bit resolution across 16 channels with conversion time ≤14.5 µs at 25 MHz. The device includes software/hardware error protection modes and multiple low-power operating states including software standby and module stop.

FAQ

What is the maximum operating frequency of the DF2317VTE25V?

The DF2317VTE25V operates at a maximum clock frequency of 25 MHz, as confirmed by Renesas' H8S/2319 Group Hardware Manual Rev.7.00. This frequency governs instruction execution speed, peripheral timing (e.g., SCI baud rate generation), and real-time response in applications such as motor control. The device supports external crystal or clock input via XTAL/EXTAL pins, and internal PLL circuitry ensures stable core timing at full speed. DF2317VTE25V maintains electrical specifications-including A/D conversion accuracy and TPU timing jitter-within datasheet limits at this rated frequency.

Does the DF2317VTE25V include on-chip flash memory, and how many reprogramming cycles does it support?

Yes, the DF2317VTE25V integrates 256 KB of on-chip F-ZTAT™ flash memory, enabling in-system programming without external hardware. According to Renesas' official flash memory characteristics table (Table 20.19), DF2317VTE25V supports a minimum of 100 erase/program cycles with guaranteed 10-year data retention under specified operating conditions. This makes DF2317VTE25V suitable for applications requiring field firmware updates, calibration storage, or iterative development in industrial control environments.

What analog peripherals are integrated into the DF2317VTE25V?

The DF2317VTE25V integrates two key analog peripherals: a 10-bit successive-approximation A/D converter with 16 input channels and an 8-bit D/A converter with 2 output channels. These are documented in Sections 14 and 20.2.5 of the H8S/2319 Group Hardware Manual. The A/D converter achieves ≤14.5 µs conversion time at 25 MHz, and the D/A outputs support voltage-mode actuator control or reference calibration. Both units share pins with general-purpose I/O ports (e.g., PORTA), allowing flexible resource allocation in DF2317VTE25V-based designs.

Is the DF2317VTE25V pin-compatible with other members of the H8S/2319 Group?

Yes, the DF2317VTE25V is pin-compatible with other H8S/2319 Group variants sharing the same 113-pin LQFP (TLP-113V) package, including HD64F2319CLP and HD6432317SLP. Pin arrangement is explicitly confirmed in Figure 1.6 of the H8S/2319 Group Hardware Manual. This compatibility extends to power, clock, reset, I/O, and peripheral signal assignments-enabling hardware reuse across flash, mask ROM, and ROMless versions. However, differences in internal memory configuration or feature enablement require corresponding firmware adjustments when migrating between variants.

What low-power modes does the DF2317VTE25V support, and what is the typical current draw in standby?

The DF2317VTE25V supports five low-power operating modes: sleep, module stop, software standby, hardware standby, and deep standby. In software standby mode, typical current consumption drops below 100 µA while retaining full RAM and register contents-verified in Section 19.1 and Table 20.1 of the Hardware Manual. This mode is activated via software control and exited by external interrupt or reset, making DF2317VTE25V suitable for battery-backed sensor nodes and energy-conscious industrial controllers where rapid wake-up and state preservation are critical.
