FAQ

What is the maximum operating frequency of the DF2317VTEBL25V?

The DF2317VTEBL25V operates with a maximum internal CPU frequency of 25 MHz, derived from an external crystal (1–20 MHz) or oscillator input. Its H8S/2000 core executes instructions at one cycle per instruction in most cases, enabling deterministic real-time performance for control applications. The DF2317VTEBL25V supports both high-speed and medium-speed operating modes, with timing parameters fully characterized up to 25 MHz in the official hardware manual.

Does the DF2317VTEBL25V support in-system programming of its flash memory?

Yes, the DF2317VTEBL25V supports full in-system programming (ISP) of its 256 KB on-chip flash memory via its built-in serial communication interface (SCI) in boot mode. The DF2317VTEBL25V implements command-based programming/erasing with checksum verification, automatic block erasure, and error codes (e.g., H'11 for checksum failure). Reprogrammability is rated for ≥100 cycles with 10-year data retention under industrial conditions.

What power-saving modes are available on the DF2317VTEBL25V?

The DF2317VTEBL25V provides five low-power operating modes: sleep mode (CPU halted, peripherals active), module stop mode (selected modules disabled), software standby mode (CPU and most peripherals halted, RAM retained), hardware standby mode (all clocks stopped, minimal current draw), and deep hardware standby with wake-up on external interrupt. In software standby, the DF2317VTEBL25V draws less than 10 μA while preserving register and RAM contents - ideal for battery-backed monitoring applications.

Can the DF2317VTEBL25V's A/D converter operate simultaneously with PWM generation?

Yes, the DF2317VTEBL25V's 10-bit A/D converter and 16-bit Timer Pulse Unit (TPU) operate independently and concurrently. The A/D converter can be triggered by TPU output compare events or external signals, enabling precise synchronized sampling - for example, capturing motor phase currents at exact PWM center points. This coordination is hardware-supported and does not require CPU intervention, ensuring jitter-free timing critical for FOC implementations using the DF2317VTEBL25V.

Is the DF2317VTEBL25V pin-compatible with other H8S/2300 series MCUs?

Yes, the DF2317VTEBL25V in LQFP-100 package is pin-compatible with other members of the H8S/2319 Group sharing the same package variant, including HD64F2319CLP and R5F21236SDFP. Pin functions, power domains, and peripheral mappings match across these variants, allowing direct substitution on existing PCBs when memory or feature requirements change - provided the target part's flash configuration and protection settings are appropriately initialized for the DF2317VTEBL25V.
