Technical Context

The DF38004H10V implements the H8/300L CPU architecture with instruction set compatibility to the H8/300, supporting 16-bit address space and on-chip memory-mapped peripherals. It includes dedicated system-control modules: power-on reset (POR), low-voltage detection (LVD), and watchdog timer (WDT) with discrete configuration.

Peripheral integration centers on real-time control: one 8-bit clock timer (Timer A), one 16-bit compare timer (Timer F), one AEC timer, SCI for asynchronous serial communication, and a static LCD driver capable of 100 segments via multiplexing - all accessible through dedicated I/O ports totaling 54 pins (9 input, 6 output, 39 I/O).

FAQ

What is the maximum operating frequency of the DF38004H10V?

The DF38004H10V operates at a maximum frequency of 16 MHz when powered within its specified 4.5 V to 5.5 V supply range. This frequency is achieved using an external crystal or resonator connected to OSC1/OSC2 pins, and it defines the upper limit for instruction execution speed and peripheral timing resolution in applications such as motor control or sensor sampling.

Does the DF38004H10V include an on-chip ADC?

Yes, the DF38004H10V integrates a 10-bit successive approximation register (SAR) ADC with four input channels. This ADC supports single-ended analog input measurements with 1024 quantization levels, enabling direct interface with temperature sensors, potentiometers, or voltage dividers without external signal conditioning in many embedded designs.

What package type is used for the DF38004H10V?

The DF38004H10V is packaged in a 64-pin FP-64A plastic flat package (20.0 × 14.0 × 2.2 mm, 0.5 mm lead pitch). This surface-mount package is compatible with standard reflow soldering processes and shares footprint compatibility with other FP-64 variants in the H8/38004 Group, including FP-64E and FP-64K.

Is the DF38004H10V pin-compatible with other H8/38004 Group members?

Yes, the DF38004H10V shares identical pin assignment and electrical characteristics with all members of the H8/38004 Group in the FP-64A package, including H8/38004H10V and DF38004H10F (FP-64E). Pin-to-pin compatibility is confirmed in Renesas' Hardware Manual Rev.7.00, allowing hardware reuse across variants where memory or package differences are acceptable.

What is the memory configuration of the DF38004H10V?

The DF38004H10V features 16 kB of mask-programmed ROM for firmware storage and 1 kB of on-chip RAM for runtime data and stack operations. The mask ROM provides fixed, tamper-resistant program storage ideal for high-volume production, while the RAM supports variable allocation for buffers, control structures, and interrupt service routines in the DF38004H10V's embedded applications.
