FAQ

What is the maximum operating frequency of the HD6417040ACF28V?

The HD6417040ACF28V operates at a maximum clock frequency of 28 MHz, as confirmed in Renesas' SH7040 Series Hardware Manual Rev.6.00. This frequency defines the upper limit for CPU instruction execution and peripheral timing - for example, the 10-bit A/D converter's conversion time scales linearly with clock speed, and bus access cycles are derived directly from this master clock. Operation above 28 MHz is not supported and may cause functional failure.

Does the HD6417040ACF28V support 3.3 V operation?

Yes, the HD6417040ACF28V supports dual supply operation: it is fully specified for both 5 V and 3.3 V Vcc, as documented in the "Notes on the SH7040 Series Specifications" table for the SH7040A variant. The "CF28" suffix denotes the 28 MHz speed grade with copper-lead QFP2020-112 packaging, and electrical characteristics are guaranteed across both voltage rails within the –20°C to +75°C temperature range.

What type of on-chip memory does the HD6417040ACF28V include?

The HD6417040ACF28V integrates 64 kB of on-chip mask ROM, as explicitly stated in the SH7040 Series Hardware Manual's specification tables. This ROM is factory-programmed and immutable in the field - it serves as the primary program storage, eliminating the need for external boot memory. No RAM, flash, or PROM is included on-die; external memory must be added for data storage or code updates.

Is the HD6417040ACF28V pin-compatible with other SH7040 Series devices?

Yes, the HD6417040ACF28V uses the QFP2020-112 package and shares identical pin assignment with other SH7040A variants in the same package footprint, including HD6437040AF28 and HD6477042ACF28. Pin functions such as CK, RES, A0–A21, D0–D15, CS0/CS1, and AN0–AN7 are electrically and physically aligned - enabling drop-in replacement where memory size or voltage requirements permit.

What A/D converter specifications apply to the HD6417040ACF28V?

The HD6417040ACF28V features an 8-channel, 10-bit successive approximation register (SAR) A/D converter with ±4 LSB integral nonlinearity (INL), classified as "mid-speed" in Renesas documentation. It supports software, timer, or external pin triggering, and its analog inputs (AN0–AN7) require external RC filtering per Figure 15.14 in the hardware manual to meet specified accuracy under noise conditions.
