FAQ

What is the maximum operating frequency of the DF2212UFP24V?

The DF2212UFP24V operates at a maximum CPU frequency of 25 MHz, achieved using the on-chip PLL with an external crystal (1–20 MHz range). This frequency determines instruction throughput and real-time response capability - for example, a 100 µs control loop requires ≤2,500 instructions per cycle. The DF2212UFP24V maintains timing integrity across its specified industrial temperature range (−40°C to +85°C) without derating.

Does the DF2212UFP24V support in-system programming via USB?

Yes, the DF2212UFP24V supports USB boot mode, enabling full firmware download, erase, and programming directly over USB without external debug hardware. This capability relies on the integrated USB 1.1 transceiver and on-chip bootloader - verified in Renesas Hardware Manual Rev.7.00. The DF2212UFP24V enters USB boot mode upon reset when MD0–MD2 pins are configured to 001, allowing rapid iteration during development and secure field updates.

What package type and pin count does the DF2212UFP24V use?

The DF2212UFP24V uses a 64-pin FP-64E (Fine Pitch Plastic QFP) package with 0.5 mm lead pitch and 10 mm × 10 mm body size, compliant with JEDEC MO-220. This package matches the pinout of other H8S/2212 Group variants in the same footprint, including HD64F2212 and HD64F2211U. The DF2212UFP24V's pin assignments - such as TDO/P77*, TCK/P76*, and USPND/TMOW - are documented in Figures 1.9 and 1.11 of the official hardware manual.

How much on-chip memory does the DF2212UFP24V include?

The DF2212UFP24V integrates 128 KB of on-chip Flash memory (F-ZTAT™ technology) and 12 KB of RAM. The Flash supports single-cycle read access and block erase/write operations, while the RAM is used for stack, heap, and runtime variables. This memory configuration is identical across all USB-boot variants in the H8S/2212 Group, including DF2212UFP24V, HD64F2212U, and HD64F2212CU - ensuring consistent code portability and toolchain support.

Is the DF2212UFP24V pin-compatible with other H8S/2212 Group MCUs?

Yes, the DF2212UFP24V is pin-compatible with other H8S/2212 Group members in the FP-64E package, including HD64F2212, HD64F2212U, and HD64F2211U. All share identical pin functions, electrical characteristics, and mechanical footprint - confirmed in Section 1.3 (Pin Arrangements) of the Renesas H8S/2212 Group Hardware Manual Rev.7.00. This allows drop-in replacement for functional upgrades (e.g., adding USB boot) without PCB redesign, provided the target application leverages only shared peripherals.
