FAQ

What is the operating voltage range for DF2211FP24V?

The DF2211FP24V operates from 4.5 V to 5.5 V on its VCC pins. This 5 V nominal supply supports direct interfacing with legacy TTL/CMOS logic and industrial I/O standards. Operation outside this range may cause functional failure or permanent damage. Decoupling capacitors (0.1 µF ceramic + 10 µF tantalum per VCC pin) are required per Renesas Hardware Manual Rev.7.00 to ensure stable core and peripheral operation under dynamic load conditions. DF2211FP24V does not support 3.3 V operation.

Does DF2211FP24V support in-circuit debugging via JTAG?

Yes, DF2211FP24V supports IEEE 1149.1 boundary-scan debugging via dedicated TMS, TCK, TDO, and TDI pins (pins 54, 53, 52, and 56 in FP-64E package). The TRST pin is NC in this variant, so reset is handled through the RES pin. This allows full visibility into internal registers and memory during development, enabling hardware validation and firmware bring-up without intrusive probes. DF2211FP24V implements the complete TAP controller as specified in the H8S/2212 Group Hardware Manual.

What is the maximum clock frequency supported by DF2211FP24V?

DF2211FP24V supports a maximum main clock frequency of 25 MHz, achievable using an external crystal (EXTAL/XTAL) or oscillator input. The internal PLL is not present in this variant; clock multiplication is not supported. At 25 MHz, instruction execution achieves approximately 16.7 MIPS (based on H8S/2000 core metrics), enabling sub-60 ns interrupt latency and tight control loop timing. DF2211FP24V must be operated within this limit to guarantee timing compliance across all peripherals including TPU, SCI, and A/D converter.

Can DF2211FP24V operate in low-power modes?

Yes, DF2211FP24V supports multiple low-power modes including Sleep and Stop, controlled via the STBY pin and system control registers. In Sleep mode, the CPU halts while peripherals like RTC, SCI, and A/D continue operating; in Stop mode, all clocks except sub-clock are gated, retaining RAM contents and RTC function. Wake-up sources include external interrupts, SCI receive events, and RTC alarms. DF2211FP24V's power consumption drops to ~100 µA in Stop mode with RTC active, making it suitable for battery-backed applications where extended standby is required.

Is DF2211FP24V RoHS compliant and qualified for industrial use?

Yes, DF2211FP24V is RoHS compliant (lead-free, halogen-free) and rated for industrial temperature range (–40°C to +85°C). It carries the "Standard" quality grade per Renesas documentation, meaning it is qualified for use in industrial robots, test and measurement equipment, and factory automation systems - but not for automotive, medical life-support, or aerospace applications. Compliance is verified per EU Directive 2011/65/EU and documented in Renesas' material declarations available upon request.
