FAQ
What is the maximum operating frequency and power consumption of the R7F101G6E4CSP#CA1?
The R7F101G6E4CSP#CA1 operates at up to 48 MHz with a typical active current of 50 µA per MHz. At full speed, this translates to approximately 2.4 mA total active current, validated across its 1.6–5.5 V supply range and –40°C to +105°C industrial temperature grade. The device achieves this efficiency through Renesas' proprietary low-power process and dynamic clock gating.
Does the R7F101G6E4CSP#CA1 support DALI-2 communication natively?
Yes, the R7F101G6E4CSP#CA1 includes dedicated hardware support for DALI-2 communication, including signal timing compliance, frame detection, and error handling logic. Its P00 and P01 pins serve as DALITxD0 and DALIRxD0, respectively, enabling direct connection to DALI bus transceivers without external protocol ICs - confirmed in the RL78/G24 datasheet section 1.1 and Table 1-2.
What are the key differences between R7F101G6E4CSP#CA1 and R7F101G6G4CSP#CA1?
The R7F101G6E4CSP#CA1 and R7F101G6G4CSP#CA1 share identical 20-pin LSSOP packaging, pinout, peripherals, and operating specifications. Their sole difference is code flash capacity: R7F101G6E4CSP#CA1 has 64 KB, while R7F101G6G4CSP#CA1 has 128 KB. Both use the same #CA1 magazine packaging and support identical industrial temperature range (–40°C to +105°C).
Can the R7F101G6E4CSP#CA1 perform simultaneous analog sampling?
Yes, the R7F101G6E4CSP#CA1's 12-bit ADC includes two independent sample-and-hold circuits, allowing true simultaneous sampling across two analog input channels (e.g., ANI0 and ANI1). This capability is explicitly documented in the RL78/G24 datasheet section "A/D converter" and enables accurate current/voltage vector acquisition in motor control and power supply applications.
What debug interface does the R7F101G6E4CSP#CA1 use, and is external hardware required?
The R7F101G6E4CSP#CA1 uses the single-pin TOOL0 interface (pin 1) for on-chip debugging and programming. It is fully compatible with Renesas E2 emulator and E2 studio IDE without requiring additional debug probes or level shifters - the interface operates at the device's VDD voltage and supports flash programming, breakpoint setting, and real-time variable monitoring.
