FAQ
What is the maximum operating frequency and corresponding supply voltage range for the R7F100GJG3CFA#HA0?
The R7F100GJG3CFA#HA0 supports a maximum CPU operating frequency of 32 MHz using the high-speed on-chip oscillator, with guaranteed operation across the full 1.6–5.5 V supply range. At 32 MHz, the minimum instruction execution time is 0.03125 µs. The device also supports ultra-low-speed operation at 32.768 kHz for RTC and standby functions, maintaining functionality down to 1.6 V.
Does the R7F100GJG3CFA#HA0 support hardware debugging, and what interface is used?
Yes, the R7F100GJG3CFA#HA0 includes full on-chip debugging capability via the dedicated TOOLRxD/TOOLTxD pins (P11/P12), compatible with Renesas E2 emulator and CS+ IDE. Debugging supports breakpoints, watchpoints, memory inspection, and flash programming without requiring external JTAG adapter - all functions operate within the same 52-pin LQFP footprint.
How many capacitive touch channels does the R7F100GJG3CFA#HA0 support, and what configurations are available?
The R7F100GJG3CFA#HA0 integrates the CTSU2L unit supporting up to 64 keys in mutual-capacitance mode (8×8 matrix) or 32 keys in self-capacitance mode. It operates across the full 1.8–5.5 V supply range and includes hardware noise cancellation. Pin assignments for touch channels (e.g., TS00–TS05, TS20–TS27) are fixed per the 52-pin LQFP pinout and require no external components beyond standard decoupling.
What are the data retention capabilities of the R7F100GJG3CFA#HA0's RAM and data flash memory?
The R7F100GJG3CFA#HA0 guarantees data retention in its 24 KB on-chip RAM at 210 nA current draw under VDD = 1.6–5.5 V and TA = −40°C to +105°C. Its 8 KB data flash memory supports 1,000,000 write/erase cycles (typical) with background operation enabled - allowing concurrent code execution and nonvolatile parameter updates without system interruption.
Can the R7F100GJG3CFA#HA0 operate from a single 3.3-V supply, and are its I/Os 5-V tolerant?
Yes, the R7F100GJG3CFA#HA0 operates fully across 1.6–5.5 V, including standard 3.3-V systems. Its general-purpose I/Os are not 5-V tolerant by default; however, specific pins (P10–P17, P60–P62, P30–P31) support 5-V-tolerant input when configured in TTL mode with internal pull-up - verified per Renesas specification for 52-pin LQFP variants. External level shifters are required for 5-V output drive.
