FAQ

What is the maximum operating frequency and corresponding DMIPS rating for the R5F100MHGFA#30?

The R5F100MHGFA#30 operates at up to 32 MHz using its high-speed on-chip oscillator and delivers 41 DMIPS performance. This metric is measured under standard conditions (VDD = 1.8–5.5 V, TA = −40°C to +105°C) and reflects the RL78 CPU core's 3-stage pipeline efficiency. The R5F100MHGFA#30 maintains this performance across its full industrial temperature range without derating.

Does the R5F100MHGFA#30 support background data flash rewriting (BGO), and what is the guaranteed endurance?

Yes, the R5F100MHGFA#30 supports background data flash rewriting (BGO), allowing program execution from code flash while simultaneously updating data flash contents. Its 8 KB data flash is rated for 1,000,000 write/erase cycles (typical) at VDD = 1.8–5.5 V. The R5F100MHGFA#30 uses flash library RAM starting at address FAF00H, which must be reserved in the linker configuration.

What package type and pin pitch does the R5F100MHGFA#30 use, and is it RoHS compliant?

The R5F100MHGFA#30 uses an 80-pin LFQFP package (12 × 12 mm body, 0.5-mm pin pitch) with lead-free, RoHS-compliant finish. Its packaging specification is PLQP0080KE-A (tray) or PLQP0080KB-B (tape/reel), and it meets JEDEC MSL Level 3 moisture sensitivity requirements. The R5F100MHGFA#30 is compatible with standard reflow profiles for lead-free soldering.

How many analog input channels and what ADC resolution does the R5F100MHGFA#30 provide?

The R5F100MHGFA#30 integrates a 10-bit successive-approximation ADC with up to 26 analog input channels (ANI0–ANI25), supporting both single-ended and differential measurements. It includes an internal 1.45 V reference voltage and a calibrated temperature sensor usable in HS (high-speed main) mode. The R5F100MHGFA#30 supports programmable sample-and-hold timing and scan-mode conversion for efficient multi-channel acquisition.

What low-power modes are available on the R5F100MHGFA#30, and what is the lowest achievable current draw?

The R5F100MHGFA#30 supports HALT, STOP, and SNOOZE low-power modes. In STOP mode with only RTC and LVD active, it achieves 0.57 μA typical current draw at VDD = 1.8–5.5 V and TA = −40°C to +105°C. SNOOZE mode allows selected peripherals (e.g., UART, CSI) to remain active while CPU halts-enabling wake-up on serial activity or timer match without full restart overhead. The R5F100MHGFA#30 achieves 66 μA/MHz in active mode.
