FAQ
What is the maximum operating frequency of the R5F100LHABG#U0?
The R5F100LHABG#U0 operates at up to 32 MHz using its high-accuracy on-chip oscillator (±1.0% over −20°C to +85°C). At this speed, it delivers 41 DMIPS performance while maintaining 66 μA/MHz active current consumption - enabling responsive real-time control without excessive power draw. The R5F100LHABG#U0 also supports lower-frequency subsystem clocks (e.g., 32.768 kHz) for ultra-low-power RTC and wake-up operations.
Does the R5F100LHABG#U0 support in-system programming via standard interfaces?
Yes, the R5F100LHABG#U0 supports in-system programming through its on-chip debug interface using Renesas E2 emulator or compatible tools. It implements self-programming with boot swap and flash shield window functions, allowing secure firmware updates without external programmers. The R5F100LHABG#U0 does not require dedicated ISP pins - programming uses standard debug pins (e.g., RESET, SWCLK, SWDIO) in boundary-scan-compatible mode.
What are the key differences between R5F100LHABG#U0 and R5F101LHABG#U0?
The R5F100LHABG#U0 includes 8 KB of data flash memory with background operation (BGO) and 1M-cycle endurance, while the R5F101LHABG#U0 omits data flash entirely. Both share identical 128 KB code flash, 12 KB RAM, VFBGA-64 package, and industrial −40°C to +105°C rating. The R5F100LHABG#U0 is selected when onboard nonvolatile parameter storage or field-updatable calibration data is required; the R5F101LHABG#U0 reduces cost where external EEPROM or flash suffices.
Can the R5F100LHABG#U0 operate from a single 1.8 V supply?
Yes, the R5F100LHABG#U0 supports operation from 1.6 V to 5.5 V, fully covering 1.8 V nominal supply rails. At 1.8 V, it can run at reduced maximum frequency (up to ~16 MHz per datasheet voltage-frequency curves) while retaining full peripheral functionality including ADC, RTC, and serial interfaces. This enables direct integration with low-voltage battery systems and mixed-signal domains without level-shifting.
Is the R5F100LHABG#U0 pin-compatible with other RL78/G13 variants in VFBGA-64 packaging?
Yes, all RL78/G13 devices in the VFBGA-64 package (e.g., R5F100LCABG#U0, R5F100LDABG#U0, R5F100LEABG#U0, R5F100LFABG#U0, R5F100LGABG#U0, R5F100LHABG#U0, R5F100LJABG#U0) share identical pinouts and ball assignments. This allows hardware reuse across memory/configurations - for example, designing one PCB that supports 16 KB to 128 KB flash variants solely via firmware and BOM changes. The R5F100LHABG#U0 is fully drop-in compatible within this group.
