FAQ
What is the maximum operating frequency and corresponding DMIPS rating for the R5F104PHGFA#10?
The R5F104PHGFA#10 operates at up to 32 MHz with a measured performance of 44 DMIPS. This is achieved using the RL78 CPU core's 3-stage pipeline and optimized instruction set, including hardware multiply/divide. The high-speed on-chip oscillator supports this frequency without external components, and timing-critical applications benefit from deterministic execution within the 0.03125 µs minimum instruction cycle.
Does the R5F104PHGFA#10 support background data flash rewriting while executing application code?
Yes, the R5F104PHGFA#10 supports background operation (BGO) for its 8 KB data flash memory. This allows the CPU to execute instructions from program memory while simultaneously erasing or programming data flash sectors - essential for logging, parameter storage, or firmware updates without interrupting real-time tasks. The flash library uses RAM starting at address FE900H for this operation.
What are the key differences between the R5F104PHGFA#10 and R5F104PHGFB#10?
The R5F104PHGFA#10 and R5F104PHGFB#10 share identical electrical specifications, memory map, and peripheral set. Their only difference is packaging: R5F104PHGFA#10 uses a 48-pin LFQFP (7 × 7 mm, 0.5 mm pitch), while R5F104PHGFB#10 uses a 48-pin HWQFN with exposed thermal pad. The LFQFP variant offers easier rework and optical inspection; the HWQFN provides lower thermal resistance for high-power analog or PWM workloads.
How many analog input channels does the 10-bit ADC in the R5F104PHGFA#10 support, and what reference options are available?
The R5F104PHGFA#10 integrates a 10-bit successive-approximation ADC with 12 analog input channels (ANI0–ANI11). It supports both external reference (AVREFP/AVREFM pins) and internal 1.45 V reference voltage. The internal reference enables ratiometric measurements without external components, while differential input mode improves noise immunity in industrial signal conditioning.
Is the R5F104PHGFA#10 pin-compatible with other RL78/G14 variants in the same package type?
Yes, all RL78/G14 MCUs in the 48-pin LFQFP package - including R5F104PHGFA#10, R5F104PGGFA#10, and R5F104LHGFA#10 - share identical pinouts and electrical characteristics. This enables scalable design reuse: firmware and layout can be retained while upgrading flash/RAM capacity or temperature grade without hardware modification.
