FAQ
What is the maximum operating frequency and corresponding DMIPS rating of the R5F104PFDFB#30?
The R5F104PFDFB#30 operates at up to 32 MHz and delivers 44 DMIPS (Dhrystone MIPS) under standard conditions. This performance level is achieved using the RL78 CPU core's 3-stage pipeline and optimized instruction set, enabling deterministic real-time response for motor control and sensor fusion tasks within the R5F104PFDFB#30's 96 KB flash constraint.
Does the R5F104PFDFB#30 support hardware-accelerated peripheral chaining, and how is it implemented?
Yes, the R5F104PFDFB#30 implements the Event Link Controller (ELC), which enables direct hardware-level linking of up to 26 peripheral events - for example, triggering ADC conversion upon timer match, then automatically transferring results via DTC to RAM without CPU involvement. This capability is fully documented in the R5F104PFDFB#30's R01DS0053EJ0370 datasheet Section 1.1 and eliminates software overhead in time-critical signal chains.
What are the exact flash and RAM capacities of the R5F104PFDFB#30, and how are they allocated?
The R5F104PFDFB#30 contains 96 KB of on-chip code flash memory and 12 KB of RAM. Flash is organized in 1 KB blocks with security features including block erase prohibition; RAM includes dedicated areas for stack, heap, and peripheral register shadowing. These values are explicitly listed in Table 1-1 (Page 2) of the R5F104PFDFB#30 datasheet R01DS0053EJ0370 Rev. 3.70 under the "R5F104xF" row.
Which low-power modes does the R5F104PFDFB#30 support, and what is the current draw in each?
The R5F104PFDFB#30 supports HALT (66 μA/MHz), STOP (0.60 μA), and SNOOZE modes. In STOP mode, only RTC and LVD remain active - critical for long-term battery operation. All modes retain RAM content and allow wake-up via external interrupt, RTC alarm, or comparator event. These specifications are measured at VDD = 3.0 V, TA = 25°C per Section 1.1 of the R5F104PFDFB#30 datasheet.
Is the R5F104PFDFB#30 pin-compatible with other RL78/G14 variants in the same 48-pin LFQFP package?
Yes, all RL78/G14 devices in the 48-pin LFQFP (FB) package - including R5F104PFDFB#30, R5F104PGDFB#30, and R5F104LEAFB#30 - share identical pinout, electrical characteristics, and mechanical footprint (PLQP0048KF-A). This allows direct substitution within the same PCB layout when memory or feature requirements change, as confirmed in Renesas' Table 1-1 and Package Outline Drawing PLQP0048KF-A.
