For engineers reviewing the R5F100PGAFA#30 datasheet, R5F100PGAFA#30 pinout, R5F100PGAFA#30 application, or R5F100PGAFA#30 equivalent, key selection criteria include its 100-pin LQFP package, 128 KB code flash with self-programming support, 10-bit 26-channel ADC, dual UART/LIN capability, and -40°C to +105°C industrial temperature grade (G-suffix).

Technical Context

The R5F100PGAFA#30 implements the RL78 CPU core with 3-stage pipeline CISC architecture, supporting variable instruction timing from 0.03125 μs (32 MHz HS mode) to 30.5 μs (32.768 kHz subsystem clock). It integrates a 12-bit interval timer, calendar-based real-time clock with alarm and correction, and watchdog timer powered by dedicated low-speed oscillator.

Its peripheral set includes up to 26-channel 10-bit ADC with internal 1.45 V reference and temperature sensor, 8–16 channels of 16-bit timers, 3–10 I²C/Simplified I²C channels, 2–4 UART/LIN interfaces, and 2–8 CSI (SPI-compatible) channels - all configurable via register-level control without external glue logic.

FAQ

What is the maximum operating frequency and corresponding performance of the R5F100PGAFA#30?

The R5F100PGAFA#30 operates at up to 32 MHz, delivering 41 DMIPS of processing performance. This is achieved using the RL78 CPU core's 3-stage pipeline and high-speed on-chip oscillator. The device maintains this performance across its full 1.6–5.5 V supply range and -40°C to +105°C temperature grade, making R5F100PGAFA#30 suitable for deterministic real-time control tasks in industrial environments.

Does the R5F100PGAFA#30 include integrated data flash memory, and what are its key attributes?

Yes, the R5F100PGAFA#30 includes 8 KB of on-chip data flash memory. It supports background operation (BGO), allowing program execution from code flash while rewriting data flash. Rated for 1,000,000 write/erase cycles at VDD = 1.8–5.5 V, it enables reliable non-volatile storage of calibration data, configuration parameters, or event logs without external EEPROM - a key feature distinguishing R5F100PGAFA#30 from data-flash-less variants like R5F101PGAFA#30.

What package type and pin count does the R5F100PGAFA#30 use, and how does it impact PCB design?

The R5F100PGAFA#30 uses a 100-pin LQFP package with 0.65-mm pitch and 14 × 20 mm body size. This standard footprint simplifies layout, supports automated optical inspection (AOI), and is compatible with mainstream SMT assembly processes. Unlike the 0.5-mm pitch LFQFP alternative (e.g., R5F100PGAFB#30), the R5F100PGAFA#30 requires no fine-pitch routing or enhanced stencil design, making R5F100PGAFA#30 ideal for rapid prototyping and medium-volume industrial production.

How does the R5F100PGAFA#30 support low-power system design?

The R5F100PGAFA#30 supports ultra-low-power operation through multiple hardware modes: HALT (66 μA/MHz), STOP (0.57 μA with RTC + LVD active), and SNOOZE (low-latency wake-up from peripheral events). Its on-chip power-on-reset (POR) and 14-level voltage detector (LVD) provide robust brown-out protection without external components. These features allow R5F100PGAFA#30 to serve as the primary controller in battery-powered devices such as wireless sensors and portable medical instruments.

Which communication interfaces are integrated into the R5F100PGAFA#30, and how are they configured?

The R5F100PGAFA#30 integrates up to 4 UART/LIN channels, 3–10 I²C/Simplified I²C channels, and 2–8 CSI (SPI-compatible) channels - all mapped to flexible GPIO pins with programmable alternate functions. Each interface supports independent clock sources and interrupt-driven operation. For example, P10 and P11 can be configured as SCK00/SDA00 (I²C) or SCK00/RxD0 (UART), enabling dynamic protocol selection in R5F100PGAFA#30-based systems without hardware changes.
