Product details
Overview
R5F101PJAFB#30 from Renesas is a 100-pin LFQFP, 0.5-mm pitch, industrial-grade 16-bit RL78/G13 microcontroller with 96 KB flash, 8 KB RAM, and no data flash memory. It operates from 1.6 V to 5.5 V, delivers 41 DMIPS at 32 MHz, and supports ultra-low-power modes (0.57 μA in RTC+LVD mode), targeting battery-powered industrial sensors and motor control interfaces.
For engineers reviewing the R5F101PJAFB#30 datasheet, R5F101PJAFB#30 pinout, R5F101PJAFB#30 application, or R5F101PJAFB#30 equivalent, key selection criteria include its 100-pin LFQFP-0.5mm package, absence of on-chip data flash, -40°C to +85°C industrial temperature rating (D-grade), integrated 10-bit ADC (26 channels), real-time clock with calendar, and dual UART/LIN support for embedded control systems.
Technical Context
The R5F101PJAFB#30 implements the RL78 CPU core with 3-stage pipeline CISC architecture, supporting instruction execution times from 0.03125 μs (32 MHz HS mode) to 30.5 μs (32.768 kHz subsystem clock). It integrates a high-accuracy ±1.0% on-chip oscillator (selectable 1–32 MHz), DMA controller (4 channels), and hardware multiplier/divider for efficient signal processing.
Its peripheral set includes up to 16× 16-bit timers, 3× I²C/Simplified I²C interfaces, 2× UART/LIN channels, 2× CSI (SPI-compatible) interfaces, and an 8/10-bit A/D converter with internal 1.45 V reference and temperature sensor - all configurable without external components for compact industrial node designs.

FAQ
What is the maximum operating frequency and performance of the R5F101PJAFB#30?
The R5F101PJAFB#30 operates at up to 32 MHz with the RL78 CPU core, delivering 41 DMIPS of processing performance. Its minimum instruction execution time is 0.03125 μs in high-speed mode using the on-chip oscillator, enabling deterministic real-time control loops essential for motor and sensor applications. The R5F101PJAFB#30 maintains this performance across its full 1.6 V to 5.5 V supply range.
Does the R5F101PJAFB#30 include on-chip data flash memory?
No, the R5F101PJAFB#30 does not include on-chip data flash memory. This variant belongs to the "101" series, which omits data flash to reduce cost and die size. In contrast, the "100" series (e.g., R5F100PJAFB#30) includes 4 KB of data flash. The R5F101PJAFB#30 retains full 96 KB code flash and supports self-programming of that code memory only.
What package type and pin count does the R5F101PJAFB#30 use?
The R5F101PJAFB#30 uses a 100-pin LFQFP package with 0.5 mm pitch and 14 mm × 14 mm body size (RENESAS code PLQP0100KE-A). The "FB" suffix in the part number explicitly denotes the LFQFP-0.5mm variant, distinguishing it from the LQFP-0.65mm ("FP") and other package options in the RL78/G13 family.
What is the operating temperature grade of the R5F101PJAFB#30?
The R5F101PJAFB#30 is rated for industrial operation from -40°C to +85°C (D-grade), as indicated by the "D" in its full ordering designation R5F101PJAFB#30. It is not rated for the extended -40°C to +105°C (G-grade) range. This makes it suitable for factory-floor equipment, building automation, and outdoor industrial enclosures with active thermal management.
Which communication interfaces are supported by the R5F101PJAFB#30?
The R5F101PJAFB#30 supports multiple serial interfaces: up to 4 UART/LIN channels (with hardware LIN break detection), up to 10 I²C/Simplified I²C channels, and up to 8 CSI (SPI-compatible) channels. All are configurable via software registers and share pins with GPIO, allowing flexible peripheral allocation without additional level-shifting or bus arbitration ICs in the R5F101PJAFB#30 design.
