Product details
Overview
R5F101PGAFB#30 from Renesas is a 32-bit RL78/G13 microcontroller with 96 KB flash, 8 KB RAM, and no data flash memory, housed in a 100-pin LFQFP (14 × 14 mm, 0.5-mm pitch) package. It operates from 1.6 V to 5.5 V, delivers 41 DMIPS at 32 MHz, and supports ultra-low-power modes including STOP (0.57 μA) and HALT for battery-powered industrial sensors and metering systems.
For engineers reviewing the R5F101PGAFB#30 datasheet, R5F101PGAFB#30 pinout, R5F101PGAFB#30 application, or R5F101PGAFB#30 equivalent, key selection criteria include its 100-pin LFQFP footprint, absence of on-chip data flash, -40°C to +85°C industrial temperature grade (D), integrated RTC and 10-bit ADC with 26 channels, and support for LIN-bus via UART.
Technical Context
The R5F101PGAFB#30 implements the RL78 CPU core with CISC architecture and 3-stage pipeline, enabling instruction execution times from 0.03125 μs (32 MHz high-speed mode) to 30.5 μs (32.768 kHz subsystem clock). It integrates a 12-bit interval timer, real-time clock with calendar/alarm functions, and watchdog timer driven by a dedicated low-speed on-chip oscillator.
Peripheral integration includes up to 16 channels of 16-bit timers, 3–10 I²C/Simplified I²C channels, 2–4 UART/LIN interfaces, 2–8 CSI (SPI-compatible) channels, and an 8/10-bit A/D converter with internal 1.45 V reference and temperature sensor - all operating across the full 1.6–5.5 V supply range.

FAQ
What is the flash memory configuration of the R5F101PGAFB#30?
The R5F101PGAFB#30 contains 96 KB of code flash memory and no on-chip data flash memory - consistent with the "101" series designation in the RL78/G13 family. This configuration eliminates background data flash erase/write overhead, simplifying firmware design for applications that store parameters externally or use RAM-based runtime configuration.
Does the R5F101PGAFB#30 support LIN bus communication?
Yes, the R5F101PGAFB#30 supports LIN bus communication through its UART peripheral, which includes LIN-break detection and synchronization field generation per LIN 2.x specifications. UART channels can be configured as LIN master or slave, enabling direct integration into automotive body electronics or industrial sub-networks without external transceivers.
What is the operating temperature range for the R5F101PGAFB#30?
The R5F101PGAFB#30 is rated for industrial operation from -40°C to +85°C (grade D), as indicated by the "D" suffix in its full ordering code structure. This makes it suitable for deployment in factory automation, smart grid infrastructure, and outdoor environmental monitoring equipment where extended thermal reliability is required.
Can the R5F101PGAFB#30 operate from a 1.8 V supply?
Yes, the R5F101PGAFB#30 supports a minimum supply voltage of 1.6 V, fully covering 1.8 V operation across its entire temperature range. Its I/O ports also support different-potential interfacing, allowing direct connection to 1.8 V logic devices without level shifters - critical for ultra-low-power sensor subsystems.
How many analog input channels does the R5F101PGAFB#30 provide?
The R5F101PGAFB#30 features a 10-bit A/D converter with up to 26 analog input channels, including dedicated pins for AVREFP/AVREFM and support for internal temperature sensor and 1.45 V reference voltage. This enables simultaneous monitoring of multiple sensors - such as thermistors, pressure transducers, and current shunts - within a single chip.
