Product details
Overview
R5F101SJAFB#30 from Renesas is a 32-bit RL78/G13 microcontroller with no data flash memory, housed in a 100-pin LFQFP (0.5-mm pitch) package, operating from 1.6 V to 5.5 V, delivering 41 DMIPS at 32 MHz and featuring ultra-low-power operation (66 μA/MHz active, 0.57 μA RTC+LVD mode) for battery-powered industrial control and sensor interface applications.
For engineers reviewing the R5F101SJAFB#30 datasheet, R5F101SJAFB#30 pinout, R5F101SJAFB#30 application, or R5F101SJAFB#30 equivalent, key selection criteria include its 128 KB code flash, 8 KB RAM, 26-channel 10-bit ADC, real-time clock with calendar, and support for LIN-bus UART - all within an industrial-grade -40°C to +105°C temperature range.
Technical Context
The R5F101SJAFB#30 implements the RL78 CPU core with CISC architecture and 3-stage pipeline, supporting variable instruction execution time 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, watchdog timer with dedicated low-speed oscillator, and background operation for flash programming.
Its peripheral set includes up to 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 on-chip SFRs without external glue logic. The device uses a single power supply and supports HALT, STOP, and SNOOZE low-power modes.

The R5F101SJAFB#30 uses a 100-pin LFQFP package with 0.5-mm pitch (RENESAS Code PLQP0100KE-A), as confirmed in Table 1-1 (Page 12) of the R01DS0131EJ0380 datasheet. The "FB" suffix in the part number explicitly denotes LFQFP, and "#30" indicates tray packaging.
What is the operating temperature range for the R5F101SJAFB#30?
The R5F101SJAFB#30 is rated for industrial operation from -40°C to +105°C (G-grade), as indicated by the "G" in its family designation and confirmed in Section 1.1 "Operating ambient temperature" of R01DS0131EJ0380. This qualifies it for under-hood automotive, factory floor, and outdoor infrastructure applications.
Which serial communication interfaces are supported by the R5F101SJAFB#30?
The R5F101SJAFB#30 supports three hardware serial interface types: up to 4 UART/LIN channels (with full LIN 2.2 compliance), up to 10 I²C/Simplified I²C channels (SMBus compatible), and up to 8 CSI (SPI-compatible) channels - all detailed in Section 1.1 "Serial interface" of R01DS0131EJ0380.
