Product details
Overview
R5F101PJAFB#10 from Renesas is a 100-pin LFQFP-0.5mm, 32-bit RL78/G13 microcontroller with 64 KB flash, 4 KB RAM, no data flash, and industrial-grade operation (−40°C to +85°C). It delivers 41 DMIPS at 32 MHz, consumes 66 μA/MHz active and 0.57 μA in RTC+LVD-only mode, and integrates 16-bit timers, 10-bit ADC (16 channels), UART/LIN, I²C, and CSI interfaces for embedded control.
For engineers reviewing the R5F101PJAFB#10 datasheet, R5F101PJAFB#10 pinout, R5F101PJAFB#10 application, or R5F101PJAFB#10 equivalent, key selection criteria include its 100-pin LFQFP package, absence of data flash memory, −40°C to +85°C industrial temperature rating, integrated LIN-capable UART, and support for low-power STOP/HALT/SNOOZE modes in resource-constrained systems.
Technical Context
The R5F101PJAFB#10 implements the RL78 CPU core-a CISC architecture with 3-stage pipeline-enabling instruction execution times from 0.03125 μs (32 MHz high-speed mode) to 30.5 μs (32.768 kHz ultra-low-speed mode). It supports single-supply operation from 1.6 V to 5.5 V and includes on-chip power-on-reset (POR) and voltage detector (LVD) with 14 selectable levels.
Its peripheral set includes up to 16 channels of 16-bit timer, one 12-bit interval timer, one real-time clock with calendar/alarm functions, one watchdog timer, and a 10-bit A/D converter with internal reference (1.45 V) and temperature sensor. DMA controller supports 4 channels with 2-clock transfers between SFR and RAM.

FAQ
What is the maximum operating frequency and corresponding performance of the R5F101PJAFB#10?
The R5F101PJAFB#10 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 +85°C industrial temperature grade, making it suitable for deterministic real-time control tasks such as motor commutation and sensor fusion.
Does the R5F101PJAFB#10 include data flash memory?
No, the R5F101PJAFB#10 does not include data flash memory. Per Renesas part numbering convention, the "101" prefix indicates no data flash, distinguishing it from "100" variants (e.g., R5F100PJAFB#10) which integrate 4 KB of data flash. All non-volatile storage for the R5F101PJAFB#10 must be implemented in code flash using self-programming features, with appropriate wear-leveling and sector management in firmware.
What communication interfaces are supported by the R5F101PJAFB#10?
The R5F101PJAFB#10 supports multiple serial interfaces: up to 4 UART channels (with LIN bus support), up to 10 I²C/Simplified I²C channels, and up to 8 CSI (Simplified SPI) channels. Pin multiplexing allows shared use of pins-for example, P11 serves as SI00 (SPI input), RxD0 (UART receive), TOOLRxD (debug), and SDA00 (I²C data)-enabling flexible board design without additional level shifters or bus expanders.
What low-power modes are available on the R5F101PJAFB#10, and what is the lowest current draw?
The R5F101PJAFB#10 supports HALT, STOP, and SNOOZE low-power modes. In STOP mode with only RTC and LVD active, it draws just 0.57 μA-verified at VDD = 1.8–5.5 V and TA = −40°C to +85°C. This enables multi-year operation on coin-cell batteries in sensor nodes and metering applications. Wake-up sources include external interrupts, RTC alarm, and LVD threshold detection.
Is the R5F101PJAFB#10 pin-compatible with other RL78/G13 devices in the same package?
Yes, the R5F101PJAFB#10 is pin-compatible with all other RL78/G13 100-pin LFQFP variants-including R5F100PJAFB#10 and R5F101PJAFB#30-because they share identical pin configuration, electrical characteristics, and peripheral mapping per the RL78/G13 family datasheet. This allows hardware reuse across firmware variants with different memory or packaging requirements.
