Product details
Overview
R5F100PJAFB#V0 from Renesas is a 100-pin LFQFP (0.5-mm pitch), industrial-grade RL78/G13 16-bit microcontroller with 256 KB flash, 8 KB data flash, 20 KB RAM, and integrated RTC, 10-bit ADC (26 channels), UART/LIN, I²C, CSI, and 16-bit timers. It operates from 1.6–5.5 V and delivers 41 DMIPS at 32 MHz for battery-powered industrial control and sensor interface applications.
For engineers reviewing the R5F100PJAFB#V0 datasheet, R5F100PJAFB#V0 pinout, R5F100PJAFB#V0 application, or R5F100PJAFB#V0 equivalent, key selection criteria include its -40°C to +105°C industrial temperature rating, on-chip LVD with 14-level interrupt/reset, background data flash rewriting (1M write cycles), and ultra-low-power STOP mode (0.57 μA) with RTC+LVD active.
Technical Context
The R5F100PJAFB#V0 implements the RL78 CPU core with 3-stage pipeline CISC architecture, supporting instruction execution times from 0.03125 μs (32 MHz high-speed oscillator) to 30.5 μs (32.768 kHz subsystem clock). Its memory subsystem includes 256 KB code flash (1 KB block size), 8 KB data flash with BGO support, and 20 KB SRAM - all accessible under single 1.6–5.5 V supply.
Peripherals are tightly integrated for deterministic real-time operation: dual DMA controller (4 channels), 16-bit timer array (16 channels), 12-bit interval timer, calendar RTC with alarm/correction, and multi-protocol serial interfaces including LIN-compliant UART, simplified I²C, and CSI (SPI-compatible). Power management includes HALT, STOP, and SNOOZE modes with dedicated low-speed oscillator for watchdog and RTC.

Its endurance is rated at 1,000,000 write/erase cycles (typical) with operation supported across the full supply voltage range of 1.8 V to 5.5 V. Background operation (BGO) allows program execution from code flash while rewriting data flash - a critical capability for reliable field firmware updates in the R5F100PJAFB#V0.
What power-saving modes does the R5F100PJAFB#V0 support, and what is its lowest current consumption?
The R5F100PJAFB#V0 supports HALT, STOP, and SNOOZE low-power modes. In STOP mode with only the real-time clock (RTC) and low-voltage detector (LVD) active, it consumes just 0.57 μA (typical) at VDD = 3.0 V and TA = 25°C. This ultra-low quiescent current enables multi-year battery operation in metering and remote sensing applications using the R5F100PJAFB#V0.
Is the R5F100PJAFB#V0 qualified for industrial temperature operation, and what is its specified range?
Yes, the R5F100PJAFB#V0 is qualified for industrial temperature operation with a specified ambient operating range of -40°C to +105°C. This "G" grade qualification is confirmed by Renesas' official ordering part number suffix and applies to the full device functionality, including flash programming, ADC accuracy, and timer operation - making the R5F100PJAFB#V0 suitable for under-hood automotive modules and factory-floor controllers.
How many analog input channels and what ADC resolution does the R5F100PJAFB#V0 provide?
The R5F100PJAFB#V0 features a 10-bit successive-approximation ADC with up to 26 configurable analog input channels. It supports internal reference voltages (1.45 V) and temperature sensing, and operates across the full supply range of 1.6 V to 5.5 V. This ADC capability is fully available in the R5F100PJAFB#V0's 100-pin LFQFP package, with dedicated ANI pins mapped to physical pins P20 through P27 and P30 through P37.
