Product details
Overview
R5F100PJAFB#10 from Renesas is a 100-pin LFQFP, 0.5-mm pitch, 192 KB flash, 8 KB data flash, 20 KB RAM RL78/G13 16-bit MCU operating from 1.6 V to 5.5 V, delivering 41 DMIPS at 32 MHz with ultra-low power consumption (66 μA/MHz active, 0.57 μA RTC+LVD mode), used in industrial control panels requiring long battery life and integrated analog sensing.
For engineers reviewing the R5F100PJAFB#10 datasheet, R5F100PJAFB#10 pinout, R5F100PJAFB#10 application, or R5F100PJAFB#10 equivalent, key selection criteria include its 100-pin LFQFP-0.5mm package, 192 KB code flash with self-programming and boot swap, 12-bit ADC with 26 channels, real-time clock with calendar/alarm, and industrial-grade -40°C to +105°C operation under G-grade qualification.
Technical Context
The R5F100PJAFB#10 implements the RL78 CPU core with CISC architecture and 3-stage pipeline, supporting instruction execution times from 0.03125 μs (32 MHz high-speed mode) to 30.5 μs (32.768 kHz subsystem clock). It integrates dual-clock domains: high-speed on-chip oscillator (±1.0% accuracy, selectable 1–32 MHz) and dedicated low-speed oscillator for watchdog and RTC.
Its peripheral set includes up to 16× 16-bit timers, 3× I²C/Simplified I²C channels, 2× UART/LIN interfaces, 2× CSI (SPI-compatible) channels, DMA controller with 4 channels, and hardware multiplier/divider/accumulator - all optimized for deterministic real-time response in resource-constrained embedded systems.

The R5F100PJAFB#10 operates at up to 32 MHz with an RL78 CPU core delivering 41 DMIPS. This performance level is achieved using the high-speed on-chip oscillator, which maintains ±1.0% accuracy across 1.8–5.5 V and -40°C to +105°C - making it suitable for deterministic real-time tasks in industrial environments without external crystal dependency.
Does the R5F100PJAFB#10 support in-system programming and secure firmware updates?
Yes, the R5F100PJAFB#10 supports full in-system programming via on-chip debug interface and includes flash shield window functionality. This allows selective locking of flash regions during firmware updates, preventing unauthorized access to protected code sections while enabling safe field upgrades - a key requirement for certified industrial devices using R5F100PJAFB#10.
What analog features does the R5F100PJAFB#10 integrate for sensor interfacing?
The R5F100PJAFB#10 integrates a 10-bit A/D converter with up to 26 input channels, internal 1.45 V reference voltage, and an on-chip temperature sensor (active in HS mode). These features allow direct connection of thermistors, potentiometers, current-sense amplifiers, and other analog sensors - eliminating external signal-conditioning components in many R5F100PJAFB#10-based designs.
Is the R5F100PJAFB#10 qualified for industrial temperature range operation?
Yes, the R5F100PJAFB#10 carries the 'G' grade designation, certifying operation from -40°C to +105°C ambient temperature. This qualification aligns with industrial control cabinet and outdoor equipment requirements, and is validated across all specified electrical parameters including flash endurance, ADC linearity, and oscillator stability - ensuring reliable R5F100PJAFB#10 deployment in harsh thermal environments.
How does the R5F100PJAFB#10 manage ultra-low power consumption in battery-operated applications?
The R5F100PJAFB#10 achieves 0.57 μA in STOP mode with RTC and LVD active, and 66 μA/MHz in active mode. Its SNOOZE mode allows peripheral-triggered wake-up without full CPU restart, while HALT mode retains register context at ~1.2 μA. These capabilities make R5F100PJAFB#10 ideal for energy-harvesting or coin-cell-powered nodes where multi-year operation is mandatory.
