Product details
Overview
R5F104PJGFB#30 from Renesas is a 48-pin LFQFP, 0.5 mm pitch, industrial-grade (−40°C to +105°C) RL78/G14 16-bit MCU with 192 KB flash, 8 KB data flash, 20 KB RAM, and integrated RTC, 10-bit ADC (16 channels), UART/SPI/I²C interfaces, and ultra-low-power operation (66 μA/MHz active, 0.60 μA in RTC+LVD mode). It targets battery-powered industrial sensors and smart metering systems requiring long runtime and robust timing.
For engineers reviewing the R5F104PJGFB#30 datasheet, R5F104PJGFB#30 pinout, R5F104PJGFB#30 application, or R5F104PJGFB#30 equivalent, key selection criteria include its 192 KB code flash capacity, 48-pin LFQFP-0.5 mm package, −40°C to +105°C industrial temperature rating, integrated 10-bit ADC with 16 analog inputs, and support for SNOOZE mode with background data flash rewriting.
Technical Context
The R5F104PJGFB#30 implements the RL78 CPU core with CISC architecture, 3-stage pipeline, and configurable instruction timing (0.03125 µs @ 32 MHz to 30.5 µs @ 32.768 kHz). It integrates a 12-bit interval timer, real-time clock with calendar/alarm, and Event Link Controller (ELC) enabling hardware-triggered peripheral chaining without CPU intervention.
Its power management includes HALT, STOP, and SNOOZE modes, with on-chip LVD (14 selectable voltage thresholds) and POR. The DTC supports block/chain transfers activated by interrupts, while the high-accuracy ±1.0% on-chip oscillator (1–64 MHz) eliminates external crystal dependency for many applications.

FAQ
What is the maximum operating frequency and corresponding performance of the R5F104PJGFB#30?
The R5F104PJGFB#30 operates at up to 32 MHz with a high-speed on-chip oscillator, delivering 44 DMIPS of processing performance. Its RL78 CPU core supports configurable instruction timing-from 0.03125 µs per instruction at 32 MHz down to 30.5 µs at 32.768 kHz-enabling dynamic trade-offs between speed and ultra-low-power operation in the R5F104PJGFB#30.
Does the R5F104PJGFB#30 support in-system programming and secure firmware updates?
Yes, the R5F104PJGFB#30 supports full in-system programming via on-chip debug interface and includes flash shield window protection, block erase prohibition, and boot swapping functionality. These features enable secure field firmware updates and prevent unauthorized code access-critical for certified smart metering and industrial control deployments using the R5F104PJGFB#30.
How many analog input channels does the R5F104PJGFB#30 provide, and what ADC resolution is supported?
The R5F104PJGFB#30 integrates a 10-bit successive approximation register (SAR) ADC with up to 16 analog input channels (ANI0–ANI19, excluding reserved pins). It supports internal 1.45 V reference voltage and on-die temperature sensing, enabling precise ratiometric measurements and thermal monitoring without external components in the R5F104PJGFB#30.
What serial communication interfaces are available on the R5F104PJGFB#30?
The R5F104PJGFB#30 provides three UART channels (one supporting LIN bus), up to ten I²C/simplified I²C channels, and three to eight CSI (SPI-compatible) channels. All interfaces are software-configurable and supported by the Event Link Controller for hardware-triggered transfers-enhancing deterministic communication in real-time control applications built around the R5F104PJGFB#30.
Is an external crystal required for real-time clock operation in the R5F104PJGFB#30?
No-an external 32.768 kHz crystal is optional. The R5F104PJGFB#30 includes a calibrated low-speed on-chip oscillator for RTC operation, achieving sufficient accuracy for non-critical timekeeping. However, for calendar-grade precision (e.g., billing in smart meters), connecting a 32.768 kHz crystal to P121/P122 is recommended-and fully supported by the R5F104PJGFB#30's RTC module.
