Product details
Overview
R5F104PFDFB#V0 from Renesas is a 100-pin LFQFP, 0.5 mm pitch, industrial-grade (G) 16-bit RL78/G14 microcontroller with 96 KB flash, 12 KB RAM, and 8 KB data flash. It operates from 1.6–5.5 V, delivers 44 DMIPS at 32 MHz, and supports ultra-low-power modes (0.60 μA RTC+LVD). Used in battery-powered industrial sensors and motor control interfaces.
For engineers reviewing the R5F104PFDFB#V0 datasheet, R5F104PFDFB#V0 pinout, R5F104PFDFB#V0 application, or R5F104PFDFB#V0 equivalent, key selection criteria include its 100-pin LFQFP-0.5 mm package, -40°C to +105°C industrial temperature rating, integrated 10-bit ADC (20 channels), dual UART/LIN support, and hardware DTC/ELC for deterministic real-time peripheral coordination.
Technical Context
The R5F104PFDFB#V0 implements the RL78 CPU core with 3-stage pipeline CISC architecture, supporting instruction execution times from 0.03125 μs (32 MHz) to 30.5 μs (32.768 kHz). It integrates a configurable Event Link Controller (ELC) that routes 26 event sources directly to peripherals without CPU intervention.
Its power management includes HALT, STOP, and SNOOZE modes, with dedicated low-speed on-chip oscillator for watchdog operation and ±1.0% accuracy high-speed oscillator (1–64 MHz selectable). The device features background operation (BGO) for data flash rewriting while executing code from program memory.

FAQ
What is the maximum operating temperature range certified for the R5F104PFDFB#V0?
The R5F104PFDFB#V0 is rated for industrial applications with guaranteed operation from -40°C to +105°C. This G-grade qualification ensures reliability in harsh environments such as factory automation cabinets, outdoor utility meters, and motor drive enclosures where ambient temperatures exceed standard commercial limits.
Does the R5F104PFDFB#V0 support hardware-based cryptographic acceleration?
No, the R5F104PFDFB#V0 does not include dedicated cryptographic accelerators. It relies on software libraries for AES, SHA, or RSA operations. For hardware crypto, consider Renesas RA-family MCUs. However, R5F104PFDFB#V0 does provide flash shield window and block erase prohibition for basic firmware IP protection.
Can the R5F104PFDFB#V0's data flash be rewritten while the CPU executes from main flash memory?
Yes, the R5F104PFDFB#V0 supports Background Operation (BGO) for data flash. Code execution continues from program memory during data flash erase/write cycles, enabling uninterrupted real-time control while logging sensor data or updating configuration parameters.
What debug interface does the R5F104PFDFB#V0 use, and is JTAG supported?
The R5F104PFDFB#V0 uses Renesas' on-chip debug interface via dedicated pins P40 (TOOL0) and P50/P51 (TRJIO0/TRJO0), compatible with E2 emulator and E2 studio. It does not support IEEE 1149.1 JTAG; instead, it implements SWD-like single-wire debug (SWD) with optional trace capability through the on-chip debug module.
How many UART channels with LIN physical layer compliance does the R5F104PFDFB#V0 integrate?
The R5F104PFDFB#V0 integrates three UART channels, each capable of LIN 2.2/2.3 physical layer compliance via programmable break detection, sync field handling, and checksum generation - enabling direct connection to LIN transceivers without external protocol assist chips.
