Overview
R5F104JDAFA#10 from Renesas is a 52-pin LQFP-0.65 mm pitch, industrial-grade (D) 16-bit RL78/G14 microcontroller with 96 KB flash, 12 KB RAM, and 8 KB data flash. It delivers 44 DMIPS at 32 MHz, operates from 1.6–5.5 V, and supports ultra-low-power modes (66 μA/MHz active, 0.60 μA RTC+LVD). It targets battery-powered industrial sensor nodes requiring integrated analog peripherals and LIN-capable UART.
For engineers reviewing the R5F104JDAFA#10 datasheet, R5F104JDAFA#10 pinout, R5F104JDAFA#10 application, or R5F104JDAFA#10 equivalent, key selection criteria include its 52-pin LQFP package, 96 KB/12 KB/8 KB memory configuration, -40 to +85°C industrial temperature rating, and support for hardware-accelerated data transfer via DTC and event-driven peripheral control via ELC.
Technical Context
The R5F104JDAFA#10 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 watchdog timer with dedicated low-speed oscillator.
Peripheral integration includes up to 20-channel 8/10-bit ADC with internal 1.45 V reference and temperature sensor, two 8-bit DAC channels, up to 12× 16-bit timers (TAU, RJ, RD, RG), 3–4 UART/LIN channels, 4–10 I²C interfaces, and 3–8 CSI (SPI-compatible) channels - all accessible through flexible I/O redirection registers.

FAQ
What is the maximum operating frequency and corresponding performance of the R5F104JDAFA#10?
The R5F104JDAFA#10 operates at up to 32 MHz with a peak performance of 44 DMIPS. Its high-accuracy on-chip oscillator maintains ±1.0% frequency stability across 1.8–5.5 V supply and -20 to +85°C ambient, eliminating need for external crystal in many timing-tolerant applications. This allows the R5F104JDAFA#10 to drive real-time control loops and communication stacks without external timing components.
Does the R5F104JDAFA#10 support LIN bus communication, and how is it implemented?
Yes, the R5F104JDAFA#10 supports LIN 2.x protocol natively through its UART peripherals, which include hardware sync-break detection, checksum generation, and identifier filtering. No external LIN transceiver is required for basic slave-node functionality. The R5F104JDAFA#10's UART modules can be configured for LIN mode via control registers, enabling direct connection to LIN bus wiring with only passive termination resistors.
What are the memory resources allocated to the R5F104JDAFA#10, and how is data flash endurance specified?
The R5F104JDAFA#10 integrates 96 KB of code flash memory (organized in 1 KB blocks), 12 KB of on-chip RAM, and 8 KB of data flash memory. Data flash supports background operation (BGO) and guarantees 1,000,000 write/erase cycles (typical) at VDD = 1.8–5.5 V - sufficient for daily firmware update logging or decade-long energy meter data retention. The R5F104JDAFA#10 also supports flash shield window and block erase prohibition for security-critical applications.
How does the R5F104JDAFA#10 achieve ultra-low power consumption, and what are the lowest current modes?
The R5F104JDAFA#10 achieves ultra-low power via multiple hardware-controlled sleep modes: HALT (CPU stopped, peripherals active), STOP (all clocks halted except RTC/LVD), and SNOOZE (selected peripherals active while CPU sleeps). In STOP mode with only RTC and LVD enabled, it draws just 0.60 μA at 25°C - verified per datasheet R01DS0053EJ0370. This enables multi-year battery life in intermittent-sensing applications, and the R5F104JDAFA#10 retains full SRAM content and register state across all low-power modes.
What debug and programming interfaces are supported by the R5F104JDAFA#10?
The R5F104JDAFA#10 supports single-wire debug (SWD) via the TOOL0 pin (P40) and TRJIO0/TRJO0 pins (P01/P00), enabling full JTAG-equivalent debugging including breakpoints, watchpoints, and real-time memory inspection. It also supports on-chip self-programming with boot swapping and flash shield window protection. Programming is performed via Renesas Flash Programmer or compatible tools using the same SWD interface - no external programmer hardware is required for development or field updates. The R5F104JDAFA#10 includes built-in ROM-based bootloader for factory or field firmware recovery.
