Product details
Overview
R5F104JEDFA#V0 from Renesas is a 52-pin LQFP-0.65 mm pitch, industrial-grade (D-class) 16-bit RL78/G14 microcontroller with 64 KB flash, 4 KB data flash, and 5.5 KB RAM. It delivers 44 DMIPS at 32 MHz, operates from 1.6–5.5 V, achieves 66 μA/MHz active current and 0.60 μA RTC+LVD standby, and targets battery-powered industrial sensor nodes and low-power HMI control.
For engineers reviewing the R5F104JEDFA#V0 datasheet, R5F104JEDFA#V0 pinout, R5F104JEDFA#V0 application, or R5F104JEDFA#V0 equivalent, key selection criteria include its 52-pin LQFP package with full peripheral remapping, integrated RTC + LVD for fail-safe operation, and support for LIN-bus UART channels in harsh ambient conditions (−40 to +85°C).
Technical Context
The R5F104JEDFA#V0 implements the RL78 CPU core with 3-stage pipeline CISC architecture, supporting instruction execution times from 0.03125 μs (32 MHz high-speed mode) to 30.5 μs (32.768 kHz ultra-low-power mode). It integrates a 12-bit interval timer, real-time clock with calendar/alarm, and watchdog timer driven by dedicated low-speed oscillator.
Peripheral subsystems include up to 12-channel 16-bit Timer Array Unit (TAU), 8–20-channel 10-bit A/D converter with internal 1.45 V reference and temperature sensor, two 8-bit D/A outputs, and configurable serial interfaces: 3–4 UART/LIN channels, 4–10 I²C/Simplified I²C channels, and 3–8 CSI (SPI-compatible) channels-all accessible via Event Link Controller (ELC) for hardware-triggered, low-CPU-overhead operation.

Does the R5F104JEDFA#V0 support hardware debugging, and how is it implemented?
Yes, the R5F104JEDFA#V0 includes an on-chip debug function accessible via dedicated P50 (TOOLRxD) and P51 (TOOLTxD) pins. This enables full-featured debugging-including breakpoints, watchpoints, and real-time trace-without external JTAG adapters. The R5F104JEDFA#V0 uses these pins for both programming and runtime analysis, simplifying development and field diagnostics.
How does the R5F104JEDFA#V0 manage power in battery-critical applications?
The R5F104JEDFA#V0 supports multiple low-power states: HALT mode draws just 66 μA/MHz, STOP mode consumes only 0.60 μA (RTC + LVD active), and SNOOZE mode enables selective peripheral wake-up. Combined with voltage detector (LVD) interrupt capability and 1.6–5.5 V operation, the R5F104JEDFA#V0 ensures robust, multi-year operation in energy-constrained systems.
Can the R5F104JEDFA#V0 interface directly with 1.8 V or 3.3 V peripherals?
Yes, the R5F104JEDFA#V0 supports different potential interface capability: its I/O ports can safely connect to 1.8 V, 2.5 V, or 3.3 V devices without external level shifters. Input thresholds and drive strength are configured per port, and the R5F104JEDFA#V0 maintains full functionality across its 1.6–5.5 V supply range-simplifying mixed-voltage system design.
What serial communication protocols are supported by the R5F104JEDFA#V0?
