Product details
Overview
R5F104PJAFA#X0 from Renesas is a 100-pin LQFP-0.65 mm pitch, industrial-grade (TA = −40 to +85°C) RL78/G14 16-bit MCU with 256 KB flash, 8 KB data flash, 24 KB RAM, 52-channel I/O, and integrated RTC, 12-bit ADC (20 channels), dual 8-bit DAC, and UART/I²C/CSI interfaces. It targets battery-powered industrial control and sensor interface applications requiring ultra-low power (66 μA/MHz active, 0.60 μA RTC+LVD mode).
For engineers reviewing the R5F104PJAFA#X0 datasheet, R5F104PJAFA#X0 pinout, R5F104PJAFA#X0 application, or R5F104PJAFA#X0 equivalent, key selection considerations include its 100-pin LQFP package, 256 KB flash capacity, support for background data flash rewriting (BGO), real-time clock calendar function, and compatibility with Renesas' RL78 toolchain and E2 studio IDE.
Technical Context
The R5F104PJAFA#X0 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 Data Transfer Controller (DTC) for autonomous memory transfers triggered by interrupts and an Event Link Controller (ELC) enabling hardware-triggered peripheral chaining without CPU intervention.
Its analog subsystem includes a 12-bit interval timer, 12-bit A/D converter with internal 1.45 V reference and temperature sensor, two 8-bit D/A converters with real-time output capability, and up to two comparators with selectable internal/external reference voltage. Power management features HALT, STOP, and SNOOZE modes plus on-chip LVD with 14-level interrupt/reset selection.

FAQ
What is the maximum operating frequency and corresponding power consumption of the R5F104PJAFA#X0?
The R5F104PJAFA#X0 operates at up to 32 MHz with a typical active current of 66 μA per MHz. At full speed, this yields approximately 2.1 mA total active current (VDD = 3.3 V, TA = 25°C), verified in the RL78/G14 electrical characteristics table. Its ultra-low-power STOP mode draws only 0.60 μA when RTC and LVD remain active-critical for long-life battery applications.
Does the R5F104PJAFA#X0 support in-system programming and secure firmware updates?
Yes, the R5F104PJAFA#X0 supports full in-system programming via its on-chip debug interface and includes flash shield window and block erase prohibition features for IP protection. Self-programming with boot swap functionality allows atomic firmware updates-ensuring the R5F104PJAFA#X0 remains operational even during partial write failures.
How many serial communication interfaces does the R5F104PJAFA#X0 integrate, and what protocols are supported?
The R5F104PJAFA#X0 integrates up to four UART channels (with LIN-bus support), ten I²C/simplified I²C channels, and eight CSI (SPI-compatible) channels. These are distributed across multiple pin groups and configurable via peripheral I/O redirection registers-enabling concurrent communication with sensors, displays, and host controllers without external bus expanders.
Can the R5F104PJAFA#X0 operate from a single 1.8 V supply, and what peripherals remain functional at that voltage?
Yes, the R5F104PJAFA#X0 supports operation from 1.6 V to 5.5 V, including stable 1.8 V operation. At 1.8 V, all core functions-including 32 MHz operation (via high-speed on-chip oscillator), 12-bit ADC (with internal 1.45 V reference), RTC, and all serial interfaces-remain fully functional per the RL78/G14 DC characteristics table.
What development tools and software support are available for the R5F104PJAFA#X0?
Renesas provides full toolchain support for the R5F104PJAFA#X0, including E2 emulator hardware, CS+ IDE, e² studio (Eclipse-based), and the RL78/G14-specific Firmware Integration Technology (FIT) modules.
