Product details
Overview
R5F104BAAFP#X0 from Renesas is a 32-pin LQFP-32, 1.8–5.5 V RL78/G14 16-bit microcontroller with 16 KB flash, 2.5 KB RAM, 48 DMIPS at 32 MHz, and ultra-low-power operation (66 μA/MHz active, 0.60 μA RTC+LVD mode), designed for battery-powered industrial sensors and smart metering interfaces.
For engineers reviewing the R5F104BAAFP#X0 datasheet, R5F104BAAFP#X0 pinout, R5F104BAAFP#X0 application, or R5F104BAAFP#X0 equivalent, key selection criteria include its 32-pin LQFP-0.8 mm pitch package, 16 KB code flash with data flash shield window, integrated RTC + LVD, and support for LIN-bus UART and hardware DTC for sensor data aggregation.
Technical Context
The R5F104BAAFP#X0 implements the RL78 CPU core with 3-stage pipeline, supporting instruction execution times from 0.03125 μs (32 MHz) to 30.5 μs (32.768 kHz), and includes multiply/divide/accumulate instructions within a 1 MB address space. It integrates a 12-bit interval timer, real-time clock with calendar/alarm, and watchdog timer with dedicated low-speed oscillator.
Peripheral integration includes 8-channel 10-bit A/D converter (1.45 V internal reference, temperature sensor), up to two 8-bit D/A channels, two comparators, and serial interfaces: 3–4 UART/LIN channels, 3–8 CSI (SPI-compatible), and 4–10 I²C channels - all configurable via peripheral I/O redirection registers (PIOR0/1).

FAQ
What is the maximum operating frequency and corresponding performance of the R5F104BAAFP#X0?
The R5F104BAAFP#X0 operates up to 32 MHz with a measured performance of 48 DMIPS. Its high-accuracy on-chip oscillator maintains ±1.0% tolerance across 1.8–5.5 V and -20 to +85°C, eliminating need for external crystal in many timing-critical applications. The RL78 core achieves this with a 3-stage pipeline and optimized instruction set including multiply/divide operations.
Does the R5F104BAAFP#X0 support LIN bus communication, and how is it implemented?
Yes, the R5F104BAAFP#X0 supports LIN bus communication through its UART peripherals-specifically UART0 and UART2-which include LIN-break-detection and sync-field generation features per LIN 2.2A specification. The R5F104BAAFP#X0 requires no external transceiver for basic LIN node operation when paired with a compliant driver IC, and its ELC enables automatic response triggering upon frame reception.
What are the memory configuration and programming capabilities of the R5F104BAAFP#X0?
The R5F104BAAFP#X0 integrates 16 KB of code flash memory (1 KB erase blocks), 4 KB of data flash memory, and 2.5 KB of on-chip RAM. It supports self-programming with boot-swap and flash-shield-window functions, enabling secure firmware updates. Background operation (BGO) allows code execution from flash while rewriting data flash, with 1,000,000 write cycles rated at VDD = 1.8–5.5 V.
How does the R5F104BAAFP#X0 achieve ultra-low power consumption in STOP mode?
The R5F104BAAFP#X0 achieves 0.60 μA STOP mode current by retaining only the real-time clock (RTC) and low-voltage detector (LVD) circuits in active state while shutting down CPU, flash, RAM, and most peripherals. This mode supports wake-up via RTC alarm, LVD threshold breach, or external interrupt (e.g., INT0–INT7), making it ideal for infrequent-event sensing applications like utility meter tamper detection.
Is the R5F104BAAFP#X0 pin-compatible with other RL78/G14 variants in the same package?
Yes, all RL78/G14 devices in the 32-pin LQFP-0.8 mm pitch package-including R5F104BAAFP#X0, R5F104BCAFP#X0, and R5F104BDAFP#X0-share identical pinouts and electrical characteristics. Memory size (16 KB vs. 32 KB vs. 48 KB) and peripheral enablement differ per variant, but PCB layout and signal routing remain fully interchangeable across this pin-count family.
