Product details
Overview
R5F104BAAFP#70 from Renesas is a 32-pin LQFP-packaged RL78/G14 16-bit microcontroller with 16 KB flash, 2.5 KB RAM, and 4 KB data flash, operating at 1.6–5.5 V. It delivers 44 DMIPS at 32 MHz, features ultra-low-power HALT/STOP/SNOOZE modes (66 μA/MHz active, 0.60 μA RTC+LVD), and integrates 8-channel 10-bit ADC, UART/I²C/CSI interfaces, and real-time clock - deployed in battery-powered industrial sensors and smart metering endpoints.
For engineers reviewing the R5F104BAAFP#70 datasheet, R5F104BAAFP#70 pinout, R5F104BAAFP#70 application, or R5F104BAAFP#70 equivalent, key selection criteria include its 32-pin LQFP-0.8 mm pitch package, 16 KB code flash with self-programming support, 10-bit ADC with internal reference, and -40°C to +85°C industrial temperature grade (A-field).
Technical Context
The RL78/G14 core implements a CISC architecture with 3-stage pipeline and configurable instruction timing (0.03125 µs @32 MHz to 30.5 µs @32.768 kHz). It supports multiply/divide/accumulate instructions and 1 MB address space across four register banks.
Peripherals include Timer Array Unit (TAU) with 4 channels, 12-bit interval timer, RTC with calendar/alarm, watchdog timer, and Event Link Controller (ELC) enabling hardware-triggered peripheral chaining without CPU intervention - optimizing deterministic low-latency response in real-time control loops.

FAQ
What is the maximum operating frequency and corresponding performance of the R5F104BAAFP#70?
The R5F104BAAFP#70 operates up to 32 MHz, delivering 44 DMIPS of processing performance. This speed is achieved using the high-speed on-chip oscillator with ±1.0% accuracy across 1.8–5.5 V and -20°C to +85°C. The RL78/G14 core's 3-stage pipeline and optimized instruction set enable deterministic execution for real-time control tasks in the R5F104BAAFP#70.
Does the R5F104BAAFP#70 support in-system programming and secure firmware updates?
Yes, the R5F104BAAFP#70 supports self-programming of both code and data flash memory with boot swapping and flash shield window protection. Its on-chip debug function enables standard SWD/JTAG programming, and block erase prohibition prevents unauthorized modification - critical for secure firmware updates in the R5F104BAAFP#70.
What analog peripherals are integrated into the R5F104BAAFP#70?
The R5F104BAAFP#70 integrates an 8-channel, 10-bit successive approximation ADC with selectable internal 1.45 V reference voltage and built-in temperature sensor. It also includes a 2-channel comparator with window mode and high/low-speed operation - all usable without external components, reducing BOM cost in the R5F104BAAFP#70 design.
How does the R5F104BAAFP#70 achieve ultra-low power consumption in STOP mode?
The R5F104BAAFP#70 achieves 0.60 μA typical current in STOP mode by retaining only the real-time clock (RTC) and low-voltage detector (LVD) circuits while halting the CPU, flash, and most peripherals. The internal regulator remains active with REGC capacitor stabilization, enabling fast wake-up (<10 µs) - a key feature distinguishing the R5F104BAAFP#70 in battery-critical applications.
Is the R5F104BAAFP#70 pin-compatible with other RL78/G14 variants in the same package?
Yes, all RL78/G14 devices in the 32-pin LQFP package (e.g., R5F104BAx, R5F104BCx, R5F104BDx) share identical pinouts and electrical characteristics. This allows direct substitution between memory variants (16 KB → 32 KB → 48 KB) without PCB changes - a verified compatibility confirmed across Renesas' RL78/G14 documentation for the R5F104BAAFP#70 family.
