Renesas R5F104BAANA#60

Overview

R5F104BAANA#60 from Renesas is a 32-pin HWQFN-packaged RL78/G14 16-bit microcontroller with 16 KB flash, 2.5 KB RAM, and ultra-low-power operation (66 μA/MHz active, 0.60 μA RTC+LVD mode) for battery-powered consumer and industrial control applications including sensor nodes and smart peripherals.

For engineers reviewing the R5F104BAANA#60 datasheet, R5F104BAANA#60 pinout, R5F104BAANA#60 application, or R5F104BAANA#60 equivalent, key selection criteria include its 32-pin 5×5 mm HWQFN package, 1.6–5.5 V supply range, integrated 10-bit ADC (8 channels), real-time clock with calendar, and support for LIN-bus UART communication in A-grade (-40 to +85°C) temperature range.

Technical Context

The R5F104BAANA#60 implements the RL78 CPU core with 3-stage pipeline, supporting instruction execution times from 0.03125 µs (32 MHz high-speed mode) to 30.5 µs (32.768 kHz ultra-low-speed mode), and includes multiply/divide/accumulate instructions. It integrates a 10-bit ADC with internal 1.45 V reference and temperature sensor.

Its peripheral set includes three UART/LIN channels, four I²C/simplified I²C interfaces, up to twelve 16-bit timers (including TAU, Timer RJ/RD/RG), one 12-bit interval timer, and a real-time clock with alarm and calendar functions-enabling time-stamped data logging and scheduled wake-up in low-power modes.

FAQ

What is the operating temperature range for the R5F104BAANA#60?

The R5F104BAANA#60 is rated for A-grade industrial/consumer operation from –40°C to +85°C. This specification is confirmed in the RL78/G14 datasheet Rev. 3.70 Section 1.1 under "Operating Ambient Temperature", where "A" denotes the –40 to +85°C range. The R5F104BAANA#60 does not support the extended G-grade (–40 to +105°C) variant.

Does the R5F104BAANA#60 include an integrated temperature sensor?

Yes, the R5F104BAANA#60 includes an on-chip temperature sensor usable with its 10-bit ADC. As documented in the RL78/G14 datasheet Rev. 3.70 Section 1.1, the A/D converter features "internal reference voltage (1.45 V) and temperature sensor". This sensor is accessible via dedicated ADC channel ANI19 (P120) and requires no external components for basic thermal monitoring in the R5F104BAANA#60.

What is the maximum clock frequency supported by the R5F104BAANA#60?

The R5F104BAANA#60 supports up to 32 MHz operation using its high-speed on-chip oscillator. Per RL78/G14 datasheet Rev. 3.70 Section 1.1, the high-speed oscillator offers selectable frequencies including 32 MHz with ±1.0% accuracy across 1.8–5.5 V and –20 to +85°C. The CPU achieves 44 DMIPS at this frequency, confirming full 32 MHz capability for the R5F104BAANA#60.

Can the R5F104BAANA#60 perform background data flash writes while executing code from main flash?

Yes, the R5F104BAANA#60 supports Background Operation (BGO) for data flash writes. As specified in the RL78/G14 datasheet Rev. 3.70 Section 1.1, "Instructions can be executed from the program memory while rewriting the data flash memory." This enables uninterrupted real-time processing during non-volatile parameter updates-a confirmed capability of the R5F104BAANA#60's 4 KB data flash subsystem.

Is the R5F104BAANA#60 pin-compatible with other RL78/G14 variants in the same 32-pin HWQFN package?

Yes, all RL78/G14 devices in the 32-pin HWQFN package-including R5F104BAANA#60, R5F104BCANA#60, and R5F104BDANA#60-share identical pin configuration and electrical characteristics. The RL78/G14 datasheet Rev. 3.70 Section 1.3.2 explicitly confirms uniform pinout across 32-pin HWQFN products, enabling direct substitution within the same memory-density family without PCB modification for the R5F104BAANA#60.
