Product details
Overview
R5F101BCANA#00 from Renesas is a 32-bit RL78/G13 microcontroller with 16 KB flash memory, 2 KB RAM, and no data flash, packaged in a 24-pin HWQFN (4 × 4 mm, 0.5-mm pitch). It operates from 1.6 V to 5.5 V, delivers 41 DMIPS at 32 MHz, and supports ultra-low-power modes including STOP (0.57 μA) and HALT, targeting battery-powered sensor nodes and industrial control interfaces.
For engineers reviewing the R5F101BCANA#00 datasheet, R5F101BCANA#00 pinout, R5F101BCANA#00 application, or R5F101BCANA#00 equivalent, key selection criteria include its 24-pin HWQFN footprint, absence of on-chip data flash, -40°C to +85°C industrial temperature grade (D), and integrated 10-bit ADC with up to 26 channels - critical for compact embedded sensing and actuation designs.
Technical Context
The R5F101BCANA#00 implements the RL78 CPU core with a 3-stage CISC 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). Its memory map spans 1 MB address space with 8 general-purpose register banks (8-bit × 8).
Peripheral integration includes one 12-bit interval timer, one real-time clock with calendar/alarm functions, eight 16-bit timers, three I²C/Simplified I²C channels, two UART/LIN channels, two CSI (SPI-compatible) channels, and an 8/10-bit A/D converter with internal 1.45 V reference and temperature sensor - all operating within the same 1.6–5.5 V supply range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Core Architecture | RL78 32-bit CISC CPU with 3-stage pipeline and 1 MB address space |

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F100BCANA#00 | Same package and pinout, but includes 4 KB data flash memory and 2 KB RAM (vs. R5F101BCANA#00's 2 KB RAM only) | Required where field firmware updates or parameter storage (e.g., calibration data) are needed | Select R5F100BCANA#00 if non-volatile parameter retention or background reprogramming is mandatory |
| R5F101BAANA#00 | 20-pin TSSOP variant (vs. 24-pin HWQFN); identical core, memory, and peripherals but fewer I/O (16 vs. 20 pins) | Suitable for space-constrained designs with reduced peripheral count and no need for >16 GPIO | Choose R5F101BAANA#00 when board area is critical and I/O count can be reduced by four lines |
Compared with R5F101BCANA#00, R5F100BCANA#00 adds data flash at the cost of higher unit price and identical power profile, while R5F101BAANA#00 trades four pins and HWQFN thermal performance for smaller footprint - enabling trade-offs between programmability, layout density, and thermal management.

FAQ
Does R5F101BCANA#00 include on-chip data flash memory?
No, R5F101BCANA#00 does not include data flash memory. It features 16 KB of code flash and 2 KB of RAM only. Data flash is present in the R5F100xx series (e.g., R5F100BCANA#00 offers 4 KB), but omitted in R5F101xx variants to reduce cost and die size for fixed-parameter firmware deployments.
What is the maximum operating frequency and corresponding performance of R5F101BCANA#00?
R5F101BCANA#00 operates up to 32 MHz with the high-speed on-chip oscillator, delivering 41 DMIPS. This performance level supports real-time tasks such as sensor fusion, motor control loops, and protocol stack processing without external acceleration.
Which package type and pin count does R5F101BCANA#00 use?
R5F101BCANA#00 uses a 24-pin HWQFN package (4 × 4 mm, 0.5-mm pitch), designated by the "ANA" suffix in the part number. This package supports thermal dissipation requirements for continuous operation in industrial ambient conditions.
What temperature grade is specified for R5F101BCANA#00?
R5F101BCANA#00 is rated for industrial operation from -40°C to +85°C (grade D), as confirmed by Renesas documentation. It is not qualified for the extended -40°C to +105°C (grade G) range used in higher-temperature industrial or under-hood automotive applications.
Can R5F101BCANA#00 operate from a single 1.8 V supply?
Yes, R5F101BCANA#00 supports operation from 1.6 V to 5.5 V, making it compatible with 1.8 V logic systems. At 1.8 V, the maximum operating frequency is reduced per the datasheet voltage-frequency curve, but full peripheral functionality including ADC and timers remains available.
