Product details
Overview
R5F101BCANA#20 from Renesas is a 32-bit RL78/G13 microcontroller with 16 KB flash memory, 2 KB RAM, and no data flash, housed in a 32-pin HWQFN (5 × 5 mm, 0.5-mm pitch) package. It delivers 41 DMIPS at 32 MHz, operates from 1.6 V to 5.5 V, 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#20 datasheet, R5F101BCANA#20 pinout, R5F101BCANA#20 application, or R5F101BCANA#20 equivalent, key selection criteria include its 32-pin HWQFN footprint, absence of on-chip data flash, -40°C to +85°C industrial temperature grade (D), and integrated 10-bit ADC with 12-channel analog input capability.
Technical Context
The R5F101BCANA#20 implements the RL78 CPU core with CISC architecture and 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). Its memory map spans 1 MB address space with banked 8-bit general-purpose registers.
It integrates peripheral subsystems including up to 16 channels of 16-bit timers, one real-time clock with calendar/alarm functions, two UART/LIN channels, three I²C interfaces, and an 8/10-bit A/D converter with internal 1.45 V reference and temperature sensor - all configurable under single-supply operation from 1.6 V to 5.5 V.

FAQ
What is the operating temperature range for R5F101BCANA#20?
The R5F101BCANA#20 is rated for industrial operation from -40°C to +85°C (grade D), as confirmed in the RL78/G13 datasheet revision 3.80. This rating applies across the full 1.6 V to 5.5 V supply range and supports deployment in harsh environments such as factory floors or outdoor enclosures without additional thermal derating.
Does R5F101BCANA#20 include data flash memory?
No, the R5F101BCANA#20 does not include data flash memory. The '101' in the part number explicitly indicates "data flash not provided", per Renesas' part numbering convention. Only code flash (16 KB) and RAM (2 KB) are present; persistent parameter storage requires external EEPROM or FRAM.
Which development tools support R5F101BCANA#20?
R5F101BCANA#20 is fully supported by Renesas e² studio IDE, CS+ for CC, and the E2 emulator Lite. Hardware debugging uses the 6-pin FINE interface (VDD, VSS, RESET, TMS, TDI, TDO), compatible with standard RL78 debug probes - no special adapter is needed for evaluation or production programming.
Can R5F101BCANA#20 operate from a single 3.3 V supply?
Yes, R5F101BCANA#20 operates reliably from 3.3 V (within its 1.6 V–5.5 V range). All I/Os are 5 V-tolerant when configured as inputs, and the internal voltage regulator ensures stable core voltage. No level-shifting is required for interfacing with 3.3 V peripherals like sensors or displays.
What packaging and reel specifications apply to R5F101BCANA#20?
R5F101BCANA#20 ships in embossed tape (HWQFN) format per the '#20' suffix, with 3,000 units per reel. The package is PWQN0032KE-A (5 × 5 mm, 0.5-mm pitch), moisture sensitivity level MSL3, and complies with JEDEC J-STD-020D reflow profile requirements.
