Product details
Overview
R5F100BAANA#40 from Renesas is a 32-pin RL78/G13 16-bit microcontroller with 16 KB flash, 2 KB RAM, and 4 KB data flash, operating from 1.6 V to 5.5 V at up to 32 MHz (41 DMIPS), featuring ultra-low-power HALT/STOP/SNOOZE modes (0.57 μA RTC+LVD), integrated 10-bit ADC (26 channels), and real-time clock - deployed in battery-powered sensor nodes and industrial control panels.
For engineers reviewing the R5F100BAANA#40 datasheet, R5F100BAANA#40 pinout, R5F100BAANA#40 application, or R5F100BAANA#40 equivalent, key selection criteria include its HWQFN-32 package (5 × 5 mm, 0.5-mm pitch), A-grade temperature range (–40°C to +85°C), on-chip debug support, self-programming flash with boot swap, and BGO-capable data flash rewrite during program execution.
Technical Context
The R5F100BAANA#40 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 subsystem clock). It integrates a 12-bit interval timer, calendar-based RTC with alarm and correction, and watchdog timer powered by dedicated low-speed oscillator.
Its peripheral set includes up to 16× 16-bit timers, 3× I²C/Simplified I²C channels, 2× UART/LIN interfaces, 2× CSI (SPI-compatible) channels, DMA controller (2 channels), 16×16-bit multiplier/divider/MAC, and on-chip voltage detector with 14-level LVD interrupt/reset selection - all optimized for deterministic real-time operation in resource-constrained embedded systems.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F100BCANA#40 | Same package and pinout; 32 KB flash, 2 KB RAM, 4 KB data flash | Higher code density for complex protocol stacks (e.g., BLE host, Modbus TCP) | Select when firmware exceeds 16 KB or requires larger data logging buffer |
| R5F101BAANA#40 | Same footprint and peripherals; no data flash (0 KB), reduced memory (16 KB flash, 2 KB RAM) | Cost-sensitive designs where field firmware updates or parameter storage are unnecessary | Choose for fixed-function controllers with static firmware and no runtime configuration needs |

FAQ
What is the operating temperature range for the R5F100BAANA#40?
The R5F100BAANA#40 is rated for A-grade industrial operation from –40°C to +85°C. This specification is confirmed in the RL78/G13 datasheet (R01DS0131EJ0380, Section 1.1), and applies specifically to part numbers ending in "A" such as R5F100BAANA#40. It does not support the extended G-grade (–40°C to +105°C) range.
Does the R5F100BAANA#40 include data flash memory?
Yes, the R5F100BAANA#40 includes 4 KB of on-chip data flash memory, supporting background operation (BGO), 1,000,000 write cycles (typical), and reprogramming at VDD = 1.8–5.5 V. This is explicitly listed in the RL78/G13 memory matrix (Page 2) and confirmed in Section 1.1 "Data Flash Memory" of the datasheet.
What package type and dimensions does the R5F100BAANA#40 use?
The R5F100BAANA#40 uses a 32-pin HWQFN package (5 × 5 mm body, 0.5-mm pitch), with exposed thermal pad and JEDEC-standard moisture sensitivity level 3. This is defined in Figure 1-1 and Table 1-1 (Page 5) of the RL78/G13 datasheet under "32-pin plastic HWQFN" and ordering code suffix "NA".
Can the R5F100BAANA#40 operate from a single 1.8 V supply?
Yes, the R5F100BAANA#40 supports single-supply operation from 1.6 V to 5.5 V. At 1.8 V, it achieves up to 8 MHz operation (per Section 1.1 "VDD = single power supply voltage of 1.6 to 5.5 V"), enabling compatibility with low-voltage battery systems while maintaining full peripheral functionality including ADC and RTC.
Is on-chip debug supported for the R5F100BAANA#40?
Yes, the R5F100BAANA#40 includes full on-chip debug functionality via the single-wire debug interface (SWD), compatible with Renesas E2 emulator and CS+ IDE. Debug features include breakpoint setting, memory/register access, and real-time trace - documented in Section 1.1 "On-chip debug function" and the RL78/G13 hardware manual.
