Product details
Overview
R5F100BCGNA#20 from Renesas is a 32-pin HWQFN-packaged 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 across -40°C to +105°C. It delivers 41 DMIPS at 32 MHz, features ultra-low-power modes (0.57 μA in RTC+LVD mode), integrated 10-bit ADC (26 channels), real-time clock, and multiple serial interfaces including UART, I²C, and CSI.
For engineers reviewing the R5F100BCGNA#20 datasheet, R5F100BCGNA#20 pinout, R5F100BCGNA#20 application, or R5F100BCGNA#20 equivalent, key selection criteria include industrial-temperature operation (−40°C to +105°C), compact 5 × 5 mm HWQFN package, on-chip debug support, self-programmable flash with boot swap, and BGO-capable data flash for concurrent execution and rewriting.
Technical Context
The R5F100BCGNA#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 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 channels of 16-bit timers, 2–4-channel DMA controller (2-cycle transfer between SFR and RAM), 16×16/32÷32 multiplier/divider/MAC unit, and flexible I/O with N-ch open-drain capability, TTL input buffers, and on-chip pull-up resistors-enabling direct interfacing with 1.8 V, 2.5 V, and 3 V logic systems.

Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F100BGNA#20 | Same 32-pin HWQFN package, identical 16 KB flash/2 KB RAM/4 KB data flash, but rated for −40°C to +85°C (D-grade) | Suitable for commercial/industrial ambient environments without extended temperature requirements | Select when full +105°C operation is unnecessary and cost optimization is prioritized |
| R5F101BCGNA#20 | Same pinout and package, but lacks data flash memory (0 KB); otherwise identical core/peripherals and temperature grade | Applicable where parameter storage is handled externally or not required | Choose when firmware does not require nonvolatile user data storage and BGO functionality is unused |
Compared with R5F100BCGNA#20, R5F100BGNA#20 trades extended temperature range for lower cost in standard industrial settings, while R5F101BCGNA#20 removes data flash to reduce silicon area-making it viable only when external EEPROM or flash suffices for configuration storage.

FAQ
What is the maximum operating frequency and corresponding DMIPS rating of the R5F100BCGNA#20?
The R5F100BCGNA#20 operates at up to 32 MHz and achieves 41 DMIPS performance as measured under EEMBC CoreMark benchmark conditions. This rating reflects its RL78 CPU core efficiency with 3-stage pipeline and optimized instruction set, enabling deterministic real-time response in motor control and sensor fusion applications where the R5F100BCGNA#20 is commonly deployed.
Does the R5F100BCGNA#20 support in-system programming and secure firmware updates?
Yes, the R5F100BCGNA#20 supports full in-system programming via its on-chip debug interface using TOOLRxD/TOOLTxD pins. It includes flash shield window and block erase prohibition features for security, plus boot swap functionality that enables atomic firmware updates with guaranteed rollback-critical for maintaining operational integrity during R5F100BCGNA#20 field deployments.
What analog capabilities does the R5F100BCGNA#20 provide for sensor interfacing?
The R5F100BCGNA#20 integrates a 10-bit successive-approximation ADC with up to 26 input channels, selectable internal 1.45 V reference or external AVREFP/AVREFM inputs, and built-in temperature sensor. These features allow direct connection of thermistors, potentiometers, current-sense amplifiers, and other analog sensors without external reference or signal conditioning-reducing system cost and complexity in R5F100BCGNA#20-based designs.
How does the R5F100BCGNA#20 manage power in battery-operated applications?
The R5F100BCGNA#20 offers three ultra-low-power modes: HALT (66 μA/MHz), STOP (0.57 μA with RTC and LVD active), and SNOOZE. Its STOP mode maintains calendar RTC and voltage monitoring while drawing sub-microamp current, enabling multi-year operation on coin cells. The R5F100BCGNA#20 also supports automatic wake-up via external interrupt or RTC alarm-eliminating need for external supervisors.
Is the R5F100BCGNA#20 pin-compatible with other RL78/G13 variants in the same package?
Yes, all RL78/G13 devices in the 32-pin HWQFN package-including R5F100BCGNA#20, R5F100BGNA#20, and R5F101BCGNA#20-share identical pinouts and mechanical footprint. This allows direct substitution within the same package family for memory, temperature grade, or data flash configuration changes without PCB redesign-provided firmware and peripheral initialization align with the selected variant's feature set.
