Product details
Overview
R5F100LCABG#U0 from Renesas is a 16-bit RL78/G13 microcontroller with 512 KB flash, 8 KB data flash, and 32 KB RAM, 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 (66 μA/MHz active, 0.57 μA RTC+LVD), and integrates 16-bit timers, 10-bit ADC (26 channels), UART/LIN, I²C, CSI, RTC, and hardware multiplier/divider - deployed in industrial motor control and smart sensor nodes.
For engineers reviewing the R5F100LCABG#U0 datasheet, R5F100LCABG#U0 pinout, R5F100LCABG#U0 application, or R5F100LCABG#U0 equivalent, key selection criteria include its VFBGA-64 package with 0.4 mm pitch, industrial-grade temperature range (-40°C to +105°C), integrated data flash with 1M write cycles, background operation during program execution, and support for SNOOZE mode for low-latency wake-up in battery-powered edge devices.
Technical Context
The R5F100LCABG#U0 implements the RL78 CPU core with CISC architecture and 3-stage pipeline, enabling configurable instruction timing from 0.03125 μs (32 MHz high-speed oscillator) to 30.5 μs (32.768 kHz subsystem clock). Its memory subsystem includes 512 KB code flash with 1 KB block erase, 8 KB data flash supporting background operation (BGO), and 32 KB on-chip RAM.
Peripherals are tightly coupled to power efficiency: DMA controller (4 channels), 16-bit timer array (16 channels), real-time clock with calendar/alarm/correction, 10-bit ADC with internal reference (1.45 V) and temperature sensor, and dual-voltage I/O (1.8/2.5/3 V interface compatibility). All operate within the same 1.6–5.5 V supply range and full industrial temperature grade.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F100LGABG#U0 | Same VFBGA-64 package and G-grade temp range, but 128 KB flash / 8 KB data flash / 12 KB RAM | Targeted at cost-sensitive industrial controls where full 512 KB flash is unnecessary | Select when firmware size <128 KB and BOM cost optimization is prioritized over future scalability |
| R5F101LCABG#U0 | Identical pinout and package, but lacks data flash (0 KB); retains 512 KB code flash and 32 KB RAM | Suitable for applications requiring large program storage but no field-updatable parameter storage | Choose when EEPROM-like nonvolatile parameter storage is handled externally or not required |
Compared with R5F100LCABG#U0, R5F100LGABG#U0 trades flash/RAM capacity for lower unit cost in fixed-function systems, while R5F101LCABG#U0 removes data flash to simplify qualification and reduce test overhead - both retain identical industrial temperature rating and ultra-low-power architecture.

FAQ
What is the maximum operating frequency and corresponding performance of the R5F100LCABG#U0?
The R5F100LCABG#U0 operates up to 32 MHz using its high-accuracy on-chip oscillator (±1.0% over -20°C to +85°C), delivering 41 DMIPS. Its RL78 core achieves this with a 3-stage pipeline and supports configurable instruction timing - from 0.03125 μs at full speed to 30.5 μs in ultra-low-speed 32.768 kHz mode - making the R5F100LCABG#U0 adaptable to both high-throughput and extreme low-power use cases.
Does the R5F100LCABG#U0 support in-system programming and secure firmware updates?
Yes, the R5F100LCABG#U0 supports full in-system programming via its on-chip debug interface and includes self-programming capabilities with boot swap function and flash shield window protection. These features allow safe, field-upgradable firmware with rollback support and prevention of unauthorized flash access - critical for maintaining security and reliability in deployed R5F100LCABG#U0-based systems.
What are the key low-power modes available on the R5F100LCABG#U0, and what is the lowest achievable current draw?
The R5F100LCABG#U0 offers HALT, STOP, and SNOOZE modes. In STOP mode with only RTC and LVD active, it draws just 0.57 μA - verified across -40°C to +105°C. SNOOZE mode enables ultra-fast wake-up (<1 μs) from UART, CSI, or LIN activity while keeping CPU halted, making the R5F100LCABG#U0 especially effective in intermittently active sensor or communication nodes.
How does the data flash memory in the R5F100LCABG#U0 differ from standard code flash, and what is its endurance?
The R5F100LCABG#U0 includes 8 KB of dedicated data flash memory rated for 1,000,000 write cycles (typical), with background operation (BGO) allowing code execution from main flash while rewriting data flash. Unlike code flash, it supports byte-level writes and is optimized for frequent parameter storage - such as calibration data or event logs - without disrupting real-time operation of the R5F100LCABG#U0.
Is the R5F100LCABG#U0 pin-compatible with other RL78/G13 devices in the VFBGA-64 package?
Yes, all RL78/G13 devices in the VFBGA-64 package - including R5F100LCABG#U0, R5F100LGABG#U0, and R5F101LCABG#U0 - share identical pinouts and footprint. This enables hardware reuse across variants differing only in memory configuration or data flash presence, simplifying design scaling and migration paths for the R5F100LCABG#U0 within the same family.
