Product details
Overview
R5F101LCAFB#30 from Renesas is a 64-pin, LFQFP-0.5mm-pitch, 16 KB flash, 2 KB RAM, data-flash-free RL78/G13 16-bit microcontroller optimized for ultra-low-power industrial control applications. It delivers 41 DMIPS at 32 MHz, operates from 1.6–5.5 V, achieves 66 μA/MHz active current and 0.57 μA RTC+LVD standby, and integrates 16-channel 10-bit ADC, real-time clock, UART/SPI/I²C interfaces, and DMA.
For engineers reviewing the R5F101LCAFB#30 datasheet, R5F101LCAFB#30 pinout, R5F101LCAFB#30 application, or R5F101LCAFB#30 equivalent, key selection criteria include its 64-pin LFQFP package with industrial-grade -40°C to +85°C operation, absence of on-chip data flash (enabling cost-sensitive firmware-only deployments), and support for SNOOZE mode for sensor polling with minimal wake-up latency.
Technical Context
The R5F101LCAFB#30 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). Its memory map spans 1 MB address space, with 16 KB code flash organized in 1 KB blocks and 2 KB on-chip RAM.
Power management includes HALT, STOP, and SNOOZE modes; integrated peripherals include one 12-bit interval timer, one real-time clock with calendar/alarm, eight 16-bit timers, two UART channels (LIN-capable), up to ten I²C/Simplified I²C channels, and six analog inputs routed to its 10-bit ADC with internal 1.45 V reference.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F100LCAFB#30 | Includes 4 KB data flash; same 16 KB code flash, 2 KB RAM, and identical pinout/package | Required where firmware must store runtime parameters (e.g., calibration offsets, user settings) in nonvolatile memory | Select when field-updatable configuration storage is mandatory and cost premium for data flash is acceptable |
| R5F101LCDFB#30 | Same 64-pin LFQFP package and core specs, but rated for -40°C to +105°C industrial ambient | Needed in high-temperature environments such as motor drive enclosures or outdoor junction boxes | Choose for extended temperature operation; verify thermal derating of surrounding components matches +105°C rating |
Compared with R5F101LCAFB#30, R5F100LCAFB#30 adds data flash for parameter retention but increases cost and code size overhead, while R5F101LCDFB#30 trades standard industrial temperature range for extended thermal tolerance-neither offers pin-to-pin compatibility beyond shared package and footprint.

FAQ
What is the maximum operating frequency and corresponding DMIPS rating for the R5F101LCAFB#30?
The R5F101LCAFB#30 operates at up to 32 MHz and delivers 41 DMIPS of processing performance. This benchmark reflects its RL78 CPU core's 3-stage pipeline efficiency and is measured under standard conditions with cache enabled. The R5F101LCAFB#30 maintains this performance across its full 1.6–5.5 V supply range and industrial temperature grade.
Does the R5F101LCAFB#30 include on-chip data flash memory?
No, the R5F101LCAFB#30 does not include on-chip data flash memory. As indicated by the "101" prefix in its part number per Renesas' naming convention, it provides 16 KB of code flash only. Applications requiring nonvolatile parameter storage must use external EEPROM or leverage the code flash with wear-leveling firmware - unlike the R5F100LCAFB#30 variant which includes 4 KB of dedicated data flash.
What low-power modes are supported by the R5F101LCAFB#30, and what is the lowest achievable current draw?
The R5F101LCAFB#30 supports HALT, STOP, and SNOOZE modes. In STOP mode with only the real-time clock (RTC) and low-voltage detector (LVD) active, it draws just 0.57 μA at 25°C. This ultra-low quiescent current enables decade-long battery operation in maintenance-free sensor nodes and utility meters where periodic wake-up events are infrequent.
Which serial communication interfaces are integrated into the R5F101LCAFB#30?
The R5F101LCAFB#30 integrates two UART channels (with LIN-bus support), up to ten I²C/Simplified I²C channels, and two to eight CSI (Simplified SPI) channels. These interfaces share pins dynamically - for example, P10 serves as SCK00 (SPI clock) or SCL00 (I²C clock), and P11 functions as SI00 (SPI input), RxD0 (UART receive), or SDA00 (I²C data) - enabling flexible peripheral routing without additional level shifters.
What is the ADC resolution and analog input channel count for the R5F101LCAFB#30?
The R5F101LCAFB#30 features a 10-bit successive-approximation ADC with up to 26 analog input channels depending on package size; the 64-pin LFQFP variant supports at least 6 dedicated channels (ANI0–ANI5) plus extended channels like ANI18 on P147. It includes an internal 1.45 V reference voltage and supports both single-ended and differential measurement modes - eliminating external reference components in most sensor interface designs.
