Product details
Overview
R5F100LCGFA#V0 from Renesas is a 64-pin LQFP-0.65mm, industrial-grade RL78/G13 16-bit microcontroller with 128 KB flash memory, 8 KB data flash, 12 KB RAM, and integrated RTC, ADC, UART, I²C, and SPI interfaces. It operates from 1.6 V to 5.5 V, delivers 41 DMIPS at 32 MHz, and supports ultra-low-power modes (0.57 μA in STOP with RTC+LVD) for battery-powered sensor nodes and smart meters.
For engineers reviewing the R5F100LCGFA#V0 datasheet, R5F100LCGFA#V0 pinout, R5F100LCGFA#V0 application, or R5F100LCGFA#V0 equivalent, key selection criteria include its industrial temperature range (−40°C to +105°C), on-chip debug support, self-programmable flash with boot swap, background data flash rewriting, and hardware multiplier/divider for real-time control math.
Technical Context
The R5F100LCGFA#V0 implements the RL78 CPU core with 3-stage pipeline CISC architecture, supporting instruction execution times from 0.03125 μs (32 MHz high-speed mode) to 30.5 μs (32.768 kHz subsystem clock). It integrates dual-clock domains: high-speed on-chip oscillator (±1.0% accuracy, selectable 1–32 MHz) and dedicated low-speed oscillator for watchdog and RTC.
Its peripheral set includes up to 16× 16-bit timers, 1× 12-bit interval timer, 1× calendar RTC with alarm/correction, 10-bit 26-channel ADC with internal 1.45 V reference and temperature sensor, and 3× I²C/Simplified I²C channels - all configurable via register-based control without external glue logic.

Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F100LDGFA#V0 | Same package and pinout; 128 KB flash, 8 KB data flash, 12 KB RAM - identical memory configuration but different temperature grade (−40°C to +85°C, industrial D-grade). | Not rated for +105°C ambient; unsuitable for under-hood or high-temperature enclosure use. | Select when full industrial temperature range is not required and cost optimization is prioritized. |
| R5F101LCFA#V0 | Same 64-pin LQFP package; no data flash (0 KB), 128 KB code flash, 12 KB RAM, −40°C to +85°C operation. | Lacks data flash for nonvolatile parameter storage; requires external EEPROM or FRAM for field-updatable settings. | Choose where firmware updates are infrequent and calibration data is factory-programmed only. |
Compared with R5F100LDGFA#V0 and R5F101LCFA#V0, the R5F100LCGFA#V0 uniquely combines +105°C operation, 8 KB data flash with BGO, and full peripheral set - making it the only option among the three for high-reliability, field-configurable industrial endpoints requiring extended thermal margin.

FAQ
What is the maximum operating frequency and corresponding DMIPS rating for the R5F100LCGFA#V0?
The R5F100LCGFA#V0 achieves a maximum operating frequency of 32 MHz using its high-speed on-chip oscillator, delivering 41 DMIPS of processing performance. This benchmark reflects its RL78 CPU core's 3-stage pipeline efficiency and is measured under standard conditions per Renesas documentation. The R5F100LCGFA#V0 maintains this performance across its full 1.6–5.5 V supply range and −40°C to +105°C operating temperature.
Does the R5F100LCGFA#V0 include on-chip debug capability and what interface does it use?
Yes, the R5F100LCGFA#V0 includes full on-chip debug functionality compliant with Renesas' E1/E20 emulator standard. It uses a dedicated 6-pin debug interface (including RESET, CLK, RXD, TXD, TDI, TDO) supporting breakpoints, watchpoints, and real-time variable inspection without halting peripherals. This debug capability is integrated into the R5F100LCGFA#V0 silicon and requires no external debug ROM or bootloader - enabling seamless firmware development and field diagnostics.
What are the data flash endurance and rewrite voltage specifications for the R5F100LCGFA#V0?
The R5F100LCGFA#V0 features 8 KB of on-chip data flash rated for 1,000,000 write/erase cycles (typical) with rewrite voltage supported across the full VDD range of 1.8 V to 5.5 V. This allows safe in-field parameter updates even during brown-out conditions or mixed-voltage system operation. Background operation (BGO) enables concurrent code execution and data flash rewriting - a capability confirmed in the R01DS0131EJ0380 datasheet for the R5F100LCGFA#V0 variant.
Can the R5F100LCGFA#V0 operate from a single 1.8 V supply and still run its ADC and RTC?
Yes, the R5F100LCGFA#V0 supports full functionality-including 10-bit ADC conversion and calendar RTC operation-at VDD = 1.8 V. Its 1.6–5.5 V operating range is guaranteed across the entire −40°C to +105°C temperature span. At 1.8 V, the ADC maintains 10-bit resolution using the internal 1.45 V reference, and the RTC retains timekeeping accuracy via the dedicated low-speed oscillator - both verified in the RL78/G13 electrical characteristics tables for the R5F100LCGFA#V0.
What packaging and lead finish does the R5F100LCGFA#V0 use, and is it RoHS-compliant?
The R5F100LCGFA#V0 is supplied in a 64-pin LQFP package (12 mm × 12 mm, 0.65 mm pitch) with matte tin lead finish and complies fully with RoHS Directive 2011/65/EU and REACH SVHC regulations. The #V0 suffix denotes tray packaging per JEDEC J-STD-020 moisture sensitivity level 3, and the device meets IPC/JEDEC J-STD-020D reflow profile requirements - confirmed in Renesas' PLQP0064JA-A package outline and material declaration for the R5F100LCGFA#V0.
