Product details
Overview
R5F100LGGFB#V0 from Renesas is a 64-pin LFQFP-0.5mm-pitch 16-bit RL78/G13 microcontroller with 512 KB flash, 8 KB data flash, 32 KB RAM, and industrial-grade operation up to +105°C. It delivers 41 DMIPS at 32 MHz, features ultra-low power consumption (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 for embedded control in HVAC, motor drives, and industrial sensors.
For engineers reviewing the R5F100LGGFB#V0 datasheet, R5F100LGGFB#V0 pinout, R5F100LGGFB#V0 application, or R5F100LGGFB#V0 equivalent, key selection criteria include its 64-pin LFQFP package, G-grade temperature range (−40°C to +105°C), integrated data flash with 1M-cycle endurance, SNOOZE mode for low-power sensor polling, and dual-voltage I/O supporting 1.8/2.5/3.3 V interfaces without level shifters.
Technical Context
The R5F100LGGFB#V0 implements the RL78 CPU core with CISC architecture and 3-stage pipeline, enabling instruction execution times from 0.03125 μs (32 MHz high-speed mode) to 30.5 μs (32.768 kHz subsystem clock). Its memory subsystem includes on-chip code flash with block erase security, background operation-capable data flash, and RAM partitioning optimized for flash library use (start address F7F00H).
Peripheral integration centers on deterministic real-time control: 16-channel 16-bit timers support PWM and input capture; the 10-bit ADC offers 26 analog inputs with internal 1.45 V reference and temperature sensor; serial interfaces include up to 10-channel simplified I²C, 4-channel UART with LIN support, and 8-channel CSI; DMA supports 4 channels with 2-clock transfers between SFR and RAM.

FAQ
What is the maximum operating frequency and corresponding performance of the R5F100LGGFB#V0?
The R5F100LGGFB#V0 operates at up to 32 MHz using its high-speed on-chip oscillator, delivering 41 DMIPS of processing performance. Its minimum instruction execution time is 0.03125 μs under this condition. The device also supports ultra-low-speed operation down to 32.768 kHz for RTC and low-power modes, with an instruction time of 30.5 μs. This dual-speed capability enables both high-performance control and energy-efficient standby states in the same R5F100LGGFB#V0 implementation.
Does the R5F100LGGFB#V0 include on-chip debug functionality?
Yes, the R5F100LGGFB#V0 includes full on-chip debug functionality supporting break, step, and watchpoint operations via the single-wire debug interface. It enables real-time debugging without halting peripheral operation in many cases, and supports flash programming and verification during development. This debug capability is integrated into the silicon and requires no external debug probe beyond standard Renesas E2 or E2 Lite emulators-streamlining firmware bring-up and validation for the R5F100LGGFB#V0.
How does the data flash endurance and rewrite voltage range impact system design for the R5F100LGGFB#V0?
The R5F100LGGFB#V0 data flash supports 1,000,000 write/erase cycles (typical) and operates across the full VDD range of 1.8–5.5 V. This eliminates voltage translation circuitry during field updates and guarantees long-term reliability for frequently modified parameters such as calibration coefficients or usage logs. Because the R5F100LGGFB#V0 supports background operation (BGO), these rewrites occur without stalling code execution-critical for real-time systems where deterministic response must be preserved during R5F100LGGFB#V0 firmware maintenance.
What packaging and compliance specifications apply to the R5F100LGGFB#V0?
The R5F100LGGFB#V0 is supplied in a 64-pin LFQFP package (10 × 10 mm, 0.5 mm pitch), lead-free and RoHS-compliant, with moisture sensitivity level (MSL) 3. It uses standard JEDEC-compliant tray packaging (#V0 suffix). The device meets industrial-grade reliability standards including AEC-Q100 stress testing for G-grade variants, and supports reflow soldering per J-STD-020. All mechanical and thermal data for the R5F100LGGFB#V0 are documented in Renesas package outline PLQP0064KF-A.
Can the R5F100LGGFB#V0 operate with mixed-voltage I/O interfaces?
Yes, the R5F100LGGFB#V0 supports different-potential interfaces: its N-ch open-drain I/O ports tolerate up to 6 V and can be configured for 1.8 V, 2.5 V, or 3.3 V logic levels without external level shifters. This capability simplifies interconnection with legacy sensors, low-voltage FPGAs, or multi-rail power architectures. The R5F100LGGFB#V0 achieves this through independent I/O voltage domain configuration and on-chip pull-up resistors-enabling direct, robust communication across voltage domains in a single R5F100LGGFB#V0-based design.
