Product details
Overview
R5F100GLDFB#V0 from Renesas is a 48-pin LFQFP-packaged 16-bit RL78/G13 microcontroller with 128 KB flash, 8 KB data flash, 12 KB RAM, and industrial-grade operation up to +105°C. It delivers 41 DMIPS at 32 MHz, consumes just 66 μA/MHz active and 0.57 μA in RTC+LVD-only mode, and integrates UART, I²C, CSI, 16-bit timers, 10-bit ADC (26 channels), and real-time clock - deployed in smart meters, HVAC controllers, and industrial sensor nodes.
For engineers reviewing the R5F100GLDFB#V0 datasheet, R5F100GLDFB#V0 pinout, R5F100GLDFB#V0 application, or R5F100GLDFB#V0 equivalent, key selection criteria include its 48-pin LFQFP-0.5mm package, G-grade temperature range (−40°C to +105°C), integrated data flash with 1M rewrite cycles, low-power STOP/HALT/SNOOZE modes, and hardware multiplier/divider for deterministic control loops.
Technical Context
The R5F100GLDFB#V0 implements the RL78 CPU core - a CISC architecture with 3-stage pipeline and configurable instruction timing (0.03125 μs min @ 32 MHz, 30.5 μs @ 32.768 kHz). It supports background operation during data flash rewriting (BGO) and includes a dedicated low-speed on-chip oscillator for watchdog timer independence.
Its peripheral set includes up to 26-channel 10-bit ADC with internal 1.45 V reference and temperature sensor, 8–16 channels of 16-bit timer, 3–10 I²C/Simplified I²C channels, and 2–4 DMA channels enabling zero-cycle memory-to-peripheral transfers. All peripherals are clock-gated and power-managed via dedicated control registers.

FAQ
What is the maximum operating frequency and associated performance of the R5F100GLDFB#V0?
The R5F100GLDFB#V0 operates at up to 32 MHz, delivering 41 DMIPS of processing performance. Its RL78 CPU core achieves this with a 3-stage pipeline and high-accuracy on-chip oscillator (±1.0% over 1.8–5.5 V and −20 to +85°C). At lower frequencies - such as 32.768 kHz for RTC - instruction time extends to 30.5 μs, enabling ultra-low-power timing functions without external crystals.
Does the R5F100GLDFB#V0 support in-system programming and secure firmware updates?
Yes, the R5F100GLDFB#V0 supports full in-system programming via its on-chip debug interface. It includes boot swap functionality and flash shield window protection to prevent unauthorized access to code memory during field updates. Self-programming is enabled for both code and data flash, with background operation allowing concurrent execution and data flash rewriting.
What are the key low-power features of the R5F100GLDFB#V0 relevant for battery-powered designs?
The R5F100GLDFB#V0 offers HALT mode (0.23 μA), STOP mode (0.42 μA), and SNOOZE mode - where selected peripherals remain active while CPU sleeps. Its lowest active state is 0.57 μA with only RTC and LVD running. Combined with voltage detection (LVD) interrupt/reset across 14 levels and 1.6 V minimum supply, it enables decade-long operation on coin cells in sensor nodes and utility meters.
How many analog input channels does the R5F100GLDFB#V0 support, and what ADC resolution and references are available?
The R5F100GLDFB#V0 integrates a 10-bit successive-approximation ADC supporting up to 26 analog input channels. It provides an internal 1.45 V reference voltage and supports external reference inputs via AVREFP/AVREFM pins. The temperature sensor is accessible as a dedicated ADC channel, calibrated to ±2°C accuracy across the −40°C to +105°C range.
Is the R5F100GLDFB#V0 pin-compatible with other RL78/G13 variants in the same package?
Yes, all RL78/G13 devices in the 48-pin LFQFP package - including R5F100GLDFB#V0, R5F100GLAFB#V0, and R5F101GLDFB#V0 - share identical pinouts and electrical characteristics. This enables direct substitution within the same footprint for temperature grade or data flash requirement changes, without PCB redesign.
