Memory: 384 KB Flash program memory, 24 KB RAM, 8 KB Data Flash for nonvolatile data

I/O: 34 configurable GPIO pins

Analog: 10-bit A/D converter, multiple input channels

Interfaces: CSI/SPI, I2C, LIN bus, UART/USART

Peripherals: DMA, low-voltage detector (LVD), power-on reset (POR), PWM, watchdog timer (WDT), timers

Oscillator: Internal clock, supports external crystal options

Voltage range: 1.6 V to 5.5 V for battery and 5 V systems

Operating temperature: -40°C to +85°C (TA)

Series: RL78/G13, Base product number R5F100

Package: 48-LFQFP (7 x 7 mm), tape-and-reel

Compliance: RoHS3 compliant

Key Advantages

Very low power RL78 architecture for long battery life

Broad supply voltage range simplifies power design across 1.8 V and 5 V systems

Large on-chip Flash (384 KB) enables complex applications without external memory

Rich connectivity set for industrial and automotive (LIN, UART, SPI, I2C)

Integrated safety and robustness features (LVD, WDT, POR) for stable operation

Mature RL78 ecosystem with proven tools, libraries, and long-term support

Compact 48-pin footprint with 34 I/O to fit space-constrained designs

Packaging

Type: LQFP (Low-Profile Quad Flat Package), supplier designation 48-LFQFP

Body size: 7 x 7 mm nominal, low profile

Pin count and pitch: 48 pins, typical 0.5 mm pitch (check datasheet for exact pitch)

Material: Molded epoxy over copper lead frame, matte tin lead finish

Delivery: Tape and Reel (TR) for automated SMT assembly

Mounting: Surface mount, reflow soldering; observe moisture sensitivity handling

Thermal characteristics: Designed for -40°C to +85°C operation; thermal performance depends on PCB copper and airflow (see datasheet for θJA and de-rating guidance)

Electrical properties: 1.6 V to 5.5 V supply, 32 MHz max core clock, ESD and latch-up ratings defined in datasheet; adhere to recommended decoupling and layout

Lifecycle

Status: Active production as of the latest information; no formal discontinuation notice reported

In-family alternatives (same RL78 architecture, similar features, different memory or pin counts):

- RL78/G13 devices in 48-pin LQFP with smaller or larger Flash (for example 256 KB or 512 KB options)

- RL78/G14 family for more performance and extended timers while keeping similar voltage and package options

Cross-family alternatives (functional, not pin-compatible; verify requirements):

- Renesas RA2E1 (Arm Cortex-M23, low power, 48-pin options)

- TI MSP430 FR-series (16-bit, ultra-low power, similar mixed-signal features)

- Microchip PIC24F/PIC24E (16-bit, comparable peripherals, various 44–64 pin packages)

- NXP S12Z (16-bit, automotive-focused, LIN support)
