R5F100LHGBG#W0 RL78/G13 Processor Design and Memory Specifications

At its heart, the R5F100LHGBG#W0 uses the RL78 CISC core with a 3-stage instruction pipeline. The core is capable of a minimum instruction execution time as quick as 0.03125μs at 32MHz, adjustable down to 30.5μs for low-speed clock operation. The architecture features 1MB address space and four banks of general-purpose registers, supporting efficient task switching in complex control systems.

With 192KB of code FLASH (block erase size 1KB), integrated debug support, boot swap, and shield window functions, the controller is well equipped for reliable and secure firmware management. Data FLASH ranges from 4KB to 8KB, supporting up to 1,000,000 rewrite cycles, enabling frequent data logging and configuration updates without external EEPROM. RAM sizes vary from 2KB to 32KB, allowing flexible data buffering.

R5F100LHGBG#W0 RL78/G13 Pinout Layout and Package Options

The RL78/G13 family is available in a wide array of packages—ranging from 20 to 128 pins—to accommodate diverse board layouts and peripheral demands. For R5F100LHGBG#W0, the 64-VFBGA package offers minimized footprint and high I/O density (64 pins, 0.4mm pitch). Engineers can select from LQFP, LFQFP, HWQFN, WFLGA, and LSSOP variants depending on space constraints, number of channels required, and targeted application. It is critical to observe recommended connections, such as the REGC pin requiring a 0.47μF–1μF capacitor to Vss, to ensure stable operation. Pins can be reassigned via the peripheral I/O redirection register (PIOR), giving flexibility in signal mapping.

R5F100LHGBG#W0 RL78/G13 Power Requirements and Operating States

The microcontroller is rated for operation from -40°C to +85°C (consumer/industrial grades) and up to +105°C for industrial models. Absolute maximum ratings must be observed to maintain device integrity; these include pin voltage limits and total output currents which are duty-cycle dependent (e.g., total pin current at 80% duty scales accordingly).

Three principal CPU operation modes optimize tradeoffs between speed and energy: high-speed main (HS), low-speed main (LS), and low-voltage main (LV). Each mode has specific supply voltage and clock frequency ranges (e.g., HS: 2.7V–5.5V @ 1–32MHz), important for power budget calculations and timing analysis. Stop, HALT, and SNOOZE modes offer further system-level current reductions during idle periods or RTC-only operation.

R5F100LHGBG#W0 RL78/G13 External Connections and Communication Support

Connectivity is a highlight, with configurable interfaces including:

UART (LIN support): up to 4 channels, compatible with voltages as low as 1.8V for interfacing with external modules.

Simplified SPI (CSI): 2–8 channels, master/slave functionality with full I/O redirection.

I²C: 3–10 channels, supporting standard to fast-plus modes and communication at varied potentials (1.8V, 2.5V, 3V).

DMA controller: 2/4 channels for rapid memory-to-peripheral transfer.

Communication timing and buffer configurations are adaptable via internal registers, and dedicated logic allows interfaces to operate safely at different voltage domains—an essential feature for high-mix system boards.

R5F100LHGBG#W0 RL78/G13 Analog-to-Digital Features and Analog Functions

The R5F100LHGBG#W0 integrates up to 26 analog input channels, supporting both 8- and 10-bit ADC resolutions. Reference voltages can be supplied externally or derived internally, with temperature sensor support. Conversion errors (linearity, zero/full scale) are tightly controlled and well documented, depending on reference and supply voltage. Internal voltage monitoring and on-chip reference enable designs that require reliable sensor readouts and voltage supervision (LVD circuit included).

R5F100LHGBG#W0 RL78/G13 Energy Control and Data Preservation

Comprehensive power-on-reset (POR) and low-voltage detection (LVD) circuits provide secure startup and voltage fault protection. RAM data retention is preserved until POR thresholds are crossed, valuable in power drop scenarios. The device supports deployment in noisy environments by allowing separation of analog and digital power/ground planes through specific pin connections.

R5F100LHGBG#W0 RL78/G13 Comparable or Alternative Device Models

For engineers and purchasing teams evaluating alternates or future-proofing supply, other members of the RL78/G13 series can serve as direct replacements, sharing core pinout, memory type, and CPU functionality, with variations only in FLASH size, RAM, and package. For applications requiring higher or lower memory, or a different I/O count, consider RL78/G13 models with 16KB–512KB FLASH and pin variants ranging from 20 to 128. Additionally, devices like R5F100xxAxx (consumer grade) and R5F100xxGxx (industrial grade up to +105°C) provide similar functionality. Careful cross-referencing of individual electrical and packaging characteristics will ensure seamless interchangeability.
