Renesas R5F100GAGFB#V0

Overview

R5F100GAGFB#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, 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, and real-time clock - deployed in smart metering, industrial sensors, and battery-powered HMI control.

For engineers reviewing the R5F100GAGFB#V0 datasheet, R5F100GAGFB#V0 pinout, R5F100GAGFB#V0 application, or R5F100GAGFB#V0 equivalent, key selection criteria include its G-grade temperature range (–40°C to +105°C), integrated data flash with 1M rewrite cycles, SNOOZE mode for low-latency peripheral wake-up, and hardware multiplier/divider for deterministic motor control math.

Technical Context

The R5F100GAGFB#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). Its memory subsystem includes 128 KB code flash (1 KB block size), 8 KB background-operable data flash, and 12 KB SRAM - all accessible within a 1 MB address space.

Peripherals are tightly coupled to low-power operation: DMA controller (4 channels), 16-bit timer array (12 channels), 10-bit ADC with internal 1.45 V reference and temperature sensor, and dual UARTs with LIN bus support. Power management includes HALT/STOP/SNOOZE modes, on-chip POR and 14-level LVD, and selectable high-accuracy on-chip oscillator (±1.0% from 1–32 MHz).

FAQ

What is the maximum operating frequency and corresponding DMIPS rating for the R5F100GAGFB#V0?

The R5F100GAGFB#V0 operates at up to 32 MHz and delivers 41 DMIPS (Dhrystone MIPS) under standard test conditions. This performance level is achieved using the RL78 CPU core's 3-stage pipeline and high-speed on-chip oscillator, enabling efficient execution of real-time control algorithms and communication stacks without external clock sources.

Does the R5F100GAGFB#V0 include integrated data flash memory, and what is its endurance specification?

Yes, the R5F100GAGFB#V0 includes 8 KB of on-chip data flash memory rated for 1,000,000 write/erase cycles (typical) across the full VDD range of 1.8–5.5 V. This memory supports background operation (BGO), allowing concurrent program execution and data logging - a key capability for firmware updates and parameter retention in the R5F100GAGFB#V0.

What temperature grade does the R5F100GAGFB#V0 support, and how is this indicated in the part number?

The R5F100GAGFB#V0 is rated for industrial operation from –40°C to +105°C, denoted by the "G" in the third character position of the part number (R5F100GAGFB#V0). This grade ensures reliability in under-hood automotive, motor drives, and industrial control environments where ambient temperatures exceed +85°C.

How many analog input channels and what ADC resolution does the R5F100GAGFB#V0 provide?

The R5F100GAGFB#V0 integrates a 10-bit successive-approximation ADC with up to 26 configurable analog input channels. It also includes an internal 1.45 V reference voltage and on-die temperature sensor - enabling accurate, self-calibrated measurements for environmental monitoring and motor current sensing without external components in the R5F100GAGFB#V0.

What low-power modes are supported by the R5F100GAGFB#V0, and what is the lowest current consumption achievable?

The R5F100GAGFB#V0 supports HALT (66 μA/MHz), STOP (0.57 μA), and SNOOZE modes. In STOP mode with only RTC and LVD active, it achieves 0.57 μA typical current - ideal for battery-powered applications requiring long-term standby with periodic wake-up. SNOOZE mode further enables fast peripheral-triggered wake-up with minimal latency.
