Renesas R5F101GGAFB#V0

Overview

R5F101GGAFB#V0 from Renesas is a 48-pin LFQFP-packaged 16-bit RL78/G13 microcontroller with 96 KB flash, 8 KB RAM, and no data flash memory, operating from 1.6 V to 5.5 V across -40°C to +105°C industrial temperature range. It delivers 41 DMIPS at 32 MHz, features ultra-low-power operation (66 μA/MHz active, 0.57 μA RTC+LVD), and integrates 16-bit timers, 10-bit ADC (26 channels), UART, I²C, CSI, RTC, and watchdog - deployed in smart metering, industrial sensors, and battery-powered HMI.

For engineers reviewing the R5F101GGAFB#V0 datasheet, R5F101GGAFB#V0 pinout, R5F101GGAFB#V0 application, or R5F101GGAFB#V0 equivalent, key selection criteria include its industrial-grade temperature rating, absence of on-chip data flash, LFQFP-48 0.5-mm pitch package, real-time clock with calendar/alarm, and support for background data flash programming in compatible variants.

Technical Context

The R5F101GGAFB#V0 implements the RL78 CPU core with CISC architecture and 3-stage pipeline, supporting instruction execution times from 0.03125 μs (32 MHz high-speed mode) to 30.5 μs (32.768 kHz subsystem clock). Its memory map spans 1 MB address space, with general-purpose register banks enabling efficient context switching in interrupt-driven applications.

Power management includes HALT, STOP, and SNOOZE modes, POR, and LVD with 14 selectable voltage detection levels. Peripheral integration centers on dual DMA channels (2 clocks per 8/16-bit transfer), 16-bit timer array (12 channels), 12-bit interval timer, and hardware multiplier/divider for embedded control math.

FAQ

What is the maximum operating frequency and corresponding performance of the R5F101GGAFB#V0?

The R5F101GGAFB#V0 operates up to 32 MHz, delivering 41 DMIPS of processing performance. This is achieved using the high-speed on-chip oscillator with ±1.0% accuracy across 1.8–5.5 V and -20°C to +85°C, enabling deterministic real-time control in motor drives and sensor fusion applications. The R5F101GGAFB#V0 maintains this performance across its full industrial temperature range (-40°C to +105°C).

Does the R5F101GGAFB#V0 include on-chip data flash memory?

No, the R5F101GGAFB#V0 does not include on-chip data flash memory. Per Renesas part numbering convention, the "101" prefix indicates no data flash, distinguishing it from "100" series parts like R5F100GGAFB#V0 which integrate 8 KB data flash. The R5F101GGAFB#V0 relies on its 96 KB code flash for both program storage and limited parameter retention via flash wear-leveling techniques.

What package type and pin count does the R5F101GGAFB#V0 use?

The R5F101GGAFB#V0 uses a 48-pin LFQFP package with 7 mm × 7 mm body size and 0.5 mm pin pitch. The "FB" suffix in the part number explicitly denotes LFQFP, and "#V0" indicates tray packaging. This package provides robust thermal performance and hand-solderability while supporting all 48 signals including power, I/O, analog, and debug interfaces required by the RL78/G13 peripheral set.

What are the supported low-power modes and their typical current consumption for the R5F101GGAFB#V0?

The R5F101GGAFB#V0 supports HALT, STOP, and SNOOZE modes. In STOP mode with only RTC and LVD active, it consumes 0.57 μA - enabling decade-scale operation on coin cells. HALT mode draws 66 μA/MHz during active operation, and SNOOZE allows selective peripheral wake-up while CPU remains halted. All modes are fully supported across the -40°C to +105°C industrial temperature range of the R5F101GGAFB#V0.

Which serial communication interfaces are available on the R5F101GGAFB#V0?

The R5F101GGAFB#V0 integrates three serial interface types: CSI (SPI-compatible), UART (with LIN bus support), and I²C/Simplified I²C - configurable across multiple pin groups. It supports up to 2 CSI channels, 4 UART channels, and 10 I²C channels depending on pin assignment. These interfaces share pins flexibly, allowing designers to implement sensor networks, EEPROM communication, or fieldbus gateways without external logic, all within the R5F101GGAFB#V0's 48-pin constraint.
