Renesas R5F101GDDFB#V0

Overview

R5F101GDDFB#V0 from Renesas is a 48-pin LFQFP-packaged 16-bit RL78/G13 microcontroller with 64 KB flash, 4 KB data flash, 4 KB RAM, and industrial-grade operation up to +105°C. It delivers 41 DMIPS at 32 MHz, consumes only 66 μA/MHz active and 0.57 μA in RTC+LVD mode, and integrates 16-bit timers, 10-bit ADC (26 channels), UART/I²C/CSI interfaces, and hardware multiplier/divider for embedded control in power-constrained industrial systems.

For engineers reviewing the R5F101GDDFB#V0 datasheet, R5F101GDDFB#V0 pinout, R5F101GDDFB#V0 application, or R5F101GDDFB#V0 equivalent, key selection criteria include its 48-pin LFQFP-0.5mm package, absence of on-chip data flash (R5F101x series), -40°C to +105°C industrial temperature rating, and support for low-power STOP/HALT/SNOOZE modes in battery-backed sensor nodes and motor control modules.

Technical Context

The R5F101GDDFB#V0 implements the RL78 CPU core with CISC architecture, 3-stage pipeline, and configurable instruction timing (0.03125 μs @ 32 MHz to 30.5 μs @ 32.768 kHz). It supports dual-clock domains: high-speed main system clock (up to 32 MHz) and independent subsystem clock (32.768 kHz) for RTC and LVD operation during ultra-low-power modes.

Its peripheral set includes eight 16-bit timers, one 12-bit interval timer, calendar-based real-time clock with alarm and correction, watchdog timer, 10-bit A/D converter with internal reference (1.45 V) and temperature sensor, and three serial interface types (CSI, UART/LIN, I²C) - all accessible via dedicated SFRs and DMA channels (2-channel controller).

FAQ

What is the maximum operating frequency and corresponding DMIPS rating for the R5F101GDDFB#V0?

The R5F101GDDFB#V0 operates at up to 32 MHz and achieves 41 DMIPS performance per the RL78/G13 datasheet Rev.3.80. This metric reflects integer execution throughput under standard benchmark conditions and is validated across the full industrial temperature range (-40°C to +105°C) specified for the R5F101GDDFB#V0.

Does the R5F101GDDFB#V0 include on-chip data flash memory?

No, the R5F101GDDFB#V0 does not include on-chip data flash memory. As indicated by the "101" prefix in the part number per Renesas' RL78/G13 ordering guide, this variant omits data flash. Designers must use external nonvolatile memory (e.g., I²C EEPROM or SPI FRAM) for storing calibration data, device configuration, or firmware parameters.

What package type and pin count does the R5F101GDDFB#V0 use?

The R5F101GDDFB#V0 uses a 48-pin LFQFP package with 0.5 mm pitch, measuring 7 mm × 7 mm. The "FB" suffix in the part number explicitly denotes LFQFP, and the "#V0" packaging code indicates tray delivery - confirmed in Table 1-1 of the RL78/G13 datasheet R01DS0131EJ0380.

What is the operating temperature range certified for the R5F101GDDFB#V0?

The R5F101GDDFB#V0 is rated for industrial operation from -40°C to +105°C, as designated by the "G" grade suffix in the part number. This qualification is documented in Section 1.1 of the RL78/G13 datasheet and applies to all electrical specifications including flash programming, ADC accuracy, and oscillator stability.

Which low-power modes are supported by the R5F101GDDFB#V0, and what is the lowest achievable current consumption?

The R5F101GDDFB#V0 supports HALT, STOP, and SNOOZE modes. In STOP mode with only RTC and LVD active, it achieves 0.57 μA typical current consumption at VDD = 3.0 V and TA = 25°C - a value verified in the "Electrical Characteristics" section of the RL78/G13 datasheet and critical for battery-powered applications requiring multi-year runtime.
