Product details
Overview
R5F101GDDFB#30 from Renesas is a 48-pin LFQFP-packaged 16-bit RL78/G13 microcontroller with 64 KB flash, 4 KB data flash, and 4 KB RAM, operating from 1.6 V to 5.5 V at up to 32 MHz (41 DMIPS), featuring ultra-low-power modes (0.57 μA RTC+LVD), 10-bit ADC (26 channels), and integrated real-time clock - deployed in industrial sensor nodes and battery-powered control modules.
For engineers reviewing the R5F101GDDFB#30 datasheet, R5F101GDDFB#30 pinout, R5F101GDDFB#30 application, or R5F101GDDFB#30 equivalent, key selection criteria include its industrial-grade temperature range (−40°C to +85°C), absence of on-chip data flash (confirmed by "101" suffix), LFQFP-48 package with 0.5-mm pitch, and support for LIN-bus UART, CSI, and I²C interfaces in resource-constrained embedded designs.
Technical Context
The R5F101GDDFB#30 implements the RL78 CPU core with CISC architecture and 3-stage pipeline, enabling instruction execution times from 0.03125 μs (32 MHz high-speed mode) to 30.5 μs (32.768 kHz subsystem clock). It integrates a 12-bit interval timer, calendar-based real-time clock with alarm and correction, and watchdog timer powered by dedicated low-speed oscillator.
Its peripheral set includes up to 26-channel 10-bit A/D converter with internal 1.45 V reference and temperature sensor, 8–16 channels of 16-bit timers, 2–4 DMA channels (2-clock transfer between SFR and RAM), and serial interfaces: 2–4 UART/LIN, 2–8 CSI, and 3–10 I²C channels - all configurable without external components for deterministic timing-critical firmware.

FAQ
Does R5F101GDDFB#30 include on-chip data flash memory?
No, R5F101GDDFB#30 does not include on-chip data flash memory. The "101" in the part number explicitly denotes zero data flash capacity, distinguishing it from "100"-series variants like R5F100GDDFB#30 which integrate 4 KB of data flash. This simplifies firmware design for fixed-parameter applications and reduces cost.
What is the maximum operating temperature range for R5F101GDDFB#30?
The R5F101GDDFB#30 is rated for industrial operation from −40°C to +85°C, as indicated by the "D" suffix in its ordering code. It is not qualified for the extended −40°C to +105°C range (denoted by "G" grade) and must be used within its specified ambient limits to guarantee electrical performance and reliability.
Which package type and footprint does R5F101GDDFB#30 use?
R5F101GDDFB#30 uses a 48-pin LFQFP package (PLQP0048KB-B) with 7 mm × 7 mm body size and 0.5-mm lead pitch. It is lead-free and RoHS-compliant, and shares mechanical compatibility with other RL78/G13 48-pin LFQFP variants - enabling layout reuse across family members.
Can R5F101GDDFB#30 operate from a 1.8 V supply?
Yes, R5F101GDDFB#30 supports operation from 1.6 V to 5.5 V, including 1.8 V nominal supply. At 1.8 V, it achieves up to 16 MHz maximum frequency (per datasheet voltage-frequency curve), maintaining full peripheral functionality including ADC, timers, and serial interfaces - ideal for dual-cell Li-ion or primary battery systems.
Does R5F101GDDFB#30 support LIN bus communication?
Yes, R5F101GDDFB#30 supports LIN bus communication through its UART peripherals, which include LIN physical layer compliance (LIN 2.2A/SAE J2602). UART0 and UART1 can be configured as LIN master or slave nodes with automatic sync-break detection, checksum generation, and identifier filtering - no external transceiver required for basic implementation.
Is there a pin-compatible upgrade path from R5F101GDDFB#30 to a higher-performance MCU?
R5F101GDDFB#30 has no pin-compatible higher-performance upgrade within the RL78 family. The RL78/G14 R5F11GDDFB#30 shares the same LFQFP-48 package but differs in memory map and peripheral register layout; migration requires firmware and PCB-level validation. For true pin-compatible scaling, consider Renesas' RL78/G23 with enhanced core and peripheral set - though not drop-in.
