Product details
Overview
R5F101GADFB#V0 from Renesas is a 48-pin LFQFP-packaged 16-bit RL78/G13 microcontroller with 128 KB flash, 8 KB RAM, and no data flash memory, operating from 1.6 V to 5.5 V across -40°C to +85°C industrial temperature range. It delivers 41 DMIPS at 32 MHz, integrates 10-bit ADC (26 channels), RTC, UART/SPI/I²C interfaces, and ultra-low-power STOP mode (0.57 μA) for battery-powered sensor nodes and industrial control units.
For engineers reviewing the R5F101GADFB#V0 datasheet, R5F101GADFB#V0 pinout, R5F101GADFB#V0 application, or R5F101GADFB#V0 equivalent, key selection criteria include its 48-pin LFQFP-0.5 mm pitch package, absence of on-chip data flash, industrial-grade temperature rating, and support for SNOOZE-mode peripheral wake-up without CPU intervention.
Technical Context
The R5F101GADFB#V0 implements the RL78 CPU core with 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 architecture separates 128 KB code flash (1 KB block size) from 8 KB SRAM, with no dedicated data flash - requiring external EEPROM or flash for nonvolatile parameter storage.
Peripheral integration includes eight 16-bit timers, one 12-bit interval timer, calendar-capable RTC with alarm and correction, and three I²C channels - all accessible via configurable GPIO pins mapped to P0–P15 ports. Power management features HALT, STOP, and SNOOZE modes, with LVD interrupt/reset selectable across 14 voltage thresholds.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Core Architecture | RL78 16-bit CISC with 3-stage pipeline; enables deterministic real-time response in resource-constrained embedded systems. |
| Max Operating Frequency | 32 MHz; achieves 41 DMIPS performance for mid-tier control tasks without external clock source dependency. |
| Flash Memory | 128 KB code flash (1 KB erase blocks); supports self-programming with boot swap and flash shield window security. |
| RAM Size | 8 KB on-chip SRAM; sufficient for RTOS stacks, communication buffers, and control algorithm variables. |
| ADC Resolution & Channels | 10-bit resolution with up to 26 analog inputs; includes internal 1.45 V reference and temperature sensor for calibration-free sensing. |
| Operating Voltage Range | 1.6 V to 5.5 V; allows direct interface with 1.8 V, 3.3 V, and 5 V logic domains and single-supply battery operation. |
| Low-Power Modes | STOP mode draws 0.57 μA (RTC + LVD active); enables multi-year battery life in metering and IoT endpoint applications. |
Pinout & Package
Package: 48-pin LFQFP (7 mm × 7 mm, 0.5 mm pitch), RoHS-compliant, moisture sensitivity level 3.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD, VSS | Power supply and ground | Dual power/ground pairs ensure stable core and I/O rail decoupling; supports mixed-voltage I/O with independent EVDD option. |
| P00–P07, P10–P17, P20–P27, P30–P37, P40–P47, P50–P57 | General-purpose I/O ports | 48 total GPIO pins; configurable as N-ch open-drain (6 V tolerant), TTL input, or pull-up; supports key interrupt and clock output functions. |

Key Features
| Feature | Design Value |
|---|---|
| Ultra-low-power STOP mode | 0.57 μA current draw with RTC and LVD active - enables decade-scale battery life in remote sensors. |
| On-chip high-accuracy oscillator | +/-1.0% frequency stability (1.8–5.5 V, -20 to +85°C); eliminates need for external crystal in cost-sensitive designs. |
| Background data flash rewrite | Not applicable - R5F101GADFB#V0 has no data flash; code flash self-programming requires CPU halt during erase/write. |
| SNOOZE mode peripheral operation | UART, CSI, and I²C can operate autonomously while CPU remains halted - reduces active time and average power. |
| Hardware multiplier/divider | 16×16→32-bit multiply, 32÷32→32-bit divide, and MAC operations accelerate motor control and filtering algorithms. |
| Real-time clock with calendar | 99-year calendar, alarm, and auto-correction; maintains accurate timekeeping across power cycles without external RTC chip. |

Code flash is 128 KB, and SRAM is 8 KB. For applications requiring nonvolatile parameter storage, external EEPROM or flash memory must be used, or consider R5F100GADFB#V0 which includes 4 KB data flash.
What is the maximum ADC channel count supported by R5F101GADFB#V0?
R5F101GADFB#V0 supports up to 26 analog input channels for its 10-bit ADC. This count is confirmed in the RL78/G13 datasheet Section 1.1 Features and applies to 48-pin variants including this part. Channel mapping is distributed across P0–P5 ports, with ANI0–ANI25 designated in the pin configuration table.
Is R5F101GADFB#V0 pin-compatible with R5F100GADFB#V0?
Yes, R5F101GADFB#V0 is pin-compatible with R5F100GADFB#V0. Both use identical 48-pin LFQFP-0.5 mm pitch packages (PLQP0048KF-A), share identical pin functions and electrical characteristics, and differ only in the presence of data flash memory - making them drop-in replacements where data flash is not required.
What industrial temperature range does R5F101GADFB#V0 support?
R5F101GADFB#V0 supports an operating ambient temperature range of -40°C to +85°C, classified under "D" grade for industrial applications per Renesas RL78/G13 ordering part number conventions. This rating is validated across all electrical specifications including flash endurance, ADC accuracy, and oscillator stability.
Can R5F101GADFB#V0 operate from a 1.8 V supply?
Yes, R5F101GADFB#V0 operates from 1.6 V to 5.5 V, fully supporting 1.8 V supply. At 1.8 V, it achieves up to 16 MHz operation (per datasheet DC characteristics), enabling ultra-low-power operation while maintaining compatibility with 1.8 V logic families and battery chemistries like LiFePO₄.
