Product details
Overview
R5F101GCANA#20 from Renesas is a 20-pin, 16 KB flash, data-flash-free RL78/G13 16-bit microcontroller with ultra-low-power operation (66 μA/MHz active, 0.57 μA RTC+LVD mode), 1.6–5.5 V supply, and integrated 10-bit ADC (6 channels), 16-bit timers (8 channels), UART/SPI/I²C interfaces, and real-time clock. It targets battery-powered sensor nodes and compact industrial control modules.
For engineers reviewing the R5F101GCANA#20 datasheet, R5F101GCANA#20 pinout, R5F101GCANA#20 application, or R5F101GCANA#20 equivalent, key selection criteria include its 20-pin HWQFN package, absence of data flash memory, -40°C to +85°C industrial temperature grade (D), and support for SNOOZE/STOP/HALT low-power modes in resource-constrained embedded designs.
Technical Context
The R5F101GCANA#20 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 map includes 16 KB code flash (1 KB block size), 2 KB RAM, and no data flash - confirmed by the "101" family designation indicating data flash omission.
Peripheral integration includes one 12-bit interval timer, one real-time clock with calendar/alarm, eight 16-bit timers, six-channel 10-bit ADC with internal 1.45 V reference, and serial interfaces: CSI (SPI-compatible), UART (LIN-capable), and I²C - all mapped to its 20-pin HWQFN footprint with dedicated analog input pins (P20–P22, P147) and programmable I/O pull-ups.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Core Architecture | RL78 16-bit CISC with 3-stage pipeline; enables deterministic timing and efficient code density for cost-sensitive control applications. |
| Flash Memory | 16 KB code flash (1 KB erase blocks); supports self-programming with boot swap and flash shield window for firmware security. |
| RAM | 2 KB on-chip RAM; sufficient for real-time control stacks, ISR context storage, and small data buffers without external memory. |
| Supply Voltage | 1.6 V to 5.5 V; allows direct interface with Li-ion, alkaline, or regulated 3.3 V/5 V rails without level-shifting. |
| Power Consumption | 66 μA/MHz active current; 0.57 μA in STOP mode with RTC + LVD active - extends battery life in always-on sensing nodes. |
| Analog Peripherals | 6-channel 10-bit ADC with internal 1.45 V reference and temperature sensor; enables local environmental monitoring without external references. |
| Timers & RTC | Eight 16-bit timers + one 12-bit interval timer + calendar RTC (99-year range, alarm, clock correction); supports precise scheduling and time-stamped event logging. |
Pinout & Package
Package: 20-pin HWQFN (4 × 4 mm, 0.5 mm pitch), moisture sensitivity level (MSL) 3, RoHS-compliant, thermal pad exposed on bottom for enhanced heat dissipation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| P10 | SCK00 / SCL00 | Serial clock output for CSI0 or I²C master/slave; shared function enables flexible peripheral routing in space-constrained layouts. |
| P11 | SI00 / RxD0 / TOOLRxD / SDA00 | Multi-function pin for SPI input, UART receive, debug RX, or I²C data - simplifies board bring-up and reduces external component count. |
| P20 | ANI0 / AVREFP | Analog input channel 0 and positive ADC reference voltage input; supports ratiometric measurements with external sensor bridges. |
| P21 | ANI1 / AVREFM | Analog input channel 1 and negative ADC reference input; enables differential ADC sampling and precision offset calibration. |
| P22 | ANI2 | Analog input channel 2; provides third dedicated sensor input without multiplexing delay or crosstalk. |
| P147 | ANI18 | Analog input channel 18; expands analog sensing capability beyond primary bank, useful for multi-zone monitoring. |
| VDD | Power Supply | Main digital/analog supply (1.6–5.5 V); single-rail operation eliminates need for separate analog/digital regulators. |
| VSS | Ground | Digital ground reference; shared with analog ground but requires star-point layout to maintain ADC accuracy. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low-power STOP mode | 0.57 μA with RTC + LVD active - enables decade-scale battery life in wireless sensor endpoints using coin cells. |
| On-chip high-accuracy oscillator | +/-1.0% over 1.8–5.5 V and -20 to +85°C - eliminates external crystal for UART/LIN timing-critical comms. |
| Hardware DMA controller | 2-channel DMA with 2-clock transfers between SFR and RAM - offloads CPU during ADC burst reads or UART streaming. |
| Integrated LIN bus support | UART peripheral with LIN break detection and sync field generation - reduces BOM cost in automotive body electronics. |
| On-chip voltage detector (LVD) | 14-level selectable reset/interrupt threshold - enables graceful shutdown or brown-out recovery without external supervisor IC. |

FAQ
What is the operating temperature range for the R5F101GCANA#20?
The R5F101GCANA#20 is rated for industrial operation from -40°C to +85°C (grade D), validated across full voltage (1.6–5.5 V) and frequency ranges. This makes it suitable for deployment in factory automation panels, outdoor sensor enclosures, and HVAC control units without thermal derating.
Does the R5F101GCANA#20 include data flash memory?
No, the R5F101GCANA#20 does not include data flash memory. The "101" in its part number explicitly denotes data flash omission per Renesas RL78/G13 naming convention. It retains 16 KB code flash and 2 KB RAM, with self-programming supported only for code memory.
Which package type and pin count does the R5F101GCANA#20 use?
The R5F101GCANA#20 uses a 20-pin HWQFN package (4 × 4 mm, 0.5 mm pitch) with an exposed thermal pad. This compact, leadless package supports high-density PCB layouts and offers superior thermal performance compared to TSSOP alternatives in the same pin count.
Can the R5F101GCANA#20 operate without an external crystal?
Yes, the R5F101GCANA#20 integrates a high-accuracy on-chip oscillator (±1.0% over -20 to +85°C, 1.8–5.5 V) configurable from 1 MHz to 32 MHz. This eliminates the need for external crystals in UART, LIN, or SPI applications where ±1% timing tolerance is acceptable.
How many analog input channels are accessible on the R5F101GCANA#20?
The R5F101GCANA#20 provides six analog input channels: ANI0 through ANI2 on P20–P22, plus ANI18 on P147, and two additional channels routed to other pins (not visible in 20-pin top view but documented in full RL78/G13 datasheet). All support 10-bit resolution with internal 1.45 V reference.
