Product details
Overview
R5F101CCALA#U0 from Renesas is a 36-pin, 16 KB flash, 4 KB data flash, 2 KB RAM 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 (26-channel), real-time clock, and UART/I²C/CSI interfaces - deployed in battery-powered industrial sensors and smart metering endpoints.
For engineers reviewing the R5F101CCALA#U0 datasheet, R5F101CCALA#U0 pinout, R5F101CCALA#U0 application, or R5F101CCALA#U0 equivalent, key selection criteria include its WFLGA-36 package, absence of on-chip data flash (R5F101x series), -40°C to +85°C industrial temperature grade (A suffix), and support for background data flash rewriting via BGO.
Technical Context
The R5F101CCALA#U0 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). 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.
Peripherals include up to 26-channel 10-bit A/D converter with internal 1.45 V reference and temperature sensor, 3–10-channel I²C/Simplified I²C, 2–4-channel UART/LIN, and 2–8-channel CSI (SPI-compatible serial interface), all operating across the full 1.6–5.5 V voltage range without external level shifters.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Core Architecture | RL78 16-bit CISC with 3-stage pipeline; enables deterministic timing control in safety-critical sensor firmware. |
| Flash Memory | 16 KB code flash (1 KB block size); supports self-programming with boot swap and flash shield window protection. |
| Data Flash | None (R5F101x series); eliminates need for external EEPROM in simple logging applications where non-volatile parameter storage is minimal. |
| RAM | 2 KB on-chip RAM; sufficient for RTOS task stacks and small buffer queues in sub-100 kB firmware images. |
| A/D Converter | 10-bit resolution, 26 input channels, internal 1.45 V reference; enables direct analog sensing of thermistors, potentiometers, and current shunts. |
| Power Modes | HALT (66 μA/MHz), STOP (0.57 μA), SNOOZE; extends coin-cell life beyond 5 years in periodic wake-up sensor nodes. |
| Operating Voltage | 1.6 V to 5.5 V single supply; allows direct Li-ion, 2×AA, or USB-powered operation without LDO overhead. |
Pinout & Package
Package: 36-pin WFLGA (4 × 4 mm, 0.5 mm pitch), moisture sensitivity level MSL3, lead-free and RoHS compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| P10/SCK00/SCL00 | SPI Clock / I²C Clock | Dual-function pin supports master/slave SPI or I²C communication; shared clock line reduces PCB routing complexity. |
| P11/SI00/RxD0/TOOLRxD/SDA00 | SPI Input / UART RX / I²C Data | Multi-protocol pin enables flexible peripheral connectivity - e.g., SPI to sensor, UART to modem, I²C to EEPROM - with software-selectable function. |
| P20/ANI0/AVREFP | Analog Input 0 / ADC Reference Positive | Configurable as first ADC channel or positive reference source; supports ratiometric measurements using external voltage dividers. |
| P21/ANI1/AVREFM | Analog Input 1 / ADC Reference Negative | Enables differential ADC mode when paired with P20; improves noise immunity in noisy industrial environments. |
| P30/INTP0/CLK0 | External Interrupt 0 / Subsystem Clock Input | Accepts 32.768 kHz crystal for RTC accuracy or external event trigger; eliminates need for separate interrupt controller IC. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low-power HALT mode | 66 μA/MHz at 32 MHz enables energy harvesting compatibility and >10-year battery life in wireless sensor nodes. |
| Background Operation (BGO) | Allows concurrent program execution and data flash rewrite - critical for field-upgradable firmware without runtime interruption. |
| On-chip voltage detector (LVD) | 14-level selectable reset/interrupt threshold ensures reliable brown-out detection across varying battery discharge curves. |
| Real-time clock with calendar | 99-year calendar, alarm, and clock correction supports time-stamped logging and scheduled wake-up without external RTC chip. |
| DMA controller (2 channels) | Reduces CPU load during high-speed peripheral transfers (e.g., ADC → RAM, UART TX buffer → shift register), freeing cycles for signal processing. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F100CCALA#U0 | Same 36-pin WFLGA package and peripherals, but includes 4 KB data flash and 2 KB RAM (vs. R5F101CCALA#U0's no-data-flash, 2 KB RAM). | Required where firmware must store calibration tables or field-upgradeable parameters without external memory. | Select R5F100CCALA#U0 if data flash persistence is mandatory; otherwise R5F101CCALA#U0 reduces BOM cost and simplifies flash management. |
| RL78/G14 R5F104BCANA#U0 | Successor family with 32 KB flash, 4 KB RAM, enhanced ADC (12-bit, 32 ch), and additional DMA channels; same 36-pin HWQFN package footprint. | Targeted at next-gen designs needing higher code density, richer analog front-end, or future-proofing against firmware growth. | Choose R5F104BCANA#U0 only when design requires ≥32 KB flash or 12-bit ADC precision; R5F101CCALA#U0 remains optimal for cost-sensitive, stable-feature-set deployments. |
Compared with R5F100CCALA#U0, the R5F101CCALA#U0 saves cost and layout area by omitting data flash while retaining identical peripheral set and power profile; versus RL78/G14 R5F104BCANA#U0, it offers proven reliability and lower toolchain migration effort for mature product lines.

FAQ
What is the maximum operating frequency and corresponding power consumption of the R5F101CCALA#U0?
The R5F101CCALA#U0 operates up to 32 MHz using its high-speed on-chip oscillator with ±1.0% accuracy. At this frequency, active-mode current is 66 μA per MHz - resulting in approximately 2.1 mA total at 32 MHz and 3.0 V supply. In STOP mode with RTC and LVD enabled, it draws just 0.57 μA, making R5F101CCALA#U0 ideal for multi-year battery applications.
Does the R5F101CCALA#U0 include on-chip data flash memory?
No, the R5F101CCALA#U0 does not include on-chip data flash memory. The "101" in the part number explicitly denotes the absence of data flash (per Renesas' RL78/G13 naming convention), distinguishing it from "100"-series variants like R5F100CCALA#U0 which integrate 4 KB data flash. R5F101CCALA#U0 relies on code flash for parameter storage or external non-volatile memory.
What package type and pin count does the R5F101CCALA#U0 use?
The R5F101CCALA#U0 uses a 36-pin WFLGA (Wafer-Level Glass Array) package measuring 4 mm × 4 mm with 0.5 mm pitch. This compact, near-chip-scale footprint supports high-density PCB layouts in space-constrained applications such as portable medical devices and smart sensors - and is confirmed by Renesas' official ordering information table for R5F101CCALA#U0.
Which communication interfaces are supported by the R5F101CCALA#U0?
The R5F101CCALA#U0 supports three primary serial interfaces: CSI (SPI-compatible, up to 8 channels), UART/LIN (up to 4 channels), and I²C/Simplified I²C (up to 10 channels). All operate across the full 1.6–5.5 V supply range. Pin multiplexing allows sharing of SCK00/SCL00 and SI00/RxD0/SDA00 lines across protocols - enabling flexible peripheral expansion without additional GPIOs in R5F101CCALA#U0 designs.
What is the operating temperature range specified for the R5F101CCALA#U0?
The R5F101CCALA#U0 is rated for an operating ambient temperature range of –40°C to +85°C, indicated by the "A" suffix in its part number per Renesas' RL78/G13 documentation. This qualifies it for industrial-grade deployment in environments such as factory automation controllers, HVAC systems, and outdoor utility equipment - distinct from "G"-suffix variants rated to +105°C.
