Product details
Overview
R5F101CDALA#W0 from Renesas is a 32-bit RL78/G13 microcontroller with 48 KB flash memory, 2 KB RAM, and no data flash, housed in a 36-pin WFLGA (4 × 4 mm, 0.5-mm pitch) package. It operates from 1.6 V to 5.5 V, delivers 41 DMIPS at 32 MHz, and supports ultra-low-power modes including STOP (0.57 μA) and HALT, targeting battery-powered industrial sensors and smart meters.
For engineers reviewing the R5F101CDALA#W0 datasheet, R5F101CDALA#W0 pinout, R5F101CDALA#W0 application, or R5F101CDALA#W0 equivalent, key selection criteria include its 36-pin WFLGA footprint, absence of on-chip data flash, -40°C to +85°C industrial temperature grade (D), and integrated 10-bit ADC with up to 26 channels for analog-sensing edge nodes.
Technical Context
The R5F101CDALA#W0 implements the RL78 CPU core-a CISC architecture with 3-stage pipeline-supporting instruction execution times from 0.03125 μs (32 MHz high-speed mode) to 30.5 μs (32.768 kHz ultra-low-speed mode). Its memory map spans 1 MB address space with banked 8-bit general-purpose registers.
It integrates peripherals including eight 16-bit timers, one real-time clock with calendar/alarm functions, two UART/LIN channels, three I²C interfaces, two CSI/SPI channels, and an 8/10-bit A/D converter with internal 1.45 V reference and temperature sensor-configured exclusively in HS (high-speed main) mode.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F101CDASP#V0 | Same core, memory, and peripherals but in 30-pin LSSOP package with 0.65-mm pitch - larger footprint, through-hole compatible | Preferred for prototyping or manual assembly where WFLGA reflow is unavailable | Select when board-level rework or hand-soldering is required; not drop-in compatible due to package and pinout differences |
| R5F100CDALA#W0 | Identical package and pinout but includes 4 KB data flash - adds nonvolatile parameter storage capability | Suitable for field-upgradable devices requiring runtime configuration persistence | Choose when EEPROM-like parameter retention is needed; requires software adaptation for data flash access routines |
Compared with R5F101CDALA#W0, R5F101CDASP#V0 trades miniaturization for assembly flexibility, while R5F100CDALA#W0 adds data flash at the cost of slightly higher active current - both require PCB redesign and firmware review for integration.

FAQ
What is the operating temperature range for the R5F101CDALA#W0?
The R5F101CDALA#W0 is rated for industrial operation from -40°C to +85°C (denoted by the 'D' suffix in the part number). This makes it suitable for deployment in harsh environments such as factory floors, outdoor utility enclosures, and HVAC control units where ambient thermal stability cannot be guaranteed.
Does the R5F101CDALA#W0 include on-chip data flash memory?
No, the R5F101CDALA#W0 does not include data flash memory. As indicated by the '101' prefix in the Renesas part numbering scheme, this variant provides only code flash (48 KB) and SRAM (2 KB). For applications requiring nonvolatile parameter storage, consider the R5F100CDALA#W0, which includes 4 KB of data flash.
Which package type and dimensions does the R5F101CDALA#W0 use?
The R5F101CDALA#W0 uses a 36-pin WFLGA (Wafer-Level Glass Array) package measuring 4 mm × 4 mm with 0.5-mm pitch. It is a surface-mount, lead-free, moisture-sensitive device rated at MSL3 per JEDEC J-STD-020, requiring bake-out before reflow if exposed beyond floor life.
Can the R5F101CDALA#W0 operate from a single 1.8 V supply?
Yes, the R5F101CDALA#W0 supports operation from 1.6 V to 5.5 V, making it fully functional at 1.8 V. At this voltage, maximum clock frequency is reduced per datasheet specifications, but all peripherals-including the 10-bit ADC, RTC, and UART-remain operational, enabling compatibility with low-voltage battery systems.
How many analog input channels does the R5F101CDALA#W0 support?
The R5F101CDALA#W0 supports up to 26 analog input channels for its 8/10-bit A/D converter. Channel mapping depends on pin configuration and package; for the 36-pin WFLGA variant, up to 16 dedicated ANI pins are available, with additional channels accessible via alternate functions on shared I/O pins as defined in the pin configuration table.
