Product details
Overview
R5F101ADASP#V0 from Renesas is a 32-bit RL78/G13 microcontroller with 32 KB flash memory, 2 KB RAM, and no data flash, designed for ultra-low-power industrial applications operating from –40°C to +85°C. It delivers 41 DMIPS at 32 MHz, consumes just 66 μA/MHz active current and 0.57 μA in RTC+LVD-only mode, and integrates 10-bit ADC (6 channels), UART/SPI/I²C interfaces, and real-time clock - ideal for battery-powered sensor nodes and smart meters.
For engineers reviewing the R5F101ADASP#V0 datasheet, R5F101ADASP#V0 pinout, R5F101ADASP#V0 application, or R5F101ADASP#V0 equivalent, key selection criteria include its LSSOP-30 package, industrial temperature grade (D-suffix), absence of data flash, low-voltage operation (1.6–5.5 V), and support for SNOOZE/STOP/HALT power modes in resource-constrained embedded control designs.
Technical Context
The R5F101ADASP#V0 implements the RL78 CPU core with CISC architecture and 3-stage pipeline, enabling configurable instruction timing 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 on-chip RAM banks supporting DMA transfers requiring only 2 clocks per 8/16-bit SFR-to-RAM operation.
It features a high-accuracy ±1.0% on-chip oscillator (selectable 1–32 MHz), integrated LVD with 14-level interrupt/reset options, and hardware peripherals including 8× 16-bit timers, 1× real-time clock with calendar/alarm, and 1× watchdog timer driven by dedicated low-speed oscillator - all optimized for deterministic real-time control in cost-sensitive industrial systems.

FAQ
What is the maximum operating frequency and performance rating of the R5F101ADASP#V0?
The R5F101ADASP#V0 operates at up to 32 MHz and delivers 41 DMIPS (Dhrystone MIPS) performance. Its RL78 CPU core achieves this with a 3-stage pipeline and configurable instruction timing - 0.03125 μs minimum execution time at 32 MHz using the high-speed on-chip oscillator. This performance level supports real-time control loops and protocol stack processing in compact industrial firmware.
Does the R5F101ADASP#V0 include data flash memory?
No, the R5F101ADASP#V0 does not include data flash memory. As indicated by the "101" in its part number (per Renesas RL78/G13 naming convention), it provides 32 KB of code flash and 2 KB of RAM but zero data flash. This distinguishes it from "100"-series variants like R5F100ADASP#V0, which integrate 4 KB of data flash for runtime parameter storage and background rewriting.
What package type and pin count does the R5F101ADASP#V0 use?
The R5F101ADASP#V0 uses a 30-pin LSSOP (Low-Profile Small Outline Package) with 7.62 mm × 9.9 mm dimensions and 0.65 mm lead pitch. The "ASP" suffix in the part number explicitly denotes this LSSOP-30 variant, and the "#V0" indicates tray packaging. This package balances I/O density, thermal performance, and manufacturability for mid-complexity industrial control boards.
What is the operating temperature range certified for the R5F101ADASP#V0?
The R5F101ADASP#V0 is rated for industrial operation from –40°C to +85°C, as confirmed by the "D" suffix in its part number per Renesas RL78/G13 documentation. This qualification meets JEDEC JESD22-A104 standards and supports deployment in factory floors, outdoor utility enclosures, and HVAC systems where ambient extremes demand robust silicon behavior without derating.
Which serial communication interfaces are integrated into the R5F101ADASP#V0?
The R5F101ADASP#V0 integrates multiple serial interfaces: up to 2 UART channels (with LIN support), up to 2 CSI channels (SPI-compatible), and up to 3 I²C channels. These are implemented via multiplexed port pins such as P10/SCK00/SCL00 and P11/SI00/RxD0/SDA00, allowing flexible allocation across debugging, sensor interfacing, and host communication without external level shifters or protocol converters.
