Product details
Overview
R5F101ADASP#10 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 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 - deployed in battery-powered sensor nodes and smart metering endpoints.
For engineers reviewing the R5F101ADASP#10 datasheet, R5F101ADASP#10 pinout, R5F101ADASP#10 application, or R5F101ADASP#10 equivalent, key selection criteria include its LSSOP-30 package, industrial temperature grade (D), absence of data flash, 32 KB code flash size, and support for HALT/STOP/SNOOZE low-power modes with on-chip LVD and POR.
Technical Context
The R5F101ADASP#10 implements the RL78 CPU core with CISC architecture and 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 four register banks of eight 8-bit registers each.
Power management includes an on-chip voltage detector (LVD) with 14 selectable interrupt/reset levels and a power-on-reset (POR) circuit. The device supports background operation during data flash rewriting (though R5F101x variants lack data flash), and features DMA with 2 channels transferring between SFR and internal RAM in just 2 clocks per 8/16-bit transfer.

FAQ
What is the maximum operating frequency and corresponding performance of the R5F101ADASP#10?
The R5F101ADASP#10 operates at up to 32 MHz, achieving 41 DMIPS (Dhrystone MIPS) performance. This speed is enabled by the RL78 CPU's 3-stage pipeline and high-speed on-chip oscillator. At 32 MHz, the minimum instruction execution time is 0.03125 μs - sufficient for real-time motor control loops, sensor fusion, and protocol stack processing in resource-constrained designs. The R5F101ADASP#10 maintains this performance across its full 1.6 V to 5.5 V supply range.
Does the R5F101ADASP#10 include data flash memory?
No, the R5F101ADASP#10 does not include data flash memory. As indicated by the "101" prefix in the part number (per Renesas' naming convention), this variant provides only code flash memory - 32 KB in this case - with no dedicated data flash. Applications requiring nonvolatile parameter storage must implement wear-leveling in code flash or use external EEPROM/FRAM. In contrast, R5F100x variants (e.g., R5F100ADASP#10) include 4 KB of data flash.
What package type and pin count does the R5F101ADASP#10 use?
The R5F101ADASP#10 uses a 30-pin plastic LSSOP (Low-Profile Small Outline Package) with 0.65-mm pitch and JEDEC MS-013AC footprint. Its dimensions are 9.9 mm × 4.4 mm × 1.75 mm max height. This package is optimized for automated pick-and-place assembly and offers good thermal dissipation for industrial ambient conditions. Pin compatibility is maintained across all R5F101xASP#10 variants in the same pin-count group.
What low-power modes are supported by the R5F101ADASP#10, and what is the lowest current consumption?
The R5F101ADASP#10 supports HALT, STOP, and SNOOZE low-power modes. In STOP mode with only RTC and LVD active, it draws just 0.57 μA - verified at VDD = 1.8 V and TA = 25°C. HALT mode consumes 66 μA/MHz, scaling linearly with clock frequency. These modes are controlled via dedicated system control registers and support fast wake-up (sub-1 μs from HALT), making the R5F101ADASP#10 ideal for duty-cycled sensor applications where average current dictates battery lifetime.
Is the R5F101ADASP#10 qualified for industrial temperature operation?
Yes, the R5F101ADASP#10 is rated for industrial temperature operation from -40°C to +85°C, as denoted by the "D" suffix in its part number. This qualification covers all electrical specifications including flash programming, ADC accuracy, oscillator stability, and I/O drive strength across the full range. It meets JEDEC JESD22-A104 reliability standards for temperature cycling and is suitable for deployment in factory floors, outdoor utility equipment, and commercial HVAC systems.
