Product details
Overview
R5F101ADASP#70 from Renesas is a 32-bit RL78/G13 microcontroller with 32 KB flash memory, 2 KB RAM, and no data flash, designed for industrial applications (−40°C to +85°C) in LSSOP-30 package. It delivers 41 DMIPS at 32 MHz, features ultra-low power consumption (66 μA/MHz active, 0.57 μA RTC+LVD), and integrates 10-bit ADC (6 channels), UART, I²C, SPI, 16-bit timers, and real-time clock.
For engineers reviewing the R5F101ADASP#70 datasheet, R5F101ADASP#70 pinout, R5F101ADASP#70 application, or R5F101ADASP#70 equivalent, key selection criteria include its industrial temperature grade, absence of data flash, LSSOP-30 footprint, 30-pin I/O count, and support for low-power sensor interface and motor control firmware.
Technical Context
The R5F101ADASP#70 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 subsystem clock). It operates across 1.6–5.5 V supply and includes on-chip power-on-reset, voltage detector (14-level LVD), and HALT/STOP/SNOOZE low-power modes.
It integrates 8-channel 16-bit timers, one 12-bit interval timer, one calendar-capable real-time clock with alarm and correction, and a watchdog timer running on dedicated low-speed oscillator. Serial interfaces include up to 4 UART/LIN, 10 I²C/Simplified I²C, and 8 CSI (SPI-compatible) channels - all configurable per pin assignment in the LSSOP-30 layout.

FAQ
What is the maximum operating frequency and performance of the R5F101ADASP#70?
The R5F101ADASP#70 operates at up to 32 MHz with a peak performance of 41 DMIPS. Its RL78 CPU core achieves this using a 3-stage pipeline and high-accuracy on-chip oscillator (±1.0% over −20 to +85°C). The minimum instruction execution time varies from 0.03125 μs in high-speed mode to 30.5 μs in ultra-low-speed mode (32.768 kHz), enabling flexible power/performance tuning in the R5F101ADASP#70.
Does the R5F101ADASP#70 include data flash memory?
No, the R5F101ADASP#70 does not include data flash memory. As indicated by the '1' in the part number (per Renesas RL78/G13 naming convention), it provides 32 KB of code flash and 2 KB of RAM only. For applications requiring non-volatile parameter storage, the pin-compatible R5F100ADASP#70 (with 4 KB data flash) is the direct alternative. This distinction is confirmed in the RL78/G13 datasheet memory matrix on page 2.
What package type and pin count does the R5F101ADASP#70 use?
The R5F101ADASP#70 uses a 30-pin plastic LSSOP package (7.62 mm × 9.9 mm, 0.65 mm pitch), identified by the 'SP' suffix and '#70' tray packaging code. This matches the 'A' prefix in the ordering number format shown in Table 1-1 of the datasheet. The LSSOP-30 footprint is optimized for industrial PCBs requiring moderate I/O density and reflow compatibility without thermal pad constraints.
What is the operating temperature range for the R5F101ADASP#70?
The R5F101ADASP#70 is rated for industrial operation from −40°C to +85°C, as designated by the 'D' suffix in its part number per Renesas RL78/G13 nomenclature. This distinguishes it from consumer-grade ('A') and extended industrial ('G', −40°C to +105°C) variants. All electrical specifications-including flash endurance, ADC accuracy, and oscillator stability-are guaranteed across this full industrial temperature range.
Which serial communication interfaces are supported by the R5F101ADASP#70?
The R5F101ADASP#70 supports UART/LIN (up to 4 channels), I²C/Simplified I²C (up to 10 channels), and CSI (SPI-compatible serial interface, up to 8 channels). These are implemented via multiplexed GPIO pins in the LSSOP-30 package, with specific assignments documented in the pin configuration table (e.g., P10/P11 for SCK00/RxD0/SDA00). No CAN or USB interfaces are integrated in the R5F101ADASP#70.
