Product details
Overview
R5F101AADSP#V0 from Renesas is a 30-pin LSSOP-packaged RL78/G13 16-bit microcontroller with 16 KB flash, 2 KB RAM, and no data flash memory, designed for ultra-low-power industrial control applications operating from 1.6 V to 5.5 V, delivering 41 DMIPS at 32 MHz with 66 μA/MHz active current and RTC+LVD retention at 0.57 μA.
For engineers reviewing the R5F101AADSP#V0 datasheet, R5F101AADSP#V0 pinout, R5F101AADSP#V0 application, or R5F101AADSP#V0 equivalent, key selection criteria include its 30-pin LSSOP-30 package, absence of on-chip data flash, industrial-grade −40°C to +85°C temperature rating (D suffix), and support for SNOOZE mode, 10-bit ADC (6 channels), and dual UART/LIN interfaces in compact embedded systems.
Technical Context
The R5F101AADSP#V0 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 10-bit A/D converter with internal 1.45 V reference and temperature sensor, plus real-time clock with calendar, alarm, and correction functions.
Power management includes HALT, STOP, and SNOOZE modes, on-chip POR and 14-level LVD, and DMA controller with 2 channels. Serial interfaces comprise up to 4 UART/LIN channels, 3–10 I²C/Simplified I²C channels, and 2–8 CSI (SPI-compatible) channels - all confirmed for this 30-pin variant per RL78/G13 family documentation.

Does the R5F101AADSP#V0 include data flash memory?
No, the R5F101AADSP#V0 does not include data flash memory. Per the RL78/G13 part numbering convention, the "101" prefix indicates no data flash, distinguishing it from "100" variants like R5F100AADSP#V0 which include 4 KB. The R5F101AADSP#V0 provides 16 KB code flash only, with RAM-based data storage during operation.
What package type and pin count does the R5F101AADSP#V0 use?
The R5F101AADSP#V0 uses a 30-pin plastic LSSOP package (7.62 mm, 0.65-mm pitch), identified by Renesas code PLSP0030JB-B and ordering suffix #V0. This surface-mount package is RoHS-compliant, JEDEC-standardized, and optimized for automated assembly in space-constrained industrial PCBs.
What is the operating temperature range for the R5F101AADSP#V0?
The R5F101AADSP#V0 is rated for industrial operation from −40°C to +85°C, indicated by the "D" suffix in its part number family. This temperature grade is validated per JEDEC JESD22-A108 and ensures reliable functionality in factory automation, building controls, and outdoor-rated equipment without derating.
Which serial communication interfaces are supported by the R5F101AADSP#V0?
The R5F101AADSP#V0 supports UART/LIN (2 channels), I²C/Simplified I²C (3 channels), and CSI (SPI-compatible, 2 channels) - all confirmed for the 30-pin LSSOP variant in the RL78/G13 datasheet. These interfaces operate across the full voltage and temperature range, with LIN compliance achieved via UART hardware with software-controlled break detection.
