Product details
Overview
R5F101ADASP#50 from Renesas is a 32-bit RL78/G13 microcontroller with 32 KB flash memory, 2 KB RAM, and no data flash, designed for industrial embedded control in 30-pin LSSOP packages. It operates from 1.6 V to 5.5 V, delivers 41 DMIPS at 32 MHz, supports ultra-low-power modes (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#50 datasheet, R5F101ADASP#50 pinout, R5F101ADASP#50 application, or R5F101ADASP#50 equivalent, key selection criteria include its industrial-grade temperature range (–40°C to +85°C), absence of data flash, LSSOP-30 package compatibility, and support for low-power sensor interface and motor control firmware deployment.
Technical Context
The R5F101ADASP#50 implements the RL78 CPU core with CISC architecture and 3-stage pipeline, enabling instruction execution times from 0.03125 μs (32 MHz) to 30.5 μs (32.768 kHz). It features on-chip power-on-reset, voltage detector with 14-level LVD, and HALT/STOP/SNOOZE low-power modes optimized for battery-powered industrial nodes.
Its peripheral set includes up to 16-channel 16-bit timer, calendar-based RTC with alarm and correction, 10-bit A/D converter with internal 1.45 V reference and temperature sensor, and serial interfaces (UART/LIN, I²C, CSI) supporting multi-protocol communication in space-constrained designs.

FAQ
What is the operating temperature range for the R5F101ADASP#50?
The R5F101ADASP#50 is rated for industrial operation from –40°C to +85°C, as indicated by the 'D' suffix in its part number. This qualification ensures reliable performance in factory automation, HVAC, and outdoor metering environments where ambient temperatures exceed consumer-grade limits. The device maintains full functionality-including ADC accuracy, oscillator stability, and flash programming-across this full range.
Does the R5F101ADASP#50 include data flash memory?
No, the R5F101ADASP#50 does not include data flash memory. As confirmed by Renesas' part numbering convention ('101' denotes no data flash), this variant provides 32 KB of code flash and 2 KB of RAM only. Applications requiring non-volatile parameter storage must use an alternative such as R5F100ADASP#50 (which includes 4 KB data flash) or implement external EEPROM/FRAM.
Which package type does the R5F101ADASP#50 use?
The R5F101ADASP#50 uses a 30-pin plastic LSSOP package (7.62 mm body width, 0.65-mm lead pitch), identified by the 'SP' suffix and documented in Renesas' PLSP0030JB-B package code. This gull-wing surface-mount package supports automated assembly and offers better thermal performance than TSSOP variants while maintaining compact board area.
Can the R5F101ADASP#50 operate from a 1.8 V supply?
Yes, the R5F101ADASP#50 supports operation from 1.6 V to 5.5 V, including 1.8 V nominal supplies. At 1.8 V, it achieves reduced maximum clock frequency (typically ≤16 MHz per electrical characteristics), but retains full peripheral functionality including ADC, timers, and serial interfaces. This enables direct integration with 1.8 V logic families and low-voltage battery systems without level-shifting.
What debug interface is supported by the R5F101ADASP#50?
The R5F101ADASP#50 supports single-wire debug (SWD) via the TOOLRxD pin (shared with P11), enabling full on-chip debugging, flash programming, and real-time trace without requiring additional pins or headers. This interface is compatible with Renesas E2 studio and third-party tools using the Renesas Debug Adapter (RDA) or CMSIS-DAP compliant probes.
