Product details
Overview
R5F101ACDSP#30 from Renesas is a 30-pin, 16 KB flash, data-flash-free RL78/G13 16-bit microcontroller with ultra-low power consumption (66 μA/MHz active, 0.57 μA RTC+LVD), 1.6–5.5 V operation, and 32 MHz max CPU speed delivering 41 DMIPS - deployed in battery-powered industrial sensors and smart metering endpoints.
For engineers reviewing the R5F101ACDSP#30 datasheet, R5F101ACDSP#30 pinout, R5F101ACDSP#30 application, or R5F101ACDSP#30 equivalent, key selection criteria include its LSSOP-30 package, absence of on-chip data flash, -40°C to +85°C industrial temperature grade (D), and integrated 10-bit ADC with 6-channel analog input support.
Technical Context
The R5F101ACDSP#30 implements the RL78 CPU core with CISC architecture and 3-stage pipeline, supporting variable instruction execution time from 0.03125 μs (@32 MHz) to 30.5 μs (@32.768 kHz). It integrates a high-accuracy ±1.0% on-chip oscillator and hardware multiplier/divider for real-time control math.
Its peripheral set includes one 12-bit interval timer, one real-time clock with calendar/alarm functions, eight 16-bit timers, three I²C channels, two UART/LIN interfaces, two CSI (SPI-compatible) channels, and an 8/10-bit A/D converter with internal 1.45 V reference and temperature sensor.

FAQ
What is the operating temperature range for the R5F101ACDSP#30?
The R5F101ACDSP#30 is rated for industrial operation from -40°C to +85°C (suffix 'D'), making it suitable for deployment in harsh environments such as factory floors, outdoor utility meters, and HVAC equipment where ambient thermal stability cannot be guaranteed.
Does the R5F101ACDSP#30 include on-chip data flash memory?
No, the R5F101ACDSP#30 does not include data flash memory - this is indicated by the '1' in the third digit of the part number (R5F101AC...). In contrast, R5F100AC... variants include 4 KB data flash. The R5F101ACDSP#30 relies on external EEPROM or FRAM if non-volatile parameter storage is required.
Which package type does the R5F101ACDSP#30 use?
The R5F101ACDSP#30 uses a 30-pin plastic LSSOP package (7.62 mm, 0.65-mm pitch), identified by the 'SP' suffix and #30 tray packaging specification. This surface-mount package offers robust solder joint reliability and is compatible with standard reflow processes used in high-volume manufacturing.
How many analog input channels does the R5F101ACDSP#30 support?
The R5F101ACDSP#30 supports up to 6 analog input channels (ANI0–ANI2 and ANI18 among others), with 10-bit resolution and selectable reference sources. Channel mapping is confirmed in the RL78/G13 datasheet Section 1.3 Pin Configuration and Section 24.3 A/D Converter.
Can the R5F101ACDSP#30 operate without an external crystal?
Yes, the R5F101ACDSP#30 operates fully from its on-chip high-speed oscillator (selectable 1–32 MHz, ±1.0% accuracy), eliminating the need for external crystals or resonators. This reduces BOM cost, PCB area, and startup time - critical for cost-sensitive and battery-powered designs.
