FAQ
What is the maximum clock frequency supported by the R5F101ADDSP#V0?
The R5F101ADDSP#V0 supports a maximum operating frequency of 32 MHz using its high-speed on-chip oscillator. At this speed, it achieves 41 DMIPS performance. The oscillator accuracy is ±1.0% over the full industrial temperature range (-40°C to +85°C) and supply voltage (1.8–5.5 V), eliminating need for external crystals in many applications. This specification is confirmed in the R01DS0131EJ0380 datasheet Section 1.1.
Does the R5F101ADDSP#V0 include on-chip data flash memory?
No, the R5F101ADDSP#V0 does not include on-chip data flash memory. Per the RL78/G13 family naming convention (Section 1.2 of R01DS0131EJ0380), the "101" prefix indicates no data flash, distinguishing it from "100"-series parts like R5F100ADDSP#V0 which include 4 KB. Firmware must use external EEPROM or FRAM if nonvolatile parameter storage is required.
What package type and pin count does the R5F101ADDSP#V0 use?
The R5F101ADDSP#V0 uses a 32-pin plastic LSSOP package (7.62 mm, 0.65-mm pitch), identified by the "SP" suffix and "#V0" tray packaging code. This surface-mount package is optimized for compact industrial PCBs and supports reflow soldering. Pin configuration matches the RL78/G13 32-pin variant defined in Figure 1-1 and Table 1-1 of the datasheet.
What is the operating temperature range for the R5F101ADDSP#V0?
The R5F101ADDSP#V0 is rated for industrial operation from -40°C to +85°C, indicated by the "D" suffix in its part number per Figure 1-1 of R01DS0131EJ0380. This qualification covers extended thermal cycling, humidity, and voltage variation typical in factory automation, building controls, and outdoor equipment - exceeding commercial-grade (A: -40°C to +85°C) and matching industrial reliability requirements.
Which serial communication interfaces are available on the R5F101ADDSP#V0?
The R5F101ADDSP#V0 integrates UART/UART-LIN (up to 4 channels), I²C/Simplified I²C (up to 10 channels), and CSI (Simplified SPI, up to 8 channels). All are configurable via software registers and share pins with GPIO or analog functions. No external transceivers are needed for basic point-to-point UART or I²C communication, though RS-485 or CAN require external drivers - the R5F101ADDSP#V0 itself does not include CAN PHY.
