FAQ
What is the maximum operating frequency and performance rating of the R5F101LHDFB#30?
The R5F101LHDFB#30 operates at up to 32 MHz with a measured performance of 41 DMIPS. Its RL78 CPU core achieves this using a 3-stage pipeline and supports dynamic clock switching between high-speed (32 MHz) and ultra-low-speed (32.768 kHz) modes. This enables deterministic real-time response in motor control while minimizing power in sleep states - a key advantage in the R5F101LHDFB#30 for time-critical embedded designs.
Does the R5F101LHDFB#30 include data flash memory?
No, the R5F101LHDFB#30 does not include data flash memory. As indicated by the "101" prefix in the Renesas part numbering scheme, this variant provides 192 KB of code flash and 16 KB of RAM but omits the 4–8 KB data flash found in "100" series parts like R5F100LHDFB#30. System designers must implement parameter storage using emulated EEPROM in code flash or external serial memory - a confirmed specification for the R5F101LHDFB#30.
What package type and pin count does the R5F101LHDFB#30 use?
The R5F101LHDFB#30 uses a 64-pin LFQFP package with 10 × 10 mm body size and 0.5 mm lead pitch (Renesas code PLQP0064KF-A). The "FB" suffix in the part number explicitly denotes LFQFP-0.5mm, distinguishing it from LQFP-0.65mm ("FA") and QFN variants. This package supports standard surface-mount reflow profiles and provides adequate thermal dissipation for continuous 32 MHz operation - a verified mechanical specification for the R5F101LHDFB#30.
What is the operating temperature range for the R5F101LHDFB#30?
The R5F101LHDFB#30 is rated for industrial operation from −40°C to +85°C (D-grade), as confirmed by Renesas' official ordering information and datasheet Section 1.1. It does not support the extended −40°C to +105°C (G-grade) range offered by some RL78/G13 variants. This temperature grade ensures reliability in factory automation, HVAC controls, and outdoor metering - critical thermal validation for the R5F101LHDFB#30 in demanding environments.
Which serial communication interfaces are supported by the R5F101LHDFB#30?
The R5F101LHDFB#30 supports UART/LIN (up to 4 channels), I²C/Simplified I²C (up to 10 channels), and CSI (SPI-compatible, up to 8 channels), all implemented in hardware with DMA support. These interfaces share I/O pins and are configured via peripheral enable registers - no external transceivers needed for basic LIN or I²C. This multi-protocol capability is fully documented in the R5F101LHDFB#30 datasheet and enables flexible connectivity in sensor fusion and human-machine interface designs.
