Product details
Overview
R5F101FHDFP#V0 from Renesas is a 44-pin LQFP-packaged RL78/G13 16-bit microcontroller with 96 KB flash, 8 KB data flash, 8 KB RAM, 16 MHz max CPU speed, and ultra-low-power operation (66 μA/MHz active, 0.57 μA RTC+LVD). It targets battery-powered industrial sensors and smart metering interfaces requiring robust timing, analog sensing, and LIN bus communication.
For engineers reviewing the R5F101FHDFP#V0 datasheet, R5F101FHDFP#V0 pinout, R5F101FHDFP#V0 application, or R5F101FHDFP#V0 equivalent, key selection criteria include its 44-pin LQFP-0.8mm package, absence of on-chip data flash (R5F101x series), -40°C to +85°C industrial temperature grade (D suffix), and integrated LIN-capable UART channels for automotive body electronics and HVAC control systems.
Technical Context
The R5F101FHDFP#V0 implements the RL78 CPU core with 3-stage pipeline, supporting instruction execution times from 0.03125 μs (32 MHz) down to 30.5 μs (32.768 kHz), enabling dynamic power/performance scaling. Its memory subsystem includes 96 KB code flash with 1 KB block erase, 8 KB RAM, and no embedded data flash-relying instead on external EEPROM or flash for nonvolatile parameter storage.
Peripheral integration includes dual UART/LIN modules (one with LIN physical layer support), up to 26-channel 10-bit ADC with internal 1.45 V reference and temperature sensor, real-time clock with calendar and alarm, and 16-bit timers with interval and watchdog functions-all operating across 1.6–5.5 V supply and -40°C to +85°C ambient range.

FAQ
What is the flash memory configuration of the R5F101FHDFP#V0?
The R5F101FHDFP#V0 contains 96 KB of on-chip code flash memory organized in 1 KB blocks, with support for block erase prohibition and self-programming. Unlike the R5F100x series, it does not include embedded data flash memory - nonvolatile parameter storage must be implemented externally or via code flash emulation techniques. This configuration reduces die size and cost while maintaining full compatibility with RL78/G13 development tools and firmware libraries.
Does the R5F101FHDFP#V0 support LIN bus communication?
Yes, the R5F101FHDFP#V0 supports LIN bus communication through its UART0 and UART1 modules, both of which include LIN-specific features such as automatic sync-break detection, checksum generation, and configurable baud rates compliant with LIN 2.2A specifications. The device operates as a LIN slave node and requires an external LIN transceiver (e.g., TLE7259-2GE) for physical layer compliance - no internal LIN driver is integrated.
What is the operating temperature range for the R5F101FHDFP#V0?
The R5F101FHDFP#V0 is rated for industrial operation from -40°C to +85°C, indicated by the 'D' suffix in its part number family. This qualification covers all specified electrical characteristics including flash programming, ADC accuracy, oscillator stability, and peripheral timing - making it suitable for deployment in factory automation equipment, outdoor utility meters, and commercial HVAC systems without derating.
How many analog input channels does the R5F101FHDFP#V0 support?
The R5F101FHDFP#V0 supports up to 26 analog input channels via its 10-bit successive-approximation ADC. These channels are mapped across multiple port pins including P20–P27, P13–P17, and P30–P37, with selectable reference sources (AVREFP/AVREFM, internal 1.45 V, or VDD). The ADC also integrates a calibrated on-chip temperature sensor usable for ambient monitoring without external components.
Is the R5F101FHDFP#V0 pin-compatible with other RL78/G13 devices in 44-pin LQFP?
Yes, the R5F101FHDFP#V0 shares identical pinout and package dimensions (44-pin LQFP, 10 × 10 mm, 0.8-mm pitch) with all other RL78/G13 devices in the same package variant, including R5F100x and R5F101x families. Pin functions are fully compatible across these variants, enabling hardware reuse and migration paths - for example, upgrading from R5F101FHDFP#V0 to R5F100FHDFP#V0 requires only firmware update to enable data flash usage.
