Renesas R5F101PHAFB#V0

Overview

R5F101PHAFB#V0 from Renesas is a 100-pin LFQFP (0.5-mm pitch), 16-bit RL78/G13 microcontroller with no data flash, 96 KB code flash, 8 KB RAM, and industrial-grade operation up to +105°C - designed for low-power sensor nodes, motor control interfaces, and smart appliance subsystems requiring RTC, ADC, and LIN-capable UART.

For engineers reviewing the R5F101PHAFB#V0 datasheet, R5F101PHAFB#V0 pinout, R5F101PHAFB#V0 application, or R5F101PHAFB#V0 equivalent, key selection criteria include its 96 KB flash / 8 KB RAM configuration, 100-pin LFQFP-0.5 mm package, absence of on-chip data flash, support for 32 MHz max CPU clock, and integrated real-time clock with calendar function.

Technical Context

The R5F101PHAFB#V0 implements the RL78 CPU core with 3-stage pipeline CISC architecture, enabling instruction execution times from 0.03125 μs (32 MHz) to 30.5 μs (32.768 kHz). It integrates a 10-bit A/D converter with up to 26 channels, 16-bit timers (12 channels), and a hardware real-time clock with alarm and correction functions.

Power management includes HALT, STOP, and SNOOZE modes, achieving 66 μA/MHz active current and 0.57 μA in RTC+LVD-only mode. Its serial interface set comprises up to 4 UART/LIN channels, 10 I²C/Simplified I²C channels, and 8 CSI (SPI-compatible) channels - all configurable without external components.

FAQ

What is the maximum operating frequency of the R5F101PHAFB#V0?

The R5F101PHAFB#V0 supports a maximum CPU clock frequency of 32 MHz, delivering 41 DMIPS performance. This is achieved using the high-speed on-chip oscillator with ±1.0% accuracy across 1.8–5.5 V and −20°C to +85°C - and remains fully functional at the full −40°C to +105°C industrial range with appropriate derating.

Does the R5F101PHAFB#V0 include on-chip data flash memory?

No, the R5F101PHAFB#V0 does not include on-chip data flash memory. Per Renesas part numbering convention, the "101" prefix indicates no data flash, distinguishing it from "100"-series variants like R5F100PHAFB#V0 which integrate 8 KB data flash. Code flash remains 96 KB in both cases.

Which package type and pin count does the R5F101PHAFB#V0 use?

The R5F101PHAFB#V0 uses a 100-pin LFQFP package with 0.5-mm lead pitch and 14 × 14 mm body size (RENESAS code PLQP0100KE-A). The "FB" suffix in the part number explicitly denotes LFQFP, and "#V0" indicates tray packaging - confirmed in Table 1-1, Page 12 of the RL78/G13 datasheet R01DS0131EJ0380.

What is the operating temperature range certified for the R5F101PHAFB#V0?

The R5F101PHAFB#V0 is rated for industrial operation from −40°C to +105°C. This is indicated by the "G" suffix in its full family designation (R5F101P**G**AFB#V0), corresponding to the "G: Industrial applications, operating ambient temperature: −40°C to +105°C" classification in Figure 1-1 of the datasheet.

Does the R5F101PHAFB#V0 support LIN bus communication?

Yes, the R5F101PHAFB#V0 supports LIN bus communication via its UART peripherals. Specifically, UART0 and UART1 include hardware LIN 2.2 and SAE J2602 protocol support - including break detection, sync field handling, and checksum generation - enabling direct connection to LIN transceivers without software bit-banging.
