Renesas R5F101PGDFA#V0

Overview

R5F101PGDFA#V0 from Renesas is a 100-pin LQFP-0.65mm, industrial-grade RL78/G13 16-bit microcontroller with 64 KB flash, 4 KB data flash, 4 KB RAM, and operation from -40°C to +85°C. It delivers 41 DMIPS at 32 MHz, features ultra-low power consumption (66 μA/MHz active, 0.57 μA in RTC+LVD mode), and integrates 16-bit timers, 10-bit ADC (16 channels), UART/LIN, I²C, and SPI interfaces for embedded control in resource-constrained systems.

For engineers reviewing the R5F101PGDFA#V0 datasheet, R5F101PGDFA#V0 pinout, R5F101PGDFA#V0 application, or R5F101PGDFA#V0 equivalent, key selection criteria include its 100-pin LQFP package, absence of on-chip data flash (R5F101x series), industrial temperature rating, and compatibility with Renesas' RL78 development ecosystem including CS+ and e² studio.

Technical Context

The R5F101PGDFA#V0 implements the RL78 CPU core with CISC architecture and 3-stage pipeline, supporting instruction execution times from 0.03125 μs (32 MHz high-speed mode) to 30.5 μs (32.768 kHz subsystem clock). It uses a single 1.6–5.5 V supply and includes dedicated low-power modes-HALT, STOP, and SNOOZE-with on-chip POR and 14-level LVD for robust system reset management.

Its peripheral set includes up to 16 channels of 16-bit timer, one real-time clock with calendar/alarm/correction, one watchdog timer, 10-bit A/D converter with internal 1.45 V reference and temperature sensor, and multiple serial interfaces: 2–4 UART/LIN channels, 3–10 I²C/Simplified I²C channels, and 2–8 CSI (SPI-compatible) channels-all configurable via register-based control without external glue logic.

FAQ

What is the maximum operating frequency and corresponding performance of the R5F101PGDFA#V0?

The R5F101PGDFA#V0 operates at up to 32 MHz and delivers 41 DMIPS of processing performance. This is achieved using the RL78 CPU core's 3-stage pipeline and high-speed on-chip oscillator. The device maintains this performance across its full 1.6–5.5 V supply range and industrial temperature grade (-40°C to +85°C), making it suitable for deterministic real-time control tasks in demanding environments.

Does the R5F101PGDFA#V0 include on-chip data flash memory?

No, the R5F101PGDFA#V0 does not include on-chip data flash memory. As indicated by the "101" prefix in its part number per Renesas' naming convention, this variant omits the 4 KB data flash found in R5F100x-series counterparts. Designers requiring non-volatile parameter storage must use external EEPROM or utilize the code flash with wear-leveling software - a trade-off accepted for lower cost and reduced complexity in fixed-function applications.

What package type and pin count does the R5F101PGDFA#V0 use?

The R5F101PGDFA#V0 uses a 100-pin plastic LQFP package with 0.65 mm pitch and dimensions of 14 × 20 mm. The "#V0" suffix confirms tray packaging, and the "FA" in the part number denotes the LQFP-0.65mm variant. This package provides robust thermal performance and mechanical stability for industrial PCB assembly, with validated pinout documented in Renesas datasheet R01DS0131EJ0380.

Which serial communication interfaces are supported by the R5F101PGDFA#V0?

The R5F101PGDFA#V0 supports UART/LIN (up to 4 channels), I²C/Simplified I²C (up to 10 channels), and CSI (SPI-compatible, up to 8 channels). These interfaces share pins via multiplexing - for example, P10 serves as both SCK00 (SPI clock) and SCL00 (I²C clock), while P11 and P12 support SI00/SO00, RxD0/TxD0, and SDA00 simultaneously. Configuration is register-controlled, enabling dynamic protocol selection without hardware changes.

What low-power modes are available on the R5F101PGDFA#V0, and what is the lowest current draw?

The R5F101PGDFA#V0 supports HALT, STOP, and SNOOZE low-power modes. In STOP mode with only the real-time clock (RTC) and low-voltage detector (LVD) active, it draws just 0.57 μA - verified across -40°C to +85°C. This enables multi-year battery operation in sensor nodes and metering devices. Wake-up sources include external interrupts, RTC alarm, and analog comparator events, all configurable without exiting low-power state.
