Renesas R5F101PGAFA#30

Overview

R5F101PGAFA#30 from Renesas is a 32-bit RL78/G13 microcontroller with no data flash memory, housed in a 100-pin LQFP (0.65-mm pitch) package, operating from 1.6 V to 5.5 V, delivering 41 DMIPS at 32 MHz and featuring ultra-low power consumption (66 μA/MHz active, 0.57 μA RTC+LVD mode). It targets battery-powered industrial sensors and low-power HMI control units requiring integrated analog peripherals and robust real-time operation.

For engineers reviewing the R5F101PGAFA#30 datasheet, R5F101PGAFA#30 pinout, R5F101PGAFA#30 application, or R5F101PGAFA#30 equivalent, key selection criteria include its 64 KB code flash, 4 KB RAM, 10-bit 26-channel ADC, RTC with calendar/alarm, and support for LIN-bus UART - all within an industrial-grade −40°C to +85°C temperature range.

Technical Context

The R5F101PGAFA#30 implements the RL78 CPU core with CISC architecture and 3-stage pipeline, enabling instruction execution times from 0.03125 μs (32 MHz high-speed mode) to 30.5 μs (32.768 kHz subsystem clock). It integrates a 12-bit interval timer, 16-bit timer array (12 channels), and real-time clock with calendar function and clock correction.

Its peripheral set includes UART/LIN (2 channels), I²C (up to 10 channels), CSI (SPI-compatible, 2–8 channels), DMA controller (2 channels), 16×16-bit multiplier/32-bit divider, and on-chip voltage detector with 14-level LVD interrupt/reset selection - all optimized for deterministic real-time control in resource-constrained embedded systems.

FAQ

What is the flash memory configuration of the R5F101PGAFA#30?

The R5F101PGAFA#30 contains 64 KB of on-chip code flash memory and no data flash memory. This configuration supports firmware storage and self-programming via boot swap and flash shield window functions, but excludes dedicated non-volatile parameter storage - making it optimal for fixed-function deployments where configuration persistence is handled externally or via code flash emulation.

Does the R5F101PGAFA#30 support LIN bus communication?

Yes, the R5F101PGAFA#30 supports LIN bus communication through its UART peripheral, which is explicitly LIN-bus compatible per the RL78/G13 datasheet. One of its two UART channels (e.g., UART0) can be configured for LIN 2.2 protocol operation, enabling direct connection to LIN transceivers for automotive body electronics or industrial actuator networks without additional protocol translation.

What is the maximum ADC sampling rate achievable with the R5F101PGAFA#30?

The R5F101PGAFA#30's 10-bit ADC supports up to 150 kSPS maximum conversion rate under typical conditions (VDD = 3.3 V, fADCLK = 15 MHz). The actual sustained sampling rate depends on channel count, resolution mode, and trigger source - for example, sequential sampling across 10 channels yields ~15 kSPS per channel with automatic scan and interrupt-on-complete.

Is the R5F101PGAFA#30 pin-compatible with any R5F100x series devices?

Yes, the R5F101PGAFA#30 is pin-compatible with the R5F100PGAFA#30 - both use identical 100-pin LQFP (0.65-mm pitch) packaging and share the same pinout, register map, and peripheral assignment. The only functional difference is the absence of data flash in the R5F101x variant, allowing drop-in replacement where non-volatile parameter storage is not required.

What debug interfaces are supported by the R5F101PGAFA#30?

The R5F101PGAFA#30 supports on-chip debugging via the single-wire debug (SWD) interface using the TOOLnTRST and TOOLRxD pins, compliant with Renesas E1/E20 emulators. It does not support JTAG; SWD enables full breakpoint, watchpoint, and memory access capabilities during development and field firmware updates without requiring additional debug headers or pins.
