Renesas R5F100PGGFA#X0

Overview

R5F100PGGFA#X0 from Renesas is a 100-pin LQFP-0.5mm-pitch, industrial-grade (−40°C to +105°C) RL78/G13 16-bit MCU with 128 KB flash, 8 KB data flash, 12 KB RAM, 32 MHz max CPU speed, and integrated RTC, 10-bit ADC (26 channels), UART, I²C, CSI, and ultra-low-power STOP mode (0.57 μA). It targets battery-powered industrial sensors and embedded control systems requiring long runtime and high reliability.

For engineers reviewing the R5F100PGGFA#X0 datasheet, R5F100PGGFA#X0 pinout, R5F100PGGFA#X0 application, or R5F100PGGFA#X0 equivalent, key selection criteria include its G-grade temperature rating, on-chip data flash rewrite endurance (1M cycles), real-time clock calendar function, 10-bit ADC input count and reference options, and LQFP-100 (0.5 mm pitch) package compatibility with automated SMT assembly.

Technical Context

The R5F100PGGFA#X0 implements the RL78 CPU core with 3-stage pipeline, supporting instruction execution times from 0.03125 μs (32 MHz HS mode) to 30.5 μs (32.768 kHz subsystem clock). It integrates a 12-bit interval timer, calendar-mode RTC with alarm and clock correction, and a dedicated low-speed on-chip oscillator for watchdog operation.

Its peripheral set includes up to 26-channel 10-bit ADC with internal 1.45 V reference and temperature sensor, 3–10-channel I²C/Simplified I²C, 2–4-channel UART/LIN, and 2–8-channel CSI (SPI-compatible serial interface), all configurable via memory-mapped registers and supported by DMA (4-channel).

FAQ

What is the operating temperature range for the R5F100PGGFA#X0?

The R5F100PGGFA#X0 is rated for industrial operation from −40°C to +105°C (G-grade), validated across its full voltage range (1.6–5.5 V) and all specified peripheral functions, making it suitable for harsh environments like factory floors or outdoor utility installations.

Does the R5F100PGGFA#X0 support in-system programming via standard interfaces?

Yes, the R5F100PGGFA#X0 supports on-chip debug and self-programming via its built-in debug interface (using TOOLRxD/TOOLTxD pins), enabling firmware updates and data flash writes without external programmers - essential for field-upgradable devices.

How many ADC channels does the R5F100PGGFA#X0 provide, and what reference options are available?

The R5F100PGGFA#X0 integrates a 10-bit ADC with up to 26 analog input channels. It supports external reference voltages or the internal 1.45 V reference, and includes a factory-calibrated temperature sensor accessible as an ADC input channel.

Can the R5F100PGGFA#X0 operate reliably at 1.6 V supply voltage?

Yes, the R5F100PGGFA#X0 guarantees full functionality-including 32 MHz operation, ADC conversion, and RTC-down to 1.6 V VDD, enabling direct use with primary lithium or two-cell alkaline batteries without regulation.

Is the R5F100PGGFA#X0 pin-compatible with other RL78/G13 variants in the same package?

Yes, all RL78/G13 devices in the 100-pin LQFP-0.65mm (PLQP0100JC-A) package share identical pinouts and electrical characteristics; R5F100PGGFA#X0 can be substituted with other G-grade 100-pin variants (e.g., R5F100PHGFA#X0) without PCB changes.
