Renesas R5F100PLAFA#30

Overview

R5F100PLAFA#30 from Renesas is a 100-pin LQFP (0.65-mm pitch), 512 KB flash, 8 KB data flash, 32 KB RAM RL78/G13 16-bit microcontroller with ultra-low power consumption (66 μA/MHz active, 0.57 μA RTC+LVD mode), 1.6–5.5 V operation, and integrated peripherals including 16-bit timers, 10-bit ADC (26 channels), UART/LIN, I²C, and CSI interfaces - deployed in industrial sensor nodes and battery-powered control modules.

For engineers reviewing the R5F100PLAFA#30 datasheet, R5F100PLAFA#30 pinout, R5F100PLAFA#30 application, or R5F100PLAFA#30 equivalent, key selection criteria include its 100-pin LQFP-0.65mm package, 512 KB code flash with self-programming and flash shield window, real-time clock with calendar/alarm, and support for SNOOZE mode wake-up via serial interface or external interrupt.

Technical Context

The R5F100PLAFA#30 implements the RL78 CPU core with 3-stage pipeline CISC architecture, supporting instruction execution times from 0.03125 μs (32 MHz high-speed oscillator) to 30.5 μs (32.768 kHz subsystem clock). It integrates dual DMA channels enabling 2-clock transfers between SFR and RAM, and a hardware multiplier/divider supporting 16×16→32-bit unsigned/signed multiply and 32÷32→32-bit unsigned divide.

Its peripheral set includes up to 16 channels of 16-bit timer, one 12-bit interval timer, one real-time clock with calendar and clock correction, and three to ten I²C/Simplified I²C channels - all configurable under the same low-power HALT/STOP/SNOOZE operating modes that maintain register retention and selective peripheral wake-up capability.

FAQ

What is the maximum operating frequency and corresponding performance of the R5F100PLAFA#30?

The R5F100PLAFA#30 operates at up to 32 MHz using its high-accuracy on-chip oscillator (±1.0 %), delivering 41 DMIPS. Its RL78 CPU core achieves a minimum instruction execution time of 0.03125 μs in high-speed mode, and supports dynamic clock scaling down to 32.768 kHz for ultra-low-power RTC operation - all within the same R5F100PLAFA#30 device.

Does the R5F100PLAFA#30 support in-system programming and secure firmware updates?

Yes, the R5F100PLAFA#30 supports full in-system programming via its on-chip debug interface and includes flash shield window and boot swap functions. These features allow secure field firmware updates while protecting intellectual property - critical for deployed systems requiring certified R5F100PLAFA#30-based products with validated upgrade paths.

How many analog input channels does the R5F100PLAFA#30 ADC support, and what resolution is available?

The R5F100PLAFA#30 integrates a 10-bit successive-approximation ADC with up to 26 analog input channels. It includes an internal 1.45 V reference voltage and an on-die temperature sensor - both accessible without external components. This ADC operates across the full 1.6–5.5 V supply range, and its conversion results are directly usable by the R5F100PLAFA#30's DMA and interrupt system.

What low-power modes are available on the R5F100PLAFA#30, and what is the lowest achievable current draw?

The R5F100PLAFA#30 supports HALT, STOP, and SNOOZE modes. In STOP mode with only RTC and LVD active, it draws just 0.57 μA - verified at VDD = 1.8–5.5 V and TA = –40 to +85°C. SNOOZE mode enables serial interface wake-up while keeping CPU halted, achieving sub-10 μA average current in typical polling scenarios - a key advantage of the R5F100PLAFA#30 for battery-operated designs.

Is the R5F100PLAFA#30 pin-compatible with other RL78/G13 family members, and what package does it use?

The R5F100PLAFA#30 uses a 100-pin plastic LQFP package (14 × 20 mm, 0.65-mm pitch) per PLQP0100JC-A standard. It is pin-compatible with other RL78/G13 100-pin variants sharing the same LQFP-0.65mm footprint - including R5F100PKAFA#30 and R5F100PJAFA#30 - enabling memory-scaling upgrades without PCB revision, provided the R5F100PLAFA#30's 512 KB flash requirement is met.
