Overview

R5F104PLAFA#30 from Renesas is a 100-pin LQFP-0.65 mm pitch, industrial-grade (TA = −40 to +85°C) RL78/G14 16-bit MCU with 384 KB flash, 8 KB data flash, 32 KB RAM, 48-channel I/O, and integrated peripherals including 12-bit RTC, 10-bit ADC (19 channels), UART/LIN ×4, CSI ×6, I²C ×4, 16-bit timers ×10, and ultra-low-power operation (66 μA/MHz active, 0.60 μA in RTC+LVD mode). It targets embedded control in HVAC, motor drives, and smart appliances.

For engineers reviewing the R5F104PLAFA#30 datasheet, R5F104PLAFA#30 pinout, R5F104PLAFA#30 application, or R5F104PLAFA#30 equivalent, key selection criteria include its 384 KB code flash capacity, 100-pin LQFP package with 0.65 mm pitch, −40 to +85°C industrial temperature rating, and support for background data flash rewriting (BGO) and event-link controller (ELC) for deterministic peripheral triggering.

Technical Context

The R5F104PLAFA#30 implements the RL78 CPU core with CISC architecture, 3-stage pipeline, and configurable instruction timing (0.03125 µs min @ 32 MHz to 30.5 µs @ 32.768 kHz). It integrates a Data Transfer Controller (DTC) supporting normal, repeat, and block transfer modes triggered by 19–26 event sources via the Event Link Controller (ELC).

Its power architecture includes HALT, STOP, and SNOOZE low-power modes, on-chip POR and 14-level LVD, and a high-accuracy ±1.0% on-chip oscillator (1–64 MHz). The peripheral set includes dual 10-bit ADC units with internal reference (1.45 V) and temperature sensor, plus two 8-bit DAC channels with real-time output capability.

FAQ

What is the maximum operating frequency and instruction throughput of the R5F104PLAFA#30?

The R5F104PLAFA#30 operates at up to 32 MHz with a peak performance of 44 DMIPS. Its RL78 CPU core achieves a minimum instruction execution time of 0.03125 µs at 32 MHz using the high-speed on-chip oscillator. The CISC architecture with 3-stage pipeline and hardware multiply/divide ensures deterministic timing for real-time control loops. This performance level is confirmed in the R01DS0053EJ0370 datasheet Section 1.1.

Does the R5F104PLAFA#30 support in-system programming and secure firmware updates?

Yes, the R5F104PLAFA#30 supports full in-system programming via on-chip debug interface and includes flash shield window, block erase prohibition, and boot swapping for secure firmware updates. Self-programming is enabled with dedicated RAM usage (start address F3F00H) and operates across the full VDD range (1.8–5.5 V). These features are documented in Section 1.1 "Code Flash Memory" of the R01DS0053EJ0370 datasheet.

How many analog-to-digital converter (ADC) channels does the R5F104PLAFA#30 provide, and what resolution and reference options are available?

The R5F104PLAFA#30 integrates a 10-bit successive-approximation ADC with 19 analog input channels (ANI0–ANI19), internal 1.45 V reference voltage, and temperature sensor. It supports single- or continuous-conversion modes and operates across the full 1.6–5.5 V supply range. Channel selection and timing are fully configurable via dedicated registers, as specified in Section 1.1 "A/D Converter" of the R01DS0053EJ0370 datasheet.

What low-power modes are available on the R5F104PLAFA#30, and what is the typical current consumption in each?

The R5F104PLAFA#30 offers HALT (66 μA/MHz), STOP (0.60 μA with RTC + LVD active), and SNOOZE modes. In STOP mode, only the RTC and LVD remain operational-enabling calendar timekeeping and brown-out detection while minimizing power. All modes retain RAM content and support fast wake-up via interrupts. These values are measured at VDD = 3.0 V, TA = 25°C, and published in Section 1.1 "Ultra-Low Power Consumption Technology" of R01DS0053EJ0370.

Is the R5F104PLAFA#30 pin-compatible with other RL78/G14 variants such as R5F104MLAFA#30 or R5F104PKAFA#30?

No, the R5F104PLAFA#30 is not pin-compatible with R5F104MLAFA#30 (80-pin LQFP) or R5F104PKAFA#30 (100-pin LFQFP). While all share the RL78/G14 core and peripheral IP, they differ in package type (LQFP-0.65 mm vs. LQFP-0.65 mm vs. LFQFP-0.5 mm), pin count (100 vs. 80 vs. 100), and pin assignment. The R5F104PLAFA#30 uses PLQP0100JC-A code and requires its specific 100-pin LQFP-0.65 mm footprint.
