Renesas R5F101PLDFA#10

Overview

R5F101PLDFA#10 from Renesas is a 100-pin LQFP-0.65mm, industrial-grade RL78/G13 16-bit microcontroller with 64 KB flash, 4 KB data flash, and 2 KB RAM, operating from 1.6 V to 5.5 V at -40°C to +85°C. It delivers 41 DMIPS at 32 MHz, features ultra-low power consumption (66 μA/MHz active, 0.57 μA RTC+LVD), and integrates 16-bit timers, 10-bit ADC (16 channels), UART/I²C/CSI interfaces, and real-time clock - used in smart metering, industrial HMI, and battery-powered sensor nodes.

For engineers reviewing the R5F101PLDFA#10 datasheet, R5F101PLDFA#10 pinout, R5F101PLDFA#10 application, or R5F101PLDFA#10 equivalent, key selection criteria include its 100-pin LQFP package, absence of on-chip data flash (R5F101x series), industrial temperature rating, and support for background data flash rewriting via BGO mode.

Technical Context

The R5F101PLDFA#10 implements the RL78 CPU core with 3-stage pipeline CISC architecture, supporting instruction execution times from 0.03125 μs (32 MHz high-speed mode) to 30.5 μs (32.768 kHz subsystem clock). It includes dedicated low-power modes (HALT, STOP, SNOOZE), on-chip POR/LVD, and DMA controller with 4 channels.

Its peripheral set includes up to 16-channel 10-bit A/D converter with internal 1.45 V reference and temperature sensor, 3–10 I²C/Simplified I²C channels, 2–4 UART/LIN channels, and 8–16 16-bit timer channels - all configurable for deterministic real-time control in resource-constrained embedded systems.

FAQ

What is the maximum operating frequency and corresponding DMIPS rating for R5F101PLDFA#10?

The R5F101PLDFA#10 operates at up to 32 MHz with an RL78 CPU core delivering 41 DMIPS. This performance level is achieved using the high-speed on-chip oscillator calibrated to ±1.0% accuracy across 1.8–5.5 V and –20°C to +85°C ambient conditions. The R5F101PLDFA#10 maintains this rating without external crystal dependency for many timing-critical applications.

Does R5F101PLDFA#10 include on-chip data flash memory?

No, the R5F101PLDFA#10 does not include on-chip data flash memory. As indicated by the "101" prefix in the part number per Renesas documentation, this variant provides 64 KB of code flash only, with no dedicated data flash. For applications requiring nonvolatile parameter storage, R5F100PLDFA#10 (64 KB code flash + 4 KB data flash) is the functional counterpart.

What are the supported low-power modes and their typical current consumption for R5F101PLDFA#10?

The R5F101PLDFA#10 supports HALT, STOP, and SNOOZE modes. In STOP mode with only RTC and LVD active, it draws 0.57 μA typical. HALT mode consumes 66 μA/MHz during active operation. These values are measured at VDD = 3.0 V and TA = 25°C, and are validated across the full industrial temperature range (–40°C to +85°C).

Which communication interfaces are integrated into R5F101PLDFA#10?

The R5F101PLDFA#10 integrates UART (up to 4 channels, LIN-capable), I²C/Simplified I²C (up to 10 channels), and CSI (Simplified SPI, up to 8 channels). All interfaces support multi-master operation and share flexible pin mapping - for example, P11 serves as RxD0, SDA00, or SI00 depending on peripheral configuration in the system clock control register.

What is the analog input capability of R5F101PLDFA#10, including resolution and channel count?

The R5F101PLDFA#10 features a 10-bit successive-approximation ADC with 16 analog input channels (ANI0–ANI15), internal 1.45 V reference voltage, and integrated temperature sensor. It supports single- or continuous-conversion modes, scan sequencing, and hardware-triggered sampling - all configurable via the ADCSR and ADM0 registers without CPU intervention.
