Renesas R5F100PHDFB#X0

Overview

R5F100PHDFB#X0 from Renesas is a 100-pin LFQFP (0.5-mm pitch), industrial-grade RL78/G13 16-bit MCU with 128 KB flash, 12 KB RAM, and 8 KB data flash, operating from 1.6 V to 5.5 V across –40°C to +105°C. It delivers 41 DMIPS at 32 MHz, integrates a real-time clock, 16-bit timers (12 channels), 10-bit ADC (26 channels), UART/LIN, I²C, CSI, and ultra-low-power modes including STOP (0.57 μA) and HALT.

For engineers reviewing the R5F100PHDFB#X0 datasheet, R5F100PHDFB#X0 pinout, R5F100PHDFB#X0 application, or R5F100PHDFB#X0 equivalent, key selection criteria include its 100-pin LFQFP-0.5 mm industrial temperature rating, integrated data flash with background operation, RTC calendar support, and low-voltage operation down to 1.6 V for battery-powered sensing and control systems.

Technical Context

The R5F100PHDFB#X0 implements the RL78 CPU core with a 3-stage CISC pipeline, supporting instruction execution times from 0.03125 μs (32 MHz high-speed mode) to 30.5 μs (32.768 kHz subsystem clock). Its memory subsystem includes 128 KB code flash (1 KB block size), 8 KB data flash with 1M rewrite cycles and background operation, and 12 KB on-chip RAM.

Peripherals are tightly coupled to low-power operation: the 10-bit ADC supports up to 26 analog inputs with internal 1.45 V reference and temperature sensor; serial interfaces include up to 4 UART/LIN channels, 10 I²C/Simplified I²C channels, and 8 CSI channels; and the RTC provides calendar, alarm, and clock correction functions independent of main system clock.

FAQ

What is the maximum operating frequency and corresponding performance of the R5F100PHDFB#X0?

The R5F100PHDFB#X0 operates at up to 32 MHz using its high-speed on-chip oscillator, delivering 41 DMIPS of processing performance. Its RL78 CPU core achieves this with a 3-stage pipeline and supports configurable instruction timing - from 0.03125 μs per instruction at 32 MHz to 30.5 μs at 32.768 kHz - enabling dynamic trade-offs between speed and power consumption in the R5F100PHDFB#X0.

Does the R5F100PHDFB#X0 support hardware-based encryption or secure boot features?

The R5F100PHDFB#X0 does not integrate hardware AES, SHA, or TRNG modules. It provides flash security features - including flash shield window and prohibition of block erase/rewrite - to protect firmware IP, and supports secure bootloader implementation via software-managed signature verification and boot swap functionality. These capabilities are documented in the R5F100PHDFB#X0 datasheet and applicable application notes.

What are the supported clock sources for the R5F100PHDFB#X0, and can it run from an external crystal?

The R5F100PHDFB#X0 supports multiple clock sources: a high-speed on-chip oscillator (selectable from 1–32 MHz), a low-speed on-chip oscillator (15 kHz), and external clock inputs via XT1/XT2 pins for crystals or oscillators up to 20 MHz. The RTC circuit specifically requires a 32.768 kHz crystal connected to RTCIN/RTCOUT pins. All clock configurations are fully supported in the R5F100PHDFB#X0.

How many UART/LIN channels does the R5F100PHDFB#X0 provide, and are they LIN 2.2 compliant?

The R5F100PHDFB#X0 integrates up to four UART channels, each supporting LIN bus functionality per LIN Specification v2.2. This includes automatic header detection, checksum calculation (classic/enhanced), and slave node response handling. UART0 and UART1 are commonly used for LIN communication in automotive body control modules built around the R5F100PHDFB#X0.

Is the R5F100PHDFB#X0 pin-compatible with other RL78/G13 variants in the 100-pin LFQFP package?

Yes - all RL78/G13 devices in the 100-pin LFQFP package (e.g., R5F100PHDFB#X0, R5F100PLDFB#X0, R5F100PHGFB#X0) share identical pinouts and electrical characteristics. This enables direct substitution for memory or temperature grade upgrades without PCB modification, provided firmware is adapted to leverage additional resources such as larger flash in the R5F100PHDFB#X0's higher-density variants.
