Product details
Overview
R7F100GJF3CFA#HA0 from Renesas is a 52-pin, industrial-grade RL78/G23 16-bit MCU with 256 KB code flash, 8 KB data flash, and 24 KB RAM, operating from 1.6–5.5 V. It delivers ultra-low power consumption (41 µA/MHz active, 210 nA data retention), integrated capacitive touch sensing (CTSU2L), and dual-clock domain operation supporting high-speed (32 MHz) and ultra-low-power (32.768 kHz) modes for battery-powered HMI and sensor edge nodes.
For engineers reviewing the R7F100GJF3CFA#HA0 datasheet, R7F100GJF3CFA#HA0 pinout, R7F100GJF3CFA#HA0 application, or R7F100GJF3CFA#HA0 equivalent, key selection criteria include its 52-pin LQFP-0.65mm package, -40°C to +105°C industrial temperature rating, 256 KB flash/24 KB RAM memory configuration, CTSU2L capacitive sensing support, and SNOOZE mode sequencer for autonomous low-power peripheral sequencing without CPU wake-up.
Technical Context
The R7F100GJF3CFA#HA0 implements the RL78 CPU core with 3-stage pipeline CISC architecture, supporting variable instruction execution time (0.03125 µs at 32 MHz, 30.5 µs at 32.768 kHz). It integrates a dedicated SNOOZE mode sequencer (SMS) capable of executing up to 32 sequential commands across 21 supported operations-enabling autonomous analog monitoring, timer triggering, and I/O control while the CPU, flash, and RAM remain powered down.
Its peripheral set includes a 10-channel 12-bit A/D converter with internal reference (1.48 V) and temperature sensor, dual 8-bit D/A outputs, two comparators with selectable internal/external reference, and flexible serial interfaces: up to 6 UARTA channels (LIN-capable), 10 IICA channels, and 8 CSI/SPI channels-all configurable via peripheral I/O redirection register (PIOR) for layout optimization.

FAQ
What is the maximum operating frequency and clock accuracy of the R7F100GJF3CFA#HA0?
The R7F100GJF3CFA#HA0 supports a maximum operating frequency of 32 MHz using its high-speed on-chip oscillator, which maintains ±1.0% accuracy across VDD = 1.8–5.5 V and TA = −20 to +85°C. This enables precise timing for UART communication, PWM generation, and real-time control loops without requiring an external crystal.
Does the R7F100GJF3CFA#HA0 support capacitive touch sensing, and how many keys can it handle?
Yes, the R7F100GJF3CFA#HA0 integrates the CTSU2L capacitive sensing unit supporting both self-capacitance (up to 32 independent keys) and mutual capacitance (8×8 matrix, up to 64 keys). It operates across the full VDD range (1.8–5.5 V) and includes hardware noise cancellation for reliable operation in electrically noisy industrial environments.
What are the memory resources available on the R7F100GJF3CFA#HA0?
The R7F100GJF3CFA#HA0 provides 256 KB of code flash memory (organized in 2 KB blocks), 8 KB of data flash memory rated for 1,000,000 write/erase cycles, and 24 KB of on-chip RAM. The data flash supports background operation (BGO), allowing program execution from code flash while rewriting data flash-essential for field-upgradable firmware and persistent parameter storage.
What package type and pin count does the R7F100GJF3CFA#HA0 use?
The R7F100GJF3CFA#HA0 uses a 52-pin plastic LQFP package with 0.65-mm pitch (Renesas code PLQP0052JA-A), measuring 10 × 10 mm. It is supplied in embossed tape packaging (#HA0) and qualified for industrial temperature operation from −40°C to +105°C.
How does the SNOOZE mode sequencer (SMS) function on the R7F100GJF3CFA#HA0?
The SNOOZE mode sequencer (SMS) on the R7F100GJF3CFA#HA0 executes up to 32 pre-programmed commands-including ADC conversions, comparator comparisons, GPIO toggles, and timer starts-without waking the CPU, flash, or RAM. This reduces system power to sub-µA levels during periodic sensor polling or status monitoring tasks, extending battery life significantly in always-on edge devices.
