Product details
Overview
R7F100GLN3CFA#BA0 from Renesas is a 64-pin LQFP-packaged RL78/G23 16-bit microcontroller with 512 KB code flash, 8 KB data flash, and 48 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 (up to 64 keys), and dual-clock domain operation for industrial control applications requiring long battery life and robust HMI.
For engineers reviewing the R7F100GLN3CFA#BA0 datasheet, R7F100GLN3CFA#BA0 pinout, R7F100GLN3CFA#BA0 application, or R7F100GLN3CFA#BA0 equivalent, this page provides verified technical context, package-validated pin functions, real-world use cases in industrial HMIs and sensor nodes, and two confirmed alternative parts with documented functional trade-offs.
Technical Context
The R7F100GLN3CFA#BA0 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). Its SNOOZE mode sequencer enables autonomous low-power peripheral sequencing without CPU wake-up, using 32 programmable commands across 21 operations.
It integrates a Logic and Event Link Controller (ELCL) for hardware-level event routing between peripherals, a Data Transfer Controller (DTC) with chain transfer capability, and a capacitive sensing unit (CTSU2L) supporting both self- and mutual-capacitance configurations-enabling up to 64-key matrix touch interfaces without external components.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Core Architecture | RL78 16-bit CISC with 3-stage pipeline; enables deterministic real-time response and compact code size. |
| Flash Memory | 512 KB code flash + 8 KB data flash; supports background operation (BGO) and 1M rewrite cycles for firmware updates and logging. |
| RAM | 48 KB on-chip RAM; retains data at 210 nA in STOP mode, enabling fast wake-up with full context preservation. |

FAQ
What is the maximum operating temperature specification for the R7F100GLN3CFA#BA0?
The R7F100GLN3CFA#BA0 is rated for industrial applications with an operating ambient temperature range of -40°C to +105°C (denoted by the '3' in the part number suffix). This rating applies to the full functional specification including 512 KB flash operation, CTSU2L touch sensing, and real-time clock accuracy-verified across the entire temperature range per Renesas datasheet R01DS0395EJ0140.
Does the R7F100GLN3CFA#BA0 support hardware-based capacitive touch sensing without external components?
Yes, the R7F100GLN3CFA#BA0 integrates the CTSU2L capacitive sensing unit capable of self-capacitance (up to 32 keys) and mutual-capacitance (8×8 matrix = 64 keys) operation. It requires only external sense electrodes and a single 100 nF decoupling capacitor per channel-no external touch controller, op-amps, or RC networks are needed for basic implementation.
How many UART channels does the R7F100GLN3CFA#BA0 support, and do they include LIN bus functionality?
The R7F100GLN3CFA#BA0 supports six UART channels (UARTA), all of which include LIN bus protocol support per ISO 17987-4. Each channel can operate in standard UART mode or LIN master/slave mode with automatic sync-break detection, checksum calculation, and identifier filtering-enabling direct connection to automotive or industrial LIN networks without external transceivers.
What debug interface options are available on the R7F100GLN3CFA#BA0?
The R7F100GLN3CFA#BA0 supports on-chip debugging via the dedicated TOOL0 (pin P40) and TOOLRxD/TOOLTxD (pins P11/P12) signals, compatible with Renesas E2 emulator and E2 Lite. It does not require SWD or JTAG pins-debugging uses the same UART physical layer, minimizing pin count impact while supporting full breakpoint, watchpoint, and memory inspection capabilities.
Can the R7F100GLN3CFA#BA0 execute code while rewriting data flash memory?
Yes, the R7F100GLN3CFA#BA0 supports Background Operation (BGO) for data flash memory. While rewriting 8 KB of data flash, the CPU can simultaneously execute instructions from code flash-including real-time control loops and interrupt service routines-ensuring uninterrupted system operation during firmware updates or parameter logging.
