Product details
Overview
R7F100GPL3CFA#BA0 from Renesas is a 100-pin, industrial-grade RL78/G23 16-bit MCU with 512 KB code flash, 48 KB RAM, and 8 KB data flash, 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 battery-powered HMI and sensor-edge applications.
For engineers reviewing the R7F100GPL3CFA#BA0 datasheet, R7F100GPL3CFA#BA0 pinout, R7F100GPL3CFA#BA0 application, or R7F100GPL3CFA#BA0 equivalent, key selection criteria include its 100-pin LFQFP package, -40°C to +105°C industrial temperature rating, integrated RTC and SNOOZE mode sequencer for autonomous low-power sensing, and support for LIN-bus UARTA and I²C interfaces in resource-constrained embedded designs.
Technical Context
The R7F100GPL3CFA#BA0 implements the RL78 CPU core with CISC architecture and 3-stage pipeline, enabling configurable instruction execution times from 0.03125 µs (32 MHz) to 30.5 µs (32.768 kHz). Its SNOOZE mode sequencer executes up to 32 preconfigured operations-including ADC sampling, comparator comparison, and timer-triggered wakeups-without CPU, RAM, or flash activation.
Peripheral integration includes a 12-bit A/D converter (26 channels), dual 8-bit D/A outputs, two comparators with selectable internal/external reference, and an ELCL that routes event signals between peripherals (e.g., ADC completion → DMA trigger → UART transmit). The device supports background data flash rewriting (BGO) and secure self-programming with boot swapping.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Core Architecture | RL78 16-bit CISC with 3-stage pipeline and multiply/divide instructions |
| Operating Voltage | 1.6–5.5 V - enables direct interface with 1.8 V, 2.5 V, 3.3 V, and 5 V peripherals without level shifters |
| Flash Memory | 512 KB code flash + 8 KB data flash - supports firmware updates and nonvolatile parameter storage with 1M rewrite cycles (data flash) |
| RAM | 48 KB on-chip RAM - sufficient for real-time control stacks, communication buffers, and capacitive touch algorithm execution |
| Power Modes | HALT, STOP, SNOOZE - STOP mode achieves 210 nA retention current; SNOOZE enables autonomous peripheral sequencing without CPU wake-up |

FAQ
What is the maximum operating frequency and corresponding supply voltage range for the R7F100GPL3CFA#BA0?
The R7F100GPL3CFA#BA0 operates up to 32 MHz using its high-speed on-chip oscillator, with guaranteed functionality across its full 1.6–5.5 V supply range. At 32 MHz, the minimum instruction execution time is 0.03125 µs. The device also supports ultra-low-speed operation at 32.768 kHz for RTC and deep-sleep functions, maintaining full functionality down to 1.6 V.
Does the R7F100GPL3CFA#BA0 support LIN bus communication, and which peripheral implements it?
Yes, the R7F100GPL3CFA#BA0 supports LIN bus communication via its UARTA peripheral. UARTA channels include LIN-specific features such as automatic sync byte detection, checksum generation/validation, and break field timing control - all implemented in hardware without CPU intervention. Up to six UARTA channels are available, with pin mapping confirmed for P00/P01 (TxD1/RxD1) and other designated pins in the 100-pin LFQFP package.
How many capacitive touch channels does the R7F100GPL3CFA#BA0 support, and what configuration options are available?
The R7F100GPL3CFA#BA0 supports up to 64 capacitive touch keys using its CTSU2L unit in mutual-capacitance mode (8 × 8 matrix), or up to 32 keys in self-capacitance mode. Configuration is software-selectable, and the unit operates independently of the CPU in SNOOZE mode. All 76 GPIO pins are eligible for CTSU use, with dedicated TSCAP and VCOUT0/VCOUT1 pins enhancing noise immunity and sensitivity in both configurations.
What debug and programming interfaces are supported by the R7F100GPL3CFA#BA0?
The R7F100GPL3CFA#BA0 supports on-chip debugging via the dedicated TOOL0 (pin 1), TOOLRxD (P11), and TOOLTxD (P12) pins, compatible with Renesas E2 studio and CS+ IDEs. It includes full SWD/JTAG support through the built-in debug interface, enabling breakpoints, watchpoints, and real-time memory inspection. Flash programming is performed via on-chip bootloader using UARTA or dedicated debug port, with security features including flash shield window and block erase prohibition.
Is the R7F100GPL3CFA#BA0 pin-compatible with other RL78/G23 variants, and what are the key package constraints?
No, the R7F100GPL3CFA#BA0 is not pin-compatible with other RL78/G23 variants due to its unique 100-pin LFQFP (0.50-mm pitch) footprint. While electrical functionality aligns across the family, pin assignments differ significantly between 64-pin LQFP, 80-pin LQFP, and 100-pin LFQFP packages. The R7F100GPL3CFA#BA0 requires PLQP0100KB-B land pattern and adheres to JEDEC MS-026 standards - PCB layout must accommodate its 14 × 14 mm body and thermal pad grounding requirement.
