Product details
Overview
R7F100GPL3CFB#BA0 from Renesas is a 100-pin LFQFP, 0.50-mm pitch, industrial-grade (−40 to +105°C) RL78/G23 16-bit MCU with 512 KB code flash, 8 KB data flash, and 48 KB RAM. It delivers true low-power operation (41 µA/MHz active, 210 nA data retention), integrated capacitive touch sensing (CTSU2L), and dual-clock domain support for real-time control in battery-powered industrial HMI and sensor nodes.
For engineers reviewing the R7F100GPL3CFB#BA0 datasheet, R7F100GPL3CFB#BA0 pinout, R7F100GPL3CFB#BA0 application, or R7F100GPL3CFB#BA0 equivalent, key selection criteria include its 100-pin LFQFP package with dedicated CTSU2L pins, 512 KB flash/48 KB RAM memory configuration, SNOOZE mode sequencer for autonomous low-power wake-up, and industrial temperature rating with LVD0/LVD1 voltage detectors.
Technical Context
The R7F100GPL3CFB#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 (SMS) executes up to 32 preconfigured commands-including comparisons and calculations-without CPU, RAM, or flash activation, enabling ultra-low-power periodic sensing.
Peripheral integration includes a Logic and Event Link Controller (ELCL) for configurable event routing between peripherals, a Data Transfer Controller (DTC) with chain transfer capability, and a Realtime Clock (RTC) with alarm interrupt and ±1 ppm correction. The CTSU2L unit supports both self-capacitance (up to 32 keys) and mutual capacitance (8×8 matrix, up to 64 keys) operation at VDD = 1.8–5.5 V.

Applications
| Industrial HMI Panels | Smart Sensor Nodes |
|---|---|
Use Scenario: 100-pin MCU drives multi-zone capacitive touch overlay on factory-floor operator panels with backlight dimming and RS-485 communication.

Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R7F100GLL3CFB#BA0 | 64-pin LFQFP, 512 KB flash, 48 KB RAM, −40 to +105°C; lacks 36 extra GPIOs and 10+ analog channels of R7F100GPL3CFB#BA0 | Targeted for space-constrained industrial controls where 100-pin footprint is prohibitive but full peripheral set is not required | Select when board area is critical and I/O count < 64 suffices; verify CTSU2L channel count meets touch key requirements |
| R7F100GML3CFB#BA0 | 80-pin LFQFP, 512 KB flash, 48 KB RAM, −40 to +105°C; omits 20 GPIOs and 4 CTSU2L channels vs. R7F100GPL3CFB#BA0 | Suitable for mid-tier HMIs with smaller touch surfaces and fewer serial interfaces than full 100-pin implementation demands | Choose for cost-optimized designs needing 512 KB flash and industrial temp but not maximum I/O density |
Compared with R7F100GLL3CFB#BA0 and R7F100GML3CFB#BA0, the R7F100GPL3CFB#BA0 provides 100-pin expandability for complex industrial I/O, full 26-channel ADC support, and maximum CTSU2L channel count-making it the only option among the three capable of driving large-format capacitive touch panels while maintaining dual UART, I²C, and SPI concurrency.

FAQ
What is the operating temperature range for the R7F100GPL3CFB#BA0?
The R7F100GPL3CFB#BA0 is rated for industrial operation from −40°C to +105°C (3C grade), verified per Renesas R01DS0395EJ0140 Rev.1.40. This range applies to all specified electrical characteristics including flash programming, ADC accuracy, and CTSU2L touch sensitivity-no derating required within this envelope.
Does the R7F100GPL3CFB#BA0 support background data flash rewriting while executing code?
Yes, the R7F100GPL3CFB#BA0 supports Background Operation (BGO) for data flash. Instructions can execute from code flash memory while data flash is being rewritten-enabling seamless firmware updates, secure logging, and parameter storage without halting application code. BGO is enabled via the FENTRY register and managed by the flash control circuitry.
How many capacitive touch channels does the R7F100GPL3CFB#BA0 support in mutual capacitance mode?
The R7F100GPL3CFB#BA0 supports up to 64 keys in mutual capacitance mode using an 8 × 8 pin matrix configuration via its CTSU2L unit. This requires dedicated CTSU2L pins (e.g., P30–P31, P60–P62, and others mapped in Table 1-1), and operates across the full 1.8–5.5 V VDD range without external components.
What clock sources are available for the RTC in the R7F100GPL3CFB#BA0?
The R7F100GPL3CFB#BA0 RTC uses the 32.768 kHz subsystem clock, which can be driven by either the internal low-speed on-chip oscillator (typ. 32.768 kHz) or an external 32.768 kHz crystal connected to P121 (XT1). Crystal operation provides higher accuracy (±20 ppm) versus internal oscillator (±5,000 ppm), and both support RTC alarm and correction features.
Can the R7F100GPL3CFB#BA0 generate PWM signals with dead-time insertion for motor control?
The R7F100GPL3CFB#BA0 does not include hardware dead-time insertion. However, its Timer Array Unit (TAU) supports complementary PWM output via paired channels (e.g., TO00/TO01), and dead time can be implemented in firmware using interrupt-driven edge delays or by leveraging the SNOOZE mode sequencer for precise timing-critical waveform shaping without CPU load.
