Product details
Overview
R7F100GSJ3CFB#BA0 from Renesas is a 128-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 (41 µA/MHz active, 210 nA data retention), integrates capacitive touch sensing (up to 64 keys), RTC, 16-bit timers, 12-bit ADC (26 channels), and dual DACs-targeting battery-powered HMI and sensor edge nodes.
For engineers reviewing the R7F100GSJ3CFB#BA0 datasheet, R7F100GSJ3CFB#BA0 pinout, R7F100GSJ3CFB#BA0 application, or R7F100GSJ3CFB#BA0 equivalent, key selection considerations include its LFQFP-128 (0.5 mm pitch) package, -40°C to +105°C industrial temperature rating, SNOOZE mode sequencer for autonomous low-power sensing, and hardware ELCL for event-driven peripheral coordination without CPU wake-up.
Technical Context
The R7F100GSJ3CFB#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 executes up to 32 preconfigured commands-including comparisons and calculations-using dedicated hardware, enabling periodic sensor sampling and threshold detection while keeping CPU, flash, and RAM powered down.
Peripheral integration includes Logic and Event Link Controller (ELCL) for configurable signal routing between peripherals (e.g., timer output triggering ADC conversion), background data flash rewriting (BGO), and capacitive sensing unit (CTSU2L) supporting both self- and mutual-capacitance modes with built-in noise suppression and auto-tuning.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit MCU applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R7F100GLJ3CFB#BA0 | 64-pin LFQFP, 256 KB flash, 24 KB RAM, same core/peripherals but fewer I/O (64 vs. 128 pins) and no mutual-capacitance CTSU support. | Suitable for space-constrained designs with ≤48 GPIO and only self-capacitance touch requirements (≤32 keys). | Select when PCB area is critical and full 128-pin I/O or 64-key touch matrix is unnecessary. |
| R7F100GSN3CFB#BA0 | Same 128-pin LFQFP package and CTSU capability, but 768 KB flash and 48 KB RAM-higher memory density with identical peripheral set and power profile. | Required for complex firmware with large protocol stacks (e.g., Modbus TCP + OTA), where R7F100GSJ3CFB#BA0's 256 KB flash is insufficient. | Choose when future firmware expansion headroom or dual-bank secure boot is needed, accepting higher cost and flash write endurance trade-offs. |
Compared with R7F100GLJ3CFB#BA0, the R7F100GSJ3CFB#BA0 provides double the GPIO count and full mutual-capacitance touch support essential for advanced HMIs; versus R7F100GSN3CFB#BA0, it offers optimal cost-performance balance for mid-tier industrial controllers where 256 KB flash suffices and memory overhead is minimized.

FAQ
What is the maximum operating frequency and corresponding supply voltage range for the R7F100GSJ3CFB#BA0?
The R7F100GSJ3CFB#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, 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 timing, maintaining full functionality down to 1.6 V.
Does the R7F100GSJ3CFB#BA0 support hardware-accelerated cryptographic functions?
No, the R7F100GSJ3CFB#BA0 does not include dedicated cryptographic accelerators (e.g., AES, SHA). It relies on software libraries for encryption; however, its multiply/divide/accumulate instructions and 24 KB RAM support efficient implementation of lightweight protocols like AES-128 or ECC for secure boot and OTA updates.
How many capacitive touch channels does the R7F100GSJ3CFB#BA0 support in mutual-capacitance mode?
The R7F100GSJ3CFB#BA0 supports up to 64 keys in mutual-capacitance mode using an 8 × 8 pin matrix configuration via its CTSU2L unit. This requires 16 dedicated pins (8 X-lines + 8 Y-lines) and enables robust multi-touch detection with built-in noise cancellation and auto-tuning-fully supported in the R7F100GSJ3CFB#BA0's 128-pin LFQFP package.
What debug interface options are available for the R7F100GSJ3CFB#BA0?
The R7F100GSJ3CFB#BA0 supports on-chip debugging via the dedicated TOOL0 pin (SWD-compatible serial wire debug) and optional use of P10/P11 pins for UART-based debug output. It does not support JTAG; Renesas-provided E2 studio and CS+ IDE fully support flash programming, breakpoint setting, and real-time variable monitoring through the SWD interface.
Can the R7F100GSJ3CFB#BA0 operate reliably at 105°C ambient temperature with full peripheral functionality?
Yes, the R7F100GSJ3CFB#BA0 is rated for industrial temperature operation from -40°C to +105°C (suffix "C" in part number denotes industrial grade). All specifications-including 256 KB flash read/write, 24 KB RAM retention, CTSU2L touch sensitivity, and 16-bit ADC accuracy-are guaranteed across this full range per Renesas datasheet R01DS0395EJ0140.
