Product details
Overview
R7F100GPN3CFB#HA0 from Renesas is a 100-pin LFQFP, industrial-grade RL78/G23 16-bit microcontroller with 256 KB code flash, 8 KB data flash, 24 KB RAM, 1.6–5.5 V operation, and integrated capacitive touch sensing unit (CTSU2L). It delivers ultra-low power consumption (41 µA/MHz active, 210 nA data retention), supports SNOOZE mode for autonomous peripheral sequencing, and targets battery-powered HMI, sensor nodes, and industrial control.
For engineers reviewing the R7F100GPN3CFB#HA0 datasheet, R7F100GPN3CFB#HA0 pinout, R7F100GPN3CFB#HA0 application, or R7F100GPN3CFB#HA0 equivalent, key selection criteria include its 100-pin LFQFP-0.5 mm package, -40 to +105°C temperature grade, 256 KB flash/24 KB RAM memory configuration, CTSU2L capacitive sensing support, and SNOOZE mode sequencer for low-power event-driven operation without CPU wake-up.
Technical Context
The R7F100GPN3CFB#HA0 implements the RL78 CPU core with 3-stage pipeline CISC architecture, supporting instruction execution times from 0.03125 µs (32 MHz high-speed mode) to 30.5 µs (32.768 kHz ultra-low-speed mode). It integrates a dedicated SNOOZE mode sequencer (SMS) capable of executing up to 32 sequential commands across 21 supported instructions-enabling autonomous analog measurement, comparison, and conditional branching while keeping CPU, flash, and RAM powered down.
Peripheral integration includes a Logic and Event Link Controller (ELCL) for configurable signal routing between peripherals, a Data Transfer Controller (DTC) with chain transfer capability, and dual-clock domain operation: high-speed on-chip oscillator (±1.0% accuracy, 1–32 MHz selectable) and independent 32.768 kHz low-speed oscillator for RTC and watchdog timing. The device supports background data flash rewriting (BGO) and secure flash protection via block erase prohibition.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R7F100GPK3CFB#HA0 | Same 100-pin LFQFP package, but 384 KB flash / 32 KB RAM; higher memory headroom for larger protocol stacks | Better suited for applications requiring embedded web server, advanced encryption, or multi-protocol coexistence (e.g., Modbus + BACnet) | Select when firmware size exceeds 200 KB or RAM usage consistently exceeds 18 KB in profiling |
| R7F100GPL3CFB#HA0 | Same 100-pin LFQFP package, but 192 KB flash / 20 KB RAM; lower cost, reduced memory footprint | Ideal for cost-sensitive, functionally fixed designs like simple thermostats or fan speed controllers | Select when application fits within 150 KB flash and uses <15 KB RAM-reduces BoM cost by ~12% at volume |
Compared with R7F100GPK3CFB#HA0 and R7F100GPL3CFB#HA0, the R7F100GPN3CFB#HA0 offers optimal balance: sufficient memory for dual-role firmware (control + comms), verified CTSU2L performance at 100-pin scale, and industrial temperature margin without over-provisioning silicon area or cost.

FAQ
What is the maximum operating frequency and corresponding instruction cycle time for the R7F100GPN3CFB#HA0?
The R7F100GPN3CFB#HA0 supports a maximum high-speed on-chip oscillator frequency of 32 MHz, delivering a minimum instruction execution time of 0.03125 µs. This timing is achieved using the high-speed on-chip oscillator clock source; the device also supports ultra-low-speed operation at 32.768 kHz with a 30.5 µs instruction cycle for RTC and deep-sleep functions. All timing specifications are validated across the full -40 to +105°C industrial temperature range.
Does the R7F100GPN3CFB#HA0 support hardware-accelerated cryptographic operations?
No, the R7F100GPN3CFB#HA0 does not include dedicated cryptographic acceleration hardware such as AES engines or TRNG modules. Security relies on software libraries for basic encryption (e.g., AES-128 in ECB/CBC mode) and secure boot via flash shield window and block erase prohibition. For applications requiring certified cryptographic acceleration, Renesas recommends the RA family or RL78/I1A with integrated crypto IP.
How many capacitive touch channels can be implemented using the CTSU2L unit on the R7F100GPN3CFB#HA0?
The CTSU2L unit on the R7F100GPN3CFB#HA0 supports up to 32 self-capacitance channels (one per dedicated CTSU pin) or up to 64 mutual-capacitance channels in an 8×8 matrix configuration. Pin assignment is flexible-any GPIO with CTSU functionality (e.g., P20–P25, P30–P31, P70–P73) can be configured as CTSU electrodes. Full channel count assumes use of all 32 CTSU-capable pins in mutual mode with appropriate PCB layout.
What debug interfaces are available on the R7F100GPN3CFB#HA0, and are they accessible in the 100-pin LFQFP package?
The R7F100GPN3CFB#HA0 supports on-chip debugging via the dedicated TOOL0 (pin 40) and TOOLRxD/TOOLTxD (pins 25/24) signals, compatible with Renesas E2 emulator and E2 Lite. These debug pins are fully routed and functional in the 100-pin LFQFP package. No JTAG or SWD interface is provided-the debug protocol is proprietary Renesas FINE, requiring Renesas debug tools and CS+ or e2 studio IDE.
Can the R7F100GPN3CFB#HA0 operate reliably from a single 1.8 V supply, and what peripherals remain functional at that voltage?
Yes, the R7F100GPN3CFB#HA0 operates reliably from 1.8 V (within its 1.6–5.5 V specification). At 1.8 V, the high-speed on-chip oscillator is limited to ≤8 MHz, and the ADC operates with 10-bit resolution (not 12-bit). All digital peripherals-including UART, I²C, timers, CTSU2L, and DMA-remain fully functional. The internal voltage reference (1.48 V) and temperature sensor retain specified accuracy, enabling valid sensor readings and voltage monitoring at low VDD.
