Product details
Overview
R7F100GJH2DFA#BA0 from Renesas is a 52-pin LFQFP, 0.65-mm pitch, consumer-grade (D) 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 at -40 to +85°C. It integrates capacitive touch sensing (CTSU2L), 16-bit TAU timers (12 channels), UARTA (4 channels), IICA (6 channels), and a 12-bit ADC (20 channels), targeting low-power HMI and sensor interface applications in home appliances.
For engineers reviewing the R7F100GJH2DFA#BA0 datasheet, R7F100GJH2DFA#BA0 pinout, R7F100GJH2DFA#BA0 application, or R7F100GJH2DFA#BA0 equivalent, key selection criteria include its 256 KB flash/24 KB RAM configuration, 52-pin LFQFP package with exposed thermal pad, integrated CTSU2L for up to 64-key mutual-capacitance touch, and support for SNOOZE mode sequencer for ultra-low-power background sensing without CPU wake-up.
Technical Context
The R7F100GJH2DFA#BA0 implements the RL78 CPU core with 3-stage pipeline, supporting instruction execution times from 0.03125 µs (32 MHz high-speed mode) to 30.5 µs (32.768 kHz ultra-low-speed mode). Its power architecture includes HALT, STOP, and SNOOZE modes - with 210-nA data retention current and 41-µA/MHz active current enabling battery-operated designs.
Peripheral integration includes a 21-command SNOOZE mode sequencer (SMS) for autonomous sensor polling, Logic & Event Link Controller (ELCL) for hardware-triggered peripheral chaining, and dual-voltage I/O (1.8/2.5/3.0 V compatible) with N-ch open-drain pins. The CTSU2L unit supports both self- and mutual-capacitance methods, configurable via register settings without firmware overhead.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Core | RL78 16-bit CISC with 3-stage pipeline; enables deterministic real-time control with low gate count and minimal power. |
| Flash / RAM | 256 KB code flash + 8 KB data flash + 24 KB RAM; sufficient for complex HMI stacks with background logging and OTA update staging. |

Pinout & Package
Package: 52-pin LFQFP (10 × 10 mm, 0.65-mm pitch) with exposed thermal pad (PLQP0052JA-A). Pin 1 marked by index notch; REGC requires 0.47–1 µF capacitor to VSS.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| P00 | ANI17 / TI00 / TxD1 | Analog input channel 17, timer input 00, UARTA channel 1 transmit; enables combined sensor timing and serial telemetry. |

| VDD / VSS | Power supply / Ground | Dual VDD/VSS pairs (pins 11/12 and 49/50) reduce noise coupling; exposed thermal pad must be connected to PCB ground plane. |
Key Features
| Feature | Design Value |
|---|---|
| SNOOZE Mode Sequencer (SMS) | Executes up to 32 sequential commands (e.g., ADC sampling → compare → CTSU2L scan → RAM store) autonomously, eliminating CPU wake-up and reducing average current to ~2.1 µA. |
| Capacitive Touch Unit (CTSU2L) | Supports mutual-capacitance 8×8 matrix (64 keys) with built-in noise rejection and auto-calibration; no external components required for robust touch panel interfaces. |
| Logic & Event Link Controller (ELCL) | Hardware-configurable logic gates and flip-flops route signals between peripherals (e.g., timer overflow → ADC trigger → DMA transfer), offloading CPU and reducing ISR latency. |
| Data Flash Background Operation | Enables 1,000,000 write cycles with BGO: CPU executes from code flash while rewriting data flash, critical for field-upgradable firmware and parameter storage. |
| Dual-Voltage I/O Ports | Configurable for 1.8 V, 2.5 V, or 3.0 V logic levels; permits direct interfacing with mixed-voltage peripherals (e.g., 1.8 V sensors, 3.3 V displays) without level shifters. |

FAQ
What is the maximum operating frequency and corresponding instruction cycle time for the R7F100GJH2DFA#BA0?
The R7F100GJH2DFA#BA0 supports up to 32 MHz operation using the high-speed on-chip oscillator, delivering a minimum instruction execution time of 0.03125 µs. This timing is confirmed in the RL78/G23 datasheet Rev.1.40 Section 1.1, and applies across the full 1.6–5.5 V supply range with ±1.0% oscillator accuracy.
Does the R7F100GJH2DFA#BA0 support hardware-accelerated cryptographic functions?
No, the R7F100GJH2DFA#BA0 does not include dedicated cryptographic accelerators (e.g., AES, SHA, RSA). It relies on software libraries for encryption; security features are limited to flash memory block erase/write prohibition and boot swapping for firmware integrity.
How many capacitive touch channels does the CTSU2L unit support on the R7F100GJH2DFA#BA0?
The CTSU2L unit on the R7F100GJH2DFA#BA0 supports up to 32 self-capacitance channels or 64 mutual-capacitance channels (8×8 matrix). This capability is explicitly documented in Section 1.1 of the R01DS0395EJ0140 datasheet and applies to all RL78/G23 variants including R7F100GJH2DFA#BA0.
Is the R7F100GJH2DFA#BA0 pin-compatible with other RL78/G23 52-pin variants like R7F100GJL2DFA#BA0?
Yes, the R7F100GJH2DFA#BA0 shares identical pinout and package (52-pin LFQFP, PLQP0052JA-A) with all other 52-pin RL78/G23 variants, including R7F100GJL2DFA#BA0. Differences are limited to flash/RAM size and temperature grade - no PCB redesign is needed when upgrading within the same pin count.
What debug interface does the R7F100GJH2DFA#BA0 use, and which pins are required?
The R7F100GJH2DFA#BA0 uses the Renesas FINE debug interface, requiring P40 (TOOL0) and RESET pins. No dedicated SWD/JTAG pins are present; debugging is performed via the single-wire FINE protocol, as specified in Section 1.3.4 of the R01DS0395EJ0140 datasheet for 52-pin configurations.
