Product details
Overview
R7F100GGJ3CFB#BA0 from Renesas is a 48-pin LFQFP, 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 consumption (41 µA/MHz active, 210 nA data retention), integrated capacitive touch sensing (up to 64 keys), and rich mixed-signal peripherals including 12-bit ADC (26 channels), dual 8-bit DACs, RTC, and multiple UART/I²C/SPI interfaces - deployed in battery-powered industrial HMI and sensor node applications.
For engineers reviewing the R7F100GGJ3CFB#BA0 datasheet, R7F100GGJ3CFB#BA0 pinout, R7F100GGJ3CFB#BA0 application, or R7F100GGJ3CFB#BA0 equivalent, key selection considerations include its 48-pin LFQFP-0.5 mm package, -40°C to +105°C temperature rating, SNOOZE mode sequencer for autonomous low-power sensing, and CTSU2L capacitive touch unit supporting self- and mutual-capacitance configurations.
Technical Context
The R7F100GGJ3CFB#BA0 implements the RL78 CPU core with 3-stage pipeline CISC architecture, supporting configurable instruction execution times from 0.03125 µs (32 MHz) to 30.5 µs (32.768 kHz). Its power management includes HALT, STOP, and SNOOZE modes, with wake-up from STOP in under 4 µs and SNOOZE sequencer executing up to 32 autonomous operations without CPU intervention.
Peripheral integration includes a Logic and Event Link Controller (ELCL) enabling hardware-triggered signal routing between functions, Data Transfer Controller (DTC) with chain transfer support, and a Remote Control Signal Receiver with 4-waveform pattern matching - all operating within the same ultra-low-power envelope as the core and memory subsystems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Core Architecture | RL78 16-bit CISC with 3-stage pipeline; enables deterministic real-time control at ultra-low power. |
| Flash Memory | 256 KB code flash + 8 KB data flash; supports background operation (BGO) and 1M rewrite cycles for robust firmware/data updates. |
| RAM | 24 KB on-chip RAM; retains full 4 KB at 210 nA in STOP mode for fast wake-up state preservation. |
| Operating Voltage | 1.6–5.5 V single supply; eliminates need for external voltage regulators in multi-rail systems. |
| Power Consumption | 41 µA/MHz active current; reduces battery drain in portable industrial devices by >30% vs. prior RL78 generations. |

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R7F100GLJ3CFB#BA0 | 512 KB code flash, 48 KB RAM, same 48-pin LFQFP package and peripheral set | Required for larger firmware images or extended data buffering in complex control algorithms | Select when firmware size exceeds 256 KB or additional RAM is needed for real-time analytics buffers |
| R7F100GGJ3CFA#BA0 | Same memory (256 KB/24 KB), but 44-pin LQFP (10×10 mm, 0.8 mm pitch) package | Preferred where legacy PCB layouts use 44-pin LQFP footprints or thermal dissipation requirements favor larger pad area | Choose for drop-in replacement on existing 44-pin LQFP designs; verify pin mapping compatibility per Table 1-1 |
Compared with R7F100GLJ3CFB#BA0, the R7F100GGJ3CFB#BA0 trades flash/RAM capacity for cost-sensitive deployments; compared with R7F100GGJ3CFA#BA0, it offers finer 0.5 mm pitch and smaller footprint for space-constrained industrial modules - both alternatives retain identical peripheral functionality and SNOOZE/CTSU2L capabilities.

FAQ
What is the maximum operating frequency and corresponding supply voltage range for the R7F100GGJ3CFB#BA0?
The R7F100GGJ3CFB#BA0 operates up to 32 MHz using the 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; accuracy is ±1.0% over -20°C to +85°C and VDD = 1.8–5.5 V. The device also supports ultra-low-speed operation at 32.768 kHz for RTC and deep-sleep timing.
Does the R7F100GGJ3CFB#BA0 support in-system programming and secure firmware updates?
Yes, the R7F100GGJ3CFB#BA0 supports full in-system programming via on-chip debugging interface, including boot swapping and flash shield window protection. Code flash blocks can be individually locked against erase/write, and self-programming is enabled during normal operation - allowing field firmware updates without external programmers while maintaining security-critical sections.
How many capacitive touch channels does the R7F100GGJ3CFB#BA0 support, and what configuration options are available?
The R7F100GGJ3CFB#BA0 integrates the CTSU2L capacitive touch unit supporting up to 32 self-capacitance keys (one pin per key) or 64 mutual-capacitance keys (8×8 matrix). It operates across the full 1.8–5.5 V VDD range and includes automatic noise cancellation and drift compensation - all implemented in hardware without CPU overhead.
What are the key low-power modes supported by the R7F100GGJ3CFB#BA0, and what is the typical current draw in each?
The R7F100GGJ3CFB#BA0 supports HALT (core stopped, peripherals active), STOP (core/peripherals halted, RAM retained), and SNOOZE (peripheral sequencer active, CPU/flash/RAM powered down). Typical currents are 41 µA/MHz in active mode, 210 nA in STOP with 4 KB RAM retention, and sub-µA in SNOOZE mode - enabling multi-year battery life in intermittent-sensing applications.
Can the R7F100GGJ3CFB#BA0 interface directly with 3.3 V or 5 V external peripherals without level-shifting?
Yes, multiple I/O ports on the R7F100GGJ3CFB#BA0 support input-tolerant operation up to 6 V (N-ch open-drain) or VDD-tolerant inputs (10–33 pins depending on variant), and configurable pull-up resistors allow direct interfacing with 1.8 V, 2.5 V, or 3.3 V logic. This eliminates external level shifters in mixed-voltage industrial systems.
