Product details
Overview
R7F102G6E3CSP#CA0 from Renesas is a 20-pin LSSOP-packaged RL78/G22 16-bit microcontroller with 64 KB code flash, 4 KB RAM, and 2 KB data flash, operating from 1.6 V to 5.5 V. It delivers true low-power performance (37.5 µA/MHz active, 200 nA STOP mode) and integrates capacitive touch sensing (up to 29 keys), RTC, UART/I²C/SPI interfaces, and 10-channel 10-bit ADC - ideal for battery-powered industrial HMI and sensor nodes.
For engineers reviewing the R7F102G6E3CSP#CA0 datasheet, R7F102G6E3CSP#CA0 pinout, R7F102G6E3CSP#CA0 application, or R7F102G6E3CSP#CA0 equivalent, this page provides verified technical context, validated pin functions, real-world use cases, and confirmed alternative options for design-in and supply continuity planning.
Technical Context
The R7F102G6E3CSP#CA0 implements the RL78 CPU core with CISC architecture, 3-stage pipeline, and configurable instruction timing (0.03125 µs at 32 MHz high-speed mode or 30.5 µs at 32.768 kHz ultra-low-speed mode). It supports multiply/divide/accumulate instructions and features a 1 MB address space with four banks of 8-bit general-purpose registers.
Its peripheral set includes a SNOOZE mode sequencer (SMS) enabling CPU-free intermittent operation using 21 command types across up to 32 processes, plus an Event Link Controller (ELC) routing 20 event signals between peripherals without CPU intervention - both critical for deterministic low-power state management in embedded control.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R7F102G6C3CSP#CA0 | 32 KB code flash (vs. 64 KB), identical package, pinout, and peripheral set | Lower memory footprint suits simpler firmware with minimal GUI or protocol stacks | Select when application code size remains under 28 KB and future feature expansion is unlikely |
| R7F102G7E3CNP#AA0 | 24-pin HWQFN package, adds P60/P61 I²C pins, retains 64 KB flash and same core/peripherals | Requires PCB redesign but enables dedicated I²C bus for external sensors without multiplexing | Choose when additional I²C bandwidth or GPIO count justifies layout change and thermal margin permits 4×4 mm footprint |
Compared with R7F102G6C3CSP#CA0, the R7F102G6E3CSP#CA0 provides double code flash for complex HMI or protocol stacks; versus R7F102G7E3CNP#AA0, it trades two GPIOs and dedicated I²C for smaller LSSOP footprint and lower assembly cost in space-constrained designs.

FAQ
What is the maximum operating frequency and voltage range supported by the R7F102G6E3CSP#CA0?
The R7F102G6E3CSP#CA0 operates at up to 32 MHz using its high-speed on-chip oscillator and supports a wide supply range of 1.6 V to 5.5 V. Its ±1.0% oscillator accuracy over -40°C to +85°C ensures reliable timing for UART communication and real-time control without external crystals in many applications.
Does the R7F102G6E3CSP#CA0 include hardware support for capacitive touch sensing?
Yes, the R7F102G6E3CSP#CA0 integrates the CTSU2La capacitive touch sensing unit, supporting up to 29 self-capacitance keys or matrix mutual-capacitance configurations. It operates across the full 1.8–5.5 V VDD range and requires no external components - enabling robust touch UIs with minimal BOM cost.
How does the SNOOZE mode sequencer (SMS) function in the R7F102G6E3CSP#CA0?
The SMS in the R7F102G6E3CSP#CA0 executes up to 32 predefined operations - including CTSU scans, RTC alarms, and timer comparisons - without CPU involvement. This autonomous sequencing reduces average current consumption and eliminates wake-up latency, making it ideal for periodic sensor polling in battery-powered devices.
Can the R7F102G6E3CSP#CA0 perform ADC conversions while running from data flash or during STOP mode?
No - ADC operation requires the CPU to be active and clocked. However, the R7F102G6E3CSP#CA0 supports Background Operation (BGO) for data flash rewriting while executing code from main flash, and its STOP mode can be exited in under 4 µs to initiate rapid ADC sampling upon external trigger or RTC alarm.
What debug interface options are available on the R7F102G6E3CSP#CA0?
The R7F102G6E3CSP#CA0 provides a dedicated TOOL0 pin (P40) for on-chip debugging and programming via Renesas E2 studio and E2 Lite emulator. It supports full SWD-style functionality including breakpoints, watchpoints, and real-time variable monitoring without requiring additional debug headers or pins.
