Product details
Overview
R7F102GGE2DFB#HA0 from Renesas is a 48-pin LFQFP, 5.0-V tolerant RL78/G22 16-bit microcontroller with 64 KB code flash, 4 KB RAM, and 2 KB data flash, operating from 1.6 to 5.5 V. It delivers true low-power operation (37.5 µA/MHz active, 200 nA STOP), integrates 10-channel 10-bit ADC, RTC, capacitive touch sensing (up to 29 keys), and multiple serial interfaces for embedded control in industrial HMI and sensor nodes.
For engineers reviewing the R7F102GGE2DFB#HA0 datasheet, R7F102GGE2DFB#HA0 pinout, R7F102GGE2DFB#HA0 application, or R7F102GGE2DFB#HA0 equivalent, key selection criteria include its 48-pin LFQFP-0.5 mm pitch package, -40°C to +105°C industrial temperature grade, 64 KB flash with self-programming and flash shield window, and support for SNOOZE mode sequencer for ultra-low-power event-driven wake-up without CPU involvement.
Technical Context
The RL78/G22 core implements a CISC architecture with 3-stage pipeline and configurable instruction timing-enabling 0.03125 µs min. execution at 32 MHz (high-speed on-chip oscillator) or 30.5 µs at 32.768 kHz (subsystem clock). It supports multiply/divide/accumulate instructions and a 1 MB address space.
Peripherals include an Event Link Controller (ELC) routing 20 event signals between peripherals, a Data Transfer Controller (DTC) with chain transfer, and a dedicated SNOOZE Mode Sequencer (SMS) executing up to 32 preconfigured commands-including comparisons and calculations-entirely without CPU, flash, or RAM activation.

Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R7F102GGC2DFB | 32 KB code flash (vs. 64 KB), same 48-pin LFQFP-0.5 mm, identical peripherals and temperature grade | Suitable where firmware size ≤30 KB and no future feature expansion is planned | Select when cost sensitivity outweighs headroom for bootloader, OTA updates, or multi-language UI assets |
| RA2A1GBM20FB#AC0 | Arm® Cortex®-M23 core, 128 KB flash, 32 KB SRAM, 12-bit ADC, but no integrated CTSU or SNOOZE sequencer | Better for complex connectivity (USB, CAN) or cryptographic acceleration; lacks autonomous low-power sensing capability | Choose only if migrating to Arm ecosystem, requiring TrustZone, or needing >64 KB code space-accept trade-off of higher active power and missing SMS/CTSU hardware |

R7F102GGE2DFB#HA0 features a 10-bit ADC with up to 10 analog input channels. It supports internal 1.48 V reference (typ.), AVREFP/AVREFM differential reference, and VDD as reference-enabling flexible precision measurement across sensor types without external voltage references.
Can R7F102GGE2DFB#HA0 execute code while rewriting data flash memory?
Yes. R7F102GGE2DFB#HA0 supports Background Operation (BGO) for its 2 KB data flash. Code can be executed from program memory while data flash is being rewritten, allowing real-time parameter updates (e.g., calibration coefficients, configuration flags) without halting application execution.
What packaging and temperature grade does R7F102GGE2DFB#HA0 use, and how is it marked for industrial applications?
R7F102GGE2DFB#HA0 uses a 48-pin LFQFP package (7 × 7 mm, 0.50-mm pitch) with embossed tape packaging (#HA0).
