Product details
Overview
R7F100GAH3CSP#AA0 from Renesas is an RL78/G23 30-pin LSSOP microcontroller with 128 KB code flash, 8 KB data flash, and 16 KB RAM, operating from 1.6–5.5 V. It delivers true low-power operation (41 µA/MHz active, 210 nA data retention), integrated capacitive touch sensing (CTSU2L), 12-bit ADC (up to 26 channels), and dual DAC outputs - deployed in battery-powered industrial HMI and sensor node applications.
For engineers reviewing the R7F100GAH3CSP#AA0 datasheet, R7F100GAH3CSP#AA0 pinout, R7F100GAH3CSP#AA0 application, or R7F100GAH3CSP#AA0 equivalent, key selection considerations include its 30-pin LSSOP-0.65mm package, industrial-grade −40°C to +105°C temperature rating (C-suffix), SNOOZE mode sequencer for autonomous low-power sensing, and hardware ELCL for event-driven peripheral coordination without CPU intervention.
Technical Context
The RL78/G23 core implements a CISC architecture with 3-stage pipeline and configurable instruction timing (0.03125 µs at 32 MHz high-speed mode; 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 eight 8-bit general-purpose registers.
Power management includes HALT, STOP, and SNOOZE modes - the latter enabled by a dedicated sequencer executing up to 32 preconfigured commands (from 21 available) to perform analog measurements, comparisons, and wake-up decisions autonomously, bypassing CPU, flash, and RAM usage entirely.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R7F100GBH3CNP#AA0 | Same RL78/G23 core, 32-pin HWQFN package, identical 128 KB/8 KB/16 KB memory, but adds exposed die pad and supports higher pin-count peripheral sets (e.g., extra UART/SAU channels) | Preferred where PCB space is constrained and thermal performance matters; not drop-in due to different footprint and pin count (32 vs. 30) | Select when needing enhanced thermal dissipation or additional serial interfaces; requires layout revision |
| R7F100GAJ3CSP#AA0 | Same 30-pin LSSOP package and industrial temp grade, but upgraded to 192 KB code flash, 8 KB data flash, and 20 KB RAM - same peripheral set and pinout | Drop-in replacement for designs requiring more firmware headroom or larger data buffers without changing PCB or firmware drivers | Choose when future firmware growth or extended data logging is anticipated; fully pin-compatible and functionally identical except memory size |
Compared with R7F100GAH3CSP#AA0, R7F100GBH3CNP#AA0 offers superior thermal performance and peripheral scalability in a smaller footprint but demands PCB redesign, while R7F100GAJ3CSP#AA0 provides immediate memory headroom uplift with zero hardware changes - making it the preferred upgrade path for existing LSSOP-based designs.

FAQ
What is the maximum operating frequency and corresponding current consumption of the R7F100GAH3CSP#AA0?
The R7F100GAH3CSP#AA0 operates up to 32 MHz using its high-speed on-chip oscillator (±1.0% accuracy). At this frequency and 3.3 V supply, typical active current is 41 µA/MHz - resulting in ~1.3 mA total at full speed. In STOP mode, current drops to 290 nA (typ.), and data retention at 4 KB RAM consumes just 210 nA.
Does the R7F100GAH3CSP#AA0 support hardware debugging, and what interface is used?
Yes, the R7F100GAH3CSP#AA0 supports on-chip debugging via the dedicated TOOL0 (pin 5) and TOOLRxD/TOOLTxD (pins 25/24) signals. It uses Renesas' standard FINE debug interface compatible with E2 studio, CS+ and J-Link debug probes - no external debug header required.
Can the R7F100GAH3CSP#AA0's capacitive touch unit operate reliably in high-noise industrial environments?
Yes, the CTSU2L unit in the R7F100GAH3CSP#AA0 includes adaptive noise cancellation, shield electrode support, and programmable scan parameters (frequency, gain, cycle count). Benchmarks show stable operation under 10 Vpp conducted noise and 3 kV ESD - validated per IEC 61000-4-2/4-4 in industrial HMI reference designs.
What packaging and temperature specifications apply to the R7F100GAH3CSP#AA0?
The R7F100GAH3CSP#AA0 uses a 30-pin plastic LSSOP package (7.62 mm body width, 0.65 mm lead pitch) with industrial temperature rating (−40°C to +105°C), indicated by the "C" suffix. The "#AA0" denotes tray packaging per JEDEC standards for automated assembly.
Is the R7F100GAH3CSP#AA0 pin-compatible with other RL78/G23 variants in the same package family?
Yes - all RL78/G23 devices in the 30-pin LSSOP package (e.g., R7F100GAF3CSP#AA0, R7F100GAG3CSP#AA0, R7F100GAJ3CSP#AA0) share identical pinout, electrical characteristics, and peripheral mapping. Only memory sizes and minor feature enablings differ; firmware and PCB are fully interchangeable across this pin-compatible group.
