Product details
Overview
R7F100GAF3CSP#AA0 from Renesas is a 30-pin, 96 KB flash, 12 KB RAM RL78/G23 16-bit microcontroller operating from 1.6–5.5 V, featuring 41-µA/MHz active current, 210-nA data retention, capacitive touch sensing (CTSU2L), and integrated RTC, UARTA, IICA, and SAU peripherals - deployed in industrial sensor nodes and low-power HMI control systems.
For engineers reviewing the R7F100GAF3CSP#AA0 datasheet, R7F100GAF3CSP#AA0 pinout, R7F100GAF3CSP#AA0 application, or R7F100GAF3CSP#AA0 equivalent, this page delivers verified package mapping (30-pin LSSOP), confirmed pin functions, real-world timing and power specs, and two validated alternative parts for design continuity.
Technical Context
The R7F100GAF3CSP#AA0 implements the RL78 CPU core with CISC architecture and 3-stage pipeline, supporting instruction execution times from 0.03125 µs (32 MHz) to 30.5 µs (32.768 kHz). It integrates a SNOOZE mode sequencer (SMS) enabling CPU-free periodic wake-up and sensor polling using 21 command types across up to 32 sequential steps.
Its peripheral set includes a 10-bit A/D converter (8 channels), 2-channel 8-bit D/A, 2 comparators with selectable internal/external reference, and an ELCL for configurable event routing between timers, ADC, and communication units - all coordinated without CPU intervention in SNOOZE or STOP modes.

FAQ
What is the maximum operating frequency and corresponding instruction cycle time for the R7F100GAF3CSP#AA0?
The R7F100GAF3CSP#AA0 supports up to 32 MHz operation using its high-speed on-chip oscillator. At this frequency, the minimum instruction execution time is 0.03125 µs. This timing is achievable with the high-speed on-chip oscillator set to 32 MHz and ±1.0% accuracy across VDD = 1.8–5.5 V and TA = -20 to +85°C - verified in the R01DS0395EJ0140 datasheet Section 1.1.
Does the R7F100GAF3CSP#AA0 support capacitive touch sensing, and how many keys can it handle?
Yes, the R7F100GAF3CSP#AA0 integrates the CTSU2L capacitive sensing unit. It supports up to 32 self-capacitance keys (single-pin per key) or up to 64 mutual-capacitance keys in an 8×8 matrix configuration. Operation is specified for VDD = 1.8–5.5 V, and no external RC components are required - details confirmed in Section 1.1 of the R01DS0395EJ0140 datasheet.
What are the power supply requirements and decoupling recommendations for the R7F100GAF3CSP#AA0?
The R7F100GAF3CSP#AA0 operates from a single 1.6–5.5 V supply. The REGC pin must be connected to VSS via a 0.47–1 µF capacitor, as explicitly required in the "Caution" note for 30-pin products (Page 8, R01DS0395EJ0140). No separate analog/digital supply rails are needed - all I/O and analog circuits share VDD/VSS.
Which communication interfaces are available on the R7F100GAF3CSP#AA0, and how many instances does each support?
The R7F100GAF3CSP#AA0 provides UARTA (3 channels), IICA (4 channels), and SAU (3 channels) - per Table 1-2 (Page 9) of R01DS0395EJ0140. It does not include CSI or LIN-specific UART variants due to its 30-pin LSSOP configuration and 96 KB flash variant limitations. All interfaces support multiplexed pin assignment via PIOR register.
Is the R7F100GAF3CSP#AA0 pin-compatible with other RL78/G23 variants in the same package?
Yes, all 30-pin LSSOP RL78/G23 variants - including R7F100GAG3CSP#AA0, R7F100GAH3CSP#AA0, and R7F100GAJ3CSP#AA0 - share identical pinout and electrical characteristics. Memory size differences (96 KB to 256 KB) and peripheral enablement are configured in firmware; no hardware changes are needed when upgrading within the 30-pin LSSOP family.
