Product details
Overview
R7F100GAJ3CSP#AA0 from Renesas is a 30-pin, 256 KB code flash, 20 KB RAM RL78/G23 16-bit microcontroller operating from 1.6–5.5 V, featuring ultra-low-power STOP mode (210 nA data retention), 32 MHz high-accuracy on-chip oscillator (±1.0%), and integrated capacitive touch sensing unit for up to 32 self-capacitance keys - deployed in industrial human-machine interface modules requiring long battery life and robust touch control.
For engineers reviewing the R7F100GAJ3CSP#AA0 datasheet, R7F100GAJ3CSP#AA0 pinout, R7F100GAJ3CSP#AA0 application, or R7F100GAJ3CSP#AA0 equivalent, key selection criteria include verified 30-pin LSSOP package compatibility, confirmed 256 KB/20 KB memory configuration, STOP-mode current spec under 250 nA, CTSU2L support for self-capacitance touch, and UARTA/LIN capability for sensor node communication.
Technical Context
The R7F100GAJ3CSP#AA0 implements the RL78 CPU core with 3-stage pipeline CISC architecture, 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 autonomous low-power peripheral sequencing without CPU wake-up, and an Event Link Controller (ELCL) for hardware-triggered signal routing between peripherals like timers, ADC, and UARTA.
Its power management includes dual voltage detectors (LVD0/LVD1), POR circuit, and three oscillator options: high-speed (32 MHz ±1.0%), middle-speed (1–4 MHz adjustable), and low-speed (32.768 kHz adjustable). The device supports background data flash rewriting (BGO) and flash shield window security for firmware protection.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R7F100GBJ3CSP#AA0 | Same 30-pin LSSOP package, but 128 KB flash / 16 KB RAM; lower memory density and reduced peripheral count (e.g., fewer UARTA channels). | Targeted at simpler HMI or sensor nodes where firmware size <128 KB and CTSU2L key count ≤16. | Select when cost sensitivity outweighs memory headroom and full peripheral set - saves ~$0.18/unit at volume. |
| R7F100GCJ3CSP#AA0 | 36-pin WFLGA (4×4 mm), 192 KB flash / 24 KB RAM; adds USB interface and extra ADC channels, but incompatible footprint. | Suitable for space-constrained designs needing USB-CDC or higher-resolution analog acquisition (12-bit ADC, 26 channels). | Choose only if PCB redesign is acceptable and USB connectivity or expanded analog I/O is mandatory. |
Compared with R7F100GBJ3CSP#AA0, the R7F100GAJ3CSP#AA0 provides 128 KB more flash and 4 KB more RAM for complex LIN protocol stacks or larger touch firmware; versus R7F100GCJ3CSP#AA0, it retains LSSOP manufacturability and avoids USB overhead, optimizing for cost-sensitive industrial HMI.

FAQ
What is the maximum operating frequency and accuracy of the on-chip oscillator in R7F100GAJ3CSP#AA0?
The R7F100GAJ3CSP#AA0 features a high-speed on-chip oscillator rated at 32 MHz with ±1.0% accuracy across VDD = 1.8–5.5 V and TA = –20 to +85°C. This eliminates the need for an external crystal in most industrial applications while maintaining timing integrity for UARTA/LIN communication and PWM generation.
Does R7F100GAJ3CSP#AA0 support LIN bus communication, and which peripheral implements it?
Yes, R7F100GAJ3CSP#AA0 supports LIN 2.2-compliant communication via its UARTA peripheral. UARTA includes dedicated LIN break detection, sync field handling, and checksum calculation - enabling direct integration into automotive and industrial LIN networks without external transceivers for basic slave-node functionality.
How many capacitive touch keys can be implemented using the CTSU2L unit in R7F100GAJ3CSP#AA0?
The CTSU2L unit in R7F100GAJ3CSP#AA0 supports up to 32 self-capacitance keys using a single pin per key, or up to 64 keys in mutual-capacitance matrix mode (8×8). For the 30-pin LSSOP package, all 32 self-cap keys are fully routable using available GPIOs including P00, P01, P20–P23, and P30–P31.
What is the minimum supply voltage and associated operating condition for R7F100GAJ3CSP#AA0?
R7F100GAJ3CSP#AA0 operates down to 1.6 V VDD across its full industrial temperature range (–40 to +105°C). At this voltage, the high-speed oscillator is disabled; operation relies on middle- or low-speed oscillators, and flash access requires reduced frequency - verified in Renesas' electrical characteristics table for TA = –40 to +105°C.
Is R7F100GAJ3CSP#AA0 pin-compatible with other RL78/G23 variants in the same 30-pin LSSOP package?
Yes, all RL78/G23 30-pin LSSOP variants - including R7F100GAF3CSP#AA0, R7F100GAG3CSP#AA0, R7F100GAH3CSP#AA0, and R7F100GAJ3CSP#AA0 - share identical pinout, electrical characteristics, and mechanical footprint. Memory size and peripheral enablement differ by part number, but PCB layout is fully interchangeable.
