Product details
Overview
R7F100GSL3CFB#AA0 from Renesas is a 128-pin, industrial-grade RL78/G23 16-bit microcontroller with 384 KB code flash, 8 KB data flash, and 32 KB RAM, operating from 1.6–5.5 V. It delivers ultra-low power consumption (41 µA/MHz active, 210 nA data retention), integrated capacitive touch sensing (up to 64 keys), and rich peripherals including 16-bit timers, 12-bit ADC (26 channels), dual DAC, RTC, and multiple UART/I²C/SPI interfaces - deployed in battery-powered industrial HMI and sensor node applications.
For engineers reviewing the R7F100GSL3CFB#AA0 datasheet, R7F100GSL3CFB#AA0 pinout, R7F100GSL3CFB#AA0 application, or R7F100GSL3CFB#AA0 equivalent, key selection criteria include its LFQFP-128 (0.5 mm pitch) package, -40°C to +105°C temperature rating, SNOOZE mode sequencer for autonomous low-power sensing, and hardware ELCL for event-driven peripheral coordination without CPU intervention.
Technical Context
The R7F100GSL3CFB#AA0 implements the RL78 CPU core with 3-stage pipeline CISC architecture, supporting configurable instruction execution times from 0.03125 µs (32 MHz high-speed mode) to 30.5 µs (32.768 kHz ultra-low-speed mode). Its power management includes HALT, STOP, and SNOOZE modes, with wake-up from STOP in under 4 µs.
Peripheral integration centers on autonomous operation: the SNOOZE mode sequencer executes up to 32 pre-programmed commands (from 21 available) across ADC sampling, comparator evaluation, and GPIO toggling - all without CPU, RAM, or flash activation. The Event Link Controller (ELCL) enables direct hardware-level signal routing between peripherals (e.g., timer overflow triggering ADC conversion), eliminating software latency and interrupt overhead.

FAQ
What is the maximum operating frequency and corresponding current consumption for the R7F100GSL3CFB#AA0?
The R7F100GSL3CFB#AA0 operates up to 32 MHz using its high-speed on-chip oscillator (±1.0% accuracy). At this frequency and VDD = 3.3 V, typical active current is 41 µA/MHz - resulting in ~1.31 mA total. In STOP mode with 4 KB RAM retention, current drops to 210 nA, enabling multi-year battery life in intermittent-sensing applications.
Does the R7F100GSL3CFB#AA0 support hardware encryption or secure boot features?
The R7F100GSL3CFB#AA0 does not integrate AES, SHA, or dedicated secure boot hardware. It supports flash security features including block erase/write prohibition and boot swapping with flash shield window, enabling basic firmware protection. For cryptographic operations, external secure elements or software libraries leveraging its 16-bit MAC unit are required - confirmed per R01DS0395EJ0140 Section 1.1.
Can the R7F100GSL3CFB#AA0's capacitive touch unit interface with projected-capacitive (PCAP) displays?
No. The R7F100GSL3CFB#AA0's CTSU2L unit supports only self-capacitance (single-touch key detection) and mutual-capacitance (matrix keypad scanning) topologies - not projected-capacitive (PCAP) display controllers requiring dedicated I²C slave interfaces and multi-touch gesture engines. It is intended for buttons, sliders, and proximity sensing, not display overlay integration.
What debug interfaces are available on the R7F100GSL3CFB#AA0, and are they accessible in the 128-pin LFQFP package?
The R7F100GSL3CFB#AA0 supports on-chip debugging via the single-wire SWD interface using pins P40 (TOOL0) and RESET. These signals are fully routed in the 128-pin LFQFP package (PLQP0128KD-A), with no multiplexing conflicts. No JTAG support is provided; SWD enables full breakpoint, watchpoint, and memory access capabilities through standard Renesas E2 emulator hardware.
How many UART channels on the R7F100GSL3CFB#AA0 support LIN 2.2 physical layer compliance, and what hardware features enable it?
The R7F100GSL3CFB#AA0 includes three UARTA channels (RxD0/TxD0, RxD1/TxD1, RxD2/TxD2) with full LIN 2.2 compliance. Hardware features include automatic break detection (sync field recognition), programmable baud rate tolerance (±1.5%), checksum generation/verification (classic and enhanced), and slave node response time control - all implemented in dedicated UARTA peripheral logic without CPU involvement.
