Product details
Overview
R7F100GLF3CFA#HA0 from Renesas is a 64-pin LQFP-packaged RL78/G23 16-bit microcontroller with 512 KB code flash, 8 KB data flash, and 48 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 (CTSU2L), RTC, 16-bit TAU timers, and multiple serial interfaces including UARTA, IICA, and SAU for industrial control and sensor node applications.
For engineers reviewing the R7F100GLF3CFA#HA0 datasheet, R7F100GLF3CFA#HA0 pinout, R7F100GLF3CFA#HA0 application, or R7F100GLF3CFA#HA0 equivalent, key selection criteria include its 64-pin LQFP-0.65mm package, industrial-grade −40 to +105°C operation, 512 KB flash/48 KB RAM memory configuration, and support for SNOOZE mode sequencer and ELCL event linking in resource-constrained embedded systems.
Technical Context
The RL78/G23 core implements a CISC architecture with 3-stage pipeline and configurable instruction timing (0.03125 µs min @ 32 MHz high-speed clock or 30.5 µs @ 32.768 kHz subsystem clock). It integrates a SNOOZE mode sequencer (SMS) supporting up to 32 sequential low-power operations without CPU wake-up, and an Event Link Controller (ELCL) enabling hardware-triggered peripheral coordination without software intervention.
Power management includes HALT, STOP, and SNOOZE modes with fast STOP-mode wakeup, POR, dual voltage detectors (LVD0/LVD1), and a 32.768 kHz low-speed oscillator with adjustability. The device supports background data flash rewriting (BGO) and self-programming with boot swapping and flash shield window security.

The R7F100GLF3CFA#HA0 operates at up to 32 MHz using the high-speed on-chip oscillator, with guaranteed functionality across its full 1.6–5.5 V supply range. At 32 MHz, minimum instruction execution time is 0.03125 µs. The device maintains timing specifications over the full industrial temperature range of −40 to +105°C, and oscillator accuracy is ±1.0% at VDD = 1.8–5.5 V and TA = −20 to +85°C.
Does the R7F100GLF3CFA#HA0 support hardware debugging, and what interface is used?
Yes, the R7F100GLF3CFA#HA0 supports on-chip debugging via the single-wire debug (SWD) interface using the TOOL0 and TOOLRxD/TOOLTxD pins. It is compatible with Renesas E2 emulator and E2 studio IDE. Debugging features include breakpoint setting, watchpoint monitoring, memory/register read/write, and real-time trace via the on-chip debug module-no external debug probe required beyond standard SWD cabling.
How many capacitive touch sensing channels does the R7F100GLF3CFA#HA0 support, and what configurations are available?
The R7F100GLF3CFA#HA0 integrates the CTSU2L unit supporting up to 32 self-capacitance keys (single-pin per key) or 64 mutual-capacitance keys (8×8 matrix). It operates at VDD = 1.8–5.5 V and includes built-in noise cancellation, auto-calibration, and proximity detection. Pin assignments are flexible via the CTSU register set, and all supported touch pins are defined in the 64-pin LQFP pinout-including P30 (TSCAP), P70–P73, and P20–P26.

The R7F100GLF3CFA#HA0 integrates UARTA (3 channels), simplified SPI (CSI, 3 channels), I²C (IICA, 4 channels), and SAU-based serial interfaces (up to 6 channels total). UARTA supports LIN-bus physical layer compliance. All interfaces are multiplexed onto GPIO pins and configurable via peripheral I/O redirection registers (PIOR). No external transceivers are needed for basic point-to-point communication, though RS-485 or CAN require external drivers.
Is the R7F100GLF3CFA#HA0 pin-compatible with other RL78/G23 variants in the same package, and what memory options share the same 64-pin LQFP footprint?
Yes, all RL78/G23 devices in the 64-pin LQFP-0.65mm package (order codes ending in CFA) are pin-compatible, including R7F100GLF3CFA#HA0 (512 KB flash/48 KB RAM), R7F100GLL3CFA#HA0 (512 KB/32 KB), R7F100GLK3CFA#HA0 (384 KB/24 KB), and R7F100GLJ3CFA#HA0 (256 KB/20 KB). Pin functions, power, clock, and debug signals are identical-only memory size and some peripheral counts differ.
