Product details
Overview
R7F100GEJ2DNP#AA0 from Renesas is a 40-pin HWQFN-packaged RL78/G23 16-bit MCU with 256 KB code flash, 8 KB data flash, and 24 KB RAM, operating at 1.6–5.5 V. It delivers true low-power operation (41 µA/MHz active, 210 nA data retention), integrated capacitive touch sensing (CTSU2L), and dual-clock domain support for ultra-low-power SNOOZE mode sequencing in battery-powered consumer electronics.
For engineers reviewing the R7F100GEJ2DNP#AA0 datasheet, R7F100GEJ2DNP#AA0 pinout, R7F100GEJ2DNP#AA0 application, or R7F100GEJ2DNP#AA0 equivalent, key selection criteria include its 40-pin HWQFN-0.5mm package, 256 KB flash/24 KB RAM memory configuration, CTSU2L capacitive sensing capability, and verified support for STOP/SNOOZE modes with sub-µA wake-up latency.
Technical Context
The R7F100GEJ2DNP#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). Its power management includes HALT, STOP, and SNOOZE modes, with the latter enabled by a dedicated sequencer that executes up to 32 low-overhead commands without CPU involvement.
Peripheral integration includes 16-bit TAU timers (12 channels), RTC with alarm and correction, 12-bit ADC (up to 26 channels), 8-bit DAC (2 channels), 2-channel comparator, and flexible serial interfaces: up to 10 I²C/Simplified I²C, 6 UART/UARTA (LIN-capable), and 8 CSI/SPI channels - all configurable via peripheral I/O redirection register (PIOR).

FAQ
What is the maximum operating frequency and voltage range supported by the R7F100GEJ2DNP#AA0?
The R7F100GEJ2DNP#AA0 operates at up to 32 MHz using its high-speed on-chip oscillator with ±1.0% accuracy across 1.8–5.5 V. Its absolute maximum supply voltage is 6.0 V, and minimum functional voltage is 1.6 V-enabling direct use with single-cell Li-ion, 3×AA, or wide-range industrial rails. The R7F100GEJ2DNP#AA0 maintains full peripheral functionality across this entire range.
Does the R7F100GEJ2DNP#AA0 support hardware-accelerated capacitive touch sensing?
Yes, the R7F100GEJ2DNP#AA0 integrates the CTSU2L (Capacitive Touch Sensing Unit Level 2) which performs self-capacitance (up to 32 keys) and mutual-capacitance (8×8 matrix) measurements in hardware. It requires no external RC components, supports automatic noise cancellation, and operates independently of the CPU-allowing touch scanning during SNOOZE mode. This capability is confirmed in the R7F100GEJ2DNP#AA0 datasheet Section 1.1 and Table 1-2.
How many serial communication interfaces does the R7F100GEJ2DNP#AA0 provide, and what protocols are supported?
The R7F100GEJ2DNP#AA0 provides up to 10 I²C/Simplified I²C channels, 6 UART/UARTA interfaces (with LIN-bus support), and 8 CSI/SPI channels-all configurable via PIOR. Specific channel counts depend on pin multiplexing; the 40-pin HWQFN variant supports at least 4 I²C, 3 UARTA, and 4 CSI instances simultaneously. These interfaces are fully documented in the R7F100GEJ2DNP#AA0 datasheet Section 1.1 and Table 1-5.
What debug and programming interfaces are available on the R7F100GEJ2DNP#AA0?
The R7F100GEJ2DNP#AA0 supports on-chip debugging via the TOOL0 (pin 1), TOOLRxD (P11), and TOOLTxD (P12) signals, compatible with Renesas E2 emulator and E2 studio IDE. It also supports self-programming of code and data flash with boot swapping and flash shield window security. No external JTAG adapter is required-the R7F100GEJ2DNP#AA0 uses a 2-wire SWD-like debug interface routed through standard GPIO pins.
Is the R7F100GEJ2DNP#AA0 pin-compatible with other RL78/G23 family members in the same package?
Yes, all RL78/G23 devices in the 40-pin HWQFN package-including R7F100GEF2DNP#AA0, R7F100GEG2DNP#AA0, R7F100GEH2DNP#AA0, and R7F100GEJ2DNP#AA0-share identical pinouts, electrical characteristics, and mechanical dimensions. Memory size and peripheral enablement differ by part number, but PCB layout and signal routing remain fully interchangeable across this 40-pin HWQFN subgroup.
