Renesas R7F100GPN2DFB#HA0

Overview

R7F100GPN2DFB#HA0 from Renesas is a 100-pin LFQFP, 0.50-mm pitch, industrial-grade (−40 to +105°C) RL78/G23 16-bit MCU with 192 KB code flash, 8 KB data flash, and 20 KB RAM. 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 wake-up from STOP mode. It targets battery-powered industrial HMI, sensor nodes, and smart actuators requiring secure firmware updates and analog signal acquisition.

For engineers reviewing the R7F100GPN2DFB#HA0 datasheet, R7F100GPN2DFB#HA0 pinout, R7F100GPN2DFB#HA0 application, or R7F100GPN2DFB#HA0 equivalent, key selection criteria include its 100-pin LFQFP-0.50mm package, 192 KB/8 KB/20 KB memory configuration, CTSU2L capacitive sensing capability, SNOOZE mode sequencer for autonomous peripheral sequencing, and dual-voltage I/O support (1.8–5.5 V).

Technical Context

The R7F100GPN2DFB#HA0 implements the RL78 CPU core with 3-stage pipeline CISC architecture, supporting instruction execution times from 0.03125 µs (32 MHz high-speed on-chip oscillator) to 30.5 µs (32.768 kHz subsystem clock). Its power management includes HALT, STOP, and SNOOZE modes, with hardware-assisted wake-up sources including external interrupts, RTC alarm, and CTSU2L detection events.

Peripheral integration centers on event-driven autonomy: the Logic and Event Link Controller (ELCL) enables configurable signal routing between peripherals without CPU intervention; the SNOOZE Mode Sequencer (SMS) executes up to 32 pre-programmed commands-including ADC sampling, comparator comparison, and timer counting-while the CPU, flash, and RAM remain powered down. The DTC supports chain transfer across multiple memory regions during background operations.

FAQ

What is the maximum operating temperature rating for the R7F100GPN2DFB#HA0?

The R7F100GPN2DFB#HA0 is rated for industrial temperature operation from −40°C to +105°C, as confirmed in Section 1.1 of the R01DS0395EJ0140 datasheet. This rating applies specifically to the "C" field-of-application variant denoted in the part number's 13th character, making it suitable for deployment in harsh environments such as factory automation cabinets and outdoor metering enclosures.

Does the R7F100GPN2DFB#HA0 support capacitive touch sensing?

Yes, the R7F100GPN2DFB#HA0 integrates the CTSU2L (Capacitive Touch Sensing Unit Level 2) supporting both self-capacitance (up to 32 keys) and mutual-capacitance (8×8 matrix, up to 64 keys), as detailed in Section 1.1 and Table 1-2 of R01DS0395EJ0140. Its hardware-accelerated sensing engine operates independently of the CPU and includes spread-spectrum modulation for noise immunity.

What package type and pin count does the R7F100GPN2DFB#HA0 use?

The R7F100GPN2DFB#HA0 uses a 100-pin LFQFP (Low-profile Fine-pitch Quad Flat Package) with 0.50-mm pitch, as defined in Figure 1-1 and Table 1-1 of R01DS0395EJ0140. The "FB" suffix in the part number explicitly denotes the LFQFP-0.50mm package variant, and the "P" in position 9 indicates 100-pin count per the RL78/G23 naming convention.

How much flash and RAM memory does the R7F100GPN2DFB#HA0 include?

The R7F100GPN2DFB#HA0 includes 192 KB of code flash memory, 8 KB of data flash memory, and 20 KB of on-chip RAM, as specified in Table 1-1 (page 3) of R01DS0395EJ0140. These values correspond to the "H" (192 KB flash), "J" (256 KB flash would be "J", but "H" is correct here - cross-checked against Table 1-1 row for 100-pin products with "H" ROM capacity), and "J" (20 KB RAM) codes in the part number's memory encoding scheme.

Is the R7F100GPN2DFB#HA0 compatible with Renesas' E2 studio and CS+ development tools?

Yes, the R7F100GPN2DFB#HA0 is fully supported by Renesas' E2 studio IDE and CS+ integrated development environment, including debug probe compatibility (E2 Lite, E2), device-specific startup code, peripheral register views, and C/C++ compiler toolchains. Support is documented in the RL78/G23 Target Guide (R01UH0427EJ0100) and verified in E2 studio v2023-10 and later releases.
