Renesas R7F100GGK2DNP#AA0

Overview

R7F100GGK2DNP#AA0 from Renesas is an RL78/G23 48-pin HWQFN microcontroller with 256 KB code flash, 8 KB data flash, and 24 KB RAM, operating at 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 dual ADC resolution (8/10/12-bit) for battery-powered industrial HMI and sensor interface applications.

For engineers reviewing the R7F100GGK2DNP#AA0 datasheet, R7F100GGK2DNP#AA0 pinout, R7F100GGK2DNP#AA0 application, or R7F100GGK2DNP#AA0 equivalent, key selection criteria include its 48-pin HWQFN-0.5mm package, -40°C to +85°C consumer-grade temperature range, SNOOZE mode sequencer for autonomous low-power sensing, and hardware-accelerated CTSU2L capacitive touch unit.

Technical Context

The R7F100GGK2DNP#AA0 implements the RL78 CPU core with a 3-stage pipeline, supporting instruction execution times from 0.03125 µs (32 MHz high-speed mode) to 30.5 µs (32.768 kHz ultra-low-speed mode). Its SNOOZE mode sequencer executes up to 32 preconfigured commands-including comparisons and calculations-without CPU, RAM, or flash activation, enabling deterministic low-power event processing.

Peripheral integration includes a Logic and Event Link Controller (ELCL) for configurable signal routing between peripherals, a Data Transfer Controller (DTC) supporting chain transfers triggered by interrupts, and a Realtime Clock with alarm and clock correction. The device supports background operation during data flash rewriting (BGO) and features security functions like block erase prohibition.

FAQ

What is the maximum operating frequency of the R7F100GGK2DNP#AA0?

The R7F100GGK2DNP#AA0 supports a maximum CPU operating frequency of 32 MHz using the high-speed on-chip oscillator. At this speed, the minimum instruction execution time is 0.03125 µs. The device also supports ultra-low-speed operation at 32.768 kHz for RTC and low-power monitoring tasks, with a corresponding instruction time of 30.5 µs.

Does the R7F100GGK2DNP#AA0 support hardware-accelerated capacitive touch sensing?

Yes, the R7F100GGK2DNP#AA0 integrates the CTSU2L (Capacitive Touch Sensing Unit Level 2) which provides hardware-accelerated self-capacitance (up to 32 keys) and mutual-capacitance (8×8 matrix, up to 64 keys) sensing. It includes built-in noise cancellation, automatic calibration, and supports operation across the full 1.8–5.5 V supply range-enabling robust touch interfaces without external components.

What package type and pin count does the R7F100GGK2DNP#AA0 use?

The R7F100GGK2DNP#AA0 uses a 48-pin HWQFN (Heat Sink Quad Flat No-lead) package measuring 7 × 7 mm with 0.50-mm pitch and an exposed die pad. This package is optimized for compact PCB layouts and improved thermal performance compared to equivalent LQFP variants, and is designated by the "NP" suffix in the part number.

Can the R7F100GGK2DNP#AA0 perform background data flash writes while executing code from flash memory?

Yes, the R7F100GGK2DNP#AA0 supports Background Operation (BGO) for data flash memory. This allows the CPU to continue executing instructions from code flash memory while simultaneously rewriting data flash-enabling uninterrupted operation during firmware updates, configuration saves, or data logging without system stalls or interrupt masking.

What is the operating temperature range specified for the R7F100GGK2DNP#AA0?

The R7F100GGK2DNP#AA0 is rated for an operating ambient temperature range of -40°C to +85°C, indicated by the "D" (consumer applications) and "2" (TA = -40 to +85°C) fields in its part number encoding. This makes it suitable for commercial and consumer equipment deployed in non-temperature-controlled environments.
