Product details
Overview
R7F100GFK3CFP#HA0 from Renesas is a 44-pin LQFP-packaged RL78/G23 16-bit microcontroller with 256 KB code flash, 8 KB data flash, and 24 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), 12-bit ADC (26 channels), dual DAC, RTC, and multiple serial interfaces - deployed in industrial human-machine interface and sensor node applications.
For engineers reviewing the R7F100GFK3CFP#HA0 datasheet, R7F100GFK3CFP#HA0 pinout, R7F100GFK3CFP#HA0 application, or R7F100GFK3CFP#HA0 equivalent, key selection criteria include its 44-pin LQFP-0.8 mm pitch package, -40°C to +105°C industrial temperature grade, 256 KB flash/24 KB RAM memory configuration, and support for SNOOZE mode sequencer and ELCL event linking without CPU intervention.
Technical Context
The R7F100GFK3CFP#HA0 implements the RL78 CPU core with CISC architecture and 3-stage pipeline, supporting configurable 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 STOP-mode wakeup in under 4 µs and SNOOZE sequencer enabling autonomous low-power peripheral sequencing using 32 preloaded commands.
Peripheral integration includes a Logic and Event Link Controller (ELCL) for hardware-triggered signal routing between peripherals, a Data Transfer Controller (DTC) supporting chain transfers, and a Capacitive Touch Sensing Unit (CTSU2L) supporting both self- and mutual-capacitance methods - all operating independently of CPU execution to minimize active power use.

FAQ
What is the maximum operating frequency and corresponding current consumption of the R7F100GFK3CFP#HA0?
The R7F100GFK3CFP#HA0 operates up to 32 MHz using its high-speed on-chip oscillator, achieving 41 µA/MHz typical active current. At full speed, this equates to approximately 1.31 mA total active current (32 MHz × 41 µA/MHz), verified per R01DS0395EJ0140 Rev.1.40 Section 1.1. This value assumes VDD = 3.3 V and TA = 25°C, with all peripherals disabled except CPU core.
Does the R7F100GFK3CFP#HA0 support hardware-based capacitive touch sensing without external components?
Yes, the R7F100GFK3CFP#HA0 integrates the CTSU2L capacitive touch sensing unit supporting both self-capacitance (up to 32 keys) and mutual-capacitance (8×8 matrix, up to 64 keys) configurations. It requires only external RC networks on designated pins (e.g., P30 for TSCAP) and no dedicated touch controller IC - confirmed in Section 1.1 and Figure 1-1 of R01DS0395EJ0140 Rev.1.40.
What debug interface does the R7F100GFK3CFP#HA0 use, and which pins are required?
The R7F100GFK3CFP#HA0 uses the on-chip debug interface accessible via the TOOL0 (P40) and TOOLRxD/TOOLTxD (P11/P12) pins in 3-wire SWD mode. These pins also serve as general-purpose I/O when debug is disabled. Full debug functionality - including flash programming and real-time trace - is supported without additional hardware, as specified in Section 1.3.4 and Table 1-5 of R01DS0395EJ0140 Rev.1.40.
Can the R7F100GFK3CFP#HA0 execute code while rewriting its data flash memory?
Yes, the R7F100GFK3CFP#HA0 supports Background Operation (BGO) for its 8 KB data flash memory. Instructions can be fetched and executed from code flash while data flash is being rewritten - enabling seamless firmware updates and parameter logging without halting real-time tasks. This is documented in Section 1.1 "Data flash memory" and confirmed in the BGO functional description of R01DS0395EJ0140 Rev.1.40.
What is the qualified temperature range and industrial compliance status of the R7F100GFK3CFP#HA0?
The R7F100GFK3CFP#HA0 is rated for -40°C to +105°C ambient operation (3C grade), qualified per industrial standards including AEC-Q100 stress testing for reliability. Its ordering code suffix "C" denotes industrial field-of-application, and "3" specifies the extended temperature range - explicitly defined in Figure 1-1 and Table 1-1 of R01DS0395EJ0140 Rev.1.40.
