Renesas R7F102G8C2DLA#BC0

Overview

R7F102G8C2DLA#BC0 from Renesas is a 25-pin WFLGA-packaged RL78/G22 16-bit microcontroller with 32 KB code flash, 4 KB RAM, and 2 KB data flash, operating from 1.6 to 5.5 V. It delivers ultra-low power consumption (37.5 µA/MHz active, 200 nA STOP mode), integrates 10-channel 10-bit ADC, RTC, capacitive touch sensing (up to 29 keys), and supports UART, I²C, and SPI interfaces for battery-powered HMI and industrial control applications.

For engineers reviewing the R7F102G8C2DLA#BC0 datasheet, R7F102G8C2DLA#BC0 pinout, R7F102G8C2DLA#BC0 application, or R7F102G8C2DLA#BC0 equivalent, this page provides verified package mapping (25-pin WFLGA, 3 × 3 mm, 0.50-mm pitch), confirmed low-power operating modes, validated CTSU2La capacitive sensing capability, and real-world timing/peripheral configuration constraints per Renesas R01DS0424EJ0120 Rev.1.20.

Technical Context

The R7F102G8C2DLA#BC0 implements the RL78 CPU core with 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 low-power processes using 21 command types without CPU, flash, or RAM activation.

Peripheral integration includes a 16-bit timer array unit (TAU) with 8 channels, 32-bit interval timer, real-time clock with alarm and correction, watchdog timer, and event link controller (ELC) enabling 20 configurable inter-peripheral event signals - all operating within the -40°C to +85°C ambient range under consumer-grade qualification (D-field).

FAQ

What is the maximum operating frequency of the R7F102G8C2DLA#BC0?

The R7F102G8C2DLA#BC0 supports up to 32 MHz operation using its high-speed on-chip oscillator with ±1.0% accuracy across 1.8–5.5 V and -20°C to +85°C. External crystal or clock sources can also drive the core at higher frequencies if configured via the system clock control registers, but 32 MHz is the guaranteed maximum for on-chip oscillator operation per R01DS0424EJ0120 Rev.1.20.

Does the R7F102G8C2DLA#BC0 support capacitive touch sensing?

Yes, the R7F102G8C2DLA#BC0 integrates the CTSU2La capacitive touch sensing unit, supporting up to 29 keys using either self-capacitance (single-pin per key) or mutual-capacitance (matrix configuration) methods. All 25 pins are available for CTSU use, and the unit operates independently of the CPU in STOP or SNOOZE mode, as confirmed in Section 1.1 and Table 1-5 of the datasheet.

What package type and dimensions does the R7F102G8C2DLA#BC0 use?

The R7F102G8C2DLA#BC0 uses a 25-pin WFLGA package measuring 3 mm × 3 mm with 0.50-mm pitch and an exposed die pad. This is explicitly defined in Table 1-1 and Figure 1-1 of R01DS0424EJ0120 Rev.1.20, and the #BC0 suffix denotes tray packaging for WFLGA devices per Renesas ordering conventions.

Can the R7F102G8C2DLA#BC0 operate from a 1.8 V supply?

Yes, the R7F102G8C2DLA#BC0 operates across 1.6 V to 5.5 V, including 1.8 V. At 1.8 V, the high-speed oscillator accuracy remains ±1.0% (per Section 1.1), and all peripherals - including the 10-bit ADC with internal 1.48 V reference and CTSU2La - function fully, enabling compatibility with single-cell Li-ion or NiMH battery systems.

How many UART channels does the R7F102G8C2DLA#BC0 support?

The R7F102G8C2DLA#BC0 supports up to 4 UART/UARTA channels, with channel count dependent on pin multiplexing. In its 25-pin WFLGA configuration, it implements UARTA0 (P11/P12), UARTA1 (P00/P01), and optionally UARTA2 (P13/P14) via peripheral I/O redirection - totaling three functional UART interfaces usable simultaneously, as detailed in Table 1-5 and Section 1.2 of the datasheet.
