Overview
R7F101G8G2DLA#AC1 from Renesas is a 25-pin WFLGA-packaged RL78/G24 16-bit microcontroller featuring 128 KB code flash, 12 KB RAM, and 4 KB data flash, operating at up to 48 MHz with 50 µA/MHz ultra-low-power consumption. It integrates FAA accelerator, dual 12-bit ADC (23 channels), DALI-2 interface, and KB30/KB31/KB32 complementary PWM timers for digital power supply and lighting control.
For engineers reviewing the R7F101G8G2DLA#AC1 datasheet, R7F101G8G2DLA#AC1 pinout, R7F101G8G2DLA#AC1 application, or R7F101G8G2DLA#AC1 equivalent, key selection criteria include its 25-pin WFLGA (3 × 3 mm) footprint, –40 to +85°C industrial temperature grade, DALI-2 compliance, and integrated programmable gain amplifier for sensor signal conditioning in compact lighting drivers.
Technical Context
The R7F101G8G2DLA#AC1 implements a CISC-based RL78 CPU core with 3-stage pipeline and flexible clocking (48 MHz max via PLL or high-speed on-chip oscillator ±1.0% accuracy). Its Flexible Application Accelerator (FAA) supports 32-bit signed multiply-accumulate operations with 33-bit internal precision and dedicated 32-byte shared memory for CPU–FAA data exchange.
Peripheral integration includes two 12-bit ADCs with simultaneous sampling on two channels, four comparator channels with selectable D/A or external reference, and three 16-bit complementary PWM timers (KB30/KB31/KB32) supporting PFC control, dithering, and 651-ps average resolution at 96 MHz - all optimized for closed-loop digital power and DALI-compliant LED driver designs.

FAQ
What is the maximum operating frequency and clock accuracy of the R7F101G8G2DLA#AC1?
The R7F101G8G2DLA#AC1 achieves a maximum operating frequency of 48 MHz using either the PLL or high-speed on-chip oscillator. Its high-speed oscillator maintains ±1.0% accuracy across VDD = 1.8–5.5 V and ambient temperatures from –20 to +85°C - sufficient for DALI-2 timing compliance and precise PWM generation without external crystals.
Does the R7F101G8G2DLA#AC1 support DALI-2 communication natively?
Yes, the R7F101G8G2DLA#AC1 includes native DALI-2 transceiver functionality on pins P00 (DALITxD0) and P01 (DALIRxD0). No external level-shifting components or transceivers are required, enabling direct connection to the DALI bus with built-in error detection and protocol handling per IEC 62386-102.
What are the memory resources available on the R7F101G8G2DLA#AC1?
The R7F101G8G2DLA#AC1 provides 128 KB of code flash memory (organized in 2 KB blocks with security lock), 12 KB of on-chip RAM, and 4 KB of data flash memory rated for 1,000,000 write/erase cycles. Background operation allows code execution during data flash rewriting - essential for robust firmware updates in deployed R7F101G8G2DLA#AC1 systems.
How does the Flexible Application Accelerator (FAA) enhance performance in power control applications?
The FAA in the R7F101G8G2DLA#AC1 accelerates 32-bit signed multiply-accumulate operations with 33-bit internal precision and dedicated 4 KB code RAM + 2 KB data RAM. In digital power applications, this offloads PID loop computation from the main RL78 CPU, enabling deterministic 100-kHz control loops while maintaining ultra-low active current (50 µA/MHz) for the R7F101G8G2DLA#AC1.
What is the package type and thermal specification for the R7F101G8G2DLA#AC1?
The R7F101G8G2DLA#AC1 uses a 25-pin WFLGA package (3 × 3 mm, 0.50-mm pitch) with an exposed die pad recommended for soldering to a non-electrical thermal pad. It is rated for –40 to +85°C ambient operation (consumer-grade "D" field marking), and requires a 0.47–1 µF capacitor between REGC and VSS for stable internal regulator operation.
