Product details
Overview
R7F101G6E2DSP#CA1 from Renesas is a 20-pin LSSOP-packaged RL78/G24 16-bit microcontroller with 64 KB code flash, 4 KB data flash, and 12 KB RAM, operating at up to 48 MHz with 50-µA/MHz ultra-low-power consumption. It integrates FAA accelerator, 12-bit ADC (23 channels), dual DAC, four comparators, programmable gain amplifier, DALI-2 interface, and timers optimized for motor control and digital power supply.
For engineers reviewing the R7F101G6E2DSP#CA1 datasheet, R7F101G6E2DSP#CA1 pinout, R7F101G6E2DSP#CA1 application, or R7F101G6E2DSP#CA1 equivalent, key selection criteria include its 20-pin LSSOP package, –40°C to +85°C industrial temperature grade, integrated DALI-2 and PMBus/SMBus support, and flexible low-power modes (HALT/STOP/SNOOZE) for lighting and embedded control designs.
Technical Context
The R7F101G6E2DSP#CA1 implements the RL78 CPU core with CISC architecture and 3-stage pipeline, supporting instruction execution times from 0.02083 µs (48 MHz) to 30.5 µs (32.768 kHz). Its Flexible Application Accelerator (FAA) provides 32-bit signed multiply/accumulate with 33-bit internal precision and limit operation registers for real-time motor control loops.
Peripheral integration includes a 12-bit ADC with simultaneous sampling on two channels, dual 8-/10-bit DACs, four independent comparators with selectable reference sources, and dedicated 16-bit timers KB30–KB32 featuring 651-ps average PWM resolution, dithering, and PFC control modes - all synchronized via Event Link Controller (ELC) for deterministic timing in digital power applications.
