Product details
Overview
R7F101GBE2DNP#AA1 from Renesas is a 32-pin 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 efficiency. It integrates FAA for motor control acceleration, dual 12-bit ADCs (23 channels), DALI-2 interface, and KB30/KB31/KB32 complementary PWM timers-targeting digital power supplies and lighting systems.
For engineers reviewing the R7F101GBE2DNP#AA1 datasheet, R7F101GBE2DNP#AA1 pinout, R7F101GBE2DNP#AA1 application, or R7F101GBE2DNP#AA1 equivalent, key selection criteria include its HWQFN-32 package, −40°C to +85°C consumer-grade temperature range, integrated DALI-2 transceiver, and 651-ps PWM resolution via dithering on KB-series timers.
Technical Context
The R7F101GBE2DNP#AA1 implements a CISC-based RL78 CPU core with 3-stage pipeline and configurable instruction timing (0.02083 µs min @ 48 MHz). Its Flexible Application Accelerator (FAA) provides dedicated 32-bit signed multiply/accumulate and limit operations, sharing 32-byte memory with the CPU for real-time motor control loops.
Peripheral integration includes two independent 12-bit ADCs with simultaneous sampling on two channels, four comparators with selectable D/A or external reference, and three 16-bit complementary PWM timers (KB30–KB32) supporting PFC control, interleaved operation, and forced output stop triggered by comparator events.
