Product details
Overview
R7F101GAE3CSP#AA1 from Renesas is a 30-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 for motor control acceleration, dual DACs, 23-channel 12-bit ADC, four comparators, and DALI-2 interface - deployed in digital power supplies and LED lighting controllers.
For engineers reviewing the R7F101GAE3CSP#AA1 datasheet, R7F101GAE3CSP#AA1 pinout, R7F101GAE3CSP#AA1 application, or R7F101GAE3CSP#AA1 equivalent, key selection criteria include its 30-pin LSSOP package, –40 to +105°C industrial temperature grade, integrated DALI-2 transceiver capability, and FAA-assisted real-time PWM timing for PFC and multi-phase lighting drivers.
Technical Context
The R7F101GAE3CSP#AA1 implements the RL78 CPU core with CISC architecture and 3-stage pipeline, supporting instruction execution from 0.02083 µs (48 MHz) to 30.5 µs (32.768 kHz). Its Flexible Application Accelerator (FAA) provides dedicated 32-bit signed arithmetic and limit operations, sharing 32-byte memory with the CPU for synchronized motor control loops.
Peripheral integration includes six I²C/Simplified I²C interfaces, two UART/LIN channels, one DALI-2 interface, and timer subsystems featuring KB30–KB32 complementary-output timers with 651-ps average PWM resolution at 96 MHz - enabling precise dithering and forced-stop triggering via comparator events for lighting and power applications.
