Product details
Overview
R7F101GAE4CSP#AA1 from Renesas is a 30-pin LSSOP-packaged RL78/G24 16-bit MCU 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-channel), DALI-2 interface, and KB30/KB31/KB32 complementary PWM timers - deployed in digital power supplies and LED lighting controllers.
For engineers reviewing the R7F101GAE4CSP#AA1 datasheet, R7F101GAE4CSP#AA1 pinout, R7F101GAE4CSP#AA1 application, or R7F101GAE4CSP#AA1 equivalent, key selection criteria include its 30-pin LSSOP package, –40°C to +125°C industrial temperature grade (4C), 64 KB flash capacity, DALI-2 compliance, and integrated KB-series high-resolution PWM for PFC and multi-phase lighting drivers.
Technical Context
The R7F101GAE4CSP#AA1 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 dedicated 32-bit signed arithmetic and limit operations, sharing 32-byte memory with the CPU for real-time motor control loops.
Peripheral integration includes two 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) delivering 651-ps average resolution at 96 MHz with dithering - enabling precise timing for digital power supply gate driving and DALI-2 bus arbitration.
