Product details
Overview
R5F102A8GSP#50 from Renesas Electronics is a 30-pin LSSOP-packaged RL78/G12 16-bit MCU designed for industrial embedded control at -40°C to +105°C. It integrates 8 KB code flash, 2 KB data flash, 512 B RAM, 8-channel 10-bit ADC, and dual UART/CSI/I²C serial interfaces - enabling compact sensor node and motor control applications with background data flash rewriting.
For engineers reviewing the R5F102A8GSP#50 datasheet, R5F102A8GSP#50 pinout, R5F102A8GSP#50 application, or R5F102A8GSP#50 equivalent, key selection criteria include its G-grade temperature rating, on-chip CRC and RAM/SFR guard safety features, 2-channel DMA support, and true low-power operation (63 μA/MHz) across 1.8–5.5 V supply.
Technical Context
The R5F102A8GSP#50 implements the RL78 CPU core with 3-stage pipeline CISC architecture, supporting minimum instruction execution time of 0.04167 μs at 24 MHz (high-speed on-chip oscillator). Its memory subsystem includes 8 KB code flash (1 KB block size), 2 KB data flash with background operation (BGO), and 512 B RAM - all accessible within a 1 MB address space.
Peripherals are organized around TAU0 timer (8 channels), SAU0 serial array (4 channels), and dedicated hardware blocks including multiplier/divider, BCD correction, and on-chip debug. Power management includes HALT/STOP/SNOOZE modes, POR, and 12-level voltage detector - all qualified for industrial ambient operation up to +105°C.
