Product details
Overview
R5F102A7GSP#50 from Renesas Electronics is a 30-pin LSSOP-packaged RL78/G12 16-bit microcontroller designed for industrial embedded control at extended temperature (–40°C to +105°C). It integrates 16 KB code flash, 2 KB data flash, 2 KB RAM, 8-channel 10-bit ADC, dual UART/CSI/I²C serial interfaces, 8-channel TAU timer with PWM, and DMA controller - enabling real-time sensor fusion and motor control in HVAC actuators.
For engineers reviewing the R5F102A7GSP#50 datasheet, R5F102A7GSP#50 pinout, R5F102A7GSP#50 application, or R5F102A7GSP#50 equivalent, key selection criteria include its G-grade industrial temperature rating, on-chip 2 KB data flash supporting background rewriting (BGO), 2-channel DMA for low-CPU-overhead peripheral transfers, and hardware CRC for firmware integrity verification in safety-critical edge nodes.
Technical Context
The R5F102A7GSP#50 implements the RL78 CPU core with 3-stage pipeline CISC architecture, delivering 31 DMIPS at 24 MHz while consuming only 63 μA/MHz in active mode. Its clock system combines a high-accuracy ±1.0% (–20°C to +85°C) 24 MHz on-chip oscillator with external crystal support (1–20 MHz) and a dedicated 15 kHz low-speed oscillator for watchdog and interval timing.
Peripheral integration includes two SAU (Serial Array Unit) modules supporting UART, CSI (SPI-compatible), and I²C protocols across separate channels, plus an 8-channel TAU timer capable of simultaneous PWM generation and input capture - all managed via vectored interrupts with up to 26 internal sources and 6 external pins (INTP0–INTP5).
Key Specifications
| Parameter | Value and Actual Design Meaning |
