Product details
Overview
R5F100SHAFB#30 from Renesas is a 128-pin LFQFP (14 × 20 mm, 0.5-mm pitch), industrial-grade RL78/G13 16-bit microcontroller with 128 KB flash memory, 8 KB data flash, 12 KB RAM, and operation up to 32 MHz delivering 41 DMIPS - deployed in battery-powered HVAC controllers, smart metering interfaces, and industrial sensor nodes requiring ultra-low power (66 μA/MHz active, 0.57 μA RTC+LVD mode).
For engineers reviewing the R5F100SHAFB#30 datasheet, R5F100SHAFB#30 pinout, R5F100SHAFB#30 application, or R5F100SHAFB#30 equivalent, key selection criteria include its integrated 10-bit 26-channel ADC, real-time clock with calendar/alarm, hardware multiplier/divider, dual UART/LIN support, and 16-bit timer array - all within a -40°C to +105°C operating range and 1.6–5.5 V supply.
Technical Context
The R5F100SHAFB#30 implements the RL78 CPU core with 3-stage pipeline CISC architecture, supporting instruction execution times from 0.03125 μs (32 MHz high-speed oscillator) to 30.5 μs (32.768 kHz subsystem clock). It integrates on-chip debug, self-programming flash with boot swap and flash shield window functions, and background operation for data flash rewriting.
Its peripheral set includes up to 16 channels of 16-bit timers, 3–10 I²C/Simplified I²C channels, 2–4 UART/LIN interfaces, 2–8 CSI (SPI-compatible) channels, and DMA controller with 4 channels - enabling deterministic real-time control in resource-constrained embedded systems without external timing or interface ICs.
