Product details
Overview
R5F100MHAFB#V0 from Renesas is an RL78/G13 8-bit microcontroller with 128 KB flash, 12 KB RAM, and 80-pin LFQFP (0.5 mm pitch) package, operating from 1.6–5.5 V at -40°C to +105°C. It delivers 41 DMIPS @ 32 MHz, features ultra-low power consumption (66 μA/MHz active, 0.57 μA RTC+LVD), integrated 10-bit ADC (26 channels), real-time clock, and multiple serial interfaces including UART, I²C, and CSI.
For engineers reviewing the R5F100MHAFB#V0 datasheet, R5F100MHAFB#V0 pinout, R5F100MHAFB#V0 application, or R5F100MHAFB#V0 equivalent, key selection criteria include industrial-grade temperature support (−40°C to +105°C), on-chip data flash (8 KB), self-programming capability, and hardware DMA (4 channels) for deterministic sensor/data acquisition systems.
Technical Context
The R5F100MHAFB#V0 implements the RL78 CPU core with a 3-stage pipeline, supporting instruction execution times from 0.03125 μs (@32 MHz HS oscillator) to 30.5 μs (@32.768 kHz subsystem clock). Its memory architecture includes 128 KB code flash (1 KB block size), 8 KB data flash with background operation (BGO), and 12 KB SRAM - all accessible within a unified 1 MB address space.
Peripherals are tightly coupled to low-power operation: HALT/STOP/SNOOZE modes, 14-level LVD with interrupt/reset options, 16-bit timer array (12 channels), real-time clock with calendar/alarm, and dual-channel watchdog timers (main + dedicated low-speed oscillator). Serial interfaces include up to 4 UART/LIN, 10 I²C/Simplified I²C, and 8 CSI channels - configurable without external components.
