Product details
Overview
R5F101LHAFB#X0 from Renesas is a 64-pin LFQFP-0.5mm-pitch 16-bit RL78/G13 microcontroller with 128 KB flash, 12 KB RAM, and no data flash memory, operating from 1.6 V to 5.5 V across -40°C to +85°C industrial temperature range. It delivers 41 DMIPS at 32 MHz, features ultra-low-power HALT/STOP/SNOOZE modes (0.57 μA RTC+LVD), integrated 10-bit ADC (26 channels), RTC with calendar/alarm, and multiple serial interfaces including UART, I²C, and CSI.
For engineers reviewing the R5F101LHAFB#X0 datasheet, R5F101LHAFB#X0 pinout, R5F101LHAFB#X0 application, or R5F101LHAFB#X0 equivalent, key selection criteria include its 64-pin LFQFP package, absence of on-chip data flash, industrial-grade temperature support, and compatibility with Renesas' RL78 toolchain and E2 studio IDE for low-power embedded control design.
Technical Context
The R5F101LHAFB#X0 implements the RL78 CPU core with CISC architecture and 3-stage pipeline, supporting instruction execution times from 0.03125 μs (32 MHz high-speed mode) to 30.5 μs (32.768 kHz ultra-low-speed mode). Its memory map includes 1 MB address space, with flash organized in 1 KB blocks and security features like block erase prohibition.
Power management integrates on-chip POR and LVD with 14 selectable voltage detection levels, while peripheral subsystems include 16-channel 16-bit timers, 12-bit interval timer, watchdog timer with dedicated low-speed oscillator, and DMA controller with 4 channels supporting 2-clock transfers between SFR and RAM.
