Product details
Overview
R5F100JFDFA#X0 from Renesas Electronics is a 52-pin LQFP-0.65mm MCU in the RL78/G13 family, featuring a 16-bit CISC CPU core, 256 KB flash memory, 8 KB data flash, and 20 KB RAM. It operates from 1.6 V to 5.5 V, delivers 41 DMIPS at 32 MHz, and supports ultra-low-power modes including STOP (0.57 μA) and HALT (66 μA/MHz), targeting battery-powered industrial control and sensor interface applications.
For engineers reviewing the R5F100JFDFA#X0 datasheet, R5F100JFDFA#X0 pinout, R5F100JFDFA#X0 application, or R5F100JFDFA#X0 equivalent, key selection criteria include its integrated RTC with calendar function, 12-bit ADC (26-channel), dual UART/LIN support, and 52-pin LQFP package with industrial-grade temperature range (−40°C to +85°C).
Technical Context
The R5F100JFDFA#X0 implements the RL78 CPU core with a 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 subsystem includes 256 KB code flash (1 KB block size), 8 KB background-operable data flash (1M rewrite cycles), and 20 KB SRAM - enabling robust firmware updates and real-time data logging without halting program execution.
Peripherals are tightly integrated for embedded control: dual UART/LIN channels, up to 10 I²C interfaces, 8–16 × 16-bit timers (including RTC with alarm/calendar), and a 12-bit A/D converter with internal reference (1.45 V) and temperature sensor. Power management includes on-chip POR, 14-level LVD, and SNOOZE mode for low-latency wake-up from deep sleep.
