Product details
Overview
R5F101SJDFB#30 from Renesas is a 32-bit RL78/G13 microcontroller with no data flash memory, 128 KB code flash, 12 KB RAM, and 64-pin LFQFP (0.5 mm pitch) package. It operates from 1.6–5.5 V, delivers 41 DMIPS at 32 MHz, and supports ultra-low-power modes including STOP (0.57 μA) and HALT for battery-powered industrial sensors and metering systems.
For engineers reviewing the R5F101SJDFB#30 datasheet, R5F101SJDFB#30 pinout, R5F101SJDFB#30 application, or R5F101SJDFB#30 equivalent, key selection criteria include its 64-pin LFQFP-0.5mm footprint, absence of on-chip data flash, integrated RTC with calendar/alarm, 26-channel 10-bit ADC, and support for LIN-bus UART and I²C interfaces in industrial temperature grade (−40°C to +85°C).
Technical Context
The R5F101SJDFB#30 implements the RL78 CPU core with CISC architecture, 3-stage pipeline, and configurable instruction timing (0.03125 μs min @ 32 MHz). It integrates a 12-bit interval timer, real-time clock with 99-year calendar, and watchdog timer driven by a dedicated low-speed oscillator.
Peripheral integration includes up to 16 channels of 16-bit timers, 3–10 I²C/Simplified I²C channels, 2–4 UART/LIN channels, and 2–8 CSI (SPI-compatible) interfaces - all accessible via 64 I/O pins with N-ch open-drain capability, TTL input buffers, and on-chip pull-up resistors.
