Product details
Overview
R5F101GJDFB#V0 from Renesas is a 48-pin LFQFP-packaged RL78/G13 16-bit microcontroller with 192 KB flash, 8 KB data flash, 16 KB RAM, 52-channel 10-bit ADC, and real-time clock - designed for ultra-low-power industrial control applications operating from 1.6 V to 5.5 V across –40°C to +85°C.
For engineers reviewing the R5F101GJDFB#V0 datasheet, R5F101GJDFB#V0 pinout, R5F101GJDFB#V0 application, or R5F101GJDFB#V0 equivalent, key selection criteria include its 192 KB code flash with self-programming, 16 KB RAM for real-time firmware execution, integrated RTC with calendar/alarm, and support for UART/LIN, I²C, and CSI interfaces in a compact 7 mm × 7 mm 0.5-mm-pitch package.
Technical Context
The R5F101GJDFB#V0 implements the RL78 CPU core with 3-stage pipeline CISC architecture, supporting instruction execution times from 0.03125 μs (32 MHz high-speed mode) to 30.5 μs (32.768 kHz ultra-low-speed mode). It integrates a 12-bit interval timer, 16-bit timers (12 channels), watchdog timer, and DMA controller with 4 channels for efficient peripheral-to-memory transfers.
Its power management includes HALT, STOP, and SNOOZE modes, achieving 66 μA/MHz active current and 0.57 μA RTC+LVD retention current. The on-chip high-accuracy oscillator delivers ±1.0% stability over VDD = 1.8–5.5 V and TA = –20 to +85°C, eliminating need for external crystals in many cost-sensitive designs.
