Product details
Overview
R5F101SJDFB#10 from Renesas is a 128-pin LFQFP (14 × 20 mm, 0.5-mm pitch), industrial-grade RL78/G13 16-bit microcontroller with 64 KB flash memory, 4 KB data flash, 2 KB RAM, and operation from −40°C to +85°C. It integrates a 32-MHz RL78 CPU core delivering 41 DMIPS, ultra-low-power modes (0.57 μA in RTC+LVD mode), 10-bit ADC (26 channels), real-time clock, and multiple serial interfaces including UART, I²C, and CSI for embedded control in resource-constrained environments.
For engineers reviewing the R5F101SJDFB#10 datasheet, R5F101SJDFB#10 pinout, R5F101SJDFB#10 application, or R5F101SJDFB#10 equivalent, key selection criteria include its 128-pin LFQFP-0.5mm package, absence of on-chip data flash (R5F101x series), industrial temperature rating (D grade), and compatibility with Renesas' RL78 toolchain and E2 studio IDE for rapid firmware development and low-power system optimization.
Technical Context
The R5F101SJDFB#10 implements the RL78 CPU core with CISC architecture, 3-stage pipeline, and configurable instruction timing (0.03125 μs at 32 MHz to 30.5 μs at 32.768 kHz). It supports HALT, STOP, and SNOOZE low-power modes and includes an on-chip high-accuracy ±1.0% oscillator (1–32 MHz selectable).
It features 26-channel 10-bit A/D conversion with internal 1.45-V reference and temperature sensor, 16-bit timers (12 channels), real-time clock with calendar/alarm, and up to 10 I²C/Simplified I²C channels - all operating across 1.6–5.5 V supply range and validated for industrial ambient conditions (−40°C to +85°C).

IC Role / Device Role / Timing Role: Main system controller managing ADC sampling, RTC-timed sleep/wake cycles, UART-to-BLE bridge, and low-power state transitions. Use Value: 0.57 μA STOP mode with RTC extends battery life beyond 5 years; integrated 10-bit ADC and 26-channel input eliminate external signal conditioning ICs. |
Use Scenario: Wall-mounted HVAC thermostat with display, relay control, and environmental sensing. IC Role / Device Role / Timing Role: Central MCU handling user interface (key interrupt, buzzer output), fan speed control (PWM via 16-bit timers), and multi-sensor fusion (temp, humidity, occupancy). Use Value: On-chip key interrupt and buzzer controller reduce BOM count; 12 16-bit timers support simultaneous motor control, display refresh, and sensor polling without external timing ICs. |
| Programmable Logic Controller (PLC) I/O Module | Energy Metering Subsystem |
Use Scenario: DIN-rail mounted digital I/O expansion module with opto-isolated inputs/outputs and Modbus RTU communication. IC Role / Device Role / Timing Role: Protocol processor and I/O manager executing Modbus slave stack, scanning discrete inputs, and driving output latches via GPIO. Use Value: 128-pin package provides ≥80 GPIOs (including N-ch open-drain outputs rated to 6 V), enabling direct drive of optocouplers without buffer transistors. |
Use Scenario: Secondary metering unit in smart electricity meters performing auxiliary functions like tamper detection, event logging, and LCD backlight control. IC Role / Device Role / Timing Role: Co-processor handling non-critical metering tasks while main metrology MCU focuses on precision ADC sampling and calculations. Use Value: 1.6–5.5 V wide supply range allows direct connection to meter's internal 3.3 V or 5 V rail; integrated RTC ensures accurate timestamping of power outage events. |
