Технические характеристики
R7F100GLL2DFB is a 16-bit low-power microcontroller from Renesas Electronics, belonging to the RL78/G23 product family, designed for battery-powered and industrial embedded control applications with ultra-low power consumption and rich on-chip peripherals.
Part Number Definition
The prefix R7F100G marks the RL78/G23 series core architecture. GLL corresponds to the configuration of 512KB program Flash, 48KB RAM and complete analog peripheral resources. 2DFB stands for standard commercial temperature grade, LFQFP-64 surface mount package, and factory standard tape-and-reel packaging for automated SMT assembly.
Core Processor & Memory Specifications
It adopts the 16-bit RL78 RISC core with a maximum operating main frequency up to 32MHz. The CPU running current is only 41μA per MHz, achieving outstanding energy efficiency. Program Flash memory capacity reaches 512KB for application code storage, with 8KB data Flash supporting emulated EEPROM function for parameter offline storage. Built-in 48KB high-speed SRAM, and the stop mode with 4KB RAM data retention only consumes 210nA standby current, which greatly extends the service life of battery-driven equipment.
Power Supply & Clock System
The wide input voltage range supports 1.6V to 5.5V single power supply operation, compatible with lithium battery power supply and industrial 5V power rail scenarios. The chip integrates high-precision internal main oscillator, low-speed sub oscillator and watchdog oscillator, which can work without external crystal oscillators to simplify peripheral circuit design. Multiple power management modes including stop mode, snooze sequencer and low-speed operation mode are integrated to dynamically adjust power consumption according to task load.
Integrated Peripheral Interfaces
Communication peripherals include multi-channel UART/USART, SPI, CSI and I2C bus interfaces, and it natively supports LIN bus protocol for automotive and equipment wired communication. Analog modules contain 12-channel 10-bit ADC, 8-channel 12-bit high-precision ADC and 2-channel 8-bit DAC, plus built-in voltage detection circuit and analog comparators. It is equipped with a dedicated capacitive touch sensing unit to directly drive touch buttons and slider input without extra peripheral chips. Multiple timer arrays can generate multi-channel PWM signals for motor drive, LED dimming and power switching control. Other built-in modules include power-on reset circuit, low voltage detection and independent watchdog timer to enhance system operation stability. The chip leads out 54 general-purpose I/O pins with configurable pull-up resistors and interrupt trigger functions.
Package & Mechanical Parameters
Package form is 64-pin LFQFP quad flat leaded surface mount package with dimensions of 10mm × 10mm. Moisture Sensitivity Level is MSL 3, and reflow soldering must be finished within 168 hours after opening the vacuum moisture-proof packaging bag. The lead frame structure features excellent solderability and mechanical shock resistance, adapting to mass PCB patch production.
Environmental & Compliance Standards
Commercial grade operating temperature range is -40℃ to +85℃. The product is fully lead-free and meets RoHS and REACH environmental protection regulations without restricted hazardous substances. Optimized EMC design improves anti-interference ability against electromagnetic noise, suitable for indoor consumer electronics and light industrial control environments.
