Product details
Overview
R5F101GLDFB#10 from Renesas is a 48-pin LFQFP-packaged 16-bit RL78/G13 microcontroller with 128 KB flash, 8 KB RAM, and no data flash memory, operating from 1.6 V to 5.5 V across -40°C to +105°C industrial temperature range. It delivers 41 DMIPS at 32 MHz, integrates 16-bit timers (12 channels), 10-bit ADC (26 channels), RTC, UART, I²C, and CSI interfaces, and targets low-power industrial control and sensor node applications.
For engineers reviewing the R5F101GLDFB#10 datasheet, R5F101GLDFB#10 pinout, R5F101GLDFB#10 application, or R5F101GLDFB#10 equivalent, key selection criteria include its industrial-grade temperature rating (−40°C to +105°C), absence of on-chip data flash, 48-pin LFQFP-0.5 mm pitch package, and support for ultra-low-power STOP/HALT modes down to 0.57 μA.
Technical Context
The R5F101GLDFB#10 implements the RL78 CPU core with CISC architecture and 3-stage pipeline, enabling 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 map spans 1 MB address space, with 128 KB code flash organized in 1 KB blocks supporting secure erase prohibition and self-programming with boot swap.
Power management includes on-chip POR and LVD with 14 selectable voltage detection levels, DMA controller (4 channels), and real-time clock with calendar, alarm, and clock correction functions. Peripheral integration covers 12× 16-bit timers, 10-bit A/D converter with internal reference and temperature sensor, and up to 10-channel simplified I²C/SI²C operation.

FAQ
What is the maximum operating frequency and performance of the R5F101GLDFB#10?
The R5F101GLDFB#10 operates at up to 32 MHz and delivers 41 DMIPS. Its RL78 CPU core achieves minimum instruction execution times of 0.03125 μs in high-speed mode (32 MHz with on-chip oscillator) and 30.5 μs in ultra-low-speed mode (32.768 kHz). This performance enables deterministic real-time control in industrial and sensor applications while maintaining low power consumption.
Does the R5F101GLDFB#10 include on-chip data flash memory?
No, the R5F101GLDFB#10 does not include on-chip data flash memory. Per the RL78/G13 family naming convention, part numbers beginning with "R5F101" indicate devices without data flash, whereas "R5F100" variants include 4–8 KB. The R5F101GLDFB#10 retains 128 KB of code flash and 8 KB of RAM, but requires external nonvolatile storage for parameter retention or firmware updates.
What is the operating temperature range and qualification grade for R5F101GLDFB#10?
The R5F101GLDFB#10 is rated for −40°C to +105°C and belongs to the industrial "G" grade per Renesas' RL78/G13 ordering nomenclature. This qualification ensures reliability in demanding environments such as factory automation equipment, under-hood automotive subsystems, and outdoor utility infrastructure where extended thermal stress is expected.
Which serial communication interfaces are supported by the R5F101GLDFB#10?
The R5F101GLDFB#10 supports multiple serial interfaces: up to 10 channels of simplified I²C (SI²C), up to 4 channels of UART/LIN, and up to 8 channels of CSI (a SPI-compatible interface). Pin multiplexing allows flexible allocation-for example, P10/P11 can serve as SCK00/SDA00 (I²C), SCK00/RxD0 (UART), or SCK00/SI00 (CSI)-enabling compact peripheral integration without additional bridge ICs.
What low-power modes are available on the R5F101GLDFB#10 and their typical current consumption?
The R5F101GLDFB#10 supports HALT mode (66 μA/MHz), STOP mode (0.57 μA with RTC and LVD active), and SNOOZE mode (low-power background operation during ADC or serial transfers). These modes are hardware-controlled and retain RAM content and register states, allowing rapid wake-up (< 4 μs from HALT) - ideal for battery-powered sensing and metering applications requiring multi-year operational life.
