It delivers 41 DMIPS at 32 MHz, consumes 66 μA/MHz active and 0.57 μA in RTC+LVD-only mode, and targets battery-powered industrial sensors, motor control interfaces, and smart metering endpoints.
For engineers reviewing the R5F101GLDFB#30 datasheet, R5F101GLDFB#30 pinout, R5F101GLDFB#30 application, or R5F101GLDFB#30 equivalent, key selection criteria include its 48-pin LFQFP-0.5mm package, absence of on-chip data flash, 128 KB/12 KB flash/RAM allocation, integrated RTC with calendar support, and dual UART/LIN capability for fieldbus-connected devices.
Technical Context
The R5F101GLDFB#30 implements the RL78 CPU core with a 3-stage CISC pipeline, supporting instruction execution times from 0.03125 μs (32 MHz high-speed oscillator) to 30.5 μs (32.768 kHz subsystem clock). Its memory map spans 1 MB, with dedicated SFRs and banked general-purpose registers (8×8-bit × 4 banks).
It integrates 16-bit timers (12 channels), a 12-bit interval timer, real-time clock with alarm/calendar, 10-bit ADC (26-channel), 3× I²C/Simplified I²C, 2× UART/LIN, 2× CSI/SPI, DMA (4 channels), and hardware multiplier/divider - all operating across 1.6–5.5 V supply and -40°C to +105°C ambient range.

FAQ
Does R5F101GLDFB#30 include on-chip data flash memory?
No, R5F101GLDFB#30 does not include on-chip data flash memory. The "1" in the part number denotes absence of data flash, distinguishing it from R5F100x variants which integrate 4–8 KB. Firmware must use external non-volatile memory or reserve code flash sectors for parameter storage. This design reduces cost and die size while maintaining full code flash capacity at 128 KB.
What is the maximum operating temperature specification for R5F101GLDFB#30?
R5F101GLDFB#30 is rated for industrial operation from -40°C to +105°C. The "G" suffix in the part number explicitly indicates this extended temperature grade, qualifying it for under-hood automotive modules, factory-floor controllers, and outdoor metering equipment where ambient thermal stress exceeds standard commercial ranges.
Which oscillator options are supported by R5F101GLDFB#30?
R5F101GLDFB#30 supports a high-accuracy on-chip oscillator selectable from 32, 24, 16, 12, 8, 6, 4, 3, 2, or 1 MHz with ±1.0% tolerance across 1.8–5.5 V and -20 to +85°C. It also supports external crystal/resonator (32.768 kHz for RTC, up to 20 MHz for main clock) and the dedicated low-speed on-chip oscillator for watchdog timer operation.
Can R5F101GLDFB#30 execute code while rewriting its own flash memory?
No, R5F101GLDFB#30 cannot execute code from flash during flash rewrite operations. Unlike variants with data flash, R5F101GLDFB#30 lacks background operation (BGO) capability. Code flash self-programming requires halting CPU execution or using RAM-resident routines. Critical real-time tasks must be paused or offloaded to peripherals during firmware updates.
How many UART/LIN interfaces does R5F101GLDFB#30 provide?
R5F101GLDFB#30 provides two UART peripherals, both fully compliant with LIN 2.2 protocol. Each supports automatic header detection, checksum calculation, and sleep/wake-up frame handling - enabling dual-node LIN communication or primary/backup bus attachment in automotive body electronics applications.
