Product details
Overview
R5F101LCDFB#X0 from Renesas is a 64-pin LFQFP, 0.5-mm pitch, industrial-grade RL78/G13 16-bit microcontroller with 16 KB flash memory, 2 KB RAM, and no data flash. It operates from 1.6 V to 5.5 V, delivers 41 DMIPS at 32 MHz, and supports ultra-low-power modes (0.57 μA in RTC+LVD mode), targeting battery-powered industrial sensors and motor control interfaces.
For engineers reviewing the R5F101LCDFB#X0 datasheet, R5F101LCDFB#X0 pinout, R5F101LCDFB#X0 application, or R5F101LCDFB#X0 equivalent, key selection criteria include its 64-pin LFQFP-0.5 mm package, absence of data flash, -40°C to +85°C industrial temperature grade (D), and integrated peripherals including 16-bit timers, UART/LIN, I²C, and 10-bit ADC with 26 channels.
Technical Context
The R5F101LCDFB#X0 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). Its memory map includes 1 MB address space, on-chip RAM banked across four register banks, and flash memory organized in 1 KB blocks with security-based erase/write prohibition.
Peripherals are tightly coupled to low-power operation: the 12-bit interval timer and real-time clock (RTC) with calendar/alarm support operate independently in STOP mode; DMA controller handles 2-channel transfers in 2 clocks between SFR and RAM; and the 10-bit A/D converter features internal 1.45 V reference and selectable sampling timing for precision sensor interfacing.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F100LCDFB#X0 | Includes 4 KB data flash and same 16 KB code flash, RAM, and peripherals | Required where EEPROM-like nonvolatile parameter storage is needed (e.g., calibration data retention) | Select when field-updatable configuration storage is mandatory; otherwise R5F101LCDFB#X0 reduces BOM cost |
| R5F101LDDB#X0 | Same package and core, but 32 KB flash, 2 KB RAM, no data flash - higher code capacity | Better suited for applications requiring larger firmware (e.g., BLE stack integration or enhanced UI logic) | Choose for future-proofing firmware growth without changing PCB layout or thermal design |
Compared with R5F100LCDFB#X0, the R5F101LCDFB#X0 removes data flash to reduce cost and die size while maintaining identical low-power performance and peripheral set; versus R5F101LDDB#X0, it trades flash capacity for lower gate count and reduced static power in deeply embedded control-only roles.

FAQ
What is the operating temperature range for the R5F101LCDFB#X0?
The R5F101LCDFB#X0 is rated for industrial operation from –40°C to +85°C (D-grade), validated across full voltage (1.6 V to 5.5 V) and frequency (up to 32 MHz) ranges per Renesas datasheet R01DS0131EJ0380. This makes R5F101LCDFB#X0 suitable for factory-floor automation and outdoor metering environments where ambient extremes are expected.
Does the R5F101LCDFB#X0 include data flash memory?
No, the R5F101LCDFB#X0 does not include data flash memory - this is confirmed by the part number coding convention ("101" denotes no data flash) and verified in Table 1-1 of the RL78/G13 datasheet. The R5F101LCDFB#X0 provides 16 KB code flash and 2 KB RAM only; for data logging or parameter storage, external EEPROM or the R5F100LCDFB#X0 variant (with 4 KB data flash) must be used.
Which package type and pin pitch does the R5F101LCDFB#X0 use?
The R5F101LCDFB#X0 uses a 64-pin LFQFP package with 0.5 mm pin pitch, as indicated by the "FB" suffix in the part number and confirmed in Table 1-1 (Page 10) of the RL78/G13 datasheet. Its footprint matches PLQP0064KF-A land pattern, and it is supplied in embossed tape (#X0 packaging specification), compatible with standard SMT pick-and-place equipment.
Can the R5F101LCDFB#X0 operate without an external crystal?
Yes, the R5F101LCDFB#X0 integrates a high-accuracy on-chip oscillator (±1.0% over 1.8–5.5 V and –20 to +85°C) supporting frequencies from 1 MHz to 32 MHz. This allows full operation - including UART communication at standard baud rates and RTC timekeeping - without any external crystal or resonator, reducing BOM cost and board space for the R5F101LCDFB#X0.
What debug interface does the R5F101LCDFB#X0 support?
The R5F101LCDFB#X0 supports on-chip debugging via the dedicated TOOLnTRST (P30) and TOOLRxD (P11) pins, compatible with Renesas E2 emulator and CS+ IDE. It does not support SWD or JTAG; instead, it uses Renesas' proprietary single-wire debug protocol, enabling full breakpoint, watchpoint, and memory inspection capabilities without additional interface ICs for the R5F101LCDFB#X0.
