Product details
Overview
R5F101LEAFA#10 from Renesas is a 64-pin LQFP-0.65mm, 16-bit RL78/G13 microcontroller with 64 KB flash, 4 KB data flash, and 4 KB RAM, operating from 1.6–5.5 V at -40°C to +85°C. It delivers 41 DMIPS at 32 MHz, features ultra-low power consumption (66 μA/MHz active, 0.57 μA RTC+LVD), and integrates 16-bit timers, 10-bit ADC (26 channels), UART/I²C/CSI interfaces, and real-time clock.
For engineers reviewing the R5F101LEAFA#10 datasheet, R5F101LEAFA#10 pinout, R5F101LEAFA#10 application, or R5F101LEAFA#10 equivalent, key selection criteria include its no-data-flash configuration, industrial-grade temperature range, LQFP-64 package compatibility, and support for low-power sensor node and motor control firmware deployment.
Technical Context
The R5F101LEAFA#10 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 subsystem clock). It uses on-chip high-accuracy ±1.0% oscillator and includes dedicated hardware blocks for DMA (4 channels), multiply-accumulate, and background data flash rewriting.
Power management includes HALT, STOP, and SNOOZE modes; reset functions integrate POR and selectable 14-level LVD; peripheral set includes up to 16× 16-bit timers, 1× real-time clock with calendar/alarm, and 1× watchdog timer with independent low-speed oscillator.

FAQ
What is the maximum operating frequency of the R5F101LEAFA#10?
The R5F101LEAFA#10 operates at up to 32 MHz using its on-chip high-accuracy oscillator, delivering 41 DMIPS of processing performance. This frequency is fully supported across the rated voltage range (1.6–5.5 V) and temperature range (-40°C to +85°C), enabling deterministic real-time execution for motor control and sensor fusion tasks in the R5F101LEAFA#10.
Does the R5F101LEAFA#10 include data flash memory?
No, the R5F101LEAFA#10 does not include on-chip data flash memory. The "101" in the part number explicitly denotes absence of data flash, distinguishing it from "100" variants like R5F100LEAFA#10 which provide 8 KB. This design choice reduces cost and power in applications where parameters are factory-programmed or stored externally, as confirmed in the RL78/G13 datasheet revision 3.80.
What package type and pin count does the R5F101LEAFA#10 use?
The R5F101LEAFA#10 uses a 64-pin LQFP package with 0.65-mm pitch (RENESAS code PLQP0064JA-A), measuring 12 × 12 mm. This package is RoHS-compliant, surface-mountable, and includes an exposed thermal pad for enhanced heat dissipation - a key mechanical and thermal specification verified in Table 1-1 of the RL78/G13 datasheet.
What is the operating temperature range for the R5F101LEAFA#10?
The R5F101LEAFA#10 is rated for industrial operation from -40°C to +85°C, indicated by the "A" suffix in its part number per Figure 1-1 of the RL78/G13 datasheet. This temperature grade is validated for continuous operation under industrial ambient conditions and is distinct from the extended -40°C to +105°C "G" grade variants.
Which communication interfaces are integrated into the R5F101LEAFA#10?
The R5F101LEAFA#10 integrates UART (up to 4 channels), I²C/Simplified I²C (up to 10 channels), and CSI (Simplified SPI, up to 8 channels). These interfaces support concurrent peripheral connectivity - for example, UART for host communication, I²C for sensor registers, and CSI for display or memory expansion - all without external logic, as specified in Section 1.1 of the R01DS0131EJ0380 datasheet.
