Renesas R5F100LEABG#U0

Overview

R5F100LEABG#U0 from Renesas is a 64-pin VFBGA-packaged RL78/G13 16-bit microcontroller with 64 KB flash, 4 KB data flash, 4 KB RAM, 16 MHz max CPU frequency, and industrial-grade -40°C to +105°C operation. It integrates 12-bit ADC (10-bit mode), RTC, UART, I²C, SPI, 16-bit timers, and ultra-low-power modes (0.57 μA in STOP with RTC+LVD) for embedded control in space-constrained industrial sensors and power management systems.

For engineers reviewing the R5F100LEABG#U0 datasheet, R5F100LEABG#U0 pinout, R5F100LEABG#U0 application, or R5F100LEABG#U0 equivalent, key selection criteria include its VFBGA-64 (4 × 4 mm, 0.4 mm pitch) footprint, integrated data flash rewrite capability (1M cycles), real-time clock with calendar/alarm, and support for LIN-bus via UART - all critical for compact, battery-backed industrial monitoring designs.

Technical Context

The R5F100LEABG#U0 implements the RL78 CPU core with CISC architecture, 3-stage pipeline, and configurable instruction timing (0.03125 μs @ 32 MHz to 30.5 μs @ 32.768 kHz). It supports background operation during data flash rewriting and uses on-chip debug with boot swap functionality.

Its peripheral set includes up to 16 channels of 16-bit timer, 1 channel of 12-bit interval timer, 1 RTC with calendar and clock correction, 1 watchdog timer, and serial interfaces: 2–4 UART/LIN, 2–8 CSI (SPI-compatible), and 3–10 I²C/Simplified I²C channels - all mapped to dedicated pins in the 64-pin VFBGA package.

FAQ

What is the maximum operating frequency of the R5F100LEABG#U0?

The R5F100LEABG#U0 supports a maximum CPU clock frequency of 16 MHz using its high-speed on-chip oscillator, which maintains ±1.0% accuracy across VDD = 1.8–5.5 V and TA = –20°C to +85°C. This frequency is configurable via system clock settings and aligns with the RL78/G13 family's 41 DMIPS @ 32 MHz specification scaled to 16 MHz operation.

Does the R5F100LEABG#U0 include an integrated temperature sensor?

Yes, the R5F100LEABG#U0 includes an on-die temperature sensor usable in HS (high-speed main) mode, with typical accuracy of ±3°C over the full industrial temperature range (–40°C to +105°C). The sensor output is accessible via dedicated ADC channel ANI19 and requires no external components for basic thermal monitoring.

Can the R5F100LEABG#U0 operate from a 1.8 V supply?

Yes, the R5F100LEABG#U0 operates across a 1.6 V to 5.5 V supply range, fully supporting 1.8 V VDD. At this voltage, it maintains full functionality including 16 MHz operation, data flash programming (VDD ≥ 1.8 V), and all low-power modes - verified per R01DS0131EJ0380 Rev.3.80 specifications.

What is the data flash endurance rating for the R5F100LEABG#U0?

The R5F100LEABG#U0 specifies 1,000,000 write/erase cycles (typical) for its 4 KB data flash memory, with guaranteed operation across VDD = 1.8–5.5 V. This endurance enables reliable storage of calibration data, device configuration, or usage logs in applications requiring frequent nonvolatile updates.

Is the R5F100LEABG#U0 pin-compatible with other RL78/G13 64-pin variants?

Yes, the R5F100LEABG#U0 shares identical pinout and package (VFBGA-64, 4 × 4 mm, 0.4 mm pitch) with all other RL78/G13 devices ending in "ABG#U0", including R5F100LCABG#U0 through R5F100LJABG#U0 and their data-flash-less counterparts (e.g., R5F101LEABG#U0), enabling drop-in replacement within the same memory/peripheral subset.
