It features 64 KB flash, 6 KB RAM, 2 KB data flash, independent-power-supply RTC, and hardware AES encryption - all operating from 1.9 V to 5.5 V across –40°C to +85°C.
For engineers reviewing the R5F11TLEDFB#30 datasheet, R5F11TLEDFB#30 pinout, R5F11TLEDFB#30 application, or R5F11TLEDFB#30 equivalent, this MCU delivers verified low-power operation (HALT/STOP/SNOOZE modes), ΔΣ A/D converter support, LCD driver capability, and secure firmware update via self-programming with boot swap.
Technical Context
The R5F11TLEDFB#30 implements the RL78 CPU core with CISC architecture, 3-stage pipeline, and selectable minimum instruction execution time (0.03125 µs at 32 MHz PLL clock). It supports 16-bit multiplication, 16-bit MAC, and 32-bit division, with 1 MB address space and four banks of 8-bit general-purpose registers.
Its peripheral set includes an independent-power-supply RTC with calendar and alarm, 24-bit ΔΣ A/D converter (4 channels), 8-channel 16-bit timer array, UART/IrDA/CSI/I²C interfaces, and LCD controller supporting up to 19 segment × 4 common outputs in 64-pin configuration.

FAQ
What is the maximum operating frequency of the R5F11TLEDFB#30?
The R5F11TLEDFB#30 supports a maximum CPU clock of 32 MHz via its integrated PLL. This frequency is achievable with VDD = 2.8 V to 5.5 V and enables a minimum instruction execution time of 0.03125 µs. The high-speed on-chip oscillator also supports up to 24 MHz operation with ±1.0% accuracy across full temperature and voltage ranges.
Does the R5F11TLEDFB#30 include hardware AES encryption?
No, the R5F11TLEDFB#30 does not include hardware AES. Its part number prefix "11T" explicitly indicates no on-chip AES circuit, unlike "10N" variants such as R5F10NLEDFB#30. All cryptographic operations for R5F11TLEDFB#30 must be implemented in software or offloaded to external secure elements.
How many ΔΣ A/D converter channels does the R5F11TLEDFB#30 support?
The R5F11TLEDFB#30 supports four 24-bit ΔΣ A/D converter channels, accessible via dedicated ANIP0–ANIP3 and ANIN0–ANIN3 pins. These channels operate independently of the 10-bit SAR ADC and are optimized for high-precision, low-noise energy measurement in power metering applications.
What RTC backup voltage does the R5F11TLEDFB#30 require?
The R5F11TLEDFB#30 requires VRTC ≥ 1.6 V for RTC operation during main power loss. This allows use of standard 3 V lithium coin cells or supercapacitors to maintain calendar, alarm, and correction functions for over 10 years - confirmed in Renesas' R01DS0281EJ0231 datasheet Section 1.1.
Is the R5F11TLEDFB#30 pin-compatible with other RL78/I1C 64-pin variants?
Yes, the R5F11TLEDFB#30 shares identical 64-pin LFQFP mechanical dimensions and pinout with all other RL78/I1C 64-pin variants including R5F10NLEDFB#30 and R5F11TLGDFB#30. Function mapping is consistent across the family, enabling drop-in replacement where flash/RAM/AES requirements align.
