Product details
Overview
R5F11EB8AFP#10 from Renesas is a 32-pin LQFP ultra-low-power 16-bit RL78/G1G microcontroller with 8 KB flash, 1.5 KB RAM, 28 I/O pins, 12-channel 10-bit ADC, dual comparators, and integrated programmable gain amplifier - designed for battery-powered sensor nodes and industrial control interfaces operating from 2.7–5.5 V at -40°C to +85°C.
For engineers reviewing the R5F11EB8AFP#10 datasheet, R5F11EB8AFP#10 pinout, R5F11EB8AFP#10 application, or R5F11EB8AFP#10 equivalent, this page delivers verified electrical specs, validated peripheral mapping, confirmed package dimensions (7 × 7 mm LQFP), and real-world substitution guidance for embedded firmware development and BOM optimization.
Technical Context
The R5F11EB8AFP#10 implements the RL78 CPU core with 3-stage pipeline, supporting instruction execution times from 0.04167 µs (24 MHz on-chip oscillator) to 1.0 µs (1 MHz), plus multiply/divide/accumulate instructions and 1 MB address space. It integrates a high-speed on-chip oscillator (±2% accuracy across 1–24 MHz) and low-speed 15 kHz oscillator for watchdog timing.
Peripheral integration includes Timer Array Unit (4 channels), Timer RJ (1), Timer RD (2), UART0/UART1, simplified SPI (CSI), simplified I²C, Event Link Controller (19 event inputs), and on-chip debug with flash self-programming capability - all managed via dedicated system control and voltage regulation circuitry including POR and 6-level LVD.

FAQ
What is the maximum operating frequency of the R5F11EB8AFP#10 using its internal oscillator?
The R5F11EB8AFP#10 supports a maximum high-speed on-chip oscillator frequency of 24 MHz with ±2% accuracy across -40°C to +85°C and 2.7–5.5 V supply. This enables instruction execution as fast as 0.04167 µs per cycle, sufficient for real-time UART communication at 115.2 kbps and deterministic control loop timing.
Does the R5F11EB8AFP#10 include hardware debugging support?
Yes, the R5F11EB8AFP#10 integrates an on-chip debug function compatible with Renesas E2 emulator and CS+ IDE. It supports full breakpoint control, memory inspection, and flash programming - though Renesas advises against using debug features in mass-produced end products due to flash endurance limitations.
How many analog input channels does the R5F11EB8AFP#10 support, and what is their resolution?
The R5F11EB8AFP#10 provides 12 analog input channels with 10-bit resolution, covering ANI0–ANI3 (on Port 2), ANI16–ANI19 (on Ports 0, 12, 14), and internal temperature sensor. The ADC operates across the full 2.7–5.5 V supply range and supports internal 1.45 V reference for ratiometric measurements.
Can the R5F11EB8AFP#10 drive standard 5 V logic inputs directly?
Yes - selected pins (P01, P10, P15–P17, P30, P31, P50) feature TTL-compatible input buffers with VIH thresholds as low as 1.50 V at 2.7 V supply, enabling reliable interfacing with 5 V CMOS and TTL devices without level shifters in mixed-voltage systems.
What power-saving modes are available on the R5F11EB8AFP#10, and how do they differ?
The R5F11EB8AFP#10 offers HALT (CPU stopped, peripherals active), STOP (all clocks halted except LSI, lowest power), and SNOOZE (selected peripherals remain active during low-power CPU sleep). Each mode provides distinct trade-offs between wake-up latency, peripheral responsiveness, and current consumption - down to sub-µA in STOP mode.
