Overview
R5F11EBAAFP#10 from Renesas Electronics is a 32-pin LQFP ultra-low-power 16-bit RL78/G1G microcontroller with 16 KB flash, 1.5 KB RAM, and integrated peripherals including dual UART, simplified SPI (CSI), simplified I²C, 12-channel 10-bit ADC, two comparators, PGA, and ELC-designed for battery-powered consumer and industrial control applications requiring extended runtime and compact footprint.
For engineers reviewing the R5F11EBAAFP#10 datasheet, R5F11EBAAFP#10 pinout, R5F11EBAAFP#10 application, or R5F11EBAAFP#10 equivalent, this page delivers verified technical context, package-validated pin functions, real-world use cases, and two confirmed alternative parts with documented functional and application-level distinctions.
Technical Context
The R5F11EBAAFP#10 implements the RL78 CPU core with 3-stage pipeline CISC architecture, supporting 1 MB address space and instruction execution as fast as 0.04167 µs at 24 MHz (high-speed on-chip oscillator). It integrates a voltage regulator with REGC pin, POR/LVD reset circuitry, and low-power modes (HALT, STOP, SNOOZE) enabling sub-µA standby current.
Peripheral integration includes Timer Array Unit (TAU) with four 16-bit channels, Timer RJ (1 channel), Timer RD (2 channels), 12-bit interval timer, watchdog timer, and Event Link Controller (ELC) supporting 19 event inputs and 6 trigger outputs-enabling deterministic peripheral chaining without CPU intervention.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Core Architecture | RL78 16-bit CISC with 3-stage pipeline; enables deterministic timing and efficient code density for resource-constrained embedded systems |
| Flash / RAM | 16 KB code flash (1 KB block size) + 1.5 KB on-chip RAM; supports self-programming with flash shield window for secure firmware updates |
| Operating Voltage | 2.7 V to 5.5 V single supply; compatible with Li-ion, alkaline, and regulated 3.3 V/5 V rails without external level-shifting |
| ADC Resolution | 10-bit A/D converter with 12 analog inputs (ANI0–ANI7, ANI16–ANI19); includes internal 1.45 V reference and temperature sensor for sensor node calibration |
| Serial Interfaces | UART0 + UART1 (2 full-duplex channels), simplified SPI (CSI), simplified I²C (IIC00); supports mixed-protocol communication in home appliance and metering designs |
| Low-Power Modes | HALT, STOP, and SNOOZE modes with wake-up via 6 external interrupts (INTP0–INTP5) or peripheral events; reduces active current to < 100 µA typical in STOP mode |
| Package & Pins | 32-pin LQFP (7 × 7 mm, 0.8 mm pitch); provides 28 total I/O pins (25 CMOS I/O + 3 CMOS input), including N-ch open-drain capable ports for mixed-voltage interfacing |
Pinout & Package
32-pin plastic LQFP (7 × 7 mm, 0.8 mm pitch) with REGC capacitor pad requirement (0.47–1 µF to VSS). Pin functions validated per R01DS0241EJ0150 Rev. 1.50 Figure 1.3.2 and Table 1.4.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
